Identification. Cephalic spines in lateral view robust, long and curved at apex; dorsum of propodeum with only one pair of, sometimes bifid, teeth; node of petiole in lat- eral view with oblique anterodorsal margin ending in a pair of robust posterodorsal spines; gaster with appressed hairs as well as short curved hairs; and hairs on legs ap- pressed and curved with the apex reaching the tegument (unpublished key by Kempf).

Distribution. The distribution of P. diversus includes northern Brazil, Ecuador, and Venezuela ( Kempf 1972; Brandão 1991; Fernández and Sendoya 2004; Ryder Wilkie et al. 2010). Our new distribution records for Colombia ( Fig. 1D ) corroborates the northern South American distribution for this species.
