NORTHERN RECORDS OF THE GENUS CULISETA FELT IN AUSTRALIA WITH THE DESCRIPTION OF A NEW SPECIES (DIPTERA: CULICIDAE)

i
Culiseta arenivaga sp.n., described from females from Fraser Island, Queensland, provides the northernmost record of Culiseta in Australia. C. arenivaga has postspiracular setae and it is compared in text and figures with the other species known from Queensland, C. antipodea Dobrotworsky, and with the other species possessing postspiracular setae, C. littleri (Taylor), C. inconspicua (Lee), and C. atra (Lee), of which the first two are the only species known from New South Wales. Postspiracular setae are reported in C. inconspicua for the first time. C. littleri is recorded from northern New South Wales and geographical variation in this species is discussed. The unusual palmate empodium of C. antipodea females is described and figured. Relationships within the genus are considered and an austral origin for the genus is suggested.
