Material. Holotype ɗ, BRAZIL, State of Amapá, Serra do Navio, 00º 53’S 52º 00’W, 2/X/1957, K. Lenko col. (MZSP); paratypes: 1 Ψ, same as holotype (MZSP); 1 ɗ, idem but Ricolté col. (MZSP); 1 ɗ, idem but Pereira & Machado cols. (MZSP)
Diagnosis. Wing membrane homogeneously brownish, longer than wide; maxillary palpus slender at base, distally enlarged; gonostylus swollen, strongly truncated distally; ejaculatory and gonocoxal apodemes long, both exceeding base of terminalia.
Male. Body length, 10.0–11.0 mm. Wing length, 7.0– 7.5 mm. General color yellowish brown. Eyes blue, facets homogenous, ocellar tubercle dark gray, ocelli grayish. Gena dark gray. Clypeus bare, yellowish to brown. Antenna yellowish to brown; scape bare, wider and shorter than pedicel; pedicel cubic; first flagellomere suboval (Figure 76). Maxillary palpus long, slender basally, distally enlarged (Figure 77). Proboscis and labella yellowish. Occiput gray, with golden setae.
Thorax homogeneously brownish yellow. Halter bare, yellowish brown. Legs yellowish, with golden setae. Wing membrane homogeneously brownish (Figure 75); pterostigma pigmented, elongated; R2+3 reaching C far from R1, without distal sinuosity; R4 forking with almost right angle, with slight distal curve toward anterior margin, without short appendage; CuA2 and A1 fusing far from margin; M3 long; crossvein m-m almost reaching origin of M2.
Abdomen brownish yellow, both tergites and sternites of last three segments darker. Gonocoxite and gonostylus dark brown; terminalia wider than long; gonostylus slender basally, strongly truncated distally, covered with long setae, short setae at base; aedeagus short; ejaculatory and gonocoxal apodemes long, both exceeding base of terminalia; lateral ejaculatory process wide and short (Figure 79); meso-anterior incision of tergite IX short (Figure 80); cercus yellowish brown.
Female. Body length, 8.2–9.0 mm. Wing length, 5.8–6.0 mm. Thorax and abdomen similar to male. Anterior margin of sternite VIII acuminate, hypogynial valves with 6-7 long setae (Figure 82); genital fork with anterior end strongly acuminate, distal apodemes well pronounced (Figure 83); cercus two-segmented, distal segment suboval (Figure 81); common spermathecal ducts short, spermathecal ducts long; spermathecae oblong (Figure 78).
Distribution. All known specimens of this species are from the type-locality, in the State of Amapá, northern Brazil.
Etymology. The species name comes from a fusion of the Greek words phaios, for dusky, brown, and pteron, for wing, as a reference to the homogeneously brown smoked wings.
