Reassessment of taxonomic characters for the plant bug genus Hypseloecus Reuter, with descriptions of new species of Hypseloecus and the related genus Lasiolabops Poppius (Heteroptera: Miridae: Phylinae)

Abstract

The Old World plant bug genus Hypseloecus Reuter of the tribe Pilophorini is reviewed on the basis of detailed observation of the morphological characters, with an updated checklist of Asian congeners. “Pleural glands” are herein suggested as a novel diagnostic character and currently considered as an additional autapomorphy for the genus. Two Asian new species, Hypseloecus nakagawai sp. n. (from Honshu, Japan) and H. aaroni sp. n. (Bagmati Zone, Nepal), are diagnosed and described. The host association and habitat of H. nakagawai are also documented. An Old World pilophorine genus, Lasiolabops Poppius, assumed to be a potential sister taxon of Hypseloecus, is diagnosed and discussed; further, two new species, L. cirratus sp. n. (from Japanese Ryukyus) and L. remicornis sp. n. (from Central Thailand), are described, based on their distinctive vestiture pattern.
