Oxysarcodexia culmiforceps Dodge, 1966: 687 .

Distribution: Neotropical – Argentina (Buenos Aires, Entre Ríos, Misiones), Brazil (Minas Gerais, Paraná, Rio de Janeiro, Rio Grande do Sul, Santa Catarina, São Paulo), Paraguay.

Material studied: Buenos Aires: 4 ɗ, 4 Ψ Campana, Campana, XI.1998, Mariluis leg. ( ANLIS); 24 ɗ, 1 Ψ Campana, Campana, III–IV.2003, Mariluis leg. ( ANLIS); 1 ɗ San Isidro, Magdalena, VII.1998 ( FAUBA); 1 ɗ San Isidro, Magdalena, 25.VIII.1998 ( FAUBA); 2 ɗ El Carretero, Magdalena, V.1999 ( FAUBA), 1 ɗ El Carretero, Magdalena, VII.1999 ( FAUBA); 1 ɗ, 2 Ψ El Carretero, Magdalena, IX.1999 on Scutia buxifolia ( FAUBA); 1 Ψ El Carretero, Magdalena, 3.XI.1999 ( FAUBA); 1 Ψ Punta Lara, Ensenada, 19.XI.2003 on Sebastiana brasiliensis ( FAUBA).

Remarks: Dodge (1966) described O. culmiforceps and suggested it was misidentified by Lopes (1946b) as O. culminata (Aldrich) . Dodge (1966) restricted the name O. culmiforceps to those specimens “with thorax entirely gray pollinose”. Lopes (1975), agreed with the identification made by Dodge, but suggested that O. culmiforceps is highly variable in colour and some details of cerci and phallus, and reported that Blanchard misidentified this species under the name O. meridionalis (Engel) . Blanchard (1939) and Lopes (1946b) provided good illustrations of O. culmiforceps (as O. meridionalis and O. culminata , respectively). Additionally, Tibana & Mello (1983) provided illustrations of female terminalia.

Biology: In Brazil, some studies indicate that O. culmiforceps is an abundant species throughout the year, with a tendency to avoid urban areas ( Ferreira 1979; Linhares 1981; Dias et al. 1984a, b). This species is mostly attracted to faeces baits ( Ferreira 1979; Dias et al. 1984c). Flower visitor of Euphorbiaceae ( Sebastiana brasiliensis ) and Rhamnaceae ( Scutia buxifolia ).
