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 (

Thorax homogeneously brownish yellow. Halter bare, yellowish brown. Legs yellowish, with golden setae. Wing membrane homogeneously brownish (

); 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.
