Description (main diagnostic features only). Hairs (rays) on arista (antennal segment 6) all short and non-seriate, or absent; mesoscutum much wider than long; scutellum with only two or three pairs of bristles, all restricted to posterior half of its length or less; mesopleuron largely shining, with pruinescence-pubescence restricted to anteroventral part or absent; sternopleural bristle weakly differentiated from adjacent setulae or absent; mid femur without ventral spines; length of first section of vein 4 more than 0.7 of length of discal cell measured along vein 4; second section of vein 5 usually longer than anal crossvein; squama large; female: abdomen with large tergite 3, tergites 4 and 5 vestigial, often desclerotized; male: aedeagus with complex sclerotized glans, without hollow terminal filaments.

Distribution Australasian Region: New Guinea, Australia (including Lord Howe Island), Solomon Archipelago, New

Caledonia. Oriental Region: Philippines, Sumatra (e.g., N. imitans de Meijere ), but some species recorded from other countries probably not referable to genus (see McAlpine, 2001). Afrotropical Region: widely distributed in African tropics, Madagascar. New Caledonia apparently represents the eastern limit of the range of the genus, as the Fijian record is an error.

Notes

Naupoda is a diverse and widely distributed genus, and has perhaps not been adequately defined as a monophyletic taxon. The subgenus Gonga McAlpine, 2001 , which contains exclusively the known Australasian species, is distinguished as given by McAlpine (2001: table 3), except that the frontoorbital bristle is not always distinct.

The following key to species is preliminary, as it is based on the limited material at present on hand. Naupoda “sp. 1” is an apparently undescribed species from the East Sepik and Central Provinces of Papua New Guinea ( AM) .
