Trichomyia (Septemtrichomyia) Bravo

T. (Septemtrichomyia) Bravo, 1999: 1–2. Type species: Trichomyia botosaneanui Wagner , by original designation.

Other species included: T. amazonensis sp. nov. ( Brazil), T. atlantica sp. nov. ( Brazil), T. bou Bravo ( Brazil) , T. cauga Bravo ( Brazil) , T. dolichakis Quate ( Costa Rica, Panama), T. dolichopogon Alexander, Freitas & Quate ( Brazil) , T. dolichothrix Quate ( Panama) , T. imarui sp. nov. ( Brazil), T. jezeki sp. nov. ( Brazil), T. mishi Bravo ( Brazil) , T. pedrabranquensis Bravo ( Brazil) , T. sattelmairi Wagner & Masteller ( Puerto Rico) and T. sertaneja sp. nov ( Brazil).

According to Alexander et al. (2001), Trichomyia pedicillata Satchell , known only from the type locality in Panama, also has three pairs of long, hooked bristles on tergum 7, although the authors did not provide a formal description of this character nor of the material studied. This character was not included in the original description by Satchell (1956). We did not have access to the type material of T. pedicillata , and until new observations can be made, this species is not included in Septemtrichomyia.

Diagnosis. Head subcircular. Antenna with 13 pyriform and slightly asymmetrical flagellomeres. Maxillary palpus 3-segmented, first palp segment with inner sensorial pit; medial fork at the approximate center of the wing. Tergum 7 with pair of lateral lobes, each one with 3–5 elongate bristles on tergum 7, sometimes fused (as a single bristle). Hypandrium fused with gonocoxites. Gonocoxite with one posterior arm convergent to the midline, usually with rod-like setae on the inner margin. Gonostylus unsclerotized, ventrally articulated to the gonocoxite near the apex.

Comments. Bravo (1999) proposed that the gonostylus of the subgenus Septemtrichomyia has two distal arms, one dorsal arm and one ventral. However, based on a reexamination of the type specimens of T. bou , T. cauga and T. mishi and studies of new material, it is clear that there is only one arm (i.e. the second arm is actually the gonocoxite projected posteriorly). Bravo (1999) misinterpreted the gonostylus, which is ventral and articulated near the apex in all of the species of this subgenus.
