Neomuscina similata Snyder 1949: 6 (key), 33 (description); Snyder 1954: 428 (key); Pont 1972: 51 (catalogue); Linhares 1981: 231 (synanthropy); d’Almeida 1993: 7 –16 (synanthropy); de Carvalho et al. 1993: 59 (catalogue); Couri & de Carvalho 2002: 154 (key); de Carvalho et al. 2002: 107 –114 (synanthropy key); Couri & de Carvalho 2005: 9 (listed); de Carvalho et al. 2005: 97 (catalogue); Couri & de Carvalho 2005: 9 (listed).
Diagnosis: acrostichal 0:1; dorsocentral 2:4; male: intra-alars 2; mid femur with three preapical setae; wing with dark cloud running from Sc to R1; R2+3 with dark cloud on apex; r-m and dm-cu with dark cloud; male: fifth sternite with strong basal projection; female: sternite VIII with spike-like setae.
Color: general body coloration brownish yellow; frons yellow, apex darkened; facialia, parafacialia, gena, antenna and palpus yellow; scutum brownish yellow with four dark stripes of grey pruinosity; median and hind femora apex dark brown; calypters and halter yellow; wing hyaline, with dark cloud running from Sc to R1; R2+3 with dark cloud on apex; r-m and dm-cu with dark cloud.
Male. Length. Body: 6.6–7.1 mm; wing: 6.4–7.0 mm.
Head: eyes separated from each other by 0.12 mm, at level of ocellar tubercle; 12 pairs of convergent 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 2:4; intra-alars 2; fore tibia with distinct median anterodorsal setae; apex of fore tibia with setae on anterior, posterodorsal and posteroventral surfaces; mid femur with row of setae on ventral surface from base to middle; mid femur with two preapical setae, on posterodorsal and posterior surfaces; apex of mid tibia with setae on anterior, dorsal, posterodorsal, posteroventral, ventral and anteroventral surfaces; hind femur with complete row of dorsal and anteroventral setae, and row of posteroventral setae from base to middle; hind tibia with one median anterodorsal seta and three median anteroventral setae; hind tibia with anterior, anterodorsal, dorsal, posterodorsal, ventral and anteroventral setae at apex; wing with one dorsal and one or two ventral setae at apex of stem vein.
Abdomen: fifth sternite projected at base.
Female (differing as follows): Length. Body: 6.0– 6.1 mm; wing: 6.5 mm; eyes separated from each other by 0.2 mm, at level of ocellar tubercle; 10-11 pairs of frontal convergent setae, except for upper two pairs, parallel; ocellar seta large and postocellar seta small, both divergent; inner vertical seta large and convergent, and outer vertical seta large and divergent; sternite VIII with spike-like setae; epiproct with four setae, setae in a squareshaped arrangement (2:2).
Comments: as indicated by Snyder (1949), N. similata is quite similar to N. nigricosta, differing mainly in coloration and especially in the dark cloud pattern on the wing, between veins Sc and R1 and R2+3 apex. The males have a fifth sternite projected at the base and the females have a characteristic sternite VIII with spike-like setae.
Holotype (not examined): AMNH. Type-locality: Port of Spain, Trinidad and Tobago.
