Holcobunus bicornutus (Mello-Leitão, 1940)

Paratamboicus bicornutus Mello-Leitão, 1940: 97; Ringuelet, 1954: 297; Roewer, 1953:256; Crawford, 1992: 37; Tourinho & Kury, 2001: 9, figs. 1–13.

Diagnosis. Holcobunus bicornutus is know only by the juvenile holotype, although it can be separated from the other species of Holcobunus by the eye mound armed with two anterior blunt spines, longer than in other species (see Tourinho & Kury, 2001, Figs 9 and 11), and by the anterior leg I much shorter than body when compared to other species (see Tourinho & Kury, 2001, Fig.11).
