Abstract

ABSTRACT: The large-sized species of the genus Eupiestus Kraatz were reviewed taxonomically. Eupiestus miriceps Fauvel, 1902, is redescribed with a detailed illustration of the male genital parts. Eupiestus giganteus Shibata, 1991, was synonymised with E. callosus Fauvel, 1902. Eupiestus miriceps and E. spinifer were newly recorded from the Malay Peninsula (Malaysia: Selangor) and Laos, respectively. Habitus photographs of all species including the holotype of E. spinifer var. unicolor Cameron are given. A key for the identification of large-sized Eupiestus species and the list of the world Eupiestus species are provided. Observation of the mid-gut contents suggests that Eupiestus species are fungivorous, at least in adults of a few species.
