Probl. 34(1–2): 55–102. – The fifth and largest new species group Graphelmis picta is designated within the genus Graphelmis DELÈVE, 1968, comprising nine known and twenty five new species: G. picta (REITTER, 1886), G. biroi (BOLLOW, 1942), G. verpa JÄCH, 1985, G. binervosa (REITTER, 1886), G. diaphoroderes JÄCH, 1985, G. lomata JÄCH, 1985, G. oxytela JÄCH, 1985, G. pallidipes (CARTER, 1926), G. palawanensis sp.nov., G. ceylonica (MOTSCHULSKY, 1859), G. loebli sp.nov., G. jendeki sp.nov., G. kubani sp.nov., G. convexa sp.nov., G. balkei sp.nov., G. clava sp.nov., G. riberai sp.nov., G. picea sp.nov., G. vogleri sp.nov., G. basalis sp.nov., G. hlavaci sp.nov., G. securipes sp.nov., G. strbaki sp.nov., G. tuberculata sp.nov., G. philemoni sp.nov., G. togianica sp.nov., G. posoica sp.nov., G. reitteri sp.nov., G. insolita sp.nov., G. darwini sp.nov., G. schneideri sp.nov., G. jesusi sp.nov., G. bruneica sp.nov., G. gibberosa sp.nov. Habitus and detail drawings of characteristic structures of genitalia, pregenital segments and male metatibiae are given.

Key words: Coleoptera, Elmidae, Graphelmis, taxonomy, south-east Asia.

As the largest Many species of the G. picta species group are very group, it also has the widest area of distribution, extending similar to each other. The general appearance as well as from Sri Lanka in the west through the central part of south- male genitalia are often almost identical among species, east Asia and the Sunda Islands to New Guinea and north- but the combination of characters such as habitus, colour east Australia. The majority of the species (21) occurs in pattern, form and size of genitalia and apex of male New Guinea (Irian Jaya and Papua New Guinea), eleven metatibie is always unique for species. species occur in the central part of south-east Asia (Laos, Thailand, Vietnam, Borneo, Palawan, Siberut, Sumatra, Graphelmis picta (REITTER, 1886) Sulawesi), one species in Sri Lanka and one in Australia, (Figs 1, 10–13, 139) respectively.
