A New Flightless Dolichoctis (Coleoptera: Carabidae) From Sumbawa

The genus Dolichoctis, of the tribe Lebiini, includes a large numberof small Carabidae of the Oriental-Australian area. They arecharacterized by size (length often c 5 mm or less), by detailsof the mouthparts (which need not be given here — see Darlirgton1968, 124), and almost always by presence of 2 minute punctureswithout setae on the posterior half of the third interval of eachetytron. Most are arboreal, occurring often in under-story foliageof rain forest, although a few species probably occur in leaf litteron the ground. All previously known Dolichoctis are fully winged,so far as I know. The finding of a species in which wing atrophy hasoccurred is therefore of special interest. Atrophy of wings is infact. rare among all the Lebiini of the Indo-Australian islands: of16o members of he tribe found on New Guinea. only one hasreduced wings (Nototarus papua Darlington 1968, 186). Of coursewing atrophy is very common among some other Carabidae in someother parts of the world (Darlington 1936; 1943)
