Abstract

The genus Urumaelmis Satô, 1963 is recorded for the first time from China. A new species, Urumaelmis yunnanensis sp. nov. is described from Yunnan, China. The new species can be distinguished from U. uenoi uenoi (Nomura, 1961) and U. u. tokarana (Satô, 1963) by its larger body size, and by the carina on elytral interval VI which extends nearly from base to apex; and from U. flammea Nakajima & Kamite, 2020 also by its black body color, the median groove of pronotum not reaching the base, pointed anterior pronotal angles, and by the absence of parameres. The habitus, and aedeagus photos, and line drawings of the male genitalia are provided.
