The two known Indian species of the genus Graptostethus Stal i.e. nigriceps Stal and quadrisignatus Distant have been studied in detail both for morphological characters as well as for male and female external genitalia. Illustrations have been given for all the morphological and genitalic structures for the first time. A key to the species is also provided.
