New species and rediagnosis of Akamboja, and a new record for A. minimum (Coleoptera: Phengodidae, Mastinocerinae)

Abstract

Akamboja was recently described based on five species with relatively small geographic ranges, all of which are within the boundaries of the South-eastern Atlantic Rainforest in Brazil. Recent expeditions in the continental island of Ilha Grande (Angra dos Reis, Rio de Janeiro State, Brazil) resulted in the discovery of a new species of the genus. Akamboja insularis sp. nov. has all diagnostic features of the genus, except for the branches of the antennomere IX, which are separated, unlike any other Akamboja. Here, we describe this new species, provide a new record for Akamboja minimum Roza et al. and propose a new diagnosis for the genus. urn:lsid:zoobank.org:pub:DC47825C-B276-49CC-88DC-DFDC5D843356.
