Echinotermes biriba , a new genus and species of soldierless termite from the Colombian and Peruvian Amazon (Termitidae, Apicotermitinae).

A new Apicotermitinae genus and species Echinotermes biriba is described from workers collected on the Andean-Amazon Piedmont in Colombia and Peru. The enteric valve armature of Echinotermes biriba Castro & Scheffrahn, gen. et sp. n. is a remarkably diagnostic character. A Bayesian phylogenetic analysis using the COI gene and including all other Neotropical Apicotermitinae genera, supports the new genus as a distinct terminal.
