Revision of the ‘nudidrosophila’ and ‘ateledrosophila’ species groups of Hawaiian Drosophila (Diptera: Drosophilidae), with descriptions of twenty-two new species

Abstract

Abstract The ‘nudidrosophila’ and ‘ateledrosophila’ species groups, formerly described as genera, are a relatively small and understudied part of the enormous Hawaiian Drosophila radiation. Only nine species were described previously. Here we revise the two groups, provide a key to males and females, and describe fully all species. The ‘ateledrosophila’ group now contains three species, D. diamphidia Hardy, D. papala sp.n., and D. preapicula Hardy. The 28 species of the ‘nudidrosophila’ group are separated into five subgroups: ‘hirtitibia’ (D. hirtitibia Hardy, D. konaensis sp.n., D. mawaena sp.n., and D. papaalai sp.n.); ‘kahania’ (D. kahania sp.n. and D. longipalpus sp.n.); ‘nudidrosophila’ (D. aenicta Hardy, D. amita Hardy, D. canavalia sp.n., D. eximia Hardy, D. gemmula Hardy, D. kualapa sp.n., D. lepidobregma Hardy, D. mahui sp.n., D. malele sp.n., D. panoanoa sp.n., and D. poonia sp.n.); ‘okala’ (D. akoko sp.n., D. kuhao sp.n., D. makawao sp.n., D. okala sp.n., and D. panina sp.n.); and ‘velata’ (D. halapepe sp.n., D. kauaiensis sp.n., D. lauoho sp.n., D. milolii sp.n., D. pohaka sp.n., and D. velata Hardy).
