The New Zealand species of Stethorus Weise (Coleoptera: Coccinellidae)

Abstract

Adults of the three New Zealand Stethorus species—S. bifidus Kapur, S. griseus Chazeau, and S. histrio Chazeau—are redescribed and keyed. Short descriptions of the last instarlarvae of S. bifidus and S. griseus are provided. Notes on nomenclature, affinities, distributions, and hosts are presented and a lectotype designated for 5. griseus. S. griseus Whitehead and S. incompletus Whitehead are nomina nuda and S. incompletus Chazeau is treated as a synonym of S. histrio. The record of the Australian species S. nigripes Kapur from New Zealand is incorrect.
