Bravo [white label, printed] // Trichomyia inermis Barretto / Det.Freddy Bravo, 2004 [white label, printed] ’; 1J ( MZFS), labelled:‘ BRAZIL, AM / Manacapuru / Cajatuba, Km 69/3/ CDC copa Lote 011 / 20.IV.1998 / Col.

Do / Cajatuba , Sítio do Sr. / Simplício CDC (copa) / 24–25.IV.1999 [white label, printed] ’.

Diagnosis. Male. Palpus with sensilla in depressed pits on segments 1 and 2 ( Fig. 1 ); segment 4 of palpus 1.2 times the length of third segment ( Fig. 1 ); ascoids 1 and 2 of the same length, ascoid longer than flagellomere ( Fig. 2 ); radial fork apical to medial fork; CuA 2 ending after medial fork ( Fig. 3 ); posterior arms of gonocoxite with lateral margins sinuous in dorsal view, with feathered bristles on the entire surface of inner margin ( Figs 4, 6 ); gonostylus present, blade-shaped, straight, approximately the same length as gonocoxal arm ( Figs 4, 7 ); without ventral tubercle on gonocoxite; cercus trapezoidal in ventral view; distal margin of cercus of the same length as ventral margin ( BARRETTO 1954: Fig. 14); cercus subrectangular in ventral view ( Fig. 5 ); ejaculatory apodeme long, as long as arm of gonocoxite ( Fig. 7 ). Female unknown.

Distribution. Brazil, states of São Paulo, Bahia (new record) and Amazonas (new record).

Remarks. The initial description of the male terminalia of T. inermis given by BARRETTO (1954) provided only a lateral view, which made the identification of the species more difficult. The holotype is on a permanent slide and was not remounted; therefore, the redescription was based on new material.
