description: Trichomyia pseudoannae Araújo & Bravo sp. nov.   
(Figs. 1.1 –9 and 2.1–3)  
Diagnosis.Head with one row of supraocular alveoli and one row of occipital alveoli. Palpus with three segments. Male terminalia with hypandrium fused to gonocoxites and expanded posteriorly as a apically slightly bifucate plate covering the aedeagus, gonocoxite with two pairs of arms.Female with the subgenital plate trapezoidal and bifurcated apically, cerci elongated.  
Description.  
 Male. Head subcircular, eyes rounded. Supraocular setae in single row (Fig. 1.3). Occipital setae arranged in single row (Fig. 1.4). Antennal pit subtriangular, short distance between antennae (less than 1/3 of the width of the pits and with sclerotic fold). Scape subcylindrical and pedicel subespherical, basal flagellomeres pyriform and eccentric; with a pair of mediobasal digitiform and S-shaped ascoids, first and second flagellomere equal in length, ascoids 1.4 times length of flagellomere (Fig. 1.1). Palpus three-segmented; first segment with sensilla in depressed pit on inner side; palpus formula: 1.0:0.6:0.9 (Fig. 1.5). Wing (Fig. 1.2). Sc-r sclerotized but not microsetose, r-m present, radial fork distal of apices of CuA 2 and medial fork, base of M 2 sclerotized but without microsetae. Male terminalia. Hypandrium fused with gonocoxites and expanded posteriorly as an apically slightly bifucate plate covering the aedeagus. Two pairs of arms of gonocoxite (Fig. 1.8: agd, agv), one dorsal, directed to apical region and with fine bristles distributed irregularly and a ventral pair, longer than dorsal one, directed to internal region of genitalia at an angle of 60 ◦. Pair of dorsal arms digitiform, with row of rod-like setae at apex and simple bristles distributed irregularly. Gonostylus sub-circular, slightly sclerotized and with fine bristles, articulated with ventral region of gonocoxite (Fig. 1.8). Gonocoxal apodeme with medium, narrow and sclerotized projection directed to dorsal region of genitalia (Fig.1.6 and 1.8). Aedeagus bifid; two pairs of parameres, dorsal lanciform and ventral digitiform, ejaculatory apodeme long, 1.75 times length of parameres (Fig. 1.9). Cercus cuneiform with bristles distributed irregularly. Hypoproct with micropilosity and apex rounded. Epandrium trapezoidal and pilose, with alveoli distributed in two lateral patches (Fig. 1.7).   
Female.Head, antennae, mouthparts, palpi and wings as in male. Female terminalia. subgenital plate trapezoidal bifurcated apically. Cerci elongate, about 5.2 times longer than wide; sclerotized arch between cerci acuminate and with microseate, 0.4 as long as cerci (Fig. 2.1 and 2.3). Spermathecae with ducts annulated, inflated apically, apex slightly truncated. Median apodeme with two sclerotized projections anteriorly and three posteriorly; median posterior projection three times longer than other projections (Fig. 2.2).

 Etymology. The epithet refers to morphological similarity with Trichomyia annae Bravo, 2001.   
Distribution. Known only from the type locality.  
 Comments. The new species is morphologically similar to Trichomyia annae. The differences are in the male terminalia, the plate expanded posteriorly of hypandrium and gonocoxites has a small bifurcation apically with projections on rounded apex and not lanciform as in T. annae. Both species, to date, have not been included in any subgenus.
