Trichomyia menezesi sp. nov.

( Figure 5 View Figure 5 (a–i))

Diagnosis

Elongate bristles on tergum VII with straight apices. Gonocoxite posterior arm with apex wide, apically pilose with row of eight small, rod-like setae. One pair of lanciform parameres present, curved and sclerotised. Ejaculatory apodeme of the same length as the gonostylus.

Description

Adult male. Head subcircular ( Figure 5 View Figure 5 (a)). Antenna incomplete in studied specimens; scape longer than pedicel; scape subcylindrical and pedicel subspherical; basal flagellomeres pyriform and eccentric; ascoids lost in the specimen studied ( Figure 5 View Figure 5 (e)). Palpus three-segmented; first segment with sensilla in depressed pit on inner side; palpus formula 1.0:0.4:0.6 ( Figure 5 View Figure 5 (c)). Wing ( Figure 5 View Figure 5 (b)): Sc complete; R4 + 5 complete at base; r-m and m-cu absent. Elongate bristles on tergum VII with straight apices, lost in holotype ( Figure 5 View Figure 5 (h,i)). Male terminalia: Hypandrium fused with gonocoxite. Gonocoxite with posterior arm curved to the midline, apex wide, apically pilose with row of eight small, rod-like setae. Gonostylus digitiform with rounded apex. One pair of parameres, in dorsal view lanciform, curved and sclerotised. Aedeagus bifid and convergent. Ejaculatory apodeme of the same length as the gonostylus ( Figure 5 View Figure 5 (g)). Epandrium pilose, longer than wide, trapezoidal ( Figure 5 View Figure 5 (f)). Cercus pilose, droplet shaped in ventral view, dorsolaterally with row of long bristles ( Figure 5 View Figure 5 (d)). Hypoproct with rounded apex and apical micropilosity ( Figure 5 View Figure 5 (f)).

Material examined

Holotype ♂, BRAZIL, Espírito Santo, Aracruz (Reserva Biológica Aricanga), 9–11 January 2008, G. R. Leite leg. ( MZFS); 2 paratypes ♂, same locality, date and collector as holotype ( MZFS).

Distribution

Brazil (Espírito Santo).

Etymology

In honour of Eliomar da Cruz Menezes for his help in this study and collecting Psychodidae .

Remarks

Trichomyia menezesi is similar to T. cauga Bravo, 1999 and T. amazonensis in possessing a wide cercus and a row of rod-like setae on the gonostylus. However, the aedeagal apodeme is wider in T. cauga than in the other species of subgenus, and the hypoproct is narrower apically in T. cauga and T amazonensis . The three species can also be distinguished on the number of rod-like setae on the gonostylus, with T. menezesi having eight, T. cauga six and T. amazonensis nine setae.
