We recognize two new species of Ghatiana , and three new species of Sahyadriana , from the Western Ghats of India. Ghatiana durrelli n. sp. is characterized mainly by the proportionately narrower adult carapace, the relatively broader male pleonal somite 6, and the relatively stouter terminal segment of the male first gonopod. Ghatiana rouxi n. sp. is differentiated from congeners by its proportionately narrower adult carapace with the gently convex lateral margins. Sahyadriana inopinata n. sp. is characterized by a suite of characters that includes the visible epibranchial tooth, the relatively slenderer and longer terminal segment of the male first gonopod, and the subovate and relatively smaller adult vulva that is positioned a clear distance from the suture between thoracic sternites 5 and 6. Sahyadriana keshari n. sp. differs from the allied S. waghi () by the relatively stouter terminal segment of the male first gonopod, and the relatively larger adult vulva, which is positioned close to the suture between thoracic sternites 5 and 6. Sahyadriana tamhini n. sp. most resembles S. alcocki () but can be differentiated by its relatively longer, distally distinctly narrow terminal segment and the sinuous inner margin of the subterminal segment of the male first gonopod, and the relatively closely positioned and larger adult vulvae. Ghatiana and Sahyadriana now include 10 species and 13 species, respectively. An updated key is provided for both genera.
