Antillocladius antecalvus Saether, 1981: 4 , Fig. 2 ; Spies and Reiss (1996: 75); Mendes et al. (2004: 27 , Fig. 2 ).

Material examined: Type material as in Saether (1981). BRAZIL: Santa Catarina: São Bento do Sul , 26°19'25.6''S, 48°18'26.5''W , 1 male, 13–16.x.2001, Malaise trap, M.V. Yamada. Paraná: Morretes, Parque Estadual do Pau Oco , 25°34'27.9''S 48°53'46.7''W , 2 males, 07–10.iv.2002, Malaise trap (Bosque-2), M.T. Tavares et al. ( BIOTA-FAPESP) ; 1 male as previous except for (Trilha-3); 2 males as previous except for (Bosque-1); 2 males as previous except for 10–13.iv.2002, (Bosque-2); 1 male as previous except for (Trilha- 4); 2 males as previous except for (Bosque-1); 1 male as previous except for (Bosque-4). São Paulo: Pedregulho, Furna São Pedro , 1 male with pupal exuviae, 7.vii.2000, S. Mateus. Rio de Janeiro: Nova Iguaçu, Reserva Biológica Tinguá, 22°34'30''S 43°26'07''W , 1 male, 5–8.iii.2002, Malaise trap (Trilha-4), S.T.P. Amarante et al.; 1 male as previous, except for 8–11.iii.2002; 1 male as previous except for 22°34'27''S 43°26'11.4''W, 5–8.iii.2002, (Bosque-6). VENEZUELA: Aragua: Parque Nacional Henri Pittier, Rancho Grande , 10°21.047'N, 67°41.198'W , about 1000 m a.s.l., 21 males, 16–18.ix.1999, sweep net & light trap, T. Andersen. Falcón: Rio Mitare near San Luis, 11°07.930'N, 69°39,184'W , 589 m a.s.l., 18 males, 7.vi.2001, light trap, R.W. Holzenthal, R. Blahnik, H. Paprocki & C. Cressa ( MIZA, MZUSP, UFSCar, ZMBN) .

Diagnostic characters: The male can be separated from all other members of the genus by having 0–3 apical setae on the wing membrane; squama with 1–3 setae; few scalpellate or non-scalpellate acrostichals in mid scutum; virga absent; and inferior volsella large with anterior bare, strongly set off rounded projection and low posterior lobe. The female differs from other known females by having tergite IX undivided, but tergite setae still in two groups. The pupa has thorn-like macrosetae and anal lobe laterally expanded.

Distribution: The species is known from Saint Vincent and Venezuela, and from Santa Catarina, Paraná, São Paulo, and Rio de Janeiro States in Brazil.
