Introduction

A new genus and species of Tachinidae, Paxiximyia sulmatogrossensis n. gen. and n. sp., reared from adult Urucumania borellii (Giglio-Tos, 1897Giglio-Tos, E., 1897. Viaggio del dott. Alfredo Borelli nel Chaco Boliviano e nella Republica Argentina. X. Ortotteri. Bolletino dei Musei di Zoologia e Anatomia Comparata dell’Università di Torino 12, 1-47.) (Pseudophasmatidae), is described in this paper. According to Guimarães (1977Guimarães, J.H., 1977. Host-parasite and parasite-host catalogue of South American Tachinidae (Diptera). Arq. Zool. 28, 1-131., 1978Guimarães, J.H., 1978. Note on Neotropical Oedematocerini, with a new genus and species from Brazil (Diptera, Tachinidae). Pap.

Taquínidos chilenos (Dipt., Tachinidae) parásitos de Phásmidos (Phasmoidea). Bol. Soc. Bio. de Concepc. 15, 101-111., a few Tachinidae genera are known as parasitoids of Phasmatodea and Orthoptera in the Neotropical Region, most of them belonging to the Acemyini, Ormiini, and Blondeliini tribes. Most Acemyini are parasitoids of Acrididae. Members of Ormiini have been reared from Gryllidae and Tettigoniidade. Most species of Blondeliini have been recorded parasitizing either larvae and adults of Coleoptera and larvae of Lepidoptera, while a few have been documented parasitizing sawflies, crane flies, and wasp larvae, as well as immature and adult Blattodea, Phasmatodea, and Orthoptera (Wood, 1985Wood, D.M., 1985.

The Oedematocera genus group, as treated here, corresponds mostly with the former tribe Oedematocerini, which included the following New World genera: Miamimyia Townsend, 1916, Miamimyiops Townsend, 1939, NeophasmophagaGuimarães, 1982Guimarães, J.H., 1982.

Three new Oedematocerini from Brazil (Diptera, Tachindae). Rev. Bras. Entomol. 26, 213-217.). Most of these genera parasitize Polyneoptera (Guimarães, 1971Guimarães, 1971 Guimarães, J.H., 1971.

Three new Oedematocerini from Brazil (Diptera, Tachindae). Rev. Bras. Entomol. 26, 213-217.). Currently they are placed in the Blondeliini tribe and many are synonyms of Phasmophaga Townsend, 1909 (= Phasmovora) or Anisia Wulp, 1890 (= Nepophasmophaga , Oedematocera, Tamanamyia) (Wood, 1985Wood, D.M., 1985.

Paxiximyia n. gen. resembles genera in this group. According to Wood (1985)Wood, D.M., 1985. A taxonomic conspectus of the Blondeliini of North and Central America and the West Indies (Diptera, Tachinidae). Mem. Entomol. Soc. Can. 132, 1-130., Oedematocera-group, including Meigenielloides Townsend, 1919, external morphology and host preference suggest its genera may be related.

The new genus belongs to Blondeliini, with which it shares the following combination of characteristics mentioned by Wood (1985)Wood, D.M., 1985. A taxonomic conspectus of the Blondeliini of North and Central America and the West Indies (Diptera, Tachinidae). Mem. Entomol. Soc. Can. 132, 1-130. in his conspectus of the Blondeliini of North and Central America and West Indies: prosternum setose, first postsutural supra-alar seta smaller than first postsutural dorsocentral seta, bend of vein M rounded, subapical scutellar setae long and divergent, vein R 4+5 ending at or near wing tip, body elongated, and mid-dorsal depression of abdominal syntergite 1 + 2 not reaching hind margin.

Material and methods

Host collection

Four male and three female adult U. borellii specimens were collected in Morro do Paxixi, Aquidauana, Mato Grosso do Sul, Brazil (20º27'00.5"S/55º37'20.8"W) on January 19, 2017. The collection was carried out with permission from the Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio authorization number 49550-1).

Specimen measurements, description, and deposit in collections

Morphological terminology of structures follows McAlpine (1981)McAlpine, J.F., 1981. Morphology and terminology – adults.

Head structures were measured according to Toma and Guimarães (2002)Toma, R., Guimarães, J.H., 2002. Estudo taxonômico de Leschenaultia Robineau–Desvoidy (Diptera, Tachinidae). Rev. Bras. Entomol. 46, 33-70.. Images of body structures and measurements of tachinid flies were taken under a Leica M205C stereomicroscope with a coupled Leica DFC420 camera, and analyzed using Leica Application Suite V. 3.8.0 imaging software. Images and measurements of the hosts and puparium were taken under a Zeiss Discovery V20 stereomicroscope with a coupled Zeiss AxioCam ICc5 camera, using AxioCam IC-ZEN pro 2012 software.

Paxiximyia sulmatogrossensisn. gen. and n. sp. type specimens were deposited in the Coleção Zoológica de Referência at the Universidade Federal de Mato Grosso do Sul (ZUFMS) in Campo Grande and the Diptera Collection at the Museu de Zoologia da Universidade de São Paulo (MZUSP) in São Paulo. All U. borellii specimens were deposited with ZUFMS.

Recognition. In the Central American key to Tachinidae (Wood and Zumbado, 2010Wood, D.M., Zumbado, M., 2010. Tachinidae. In: Brown, B.V., Borkent, A., Cumming, J.M., Wood, D.M., Woodley, N.E., Zumbado, M.A.(Eds.), Manual of Central American Diptera, vol.2. NRC Research Press, Ottawa, pp. 1343–1417.), the specimens P. sulmatogrosensis n. sp. run to Blondeliini with haired prosternum in couplets 115–119, but do not fit into any these specific couplets. In Wood's (1985)Wood, D.M., 1985. A taxonomic conspectus of the Blondeliini of North and Central America and the West Indies (Diptera, Tachinidae). Mem. Entomol. Soc. Can. 132, 1-130. key, the specimens run to Meigenielloides Townsend, 1919, but Paxiximyia n. gen. differs from this genus in having distinctly longer anteriormost reclinate orbital setae than uppermost frontal setae and vein R 4+5 being setose almost to crossvein r-m.

Within the Oedematocera -group, Paxiximyia n. gen. appears similar to Neophasmophaga and Miamimyia because both veins R 1 and R 4+5 are dorsally setulose on at least the basal third. The new genus is distinguished from these two genera by lack of proclinate orbital setae on fronto-orbital plate, facial ridge with a few setae on lower third above vibrissa, and a pair of abdominal discal setae on tergites 3 and 4. Male Paxiximyia n. gen. genitalia is distinctive with inner cerci surface deeply excavated and haired and surstyli elongated and narrow, precluding its consideration as congeneric with Neophasmophaga and Miamimyia species or species pertaining to other Oedematocera -group genera with known genitalia morphologies.

Paxiximyian. gen. differs from Anisia and Phasmophaga by katepisternum with three setae and mid tibia with two anterodorsal setae. According to Wood (1985)Wood, D.M., 1985. A taxonomic conspectus of the Blondeliini of North and Central America and the West Indies (Diptera, Tachinidae). Mem. Entomol. Soc. Can. 132, 1-130., TettigoniophagaGuimarães, 1978Guimarães, J.H., 1978. Note on Neotropical Oedematocerini, with a new genus and species from Brazil (Diptera, Tachinidae). Pap. Avulsos Zool. 31, 299-305. appears to belong to Anisia. He suggested that the absence of proclinate orbital setae and narrow frons in the male would not be enough to separate them. Wood (op. cit.) included Tettigoniophaga in the range of variation presented by Anisia species, but he did not formalize the synonymy. Paxiximyia n. gen. can be differentiated from Tettigoniophaga in the same manner as Anisia. The new genus differs from Miamimyiops in proclinate orbital setae absent on fronto-orbital plate, facial ridge with a few setae on lower third above vibrissa, a pair of median marginal setae on syntergite 1 + 2 and tergite 3, and a pair of median discal setae on tergites 3 and 4.

Description. Characteristics follow Wood (1985)Wood, D.M., 1985. A taxonomic conspectus of the Blondeliini of North and Central America and the West Indies (Diptera, Tachinidae). Mem. Entomol. Soc. Can. 132, 1-130.. Head (Figs. 13): Fronto-orbital plate without proclinate orbital setae and with two reclinate orbital setae, anteriormost reclinate orbital seta distinctly longer than posteriormost reclinate orbital seta and uppermost frontal seta; ocellar setae long and divergent; eye bare; parafacial bare; lower margin of face at level of vibrissa not visible in profile; arista longer than first flagellomere; facial ridge with a few setae on lower third above vibrissa; subvibrissal ridge short with two or three setae; anteroventral margin of gena bearing at least three stout setae. Thorax ( Figs. 1, 3, 4): prosternum with a few fine setulae; proepisternum bare; postpronotum with three basal and one short anterior setae, middle basal seta displaced slightly forward in line with outer basal and anterior setae; katepisternum with three setae, anteroventral seta shorter and weaker than anterior and posterior setae; scutellum with one pair each of basal, lateral, subapical, apical, and discal setae, lateral setae subparallel and shorter than basal and subapical setae, the latter ones slightly divergent, apical setae very short, setula-like and subparallel; fore tibia with two posterior setae; mid tibia with two anterodorsal setae; dorsally vein R1 setose on basal half and vein R4+5 setose almost to crossvein r-m; ventrally one to three setulae at bifurcation of veins R2+3 and R4+5; veins R4+5 and M both ending before wing apex. Abdomen (Fig. 3): middorsal depression not reaching hind margin of syntergite 1 + 2; abdominal syntergite 1 + 2 and tergite 3 each with one pair of well-developed median marginal setae and one pair of lateral marginal setae; tergite 4 with a row of median marginal setae; tergites 3 and 4 each with one pair of median discal setae. Terminalia (Figs. 5 and 6): Epiphallus developed; cerci with deeply excavated and haired inner surface, well separated almost along entire length and fused basally in posterior view; surstyli elongated and narrow.

Etymology. The root of the compound name Paxiximyia refers to the locality where the hosts of this tachinid fly were collected (“Morro do Paxixi”). The suffix “myia” is the Greek word for fly.

Remarks. In the New World, there are some records of Polyneoptera parasitism by genera in the Oedematocera genus group. Phasmophaga has been reared from Agathemera crassa (Blanchard, 1851) and Anisomorpha buprestoides (Stoll, 1813) (Phasmatodea: Agathemeridae and Pseudophasmatidae) (Neff and Eisner, 1960Neff, S.E., Eisner, T., 1960.

Taquínidos chilenos (Dipt., Tachinidae) parásitos de Phásmidos (Phasmoidea). Bol. Soc. Bio. de Concepc. 15, 101-111.). Anisia has been reared from Schistocerca americana (Drury, 1770), S. paranensis (Burmeister, 1861), Romalea microptera (Beauvois, 1817), and Ceuthophilus latibuli Scudder, 1894 (Orthoptera: Acrididae, Romaleidae and Gryllidae) (Aldrich, 1927Aldrich, J.M., 1927.

Agraria Filippo Silvestri, Portici. 12, 45-73.). Tettigoniophaga is known as parasitoid of Cycloptera aurantifolia (Stoll, 1787) (Orthoptera: Tettigoniidae) (Guimarães, 1978Guimarães, J.H., 1978. Note on Neotropical Oedematocerini, with a new genus and species from Brazil (Diptera, Tachinidae). Pap. Avulsos Zool. 31, 299-305.). Miamimyiops hosts are unknown, while Miamimyia and Neophasmophaga are documented as parasitoids of the coackroach, Periplaneta americana (Linnaeus, 1758) (Blattodea: Blattidae), and the walking stick, Prisopus sacratus (Olivier, 1792) (Phasmatodea: Prisopodidae), respectively (Arnaud, 1978Arnaud, P.H., 1978.

Three new Oedematocerini from Brazil (Diptera, Tachindae). Rev. Bras. Entomol. 26, 213-217.). The new taxon described here, P. sulmatogrossensis n. gen. and n. sp., reared from U. borellii, is the first record of parasitism in this host by a tachinid fly.

Measurements of type specimens. Type specimens withered after mounting and only one specimen preserved its body length, which was used in the description. The other measurements (mm) after the drying were (n = 4): body length: 7.77–8.09 (7.89); wing length: 6.44–7.05 (6.67).

Description of puparium (Figs. 7 and 8): Measurements of puparia (n = 2): Puparium I. length = 7.23 mm, width = 3.02 mm; Puparium II. length = 7.30 mm, width = 2.87 mm. Puparium reddish brown; subelliptical with both ends rounded; posterior spiracles narrowly separated, only slightly raised above the surface, located above horizontal axis, color dark brown except for three reddish brown slits, each one located on top of a small ridge. Anal opening far below posterior spiracles.

Etymology. The specific epithet refers to the Brazilian state in which the host was collected.

Geographic distribution. Brazil (Mato Grosso do Sul: Aquidauana) (Fig. 9).

Remarks. Emergence and viability of the tachinid larvae: five larvae emerged from an aperture (length = 7.40 mm) between second and third abdominal pleurites on the left side of the body (length = 75.00 mm) of a female host (Fig. 10) (ZUFMSPHA00001), three on January 20 and two on January 21, 2017. All larvae from the female host became adult flies. Three larvae emerged from an aperture (length = 3.70 mm) in the first abdominal pleurite on the right side of body (length = 64.00 mm) (Fig. 2) of a male host (Fig. 11) (ZUFMSPHA00002) on January 24, 2017, but only one became an adult fly. Development time from emergence of larvae to emergence of adult flies was 14–15 days.

Geographical distribution of the host.Urucumania borellii was described from Paraguay in 1897 by Giglio-Tos and all records before the present study were from Assunción, San Pedro, San Bernardino, and Puerto Bertoni in that country and Cuiabá in the state of Mato Grosso, Brazil. This paper presents new records from Brazil of specimens collected and/or photographed in the following cities: Aquidauana, Campo Grande, Bodoquena (Cordeiro, L., pers. comm., April 2017) (Fig. 9). The records obtained for this walking stick species are mainly from Cerrado phytophysiognomies, such as “cerradão”, but also from riparian forests and transitions between plateau (Cerrado) and lowlands (Pantanal), for example in Aquidauana. Probably U. borellii is widely distributed in the Cerrado domain, which would potentially increase the geographic distribution of P. sulmatogrossensis n. gen. and n. sp.
