Description of a new Tiporus Watts, 1985 from northern Queensland, Australia (Coleoptera: Dytiscidae, Hydroporinae)



Tiporus queenslandicus sp. n. is described from NE Queensland. The new species is similar to T. undecimmaculatus (Clark, 1862) and T. giuliani (Watts, 1978) from the Northern Territory and north-western Australia but well characterized by its larger size, more elongate habitus, and form of median lobe and parameres. Tiporus queenslandicus sp. n. is a lotic species being collected from rest pools of intermittent creeks and rivers with a sandy bottom. Important species-defining characters (habitus, median lobe, paramere, protibia of male) are illustrated. Together with T. queenslandicus sp. n. the genus comprises now 13 species.
