Description of a new species of the subgenus Hirtodrosophila (Drosophila: Drosophilidae: Diptera: Insecta) from Chandigarh, India

A new species belonging to the subgenus Hirtodrosophila of the genus Drosophila is described from Chandigarh, India. The relationship, based on the morphology, periphallic organs and phallic organs, at the subgeneric and generic levels is discussed in detail. This new species does not resemble, in external morphology, any of the species described so far. However, in the structures of periphallic and phallic organs it resembles to D. (H.) nokogiri Okada (1956) and D. (H.) histiroides Okada & Kurokawa (1957). The present species is characterized by the presence of a pair of paired black stripes separated by a silvery-white stripe on the mesonotum and scutellum.
