Neomuscina ponti Lopes & Khouri, 1995

Neomuscina ponti Lopes & Khouri 1995: 48 (description), 50 figs. 6–10 (respectively: fifth sternite; cercal plate, frontal view; cercal plate, lateral view; aedeagus, frontal view; aedeagus, lateral view); Couri & de Carvalho 2002: 150 (key); de Carvalho et al. 2005: 96 (catalogue).

Diagnosis: acrostichal 2:1; dorsocentral 2:4; intra-alars 2; mid femur with two preapical setae, on posterodorsal and posterior surfaces; wing hyaline.

Color: general body coloration brownish yellow; frons yellow, apex brown; facialia, parafacialia and gena brownish yellow; antenna and palpus dark yellow; scutum with four dark stripes of grey pruinosity; calypters white, with darkened borders; halter yellow; wing hyaline.

Male. Length. Body: 5 mm; wing: 6.2 mm.

Head: eyes separated from each other by 0.08 mm, at level of ocellar tubercle; ten pairs of convergent frontal setae, except the last two parallel pairs; ocellar seta large and parallel; postocellar seta large and divergent; inner vertical and outer vertical setae small and divergent.

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

Abdomen: missing.

Female: unknown.

Comments: N. ponti can be easily distinguished by the acrostichals 2:1. In many aspects, it is similar to N. zosteris . However, the terminalia of the holotype of N. ponti is lost, and these two species will be kept separate here until new specimens are collected. Snyder (1949: 10) pointed that his morphospecies ‘ Neomuscina species 1’ from Santa Cruz, Rio Grande do Sul ( Brazil) is quite similar to N. zosteris , except for having two presutural acrostichals, similarly to N. ponti . For drawings of the terminalia see Lopes & Khouri (1995: 50).

Type material examined: Holotype: male, specimen and chaetotaxy well preserved; microvial with glycerin pinned with the specimen, but the terminalia is missing; label: white, printed “ BRASIL, São Paulo, Campinas / XII-77, A.X. Linhares col.”; label: red, printed HOLOTYPE ( MNRJ). Type-locality: Campinas, São Paulo, Brazil.

Geographical distribution: Brazil (São Paulo [type-locality]).
