Neomuscina Townsend, 1919

Neomuscina Townsend 1919: 541 (type-species designation Neomuscina cavicola , synonym of Muscina tripunctata Wulp, 1896 ); Curran 1934a: 399 (key to Nearctic species); Snyder 1949: 1 –39 (review, key); Snyder 1954: 423 (key to genus), 424 (key to species), 425–429 (review); Pont 1972: 50 (catalogue); Albuquerque & Lopes 1982: 56 (near Neomuciniopsis); de Carvalho & Couri 1991: 37 –38 (collected); de Carvalho et al. 1993: 57 (catalogue); Moura et al.

1997: 273 (listed; forensic); Couri & de Carvalho 2002: 149 (key); de Carvalho et al. 2005: 92 (catalogue); de Carvalho & Mello-Patiu 2008: 395 (forensic key).

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.
