Tortopsis bruchianus (Navás) New combination

Campsurus bruchianus Navás 1926: 110 . Tortopus bruchianus ; Domínguez 1987: 9.

Material ( MACN): lectotype and 2 paralectotypes female adults from Argentina, Córdoba, Alta Gracia, La Granja, 20/I/1924, Bruch col. One paralectotype is pinned, the other females are in alcohol.

Discussion and diagnosis. This species is known only from female imagos, redescribed and illustrated in Domínguez (1987). Tortopsis bruchianus can be recognized by: 1) fore wing length 17.5 (18.5–19.0 in Domínguez 1987); 2) wings whitish translucent except longitudinal veins near costal margin shaded purplish brownish on proximal half; 3) female parastylus receptors C-shaped (similar to Fig. 46 ); 4) head shaded black between ocelli, occiput apparently without dark markings (not well visible); 5) the sublateral pale marks on posterior ring of female pronotum are present but not very visible. T. bruchianus is very similar to T. sarae , presently they can only be separated by egg color with T. bruchianus having orange eggs whereas the eggs of T. sarae are yellowish in color.
