Neomuscina transporta Snyder, 1949

( Figs. 119–122 )

Neomuscina transporta Snyder 1949: 5 (key), 23 (description), 25 (comments about the distribution); Snyder 1954: 428 (key); Pont 1972: 51 (catalogue); de Carvalho et al. 1993: 59 (catalogue); Lopes & Khouri 1996: 957 (near N. mimosa ); Couri & de Carvalho 2002: 153 (key); de Carvalho et al. 2005: 98 (catalogue).

Diagnosis: acrostichal 0:1; dorsocentral 2:4; mid femur with two preapical setae; wing hyaline, with dark cloud dark cloud running from Sc to R1; R2+3 with dark cloud on apex; male: fifth sternite with basal projection and groove in concavity.

Color: general body coloration yellow; frons yellow, apex brown; facialia white; parafacialia, gena, antenna and palpus yellow; scutum with grey pruinosity; calypters white; halter yellow; wing hyaline, with dark cloud running from Sc to R1; R2+3 with dark cloud on apex.

Male. Length. Body: 5.0– 5.3 mm; wing: 5.5 mm.

Head: eyes separated from each other by 0.1–0.11 mm, at level of ocellar tubercle; 14–15 pairs of convergent frontal setae; ocellar seta small and parallel; postocellar seta small and divergent; inner vertical seta small and convergent; outer vertical seta small and divergent.

Thorax: acrostichal 0:1; dorsocentral 2:4; intra-alar 1; proepisternum with three setae; apex of fore tibia with setae on anterodorsal, dorsal, posterodorsal and posteroventral surfaces; mid femur with row of setae on posteroventral surface from base to middle; mid femur with two preapical setae, on posterodorsal and posterior surfaces; apex of mid tibia with setae on anterior, anterodorsal, dorsal, posterodorsal, posterior, posteroventral, ventral and anteroventral surfaces; hind femur with complete row of dorsal and anteroventral setae, and row of anterodorsal and ventral setae from base to middle; hind tibia with one or two submedian anterodorsal setae and four submedian anteroventral setae; hind tibia with anterior, anterodorsal, dorsal, anteroventral setae at apex; wing with one dorsal and one ventral setae at apex of stem vein.

Abdomen: fifth sternite projected at base; bearing strongly projected, fingerlike extensions; epandrium, in profile, rounded.

Female (differing as follows): Length. Body: 5.0 mm; wing: 5.6 mm; eyes separated from each other by 0.26 mm, at level of ocellar tubercle; 11 pairs of frontal convergent setae, except for upper two pairs, parallel; ocellar and postocellar setae large and divergent; inner vertical seta large and convergent, and outer vertical seta large and divergent; intra-alars 2; hind tibia with one submedian anterodorsal setae.

Comments: originally collected in Ghana, Africa, this species has raised several questions since its discovery. Despite 16 months of intermittent collections in Accra, no specimen was obtained ( Snyder 1949: 25). However, Snyder indicated that this species was easily collected in Central America and eastern South America — without mentioning the localities. We have assumed that N. transporta , as the specific epithet says, was transported to Ghana by airplane. Only male specimens were dissected by us. The fifth sternite of the male is quite different from that of other species of the genus. The holotype has two median anterodorsal setae on the hind tibia, a characteristic not found on the female paratype and other conspecific specimens examined.

Type material examined: Holotype: male; mounted on a triangle; chaetotaxy in good conditions; fore right leg missing; right wing broken next to the base; label: red, handwritten “ Holotype male / Neomuscina / transporta / Snyder” | label: red, printed “Stat. Accra / Afr. IX-6–43 / MA Locke A660 / 43–17789” ( USNM). Type-locality: Accra, Ghana.

Paratypes: GHANA: 1 female “Allotype female / Neomuscina / transporta / Snyder | Stat. Accra / Afr. IX- 6–43 / MA Locke A660 / 43-17789” ( USNM).

Other material examined: BRAZIL. Sergipe. 5 males “ BRASIL, SE, Santa Luzia do Itanhy Crasto / 11º22’39,6” S 37º25’04,4” / W, Malaise – Armadilha – Trilha 1 / 1-4.VIII.2001, M.T. Tavares & eq. col.” ( MZUSP).

Geographical distribution: Brazil (Sergipe [new rec.]), Ghana (type-locality).
