Toma, Ronaldo, 2019, Five new species in the genus Leschenaultia Robineau-Desvoidy, 1830 (Diptera: Tachinidae) from Mato Grosso, Mato Grosso do Sul and Rondônia, Brazil, Zootaxa 4577 (1), pp. 103-116 : 113

Leschenaultia liriai sp. n.

( Figs 12 , 18 )

Recognition. The abdominal chaetotaxy of this species is as in L. belkysae sp. n. and L. frangeri sp. n., but it differs from both these species by the more curved and narrower cercus in profile. Leschenaultia liriai sp. n. resembles L. brooksi and L. braueri but differs from the former by the narrower and more curved cercus in profile, and from the latter by fore claws longer than second fore tarsomere and longer and narrower cercus in profile.

Description. Male. Body length: 11.55–12.64 mm; wing length: 11.51–11.85 mm.

Coloration. Vertex, frontal vitta, ocellar triangle, fronto-orbital plate and apical third of parafacial dark brown; the rest of head lighter; head with gray pruinosity; antenna dark brown, except portion between first flagellomere and pedicel and apex of scape yellowish; palpus yellow, basal portion in the paratype darker; proboscis dark brown; thorax dark brown, except for suture between katepisternum and meron and anterior portion of postalar callus yellowish or brown and for anepimeron, katatergite and anatergite brown; thorax with gray pruinosity; scutum in posterodorsal view with four visible stripes, two outside of the dorsocentral rows (presutural stripes triangular) and two outside of the acrostichal rows, not reaching posterior margin of scutum, all stripes are narrower than in L. andarae sp. n.; halter yellowish; wing and abdomen as in L. andarae sp. n.

Head. Vertex about 0.25x head width in dorsal view; ocellar, reclinate orbital and inner vertical setae missing, remaining their sockets (in both specimens); fronto-orbital plate with 10–13 frontal setae, one or two setae situated below level of lower margin of pedicel, upper frontal seta shorter and thinner, and with a few smaller adjacent setae; first flagellomere about 2.2x length of pedicel; facial ridge with a row of supravibrissal setae on lower 0.6 of its length, setae 0.24–0.37x length of vibrissa.

Thorax. Posteriormost postsutural dorsocentral seta about twice length of preceding seta; posteriormost postsutural intra-alar setae about 1,7x length of preceding seta; second and third postsutural supra-alar setae equal in length and about twice length of first postsutural supra-alar seta; mid tibia with three to four strong anterodorsal setae, the longest about one-half length of tibia and about twice length of anteroventral seta.

Abdomen. Syntergite 1+2 and tergite 3 with a few very short median marginal setae hardly distinguishable from ground setulae; tergite 4 with a row of strong median marginal setae; tergites 3 and 4 without discal setae; tergite 5 with many discal setae, weaker than median marginal setae on tergite 4. Terminalia ( Figs 12 , 18 ). Cercus in profile tapering to apex, anteriorly gently curved backward, curvature slightly more accentuated in apical third; cercus posteriorly almost straight to apical third, then smoothly bending backward; surstylus in profile with rounded or slightly subtriangular apex and about 0.8x length of cercus.

Female. Unknown.

Geographic distribution. Brazil (Rondônia).

Type material. HOLOTYPE ♂ ( MZUSP), labeled: “ BRASIL: RO: Porto Velho / AHE Jirau—Rio Madeira / S9°26’8.2” W 64°48’9.5” / Malaise 7° Camp. T2 e T4 / 18–29.vi.2011 / E. Z. Albuquerque & L. S. Ferreira cols.”; “ Leschenaultia liriai / Holotype [red label, species name handwritten]”. [Holotype in good condition, except for missing left foreleg and some missing head and thoracic setae, and for damaged right surstylus.]

PARATYPE. 1 ♂ ( MZUSP), labeled: “ BRASIL: RO: Porto Velho / Rio Madeira—Área Abunã / AHE Jirau (11° campanha) / Transectos A10–A12 / Margem direita / S09°35’53.1” W 65°22’00.1” / Malaise / 17.vi– 01.vii.2012 / Sanhudo, C.E.D. & Andriolli, F. cols.”; “ Leschenaultia liriai / Paratype [red label, species name handwritten]”. [In good condition except for some missing head and thoracic setae.]

Etymology. The specific epithet is in honor of Jonathan Liria, a colleague from the biology department at Universidad de Carabobo, Venezuela.
