Descriptions, notes and new records in south american Cerambycidae (Coleoptera)

ABSTRACT

Three new species and one new genus are described: Psyrassa lisitskyi sp. nov., from Peru (Elaphidiini); Ophtalmibidion antonkozlovi sp. nov., from Colombia (Neoibidionini); and Nappella gen. nov., is proposed to N. antonkozlovi sp. nov., from Peru (Calliini). Epectasis mexicana Breuning, 1954 is redescribed, and figured for the first time, and recorded for Colombia. Psyrassa lisitskyi is included in a modified couplet from a previous key. A key to species of Ophtalmibidion and genera of Calliini are provided. Chorenta biramiguelus is recorded for Peru.

INTRODUCTION

Central and South America have a great and complex geobiotic history which reflects in its great biodiversity (Carvalho & Almeida, 2011Carvalho, C.J.B. & Almeida, E.A.B. 2011. Biogeografia da América do Sul: padrões & processos. São Paulo, Roca., xii + 306p.). The immense diversity of Cerambycidae can be verified in the “Catalog of Cerambycidae (Coleoptera) of the Neotropical Region”, which includes distribution and taxonomic history of the species (Monné, 2018Monné, M.A. 2018a. Catalogue of the Cerambycidae (Coleoptera) of the Neotropical Region. Part I. Subfamily Cerambycinae. Available at: http://cerambyxcat.com. Access in: 10/2018.

Recently Anton Olegovich Kozlov (Moscow, Russia), sent several specimens of Cerambycidae, mostly from Mexico, Costa Rica, Peru, and Colombia for study in the MZSP. Through the study of these specimens we found some new species, which are described and illustrated, and establish a new country record. Additionally, we redescribed Epectasis mexicanaBreuning, 1954Breuning, S. 1954. Nouvelles formes de Lamiaires (Septième partie). Bulletin de l’Institut de Sciences Naturelles de Belgique, 30(41): 1-23. to provide detailed information for future revisions of this problematic genus with poorly defined species.

MATERIAL AND METHODS

Photographs were taken with a Canon EOS Rebel T3i DSLR camera, Canon MP-E 65 mm f/2.8 1-5X macro lens, controlled by Zerene Stacker AutoMontage software. Measurements were taken in “mm” using measuring ocular Hensoldt/Wetzlar - Mess 10 in the Leica MZ6 stereomicroscope, also used in the study of the specimens.

Only the new species of Psyrassa is described by the four authors. The new genus and the other new species are described by the three first authors. We redescribed Epectasis mexicana based on the holotype and in a second known male.

The acronyms used in the text are as follows:

  • AKPC = Anton Kozlov Private Collection, Moscow, Russia

  • MZSP = Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil

  • RBINS = Royal Belgian Institute of Natural Sciences, Brussels, Belgium

RESULTS

Cerambycinae laphidiini Thomson, 1864

syrassa Pascoe, 1866

Psyrassa was revised by Toledo (2005Toledo, V.H. 2005. Revisión taxonómica del género Psyrassa Pascoe (Coleoptera: Cerambycidae). Acta Zoológica Mexicana, 21(3): 1-64.). After this, seven species were described. Currently, the genus includes 42 species distributed from southern United States of America to northern South America, including Caribbean islands (Monné, 2018Monné, M.A. 2018c.

Martins (2005Martins, U.R. 2005. Elaphidionini Thomson, 1864, pp. 1-394. In: Martins, U.R. (Org.). Cerambycidae Sul-Americanos (Coleoptera). Taxonomia. São Paulo, Sociedade Brasileira de Entomologia. v. 7, ii + 394p.) characterized the South American species of Psyrassa by the prothorax longer than wide, with III antennomere as long as the IV and with an apical spine, blunt-tipped, almost as long as the antennomere, by the center of the pronotum without tubercles and by the sublinear metafemora. In his phylogenetic study, Lingafelter (1998Lingafelter, S.W. 1998. The genera of Elaphidiini Thomson 1864 (Coleoptera: Cerambycidae). Memoirs of the Entomological Society of Washington, 20: 1-118.) characterized the genus by the strong basal pronotal constriction, sparsely punctate, pubescent pronotum, procoxal cavities strongly closed and by the short antennomere III.

Etymology: The new species is named to honor Victor Nikitovich Lisitsky, a retired Soviet gymnast, who competed in all artistic gymnastics events in the 1964 and 1968 Summer Olympics, and won five silver medals, three individual in 1964 and two with the Soviet team, in 1964 and 1968. He is a personal friend of the fourth author, who chose the name of the species.

Remarks: Currently, six species of Psyrassa Pascoe, 1866 are known from South America (Monné, 2018Monné, M.A. 2005. Catalogue of the Cerambycidae (Coleoptera) of the Neotropical Region. Part II. Subfamily Lamiinae. Zootaxa, 1023: 1-759.a), none of them occurring in Peru: P. ludmilakozlovaeSantos-Silva et al., 2017Santos-Silva, A.; Botero, J.P. & Taboada-Verona, C. 2017. Three new species of Psyrassa Pascoe, 1866 (Coleoptera, Cerambycidae, Cerambycinae). Zootaxa, 4250(5): 494-500.; P. meridionalisMartins, 2005Martins, U.R. 2005. Elaphidionini Thomson, 1864, pp. 1-394. In: Martins, U.R. (Org.). Cerambycidae Sul-Americanos (Coleoptera). Taxonomia. São Paulo, Sociedade Brasileira de Entomologia. v. 7, ii + 394p.; P. rufescens Nonfried, 1894; P. subglabra Linsley, 1935; P. testacea Linsley, 1935; and P. unisucre Santos-Silva et al., 2017. Psyrassa lisitskyi sp. nov., differs from P. ludmilakozlovae by the spine of inner apex of the antennomere III straight and distinctly shorter than maximum width of the antennomere, antennomere IV with minute spine at inner apex, antennomeres V-VII unarmed at inner apex, procoxal cavities open posteriorly, and outer elytral apex without spine. In P. ludmilakozlovae, the spine of inner apex of the antennomere III is curved and distinctly longer than maximum width of the antennomere, antennomere IV has long spine at inner apex, antennomeres V-VII have distinct spine at inner apex, procoxal cavities are closed posteriorly, and the outer elytral apex has distinct spine. It differs from P. meridionalis by the spine of antennomere III distinctly shorter (longer than maximum width of the antennomere in P. meridionalis), apex of antennomere IV with spicule (with distinct spine in P. meridionalis), and procoxal cavities open posteriorly (closed in P. meridionalis). According to Martins (2005), Toledo (2005Toledo, V.H. 2005. Revisión taxonómica del género Psyrassa Pascoe (Coleoptera: Cerambycidae). Acta Zoológica Mexicana, 21(3): 1-64.), and Santos-Silva et al. (2017), P. rufescens evidently does not belong to Psyrassa, especially by the prothorax “obtuse spinosis” laterally, and “quinquegibbosus” dorsally. Unfortunately, the holotype may be lost forever (Martins, 2005). Psyrassa lisitskyi differs from P. subglabra by the color of the pronotum not notably contrasting to that of the elytra (contrasting in P. subglabra), antennomere IV with spicule at apex (with distinct spine in P. subglabra), and elytral apex without spine (with long outer spine in P. subglabra). The new species differs from P. testacea by the spine of antennomere III distinctly shorter than maximum width of the antennomere (distinctly longer in P. testacea), antennomere IV with spicule at apex (with distinct spine in P. testacea), antennomere V unarmed at apex (with spine in P. testacea), pronotum without long and erect setae (present in P. testacea), and procoxal cavities open posteriorly (closed in P. testacea). Psyrassa lisitskyi differs from P. unisucre by the spine of antennomere III distinctly shorter than maximum width of the antennomere (noticeably longer in P. unisucre), antennomere IV with spicule at apex (with long spine in P. unisucre), antennomeres V-VII unarmed at apex (with distinct spine in P. unisucre), procoxal cavities open posteriorly (closed in P. unisucre), and elytral apex not bispinose (bispinose in P. unisucre).

Psyrassa lisitskyi can be included in the alternative of couplet “19” from Toledo (2005Toledo, V.H. 2005. Revisión taxonómica del género Psyrassa Pascoe (Coleoptera: Cerambycidae). Acta Zoológica Mexicana, 21(3): 1-64. ) (translated):

Nappella Santos-Silva, Nascimento & Drumont, gen. nov.

Type species: Nappella antonkozlovi new species, current designation.

Etymology: Surname of the late Dr. Dilma Solange Napp + “- ella”, Latin, used to form a diminutive, indicating small size. Feminine gender.

Description: Frons transverse. Eyes coarsely faceted; lower eye lobes about 3.5 times genal length; distance between upper eye lobes shorter than maximum width of one upper eye lobe. Scape without apical cicatrix; slightly, gradually widened toward apex, shorter than antennomere III. Antennomeres filiform, cylindrical (III-VI cylindrical, slightly widened toward apex), without long and dense setae ventrally; antennomere III slightly longer than IV. Prothorax transverse, with small, acute tubercle laterally, placed at about midlength. Pronotum with three slightly conspicuous gibbosities. Prosternal process notably narrow centrally. Mesoventral process not tuberculate. Elytra convex, without carinae, not depressed along suture, parallel-sided, pubescent; humerus rounded; elytral length about 2.5 times humeral width; apex nearly rounded; with erect setae throughout. Femora slightly clavate, profemora less so; apex of metafemora reaching about middle of ventrite III. Mesotibiae not notched dorsally. Metatarsomere I slightly longer than II-III together.

Remarks: The general appearance of Nappella gen. nov., resembles that of Colombicallia Galileo & Martins, 1992, Graminea Thomson, 1864, Callia Audinet-Serville, 1835, Callisema Martins & Galileo, 1990, Drycothaea Bates, 1881, Eumathes Thomson, 1868, and Hirticallia Galileo & Martins, 1990. Nappella differs from Callisema, Drycothaea, and Eumathes by the mesoventral process lacking a tubercle (tuberculate in these three genera). It differs from Graminea by the scape lacking an apical cicatrix (present in Graminea). The new genus can be separated from Callia especially by having the eyes coarsely faceted (finely faceted in Callia). It can be separated from Hirticallia, which also has eyes coarsely faceted, by the slender body, with elytral length about 2.5 times humeral width (body stouter, with elytral length about 2.0 times humeral width in Hirticallia), prothoracic lateral tubercle short and not spiniform (long and spiniform in Hirticallia), and elytra with short erect setae (distinctly long in Hirticallia). Finally, Nappella differs from Colombicallia by the slender body (wider in Colombicallia), distance between upper eye lobes smaller than half of the width of one upper lobe (from equal to larger in Colombicallia), prosternal process notably narrow (about ⅓ of procoxal cavity in Colombicallia), and mesoventral process narrower than half of width of mesocoxal cavity (wider than half of mesocoxal cavity in Colombicallia).

Pteropliini Thomson, 1860

Epectasis Bates, 1866

Epectasis was originally described in Pogonocherini for E. attenuata Bates, 1866 (= Saperda juncea Newman, 1840), from Brazil (Amazonas). 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. Paris, Librairie Encyclopédique de Roret, v. 9, pt. 2, p. 411-930.) transferred Epectasis to Estolini, currently a junior synonym of Desmiphorini. Bates (1880) included Epectasis in Ataxiini (currently, equal to Pteropliini): “I propose to include it in the “groupe” Ptéropliides of the ‘Genera,’ and the genera Epectasis, Amphicnaeia, and Aletretia, which have been hitherto placed in widely different groups.” Aurivillius (1923Aurivillius, C. 1923. Coleopterorum Catalogus, pars 74, Cerambycidae: Lamiinae. Berlin, W. Junk. p. 323-704.) included Epectasis in Emphytoeciini, currently under synonymy of Pteropliini. Epectasis remains a problematic genus, with evident different species often being identified as a single species. This is notably true regarding E. juncea. It is possible to note in Bezark (2018Bezark, L.G. 2018. A photographic Catalog of the Cerambycidae of the New World. Available at: Available at: https://apps2.cdfa.ca.gov/publicApps/plant/bycidDB/wsearch.asp?w=n . Access in: 10/2018.
https://apps2.cdfa.ca.gov/publicApps/pla...
) that some species with remarkable differences are being identified as E. juncea. However, it is not the scope of this work to deal with these problems in Epectasis, a genus needing a full revision.

Area behind upper eye lobes with light-brown pubescence obscuring integument; with a few long, erect yellowish setae close to eye. Area behind lower eye lobes finely punctate; with light-brown pubescence nearly obscuring integument; with long, erect, sparse light-brown setae close to eye. Scape finely punctate with its maximum length at middle of its length, and then slightly curved internally to form at external apex rounded tooth; sides nearly parallel-sided toward apex and after first basal third. Antennomere III with dense light-brown pubescence basally, sparser, light-brown on remaining dorsal surface; with sparse light-brown setae around surface except on internal side where setae become longer and more numerous. Remaining antennomeres slenderer, with less setae when progressing to apex of antenna; basal part covered with rather dense whitish pubescence forming ring extending on <mml:math><mml:mfrac><mml:mn>1</mml:mn><mml:mn>5</mml:mn></mml:mfrac></mml:math> of length of segment. Antennomere IV little bit longer than II+III combined and shorter than V+VI, length of segment V equal to VI.

Thorax: Prothorax little bit longer than wide (including lateral tubercles); sides with small, distinct conical tubercle at middle with top directed to posterior part of body. Pronotum finely, densely punctate; with no well-defined elevation on dorsal surface occupying ⅔ of anterior central part of pronotum; this elevation is excavated in its basal central part Y-shaped, but with very large base; covered with long light-brown pubescence obscuring integument from which emerge some sparse erect yellowish setae; same pubescence present on area before this elevation, along median line of pronotum and along posterior margin of dorsal part of pronotum; remaining surface covered with sparse and short light-brown pubescence not obscuring integument. Sides of prothorax very finely punctate; with two no well defined longitudinal lines of very light-brown pubescence covering integument; between those lines, on ventral side and on prosternal process, covered with sparse, short light-brown pubescence not obscuring integument; with some sparse erect yellowish setae. Elytra: Slightly, gradually narrowed from humerus at basal third, nearly parallel-sided at central third, slightly curved at posterior third; apex obliquely truncate; with surface punctate on first half of elytra, with sparse and deep punctures somewhat organized in rows, which are separate from each other by space larger than diameter of punctures, covered with very fine puncture; this string puncture tends to become smaller and sparser after ⅔ of length of elytra; surface also with some no well defined longitudinal yellowish-white pubescent bands on basal half, except along suture with yellowish, gradually whiter pubescence along suture; area between yellowish-brown pubescent bands on basal half with brownish pubescence not obscuring integument; posterior half with irregular white pubescence not obscuring integument, with some erect, long, sparse white and brown setae; apex of elytra with dense fringe of curved light-brown setae. Legs: Coxae with sparse yellowish-brown pubescence not obscuring integument, with long, erect light-brown setae. Femora with yellowish-brown pubescence not obscuring integument, sparser on profemora, with short, decumbent white setae interspersed (more abundant on profemora); all femora with long, erect, moderately sparse uniformly golden-yellowish setae. Protibia with yellowish-brown pubescence basally, brownish on remaining surface; with both, short and long white setae interspersed (long setae dark basally). Meso- and metatibiae with yellowish-brown pubescence basally and distally (bristly distally), sparser, brownish, with decumbent white setae interspersed on central area.

Abdomen: Ventrites finely punctate; with light-golden pubescence nearly obscuring integument; with moderately long, yellowish white setae; some of these setae becoming slenderer, longer and oriented at 45° on ventrite V, emarginate centrally.

Dimensions (mm): Total length, 12.00; prothorax: length, 1.90; anterior width, 1.55; posterior width, 1.60; maximum width, 1.85; humeral width, 2.30; elytral length, 9.40. Total length of the holotype, 10.5 mm.

Material examined: MEXICO, holotype male (RBINS; former Lacordaire collection). COLOMBIA (New country record), Norte de Santander: Road 70 (2,250 m; near Alto El Pozo; 08°02’19”N, 73°02’13”W), 1 male, 21-24.VII.2017, V. Sinyaev col. (MZSP, former AKPC).

Remarks: Epectasis mexicana differs from E. juncea (Newman, 1840), E. attenuata Bates, 1866, and E. grossepunctata Breuning, 1942, especially by the elytra 3.4 times longer than head + prothorax. In the holotype of E. juncea, the elytra are about 2.8 times as long as head + prothorax; about 2.7 times in the holotype of E. attenuata Bates, 1866; and about 2.65 times in the holotype of E. grossepunctata Breuning, 1942. Additionally, the lateral tubercles of the prothorax are well-marked and conical in E. mexicana, while they are slightly marked and rounded in E. juncea.

Variations (Figs. 13-15) and additional features not studied in the holotype: Body somewhat wider in the holotype. Antennomeres IV-X with basal yellowish-brown ring, gradually reddish brown toward dark brown distal area (short on IV, reaching about midlength on remaining antennomeres).

This species was described and remains known only from Brazil (Rondônia and Mato Grosso). Monné & Hovore (2006Monné, M.A. 2006. Catalogue of the Cerambycidae (Coleoptera) of the Neotropical Region. Part III. Subfamilies Parandrinae, Prioninae, Anoplodermatinae, Aseminae, Spondylidinae, Lepturinae, Oxypeltinae, and addenda to the Cerambycinae and Lamiinae. Zootaxa, 1212: 1-244.) recorded: “Brasil (MG, RO).” Evidently, the state of Mato Grosso was incorrectly abbreviated as being “MG”. Actually, the abbreviation of Mato Grosso is “MT”, while “MG” means Minas Gerais. Dalens et al. (2010Dalens, P.-H.; Touroult, J. & Tavakilian, G.L. 2010. Un nouveau prionien du plateau des Guyanes (Coleoptera, Cerambycidae, Prioninae). L’Entomologiste, 66(4): 181-185.), apparently following Monné & Hovore (2006Monné, M.A. & Hovore, F.T. 2006. A Checklist of the Cerambycidae, or longhorned wood-boring beetles, of the Western Hemisphere. California, Bio Quip Publications. 394p.), also incorrectly recorded “Brésil (Minas Gerais, Rondônia).”

Recently we examined two specimens from Peru that belong to this species (new country record).

Material examined: PERU, Loreto: Allpahuayo-Mishana National Reserve (Iquitos-Nauta road, km 28), 2 females, XI.2017, E.L. Rojas col. (AKPC).
