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.

The genus Lordiphosa Basden is a moderately-sized genus of the family Drosophilidae, currently comprising 57 species (
The genus Lordiphosa is distributed from the tropics of Oriental Region (
Four new species of Lordiphosa have been discovered from India. Two of them were found visiting flowers of Hedychium spicatum Smith (Zingiberaceae) in Kumaon, Uttarakhand and of Datura suaveolens (Humb. & Bonpl. exWilld.) Bercht. & J. Presl (Solanaceae) in Darjeeling, West Bengal. Until now, Lordiphosa flies were known for breeding on herbage plants, and their larvae feeding on decayed tissues of leaves and stems (
Specimens used for the present study were collected from four different hill stations of the Himalayan region in India: Chopta (2,700 m a.s.l.; 30°29'N, 79°10'E) in Rudraprayag district; Ayarpatha (2,278 m a.s.l.; 29°23'N, 79°27'E) in Nainital district; Kurseong subdivision of Darjeeling hills (1,458 m a.s.l.; 26°53'N, 88°17'E) in West Bengal; and HNBGU Forestry nursery (560 m a.s.l.; 30°13'N, 78°47'E) at Chauras Srinagar Garhwal in Uttarakhand. These localities are covered with dense mixed-deciduous subtropical forests, under extremely moist condition due to heavy rainfall during the summer monsoon season. The temperature ranges approximately from 3°C to 24°C. Specimens were collected by net sweeping or directly from flowers of Hedychium spicatum and Datura suaveolens by an aspirator, and preserved in 70% ethanol. In addition, some specimens collected from China were examined to give supplementary and revised descriptions for some known species.
External morphology of adult flies was examined under a stereomicroscope and metric characters were measured with an ocular micrometer. To observe detailed structures, the male and female terminalia and some other organs were detached from the body, cleared by warming in 10% KOH solution at approximately 100°C for several minutes, mounted in a droplet of glycerin on a cavity slide, examined under a light microscope, and some samples imaged using a DinoLite® Digital Eyepiece Camera.

This species closely resembles Lordiphosa penicilla (Zhang, 1993) from southwestern China in the morphology of male terminalia, but can be distinguished from it by the diagnostic characters: in L. penicilla, surstylus medially pubescent and with several stout setae on outer surface; sclerotized ventral branches of parameres symmetric in length; gonopod with single medial ridge in lateral view (
In this study, it was found that L. neokurokawai has a special type of sex comb composed of thick setae of approximately 15 TBRs along the entire length of tarsomere I of male foreleg (Fig.
