A review of the genus lordiphosa basden in India, with descriptions of four new species from the Himalayan region (Diptera, drosophilidae)

Abstract

All Indian species of the genus Lordiphosa Basden are reviewed, with descriptions of four new species, L. curva Fartyal & Toda, sp. n. of the denticeps species group and L. ayarpathaensis Kandpal & Singh, sp. n., L. makaibarensis Pradhan & Chatterjee, sp. n. and L. srinagarensis Sati & Fartyal, sp. n. of the nigricolor species group. Two of the new species, L. ayarpathaensis and L. makaibarensis, were found visiting flowers of Hedychium spicatum and Datura suaveolens, respectively. This is the first record of flower visitation in Lordiphosa flies. In addition, L. parantillaria (Kumar & Gupta, 1990), syn. n. is synonymized with L. antillaria (Okada, 1984). Supplementary and revised descriptions for L. antillaria and L. neokurokawai (Singh & Gupta, 1981) and a key to all Indian species of Lordiphosa are provided.
