When the first impression is not what counts: Two striking new species of Schuhocoris (Rhyparochromidae: Rhyparochrominae: Antillocorini)

Abstract

The rhyparochromid tribe Antillocorini is a cosmopolitan group of very small to minute true bugs distributed in the tropics and subtropics, extending to the temperate regions but also well represented in oceanic islands in the Pacific. In America, 19 genera are present, all with species distributed in the Neotropics. The monotypic genus Schuhocoris Slater, 1985 was described from Peru, Panama and Brazil. Here we expand the characters’ set defining Schuhocoris, and describe two new species in the genus, Schuhocoris ecuatorianus n. sp. and S. slateri n. sp., both from Ecuador, that present abdominal modifications compatible with stridulatory structures, something not reported for members of the tribe so far. Dorsal and lateral habitus photographs, along with images of relevant external characters and from the pygophore and parameres of the new species are given, and the presence and morphology of stridulatory devices are discussed.
