Three new species, four new records, and an updated species key for males of Trichomyia (Brachiotrichomyia) Bravo & Araújo, 2013 (Diptera, Psychodidae)

Three new species of Trichomyia (Brachiotrichoyia) (Trichomyiinae, Psychodidae), Trichomyia spatulata sp.  nov., Trichomyia ciliata sp.  nov., and Trichomyia recurva sp.  nov. are described and illustrated. Additionally, we present new  re‐ cords of Trichomyia (Brachiotrichoyia) armata Barretto, 1954, Trichomyia (Brachiotrichoyia) quatei Bravo, 2001, Trichomyia (Brachiotrichoyia) inermis Barreto, 1954, and Trichomyia (Brachiotrichoyia) plumata Bravo & Araújo, 2013 in Brazil. An identifi‐ cation key for males of the subgenus was updated to include the three new species. Key-Words. New species; Moth‐flies; Brazil; Neotropical Region.


INTRODUCTION
is a neotropical subgenus of Trichomyia Haliday in Curtis, 1839 included in the subfamily Trichomyiinae (Psychodidae) with seven described species: T. (B.) armata Barretto, 1954;T. (B.) brasiliensis Satchell, 1956;T. (B.) inermis Barretto, 1954;T. (B.) plumata Bravo & Araújo, 2013;T. (B.) quatei Bravo, 2001 from Brazil;T. (B.) pseudodactylis Quate, 1996 from Costa Rica;and T. (B.) risaraldensis Bejarano, Pérez-Doria & Sierra, 2009b from Colombia . The species of this subgenus can be easily recognized by the presence of four segments in the palpi, where the first two segments are partially fused, by the fusion of gonocoxites with hypandrium and by the posterior projection of the gonocoxites as long arms that each have long bristles at a proximal margin .
Here are described three new species of Trichomyia (Brachiotrichoyia) from Brazil and included in the identification key of for the species of Trichomyia (Brachiotrichoyia) proposed by . Moreover, four new records are presented.

MATERIALS AND METHODS
The specimens examined in this study were cleared with 10% potassium hydroxide (KOH), dehydrated in ethanol, and mounted with Canada balsam on slides. The type specimens were deposited in Coleção Entomológica Professor Johann Becker do Museu de Zoologia da Universidade Estadual de Feira de Santana, Bahia, Brazil (MZFS). Terminology follows Cumming & Wood (2009) and the specific terminology of Psychodidae follows Wagner & Ibáñez-Bernal (2009). The term "arm of gonocoxite" refers to the posterior expansion of each gonocoxite. Description: Male: Head wider than long. Supraocular and occipital bristles arranged in a single row. Antennal socket quadrangular (Fig. 1A). Palpus with four segments, with the first two proximal, not observed articular membrane between them; first and second segments of palpus with sensilla in concave pit; fourth segment of palpus 1.2 times the length of third segment; palpus formula 1.0:0.9:0.9:1.0 (Fig. 1B). Antenna with flagellum lost; scape subcylindrical and pedicel subspherical approximately the same length (Fig. 1A). Wing folded in anal area in the preparation: apex of Sc without bristles, base of R₄₊₅ without bristles; r-m absent; medial fork basal to radial fork; CuA₂ ending approximately at the same point as medial fork (Fig. 1C). Male terminalia: hypandrium and gonocoxites fused dorsally; gonocoxite longer than wide, glabrous; posterior arms of gonocoxite digitiform in dorsal view, approximately the same length of gonostylus, folded at apex, convergent, with feathered bristles on apex; gonostylus present, paddle-shaped, glabrous; cercus teardrop-shaped in ventral view (Fig. 1D); epandrium wider than long, glabrous, subrectangular; ejaculatory apodeme 0.6 times the length of gonocoxal arm (Fig. 1E); hypoproct ending near cerci with dorsal micropilosity; finger-like (Fig. 1E).

Etymology:
The term originates from the Latin word spatulata, meaning spatulated, and refers to the shape of gonostylus.
Distribution: Known only from the type locality.

Remarks:
The male terminalia of the new species T. spatulata is similar to T. plumata by the teardrop-shaped form of the cercus and by the curved gonocoxite arms that converge to midline. The two species are differen- tiated by the format of the gonostylus, which is bladeshaped in T. plumata and paddle-shaped in the new species.

Trichomyia (Brachiotrichoyia) ciliata Araújo & Bravo sp. nov. (Figs. 2A-G)
Diagnosis: Sensilla in concave pits on segments of the palpi 1 and 2; fourth segment of palpus 1.2 times the length of third segment; CuA₂ ending approximately at the same point as medial fork; ejaculatory apodeme 1.4 times the length of the gonocoxal arm; cercus subrectangular in ventral view; posterior arms of gonocoxite convergent, with feathered bristles along ⅔ apical; gonosty-lus blade-shaped, straight, pointy apex, approximately the same length of gonocoxal arm.
Distribution: Known only from the type locality.

Remarks:
The new species and T. inermis are morphologically similar by the presence of feathered bristles in the arm of gonocoxite and by the elongated cercus with subparallel lateral margins. They differ by the length of the ejaculatory apodeme, which is long and narrow in T. inermis and short and wide in T. ciliata sp. nov.

Trichomyia (Brachiotrichoyia) recurva Araújo & Bravo sp. nov. (Figs. 3A-G)
Diagnosis: Sensilla in concave pits on segments of the palpi 1 and 2; fourth segment of palpus with the same length of third segment; CuA₂ ending approximately at the same point as medial fork; ejaculatory apodeme approximately the same length of gonocoxal arm; the cercus is elongated with a base wider than apex and the apex is bent; posterior arms of gonocoxite divergent, with feathered bristles throughout the arm, the apex directed outwards; gonostylus small, hemicircular.

Etymology:
The term originates from the Latin word recurva, meaning bent back on itself or bent round, which refers to the shape the cercus apex.
Distribution: Known only from the type locality.

Remarks:
The new species differs from other species of Trichomyia (Brachiotrichoyia) mainly, by the form of the cercus, which is wider in the base than the bent apex and by the arched arms of gonocoxite.
