Neomuscina maculata sp. nov. Pereira-Colavite & Carvalho

( Figs. 47–52 )

Diagnosis: acrostichal 1:1; dorsocentral 2:4; intra-alars 2; mid femur with three preapical setae; lateral region of postalar callus with a distinctive dark brown mark; male: fifth sternite square; female: sternite VI with many setulae near apex.

Color: general body coloration brownish yellow; frons yellow, apex brown; facialia and parafacialia white; gena, antenna and palpus yellow; scutum brown with four light stripes of grey pruinosity; humeral callus and apex of scutellum yellow; lateral region of postalar callus with a distinctive dark brown mark; calypters yellowish white, with darkened borders; halter yellowish white; wing hyaline.

Male. Length. Body: 5.7 mm; wing: 6.3 mm.

Head: eyes separated from each other by 0.12 mm, at level of ocellar tubercle; 13 pairs of convergent frontal setae; ocellar seta large and parallel; postocellar seta small and divergent; inner vertical seta small and convergent; outer vertical seta small and divergent.

Thorax: acrostichal 1:1; dorsocentral 2:4; intra-alars 2; proepisternum and proepimeron with one setae; fore tibia with a distinct submedian anterodorsal seta; apex of fore tibia with setae on dorsal, posterodorsal, posteroventral and ventral surfaces; mid femur with a row of setae on posterior, posteroventral and anteroventral surfaces from base to middle, reappearing near the apex; mid femur with three preapical setae, on dorsal, posterodorsal and posterior surfaces; apex of mid tibia with setae on anterior, anterodorsal, dorsal, posterodorsal, posterior, posteroventral, ventral and anteroventral surfaces; hind femur with a complete row of dorsal and anteroventral setae, and a row of posteroventral setae from base to middle, reappearing near apex; hind tibia with one submedian anterodorsal setae and two submedian anteroventral setae; hind tibia with anterior, anterodorsal, dorsal, posterodorsal, ventral and anteroventral setae at apex; wing with one dorsal and two ventral setae at apex of stem vein.

Abdomen: fifth sternite with a near rectangular shape; apex of fifth sternite with reduced concavity; cercus, in profile, tapered.

Female (differing as follows): Length. Body: 5.7 mm; wing: 6.3 mm; eyes separated from each other by 0.3 mm, at level of ocellar tubercle; 12 pairs of frontal convergent setae, except for top two pairs, which are divergent; ocellar seta large and postocellar seta small, both divergent; inner vertical seta large and convergent, and outer vertical seta small and divergent; acrostichal 0:1; proepisternum and proepimeron with two setae; hind tibia with four submedian anteroventral setae; sternite VIII with strong spike-like setae; epiproct with six setae, setae in a hexagon-shaped arrangement (2:2:2).

Comments: N. maculata sp. nov. is similar to N. zosteris , differing externally only by the three pre-apical setae of mid femur and a distinct brown mark on the postalar callus. The males have a fifth sternite with a subrectangular shape and the apex with reduced concavity. Females have sternite VIII with strong spike-like setae and epiproct with six setae.

Etymology: it refers to the distinct dark brown mark in the lateral region of postalar callus.
