Redescription. Female. Length = 5.0–6.0 mm (n = 2).

Head. Fronto-orbital and parafacial plates, postocular strip, gena and postgena with golden microtomentum. Frontal vitta black with basal half reddish. Six frontal setae. Palpus yellow.

Thorax. Chaetotaxy: dorsocentrals 2+4 (first two small); intra-alars 2+3; supra-alars 2+3; anepisternals 6; merals 4. Fore-coxa light brown with yellowish microtomentum. Mid femur with three median setae and without a differentiated posteroventral seta. Wing hyaline, with a faint brown spot beginning in the terminal portion of vein R 1, filling the distal third of cell r 1 and the upper half of the distal half of cell r 2+3; vein R 4+5 setulose dorsally to crossvein r-m.

Abdomen. Tergites brown with a band of golden microtomentum on anterior 4/5 of dorsal and lateral surfaces. Sternites dark brown, silver-pollinose, covered with yellowish setulae and marginal setae.

Terminalia. As described by Mello-Patiu & Santos (2001, figs 5–6, 31).

Male. Unknown.

Distribution. NEOTROPICAL—Brazil ( Minas Gerais).

Remarks. This species was described based on three females which, according to Dodge (1968a), were characterized by having yellow fore coxa. The holotype and a paratype were examined and their fore coxa is light brown with yellowish microtomentum ( Fig. 37G View FIGURE 37 ). Some specimens of other species of Nephochaetopteryx also have a light brown fore coxa similar to that of N. coxalis . The type locality of Nephochaetopteryx coxalis is in Minas Gerais, and N. angustifrons and N. pallidifacies are the only other species recorded from this state. These species, as N. coxalis , also have a yellow palpus. However, the female terminalia of N. angustifrons are different from those of N. coxalis ( Mello-Patiu & Santos 2001) . The female terminalia of N. pallidifacies are unknown.
