Material examined. COLOMBIA. Meta: 1 ♂, Pto. López, Cafam Llanos , Cgto. Remolinos, Hda. Santa Teresa, 4°18’N, 72°33’W, light trap, 14.ix.2010 (J. García) ( ICN 092935 ) ; 1 ♀, San Martín, Fca. Caduceo, near Río Carmen , 400 m, 12–­ 13.v.2006 (G. Aveo) ( ICN 092934 ) ; 1 ♂, PNN Sierra de La Macarena, Casino , 490 m, 3º21’N, 73º56’W, Malaise trap, 21.iv–13.v.2004 (W.

Diagnosis. Body yellow, orange to red, with brown and black areas. Head in dorsal view, clavus and posterior part of corium dark brown to black. Pronotum orange to red. Embolium yellow. Eyes conspicuously pilose between ommatidia. Body length 2.40–2.80 mm ( Carvalho 1947a; Carvalho & Gomes 1971b). Right paramere ( Fig. 65 ) with basal process wider towards the body; body sub-oval, slightly concave; apical process, flat, spatulate, with terete apex. Left paramere ( Fig. 66 ) with basal process short and straight; body curved and slightly concave; apical process flat, spatulate, with tapered apex.

Associated/host plants. Unknown.

Distribution. Argentina , Brazil ( Carvalho & Gomes 1971b), Costa Rica ( Hemp & Konrad 2000), Panama ( Carvalho & Gomes 1971b; Carvalho & Afonso 1977).— Colombia (Meta).

Comments. This is the first record of this species in Colombia. Pilosity within the ommatidia was not considered in the original description. According to Hemp & Konrad (2000), P. pilosus is attracted to cantharidin.

We have nine specimens belonging to this genus, which we couldn’t place to species. The genus is in need of revision.
