Nephochaetopteryx coxalis Dodge

( Fig. 37G )

Nephochaetopteryx coxalis Dodge, 1968a: 279 (key), 282 (description of female). Type locality: Brazil, Minas Gerais, Lassance. Other references: Pape (1996: 260; catalog); Mello-Patiu & Santos (2001: 305; description of female).

Type material examined. HOLOTYPE ♀ ( MNRJ): Lassance-Minas / 20 a 31.I.39 / Martins, Lopes / e Mangabeira [printed on rectangular white label] // Holotype [printed on rectangular red label] // HOLOTYPE / Nephochaetopteryx / coxalis / Det. H. R. Dodge 1964 DE [printed and handwritten on rectangular white label bordered with red] // MNRJ / 2197 [printed and handwritten on rectangular white label]. [Holotype in good condition.]

PARATYPE. ♀ ( MNRJ): Lassance-Minas / 20 a 31.I.39 / Martins, Lopes / e Mangabeira [printed and hand- written on rectangular white label] // Paratype [printed and handwritten on rectangular green label] // Nephochaeto / pteryx coxalis / PARATYPE / Det. H. R. Dodge [printed and handwritten on rectangular white label]. [Paratype missing its left antenna and left wing; abdomen cleared and dissected, preserved in glycerin in a microvial pinned beneath the specimen.]

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 ). 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.
