Diatrichalus mancus ( Kleine, 1926: 176)

( Figs 6 , 15–16 )

= Trichalus mancus Kleine, 1926: 176 .

Material examined. Male, Australia, Queensland, Pascoe River , Xing 34812, G. Monteith, riparian rainforest, 12° 54´S ; 143° 0´E (A0298; LMBC).

Remark. Here, I report for the first time D. mancus from the lowland forests of the Cape York Peninsula in Australia. To date, the species was only known from the southern coast of New Guinea ( Bocak, 2001). Although the ranges of net-winged beetles are regularly small and same species seldom occur in landmasses divided by the sea, the Torres Strait is a shallow sea, which turned in a savannah corridor connecting Australia and New Guinea during the last glacial maximum ( Webster & Streten 1978). Unlike the lycid species occurring only in the humid mountains, the dispersal abilities of Diatrichalus are extensive. The genus has spread similarly as Microtrichalus and Metriorrhynchus Gemminger & Harold , 1 869 to the Great Sundas in the north ( Bocak et al. 2006, Sklenarova et al. 2013).
