E-mail: scydmaenus@yahoo.com Abstract Bellendenker palpalis gen. et sp. nov. is described based on specimens collected in northeastern Australia. The genus is unique among glandulariine Scydmaeninae in strikingly elongated labial palps, which are longer than the labium; no mod- ifications of labial palps have been known so far in this large tribe. Bellendenker is most similar to the Australian genus Scydmaenozila Jałoszyński, they share similar thoracic structures. Numerous differences in cephalic characters can be used to distinguish these genera; moreover, adults of Bellendenker are wingless and have reduced structures of the elytral base. Fourteen genera of Glandulariini (plus one of unclear status, known only from original description) are currently known to occur in Australia, eight being endemic to this continent. Key words: Coleoptera, Scydmaeninae, Australia, new genus, new species Introduction Among over 230 nominal species and subspecies of Scydmaeninae that occur in Australia, nearly 80% belong to the tribe Glandulariini. Thirteen out of fourteen genera can be identified, only one, Psepharobius King, 1864, is known from a vague and unclear original description, and as the depository of type specimens of its sole species is unknown, its status and identity remain unclear. The latest reviews and revisions include those of Jałoszyński (2004, 2012a, 2013, 2014a, b, c, d, 2015) and cover all Australian species of Euconnus (Napochus Thomson, 1859), Horaeomorphus Schaufuss, 1889, Leascydmus Jałoszyński, 2014a, Microscydmus Saulcy & Croissandeau, 1893, Palaeoscydmaenus Franz, 1975, Penicillidmus Jałoszyński, 2014b, Sciacharis (Magellanoconnus Franz, 1967), Sciacharoides Jałoszyński, 2014a, Scydmaenilla King, 1864, Scydmaenozila Jałoszyński, 2014a, Scydmepitoxis Jałoszyński, 2014c, Spinosciacharis Jałoszyński, 2014a, and Syndicus Motschulsky, 1851. Species belonging to other subgenera of Euconnus Thomson, 1859 and Sciacharis Broun, 1839 require revision, but both genera have been already redefined based on extensive morphological studies and can be identified (Jałoszyński 2012b, 2014e). The true diversity of Australian Glandulariini is many times higher than that recorded so far, with several genera and hundreds of species awaiting description. The present study is focused on a new genus showing uniquely modified mouthparts, discovered in a large (several thousand specimens) material of Scydmaeninae housed at the Australian National Insect Collection.
