Type-locality. Guatemala.

Type material. Holotype, examined, labeled: a) Type; b) Guatimala (sic) 52 119; c) Canaca abrupta ( BMNH) .

Dorsal surface reddish-castaneous, abdominal venter castaneous, more reddish on laterals. Humeri directed laterad, tougher than in the other species, apex blackish ( fig. 2 ). Rostrum attaining third sternite. V-shaped callous of scutellum thin.

Genitalia ( fig. 3 ). Gonocoxites 8 quadrangular, about one and a half wider than long. Sutural borders contiguous at apical two thirds. Posterior borders of gonocoxites 8 almost rectilineal. Laterotergites 9 almost as long as gonocoxites 8, slightly surpassing the transversal band linking laterotergites 8.

Comments. This species, known only from the holotype, may be distinguished from the other congeners by its tougher, laterally directed humeri, and by the shape of gonocoxites 8.
