Popis:	Mitotic and meiotic chromosomal karyotypes have been described for Gegeneophis ramaswamii and G. usp (unspecified species). Based on the available karyological information from among the eight species of Gegeneophis, a tentative scheme is proposed for their karyotypic phylogeny. A closer scrutiny of one of the two in an otherwise homologous chromosomal pair (chromosome number 13) in the complement is suggestive of a XX-XY sex-chromosome differentiation.
