Santos-Silva & Nascimento (2018Santos-Silva, A. & Nascimento, F. E. L. 2018. Synonymies, transferences, redescriptions and new species in Lamiinae (Coleoptera, Cerambycidae). Zootaxa 4462(2):192-210.) called attention to the chaotic taxonomic status of some genera in Lamiinae (Cerambycidae) and to the problematic delimitation of its tribes, especially Acanthoderini and Desmiphorini. Through the study of both, new and already described species, it is possible to see the fragility of the limits between those two tribes, as defined by some authors (e.g.Lacordaire, 1872Lacordaire, J. T. 1872. Histoire Naturelle des Insectes. Genera des Coléoptères, ou exposé méthodique et critique de tous les genres proposés jusqu’ici dans cet ordre d’insectes. Vol. 9(2).

According to Marinoni (1972Marinoni, R. C. 1972. Estudo monográfico do gênero Tapeina Lep. & Serv., 1828 (Coleoptera, Cerambycidae). Boletim da Universidade Federal do Paraná (Zoologia) 5(1):1-76.) (translated): “Thomson, Bates, and Breuning related Tapeinini with Desmiphorini, while Serville, Laporte and Lacordaire indicated its relationship with Enicodini.” However, this statement is not entirely true. Thomson (1857)Thomson, J. 1857. Monographie du groupe des tapeinites, de la famille des cérambycides (longicornes). Archives Entomologiques 1:39-44. only reported that (translated): “it would be difficult, in the present state of the classification of Cerambycids, to assign to the Tapeinites a place other than among the Lamiites.” Thomson (1860Thomson, J. 1860. Essai d’une classification de la famille des cérambycides et matériaux pour servir a une monographie de cette famille. Paris, Bouchard-Huzard. 128p.:349) did not provide a clear relation between Tapeinini and Desmiphorini, however, the author demonstrates a certain similarity of both with old-world groups (translated): “It is incontestable that Enicodes attaches the Tmesisternites to the Saperdites by Desmiphorites, and especially by the Tapeinites… It can therefore be said that the Tmesisternites must be placed between the Saperdites and the true Lamiites.” In the same work, Thomson (1860Thomson, J. 1860. Essai d’une classification de la famille des cérambycides et matériaux pour servir a une monographie de cette famille. Paris, Bouchard-Huzard. 128p.:71) by discussing on Desmiphoritae stated (translated): “Tapeinitis: 1, frons in male unarmed; 2, prothorax laterally spinose, different.” Thomson (1864-1865)Thomson, J. 1864-1865. Systema cerambycidarum ou exposé de tous les genres compris dans la famille des cérambycides et familles limitrophes. Liége, H. Dessain. 578p. [1864: p. 1-352; 1865: p. 353-578]. did not provide details on his insinuated relationship between Tapeinini and Desmiphorini.

According to Bates (1866Bates, H. W. 1866: Contributions to an insect fauna of the Amazon Valley. Coleoptera: Longicornes. The Annals and Magazine of Natural History 3(17):191-202.): “This group was placed provisionally under the Saperditae, in the synopsis previously given of the Lamiaires. A more accurate examination has convinced me that it has closer affinities with the members of the Desmiphoritae. The Tapeinae, in fact, appear to be abnormally flattened forms of Exocentrinae.” Currently, Exocentrini is a synonym of Pogonocherini. Monné (2018Monné, M. A. 2018. Catalogue of the Cerambycidae (Coleoptera) of the Neotropical region. Part II. Subfamily Lamiinae. Available at <Available at http://cerambyxcat.com/ >. Accessed on January 2019.

) listed Exocentrini in the synonymy of Acanthocinini (however he neglected to remove the old synonymy with this tribe) and Pogonocherini, Bouchard et al. (2011Bouchard, P.; Bousquet, Y.; Davies, A. E.; Alonso-Zarazaga. M. A.; Lawrence, J. F.; Lyal, C. H. C.; Newton, A. F.; Reid, C. A. M.; Schmitt, M.; Ślipiński, S. A. & Smith, A. B. T. 2011: Family-group names in Coleoptera (Insecta). ZooKeys 88:1-972.) listed it in the synonymy of Pogonocherini, and Tavakilian & Chevillotte (2018Tavakilian, G. L. & Chevillotte, H. 2018. Titan: base de données internationales sur les Cerambycidae ou Longicornes. Available at <Available at http://titan.gbif.fr/index.html >. Accessed on January 2019.
http://titan.gbif.fr/index.html...
) considered Exocentrini as a distinct tribe (apparently, ignoring the synonymy proposed by Sama, 2008Sama, G. 2008. Preliminary note on the Cerambycid fauna of North Africa with the description of new taxa (Insecta, Coleoptera, Cerambycidae). Quaderno di Studi e Notizie di Storia Naturale della Romagna 27:217-245.). Subsequently, Bates (1881) changed his opinion: “I am now inclined to doubt that Tapeina has any close affinity with the Exocentrini, the anterior acetabular sutures being less tightly closed than they are in the true members of that group; and I think their true place is near Eupogonius and allies in the Desmiphorini.” Breuning (1950Breuning, S. 1950: Considérations preliminaries sur le classication des Lamiaires. Longicornia 1: 25-28. In: Lepesme, P. ed. Longicornia. Études et notes sur les longicornes. Volume I. Paris, Paul Lechevalier. 603p. ) indicated, at least, the proximity of Tapeinini and Desmiphorini. Audinet-Serville (1835Audinet-Serville, J. G. 1835: Nouvelle classification de la famille des longicornes.(suite et fin). Annales de la Société Entomologique de France 1(4):197-228.) and Lacordaire (1872Lacordaire, J. T. 1872. Histoire Naturelle des Insectes. Genera des Coléoptères, ou exposé méthodique et critique de tous les genres proposés jusqu’ici dans cet ordre d’insectes. Vol. 9(2). Paris, Librairie Encyclopédique de Roret, p. 411-930.) really considered Tapeina Lepeletier & Audinet-Serville, 1828 and Enicodes Gray, 1832 close to or related to each other. Laporte (1840Laporte, F. L. N. 1840. Histoire Naturelle des Insectes Coléoptères avec une introduction renfermant l’anatomie et la physiologie des animaux articulés, par M. Brullé; ouvrage accompagné de 155 planches gravées sur acier représentant plus de 800 sujets. Vol. 2. P. Paris, Duménil. 563p.) listed EurycephalusGray, 1831 and Enicodes as synonym of Tapeina.

Still according to Marinoni (1972)Marinoni, R. C. 1972. Estudo monográfico do gênero Tapeina Lep. & Serv., 1828 (Coleoptera, Cerambycidae). Boletim da Universidade Federal do Paraná (Zoologia) 5(1):1-76. (translated): “All the characters that are common to Tapeina and Peritapnia, also are common to the genera of Acanthoderini, such as: … mesocoxal cavities closed.” However, in the redescription of Tapeina, he reported (translated): “Mesepimeron enters the coxal cavity.” But this latter information is incorrect, because the mesocoxal cavities are closed, although the posterior angle of mesoventrite does not touch the anterior angle of the metaventrite (this shape of mesocoxal cavity more common in Desmiphorini than in Acanthoderini).

The main problem to correctly allocate Peritapnia Horn, 1894, Tapeina, and Wappesicus gen. nov., is to understand the definition of Acanthoderini, Desmiphorini (including Estolini), and Pogonocherini, without mentioning several other tribes not occurring in the American continent. Linsley & Chemsak (1985Linsley, E. G. & Chemsak, J. A. 1985. The Cerambycidae of North America. Part VII, No. 1. Taxonomy and classification of the subfamily Lamiinae, tribes Parmenini through Acanthoderini. University of California Publications in Entomology 102:1-258.) provided a key separating these three tribes. However, nearly all features used to separate them are only useful when studying North American genera, which makes the definitions of the tribes both incomplete and inaccurate. In that key, the first step where these tribes were separated is the alternative of couplet “13”: “Antennae with scape clavate”, leading to Acanthoderini; “Antennae with scape cylindrical or conical”, leading to Desmiphorini, Pogonocherini, and Estolini. This is problematic as there are genera in Acanthoderini with the scape not or only very slightly clavate, such as Exalphus Restelo et al., 2001 and Pycnomorphidiellus Tavakilian & Peñaherrera-Leiva, 2003; or genera with the shape of the scape very variable, from distinctly clavate to distinctly not clavate, as for example in OreoderaAudinet-Serville, 1835Audinet-Serville, J. G. 1835: Nouvelle classification de la famille des longicornes.(suite et fin). Annales de la Société Entomologique de France 1(4):197-228.. In the same way, Pogonocherini were separated from Estolini (currently equal to Desmiphorini) as follows: “Body short and convex, long flying hairs often present, if elongate and flying hairs absent, pronotum laterally unarmed”, leading to Pogonocherini; “Body elongate and parallel-sided, flying hairs absent; pronotum tuberculate laterally”, leading to Estolini. A study of the genera currently included in Desmiphorini indicates that the body shape, presence or absence of long setae and/or tubercle on sides of prothorax are useless as characters to separate the Desmiphorini from Pogonocherini, except for North America genera. The same problem occurs with nearly all tribes of Lamiinae because, their definitions are usually based on local genera.

When defining Acanthoderini, Linsley & Chemsak (1985Linsley, E. G. & Chemsak, J. A. 1985. The Cerambycidae of North America. Part VII, No. 1. Taxonomy and classification of the subfamily Lamiinae, tribes Parmenini through Acanthoderini. University of California Publications in Entomology 102:1-258.) affirmed: “This tribe may be recognized by the clavate scape of the antennae, prominent lateral tubercles of the pronotum, short stout body form, almost separated eyes, clavate femora and by the fringed front tarsi of the males of most genera.” The lateral tubercles of the prothorax may be very small, as in Amblysaphes Bates, 1885, or only a rounded protuberance as in Mundeu Martins & Galileo, 2008; and the body shape, and distance between upper and lower eye lobes, and femoral shape are all noticeably variable in Acanthoderini.

Sama (2008Sama, G. 2008. Preliminary note on the Cerambycid fauna of North Africa with the description of new taxa (Insecta, Coleoptera, Cerambycidae). Quaderno di Studi e Notizie di Storia Naturale della Romagna 27:217-245.) reported: “The tribe Exocentrini Pascoe, 1864Pascoe, F. P. 1864. Longicornia Malayana: or a descriptive catalogue of the species of the three longicorn families Lamiidae, Cerambycidae and Prionidae collected by Mr. A. R. Wallace in the Malay Archipelago. (Part I). The Transactions of the Entomological Society of London 3(3) 1:1-96. is usually regarded as a synonym of Acanthocinini (Aurivillius, 1923, Breuning, 1962). Exocentrus differ from palaearctic Acanthocinini by the characteristic shape of the last segment of the abdomen of females: the last two tergites are internally divided by a longitudinal, cartilaginous apodeme, beginning as a narrow lamina from the middle of the 4th sternite and ending at the apex of the 5th where it is enlarged laterally. As written above an analogous structure exists in Ceroplesis and Crossotus (Ceroplesini) as well as in other genera of Laminae [sic] such as Idactus Pascoe, 1864 (Ancylonotini), Sophronica (Apodasyini) and Pogonocherus (Pogonocherini), and never in Acanthocinini. Exocentrus and closely related genera and subgenera must be consequently transferred to the tribe Pogonocherini. According to Švácha (pers. comm.), this systematic change is supported by the immature stages morphology.” We do not know if this feature is really absent in all Acanthocinini but, probably it is another variable character. Even larval features, often indicated as differential for Acanthocinini, have been revealed as only generic variations (Sônia Casari, pers. comm.). We agree with Sama (2008)Sama, G. 2008. Preliminary note on the Cerambycid fauna of North Africa with the description of new taxa (Insecta, Coleoptera, Cerambycidae). Quaderno di Studi e Notizie di Storia Naturale della Romagna 27:217-245. that the existence of Exocentrini is incorrect, but a reliable feature that allows separating Pogonocherini, Desmiphorini and Acanthoderini has not been found. According to Nascimento et al. (2019Nascimento, F. E. N.; Santos-Silva, A. & Barclay, M. V. L. 2019. On the tribal allocation of Cosmotomidius Melzer, 1931, descriptions of new taxa of Acanthoderini and notes on some tribes of Lamiinae (Coleoptera, Cerambycidae). Journal of Natural History, in press.): “Lacordaire (1872Lacordaire, J. T. 1872. Histoire Naturelle des Insectes. Genera des Coléoptères, ou exposé méthodique et critique de tous les genres proposés jusqu’ici dans cet ordre d’insectes. Vol. 9(2). Paris, Librairie Encyclopédique de Roret, p. 411-930.) included Desmiphorini among the tribes with mesocoxal cavities open laterally, and Pogonocherini, Acanthocinini and Acanthoderini among the tribes with mesocoxal cavities closed laterally. However, the mesocoxal cavities in all genera of Desmiphorini examined by us are exactly as in the Pogonocherini and Acanthocinini: closed laterally (mesoventrite not touching metaventrite).” These authors concluded that all genera currently placed in Pogonocherini may be included in Desmiphorini and/or Acanthoderini.

The main arguments of Marinoni (1972)Marinoni, R. C. 1972. Estudo monográfico do gênero Tapeina Lep. & Serv., 1828 (Coleoptera, Cerambycidae). Boletim da Universidade Federal do Paraná (Zoologia) 5(1):1-76.to include Peritapnia in Acanthoderini and to keep Tapeinini as a distinct tribe are (translated): “… Peritapnia has in common with Acanthoderini and not with Tapeina: the anterior border of the first abdominal sternum narrowly inserted between the posterior coxae and scape piriform. Plus, the intercoxal processes is narrow, convex and in a plane much higher than the anterior portion of the respective sternum.” However, there are several problems with these statements. Firstly, the abdominal process is not narrow in Peritapnia (Figs 2, 6) as suggested. Rather, it is or may be very similar to that of Tapeina (Figs 10, 14). As previously mentioned, the scape in Acanthoderini is very variable and frequently, it is not piriform. Although the prosternal process and mesoventral process are wide in Tapeina (always wider than coxal cavity), it is more variable in Peritapnia, and although it is always narrower than coxal cavity, it may be distinctly narrower or wider than half of the coxal cavity. Furthermore, the central area of the prosternal process in the new genus described here is slightly narrower than procoxal cavity, and the narrowest area of the mesoventral process is as wide as mesocoxal cavity. The “plane” of the intercoxal processes is variable in Peritapnia, but can be similar to that in Tapeina. For example, Chemsak & Linsley (1978Chemsak, J. A. & Linsley, E. G. 1978: New Neotropical Lamiinae (Coleoptera: Cerambycidae). The Pan-Pacific Entomologist 54(1):26-30.) reported on their new species P. minima: “… intercoxal process [prosternal process] almost plane…” Finally, the new genus has features of Tapeina and Peritapnia: scape similar to Peritapnia; lateral tubercles of the prothorax acute at apex as in Peritapnia (rounded in Tapeina); intercoxal processes similar to Tapeina; meso- and metafemora nearly fusiform as in Tapeina (pedunculate-clavate in Peritapnia); and abdominal process more similar to Peritapnia (slighter wider in Tapeina, but not so wide as suggested by Marinoni, 1972Marinoni, R. C. 1972. Estudo monográfico do gênero Tapeina Lep. & Serv., 1828 (Coleoptera, Cerambycidae). Boletim da Universidade Federal do Paraná (Zoologia) 5(1):1-76.).

Based on the lack of reliable features, and especially by the existence of Wappesicus gen. nov., which clearly have intermediate features between Tapeina and Peritapnia, would be evident the synonymy, based on the characters currently proposed for Acanthoderini and Tapeinini. However, it is possible that Tapeina (Figs 9-18), Peritapnia (Figs 1-8), and the new genus (Figs 19-22) belong to Desmiphorini because the imperfectly closed mesocoxal cavities (mesoventrite not touching metaventrite), is much more common in this tribe than in Acanthoderini. Nevertheless, as indicated, this feature is variable in the species (not only genera) currently placed in those tribes. Thus, as it was not possible to know what defines and separates Acanthoderini and Desmiphorini, it is not possible to establish a synonymy with security. However, the understanding of the true separation between Acanthoderini and Desmiphorini will only be possible after an embracing study of all genera including in them, not only base in genera of a particular area of the World, as has been done, but including genera from several places. We are being conservative and including the new genus in Acanthoderini, due to the current inclusion of Peritapnia in this tribe.

Wappesicus Santos-Silva & Nascimento, gen. nov.

Etymology. Latin, sufix “-icus” (belonging to), added to the surname of James E. Wappes. Masculine gender.

Type species. Wappesicus wappesi sp. nov., here designated.

Description, female. Body moderate-sized, flattened. Head not retractile; frons transverse, not forming transverse plate, slightly convex close to clypeus, V-shaped, centrally depressed toward vertex. Gena distinctly shorter than lower eye lobe. Eyes coarsely faceted; distance between upper eye lobes distinctly larger than twice width of one upper eye lobe. Outer side of mandibles with large triangular depression, with its apex surpassing middle of mandible. Last maxillary and labial palpomeres gradually narrowed toward apex. Antennal tubercles not forming plate laterally on scape ball. Antennae filiform, shorter than body; scape longer than antennomere III, slightly piriform, not reaching middle of prothorax; antennomeres III and IV subequal in shape and length. Prothorax transverse, with distinct, wide posterior constriction; sides strongly divergent from anterolateral angles to acute lateral tubercle, then strongly convergent toward base of posterior constriction. Procoxal cavities closed posteriorly. Prosternum slightly transversely sulcate near base of prosternal process. Prosternal process wide, with narrowest area slightly narrow than procoxal cavity, very slightly more elevated than surface of prosternum, strongly widened from middle toward apex, which is laterally lobe-shaped, and with posterior margin widely concave; posterior half inverted V-shaped depressed centrally. Mesoventral process wide, moderately narrowed centrally (narrowest area about as wide as procoxal cavity). Mesocoxal cavities closed, but with apex of mesoventrite distinctly not touching apex of metaventrite. Scutellum proportionally small, posteriorly rounded. Elytra slightly longer than 1.5 time humeral width; parallel-sided from humerus to slightly after middle, then gradually, round narrowed toward sutural angle. Femora fusiform. Abdominal ventrite V strongly inverted, V-shaped and centrally depressed, with distal margin of this area narrowly elevated (plate-shaped).

Remarks. Wappesicus gen. nov. is similar to Peritapnia but differs as follows: prosternal and mesoventral processes nearly as wide as the pro- and mesocoxal cavities (Fig. 21); scape more elongate, not distinctly piriform (Figs 19, 20); femora fusiform (Fig. 21). In Peritapnia, the prosternal and mesoventral processes are distinctly narrower than procoxal cavities (Figs 2, 7), scape distinctly piriform (Figs 4, 8), and the femora are pedunculate-clavate (Figs 2, 6). Wappesicus gen. nov. differs from Tapeina by the antennae (Fig. 20) shorter than body [longer (Fig. 18) in female of Tapeina], scape slightly piriform, not reaching middle of prothorax [cylindrical (Fig. 18), reaching middle of prothorax in Tapeina], and prothorax (Fig. 20) with acute lateral tubercle [rounded (Fig. 18) in Tapeina].

This species was originally described from Brazil (Goiás, Mato Grosso do Sul, Espírito Santo, São Paulo), Paraguay (Concepción), and Argentina (Salta, Formosa, Santiago del Estero). Di Iorio (2004Di Iorio, O. 2004: Aporte al catálogo de Cerambycidae del Paraguay (Insecta, Coleoptera). Parte IV. Addenda a Bosq (Partes I y II) y Viana (Parte III). Boletín del Museo Nacional de Historia Natural del Paraguay 15(1-2):9-65.) reported the species for the Paraguayan department of Alto Paraguay; Wappes et al. (2006Wappes, J. E.; Morris, R. F.; Nearns, E. H. & Thomas, M. C. 2006. Preliminary list of Bolivian Cerambycidae (Coleoptera). Insecta Mundi 20(1-2):1-45.) recorded the species in the Bolivian department of Santa Cruz; Wappes et al. (2013)Wappes, J. E.; Lingafelter, S. W.; Monné, M. A. & Arias, J. L. 2013. Additions to the known Vesperidae and Cerambycidae (Coleoptera) of Bolivia. Insecta Mundi 319:1-28. listed it in the Bolivian department of Tarija; and Martins et al. (2011Martins, U. R.; Galileo, M. H. M. & Limeira-de-Oliveira, F. 2011. Cerambycidae (Coleoptera) do Estado de Maranhão, Brasil III. Papéis Avulsos de Zoologia51(18):275-293.) recorded it in the Brazilian state of Maranhão. Originally, Marinoni (1972)Marinoni, R. C. 1972. Estudo monográfico do gênero Tapeina Lep. & Serv., 1828 (Coleoptera, Cerambycidae). Boletim da Universidade Federal do Paraná (Zoologia) 5(1):1-76. listed some paratypes as being from the Brazilian state of Mato Grosso, which was true at that time. However, currently, the places where those paratypes were collected are in the Brazilian state of Mato Grosso do Sul.

We are taking this opportunity to illustrate a paratype female (Fig. 17), and another female (Fig. 18) collected in Bolivia. Although Marinoni (1972) had drawings of females, only a frontal view photograph of the head of a female paratype has been published.

Material examined (only the specimen from Bolivia listed) BOLIVIA, Santa Cruz: Florida (Pampagrande), 1 female, 23.XI.1995, F. A. Langer col. (ACMT).
