Description
Summary:A new material of the genus Hercostomus Loew, 1857 has been recently found and identified. Hercostomus tomkovichi sp. n. from Meghalaya State of eastern India is described and illustrated. The new species differs from other representatives of the genus mainly in the morphology of the male hind leg and genitalia. Gymnopternus bitinctus (Becker, 1922), comb. n., is declared as a nomen dubium ; Gymnopternus gregalis (Becker, 1922), comb. n., is excluded from the Indian list; Hercostomus geminatus Becker, 1922 is transferred to the genus Pseudohercostomus Stackelberg, 1931; hence a new combination is made: Pseudohercostomus geminatus (Becker, 1922), comb. n. Now, nine Hercostomus species are known from the country. An identification key to species of Hercostomus from India is provided.
