( MZSP ); paratypes : 1 Ψ, same as holotype ( MZSP ); 1 ɗ, idem but Ricolté col. ( MZSP ); 1 ɗ, idem but Pereira & Machado cols. ( MZSP ) Diagnosis.

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 ).

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.
