Neomuscina capalta Snyder 1949: 5 (key), 17 (description); Snyder 1954: 424 (key); Pont 1972: 50 (catalogue); d’Almeida 1993: 7 –16 (synanthropy); de Carvalho et al. 1993: 57 (catalogue); Couri & de Carvalho 2002: 152 (key); Couri & de Carvalho 2005: 9 (listed); de Carvalho et al. 2005: 93 (catalogue); Rodríguez-Fernández et al. 2006: 98 (listed).
Diagnosis: acrostichal 0:1; dorsocentral 2:3; mid femur with two preapical setae; calypters with darkened borders; male: cercus, in posterior view, more dilated at base than at apex.
Color: general body coloration yellowish brown; apex of frons darkened; facialia, parafacialia, gena, antenna and palpus yellow; scutum with four light stripes with grey pruinosity; legs yellowish brown; calypters brownish white, with darkened borders; wing hyaline, with dark cloud running from Sc to apex of R1, weakening and becoming stronger on apex of R2+3; r-m and dm-cu with brownish clouds.
Male. Length. Body: 5.8–6.1 mm; wing: 6.0– 6.1 mm.
Head: eyes separated from each other by 0.07–0.11 mm at level of ocellar tubercle; 14–15 pairs of frontal setae; ocellar seta large and convergent; 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-alar 1; apex of fore tibia with setae on anterodorsal, dorsal, posterodorsal and ventral surfaces; fore femur with a row of setae on anteroventral surface, from base to middle, then reappearing near apex; mid femur with row of setae on antero and posteroventral surfaces from base to middle; mid femur with two preapical setae, on posterodorsal and posterior surfaces; apex of mid tibia with setae on anterior, posterodorsal, posteroventral, ventral and anteroventral surfaces; hind femur with a complete row of dorsal and anteroventral setae; hind tibia with one median anterodorsal seta and two to three median anteroventral setae; hind tibia with anterior, anterodorsal, dorsal and anteroventral setae at the apex; wing with one dorsal and one or two ventral setae at apex of stem vein.
Abdomen: epandrium lightly projected at base; cercus, in posterior view, more dilated at base than at apex.
Female (differing as follows): Length. Body: 5.8–6.0 mm; wing: 6.1–6.2 mm; eyes separated from each other by 0.28–0.3 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; intra-alars 2; numerous setae between sternites VI and VII; sternite VIII with weak spike-like setae; square-shaped epiproct with four setae (2:2).
Comments: the males described here are similar to the description by Snyder (1949). However, the females (from Brazil), believed to be conspecific with the males described above, have 2 intra-alars, unlike the females from Panama, which have 1 intra-alar as reported by Snyder. The material analyzed by Snyder has not been found. Neomuscina capalta has also been collected on species of the fungi genus Fomes Fries (Snyder 1949; 1954).
Holotype (not examined): AMNH. Type-locality: Port of Spain, Trinidad and Tobago.
