Diagnosis: vein R4+5 with one ventral seta at the base; acrostichal 0:1; dorsocentral 2:3; male: fifth sternite with bilobed projection at the base; surstylus narrow and not sinuous, with large inner setulae; cercus with two apical, lateral and inner setulae; paramere with an prominent setula; female: ovipositor short and faintly sclerotized; epiproct with five setulae, in a x-shaped arrangement (2:1:2).
Color: general body coloration yellowish brown; frons yellow, apex darkened; facialia and parafacialia white; gena, antenna and palpus yellow; scutum with two light stripes of grey pruinosity; legs yellowish brown; calypters brownish white; halter yellow; wing hyaline, with dark cloud running from Sc to apex of R1; r-m and dm-cu with brownish clouds.
Male. Length. Body: 5.3–5.8 mm; wing: 6.0– 6.1 mm.
Head: eyes separated from each other by 0.07–0.08 mm at level of ocellar tubercle; 12–14 pairs of frontal setae; ocellar seta large and parallel; postocellar seta large and divergent; inner vertical seta small and convergent; outer vertical seta small and divergent.
Thorax: acrostichal 0:1; dorsocentral 2:3; intra-alars 2; apex of fore tibia with setae on anterodorsal, dorsal, posterodorsal and posteroventral surfaces; mid femur with a row of setae on anterior and anteroventral surfaces from base to middle; mid femur with three preapical setae, on dorsal, posterodorsal and posterior surfaces; apex of mid tibia with setae on the anterior, posterodorsal, posterior, posteroventral, ventral and anteroventral surfaces; hind femur with a complete row of dorsal and anteroventral setae; hind femur with strong anteroventral setae at the apex; hind tibia with one median anterodorsal seta and three median anteroventral setae; hind tibia with anterior, anterodorsal, dorsal, ventral and anteroventral setae at the apex; wing with one dorsal and two ventral setae at the apex of stem vein; R4+5 with one ventral seta at the base.
Abdomen: epandrium narrow in profile and projected at the base; fifth sternite with lobed projection at the base; surstylus not sinuous, with large internal setae; cercus sharply excavated apically, with two large setae on inner side; cercus narrow in profile; paramere with a large and pronounced setae; aedeagal apodeme and epiphallus forming a right angle.
Female (differing as follows): Length. Body: 5.5–6.0 mm; wing: 5.8–6.0 mm; eyes separated from each other by 0.27–0.31 mm at level of ocellar tubercle; 9–10 pairs of frontal convergent setae, except for top two pairs, which are parallel; ocellar and postocellar setae large and divergent; inner vertical seta large and convergent, and outer vertical seta large and divergent; ovipositor short; tergite VI absent, tergite VII faint and tergite VIII with sclerotized borders; triangle-shaped sternites VI and VII faint; sternite VIII with weak spike-like setae; epiproct with five setae, setae in a x-shaped arrangement (2:1:2).
Comments: As N. atincticosta, N. currani is very distinct from other Neomuscina. Males are characterized by the narrow epandrium and projected at the base, the fifth sternite with lobed projection at the base and the surstyli not sinuous, with large internal setae. The cerci are sharply excavated apically, with two large setae on the inner side. The paramere has one large and pronounced seta, and the aedeagal apodeme and epiphallus form a right angle with each other. The females have a short ovipositor, with tergite VI absent, tergite VII faint and tergite VIII with sclerotized borders. The sternites VI and VII are faint and triangle-shaped and the epiproct has five setae. It is the only species described for this genus that has one ventral seta at base of vein R4+5. This seta led Snyder (1949) to believe this species is intermediate between his typical Neomuscina sensu stricto, without ventral setae at base of vein R4+5, and his concept of Neomuscina (Spilopteromyia), with ventral setae.
