One the genus Tocama Reitter (Coleoptera, Scarabaeidae, Melolonthinae), with descriptions of two new species from Indochina

Abstract

Two new species of the Oriental scarab genus Tocama Reitter, 1902, Tocama laosensis sp. n. and Tocama procera sp. n., are described from Indochina with diagnoses, distributions, remarks and illustrations. A key to the species of the genus is provided with a checklist with several nomenclatural changes: Hoplosternus tonkinensis Moser, 1913 is transferred to Tocama; Hoplosternus pygidialis Moser, 1915 syn. n., Tocama atra atra Keith, 2006 syn. n. and Tocama atra reichenbachi Keith, 2007 syn. n. = Tocama tonkinensis (Moser).

A new species of the genus Tocama Reitter, 1902 (Coleoptera: Scarabaeidae, Melolonthinae) from China

“…Reitter (1902) considered this genus as a subgenus of Melolontha Fabricius, 1775, and Kryzhanovskij (1978) elevated Tocama to the generic level depending on male genitalia. After Kryzhanovskij (1978), eight new taxa were described in this genus, and several taxa were also transferred into Tocama (Keith 2006(Keith , 2007Li et al, 2010;Keith & Sabatinelli 2012;Li et al 2012;Wang et al, 2015). New species of Tocama is described below.…”
