Araújo, Maíra Xavier & Bravo, Freddy, 2012, Taxonomy of Neotropical Trichomyia (Septemtrichomyia) Bravo (Diptera, Psychodidae, Trichomyiinae) with descriptions of five new species, Zootaxa 3547, pp. 24-34 : 30-31

Trichomyia jezeki Araújo & Bravo sp. nov.

( Figs. 19–26 )

Diagnosis. Posterior arm of gonocoxite with apex digitiform, without rod-like setae on the margin. Gonostylus shorter than posterior arm of gonocoxite, with apex curved upward. Presence of one pair of sclerotized parameres, digitiform and apically divergent, 0.5 times the length of ejaculatory apodeme.

Description. Male. Head subcircular. Antenna incomplete in the specimens studied; scape subcylindrical, pedicel subspherical; basal flagellomeres pyriform and slightly eccentric ( Fig. 19 ); ascoids observed in only one paratype; S-shaped 1.3 times the length of flagellomere. Palpus formula 1.0:0.8:0.9. ( Fig. 20 ). Wing ( Fig. 22 ): Sc complete; R5 incomplete at base, not reaching R2+3+4; M2 with unsclerotized base; base of M3 not reaching CuA1, r-m and m-cu absent. Elongate bristles of tergum 7 with curved apices ( Fig.21 ). Male terminalia: Hypandrium and gonocoxites fused ( Fig. 25 ). Posterior arm of gonocoxite slender apically, digitiform, without rod-like setae on the internal margin ( Fig. 25 ). Gonostylus shorter than posterior arm of gonocoxite, apex curved upward ( Fig. 25 ). One pair of sclerotized parameres present, apically bifurcated, articulated to a subrectangular basal plate ( Figs. 23, 25, 26 ). Aedeagus subtriangular ( Figs. 25, 26 ). Ejaculatory apodeme long, 2.5 times the length of the gonostylus ( Figs.

25, 26). Epandrium wider than long ( Fig. 24 ); cercus subtriangular in ventral view ( Fig. 24 ). Hypropoct with apex truncate and with apical micropilosity ( Fig. 24 ).

Material examined. Holotype 3, BRAZIL, state of Pará, N. [Novo] Repartimento, Vic. [Vicente] Bandeirante, Sítio Pedro Roqueta, 19. VIII.1998, without name of collector ( MZFS); 3 paratypes: 1 3, same locality and data as holotype ( MZFS); 1 3, state of Amazonas, Pitinga, R.[Rua] dos Paturis, 0 2–04.VI.1998, without name of collector ( INPA); 1 3, Manaus, INPA, 0 8–12.II.2008, H.F. Mendes leg. ( INPA).

Distribution. Known from Novo Repartimento in Pará, Brazil, Pitinga and Manaus in Amazonas, Brazil.

Etymology. Named in honor of Dr. Jan Ježek of the National Museum in Prague, the Czech Republic, in recognition of his contribution to psychodid systematics.

Comments. T. jezeki sp. nov. shows some similarities to T. botosaneanui and T. satterlmairi in the shapes of their gonocoxites and gonostylus, but the parameres are differently shaped. Additionally, the new species can be confused with T. dolichakis . The differences are subtle at the apices of the parameres, which are wide and rounded in T. dolichakis and thinner and pointy in T. jezeki , in addition to the ejaculatory apodeme that is longer in the new species.
