Review of the Dyschiriodes (Eudyschirius) of the species group Orientalis (Coleoptera, Carabidae) with a revision of Indo-Malayan species

A recently established Paleontropical, mostly Oriental, group of species, orientalis of the genus Dyschiriodes Jeannel, 1941 is reviewed. Indo-Malayan species of the group are revised and keyed. Three new species, D. contortus sp. n. and D. himalaicus sp. n., both from India, and D. natalensis sp. n. from South Africa are described. The following new synonyms were specified: D. speculifer (Andrewes, 1929) (= D. aeger (Andrewes, 1929), syn. n.); D. orientalis (Putzeys, 1866) (= D. indicus (Putzeys, 1866), syn. n.; = D. maculipennis (Habu, 1975), syn. n.).
