Lobosciara trilobata Vilkamaa & Hippa, 1994

( Fig. 13 A –C)

Literature: Vilkamaa & Hippa (1994): 41–48.

Material: 1 male, 3.vii.2000, Palm Cove, near Cairns, mangrove forest along the coastline, caught by net, leg. W. Mohrig (PWMP).

Comments. Lob. trilobata is characteriZed by a long gonocoxal apodeme and a broad intergonocoxal lobe in between. Species of this genus differ considerably from all other sciarids in the structure of the male hypopygium. They are mainly characteriZed by a simple gonostylus – long and narrow, slightly curved and without an apical tooth or spines. The apex and the inner side have rather long hairs. Unusual structures (quite different from all known sciarid genera) characteriZe the ventral base of the hypopygium. The inner ventral base of the gonocoxite is lobe-like and prolonged (gonocoxal apodeme), the apodemes are of different lengths and densely haired at the apex (in Lob. latilobata Vilkamaa & Hippa, 1994 it is broadly rounded and with short hairs). In some species there is an additional structure at the ventral base of the hypopygium, an intergonocoxal lobe between the gonocoxal apodeme (divided as in Lob. latilobata or apically straight as in Lobosciara trilobata ). The five known species are distributed in the Malay Archipelago (Borneo, Malay Peninsula, Sulawesi), Thailand, Micronesia and Australia.

Distribution. Australia, Queensland; Indonesia, Sulawesi.
