On the taxonomic validity of Indian ground spiders: VI. Genera Ladissa Simon, 1907, Melicymnis Simon, 1885, and Poecilochroa Westring, 1874 (Araneae: Gnaphosidae)

Indian species of the genera Ladissa Simon, 1907, Melicymnis Simon, 1885, and Poecilochroa Westring, 1874 are reviewed. The species Ladissa latecingulata Simon, 1907, and Melicymnis bicolor Simon, 1885 are considered as species inquirenda due to the immature stage of the types. The type locality of L. latecingulata is confirmed as in Pakistan, and its record in India is found incorrect. The following new combinations are recognised: Hitobia behni (Thorell, 1891) comb. nov., H. devendrai (Gajbe & Rane, 1985) comb. nov. and H. tikaderi (Patel, 1989) comb. nov. (all ex. Poecilochroa). Images of all the examined type specimens, and supplementary descriptions for P. barmani, H. behni comb. nov. and H. devendrai comb. nov. are presented.
