Diagnosis.

U. maai maai is similar to U. boonei sp. nov. in general aspect, but the following remarkable differences enable its reliable separation from the latter species: vertex with blackish marking (lacking in U. boonei ); decoration of pronotum distinctly delimited, with brownish spots at humeral angles (indistinctly delimited, somewhat blurred, spots at humeral angles lacking in U. boonei , compare Figs 8A , 10A ); punctation of pronotum sparse and coarse, pronotum with impunctate “collar” anteriad to callosities (with fine, dense punctation and without significant impunctate areas in U. boonei ).

Distribution.

The species is distributed from Thailand to Borneo and Java and has data from the following ecoregions: Northern Khorat Plateau moist deciduous forests, Southeast Indochina dry evergreen forests, Peninsular Malaysian rainforests, Kinabalu montane alpine meadows, Borneo lowland rainforests, Sundaland heath forests, and Eastern Java-Bali rainforests.
