title: Candeocoris bistillatus, new genus and new species of Ochlerini from Ecuador (Hemiptera: Heteroptera: Pentatomidae).
abstract: Recent examination of specimens from Ecuador revealed a series of males and females of an undescribed species clearly belonging to the Discocephalinae. The new species presents characteristics similar to genera of both Discocephalini and Ochlerini, preventing an undoubtful placement of the new species within any genus and tribe. We conducted a cladistic analysis to investigate the possible relationships of the new species within Discocephalinae. The new species was recovered as sister-group to the remaining Ochlerini, supporting the proposition of a new genus, so Candeocoris bistillatus Roell & Campos, gen. n. et sp. n. are described within Ochlerini. The new genus is recognized for its dark glossy aspect, tumid vertex of head, long and sinuous labrum, base of labium placed close to anterior limit of eyes, thick bristles on meso- and metatibiae, pygophore globose, and laterotergites 9 touching each other. The new species is recognized by a large yellow spot on each corium, yellow spots on each segment of the connexivum, bucculae with anterior tooth, laminar projections on superior layer of ventral rim of pygophore, vesica with a single median projection, and broad gonocoxites 8.
