New Upinella Mulsant, 1856 (Coleoptera: Tenebrionidae: Alleculinae: Alleculini) species with description of a new subgenus Marunella subgen. nov. from the Oriental Region.

A new subgenus of Upinella Mulsant, 1856 - Marunella subgen. nov. with a type species Upinella (Marunella) laosica sp. nov. from north Laos (Houaphanh Province) is described, illustrated including male genitalia and compared with other subgenera of Upinella (Thornella Novák, 2019, Tibinella Novák, 2019 and Upinella s. str.). Males of species of the new subgenus distinctly differ from the others mainly by the elytral suture and elytral intervals 2, 4 and 6 distinctly raised like a roof in the middle and by the scutellum being raised above the level of the elytron. Further new species of Upinella Mulsant, 1856 from the Oriental Region are described as follows: Upinella (Upinella) basorica sp. nov. from peninsular Malaysia (Kelantan Province), Upinella (Upinella) kokutica sp. nov. from Thailand (Trat Province) and Upinella (Upinella) xiengica sp. nov. from Laos (Xieng Khouang Province). All new species are described, illustrated and compared with habitually similar species. [ABSTRACT FROM AUTHOR]
