Spilopteromyia Malloch 1921b: 422 (description; type-species Spilogaster apicata Stein, by original designation); Snyder 1949: 1–39 (subgenus of Neomuscina; key); Snyder 1954: 423–429 (subgenus of Neomuscina; key); Pont 1972: 50 (synonym; catalogue).
Diagnosis: eyes bare; arista plumose; postalar wall bare; supra and infra squamal ridges bare; acrostichal 0:1, 1:1 or rarely 2:1; apical portion of the stem vein with setulae on dorsal and ventral surfaces; apex of vein M strongly curved, running upward and ending near the wing apex; vein R4+5 slightly curved downward and ending before meeting with the wing apex; calcar absent (Snyder 1949; Couri & de Carvalho 2002).
To avoid lengthy and redundant descriptions, the characters listed below, present in all species of Neomuscina mentioned in this article, will not be repeated: male holoptic, female dichoptic; paravertical setae small, parallel and directed backward; eye facets enlarged medially and posteriorly; antenna, in profile, not reaching epistome and inserted below middle of eye; arista plumose, dorsal cilia longer than ventral, with short cilia on the internal region; epistoma not prominent; palpus dilated apically; second pair of frontal setae stronger than other frontal setae; two supra-alar setae; pre-alar seta present; two notopleural setae; three humeral setae, inner seta reduced; post-humeral and pre-sutural seta present; a pair of small and basal scutellar setae; a pair of large and lateral scutellar setae; two pairs of pre-apical scutellar setae, inner pair smaller; a pair of strong and apical scutellar setae; without parahumeral and post-supra-alar setae; scutellar setulae intruding laterally on basal margin of scutellum; proepisternum and proepimeron with two prominent setae each; anepimeron with discal setulae; katepisternals 1:2; fore femora with a complete row of setae on dorsal, posterodorsal and posteroventral surfaces; mid tibia with a row of strong and weak setae interspersed from the middle of the anterior region of the posterior surface to the posteroventral surface, ending near the apex of the tibiae; hind femur with a posterodorsal preapical seta; male fifth sternite with concave apex and finger-like extensions (e.g. Figs. 1, 5, 11, 17); cercal plate fusiform, united at the middle (in posterior view) by a short connection (e.g. Figs. 3, 7, 13, 19); apex of cercus with two or three laterointernal setae (e.g. Figs. 3, 7, 13, 19); surstylus with internal setae (e.g. Figs. 2, 6, 12, 18); paramere with setulae (e.g. Figs. 4, 8, 14, 20); three rounded and rough spermathecae.
Comments: Some species of Neomuscina (e.g. N. transporta Snyder and Neomuscina currani Snyder) have been collected far from their natural area of distribution, suggesting that they might have been transported by humans. See localities details below, in the descriptions.
The following type-specimens, recorded to Brazil, were not examined by us: Neomuscina arcuata (Wiedemann) [lectotype: SMF; type-locality: ‘Brasilien’; distribution: Brazil], Neomuscina dorsipuncta (Stein) [syntypes: MSNM, ZMHB; type-locality: Oaxaca & Tapachula, Mexico; distribution: Brazil, Costa Rica, Mexico, Panama, Venezuela], Neomuscina sparsiplumata (Stein) [syntypes: NMW, ZMHB; type-locality: Rio Grande do Sul, Brazil; distribution: Brazil] and Neomuscina tinctinervis (Stein) [syntypes: MSNM; type-locality: Santa Catarina & São Paulo, Brazil; distribution: Brazil] (de Carvalho et al. 2005). Furthermore, these species were not found among the material from other collections; therefore, they were not included in the key. See Wiedemann (1830) and Stein (1918) for original descriptions.
