Key to the species of Gegeneophis

The following dichotomous key should serve to differentiate the six described species of Gegeneophis . The species that are most likely to be confused are the two southernmost species G. r a m a s w a m i i and G. c a r n o s u s. These species may overlap in their numbers of primary and secondary annuli, and G. c a r n o s u s particularly resemble small G. ramaswamii . Determining the visibility of the eye may be difficult without a microscope and good lighting, especially with small specimens.

1 Secondary annuli and annular grooves absent .............................................. seshachari

­ Secondary annuli and annular grooves present ............................................................ 2

2 Secondary annular grooves present anteriorly, even within first 20 primary annuli ...... .............................................................................................................................. danieli

­ Secondary annular grooves restricted to posterior half or less of body ........................ 3

3 More than 120 primary annuli ............................................................................. krishni

­ Less than 120 primary annuli ....................................................................................... 4

4 Eyes not visible externally ......................................................................... ramaswamii

­ Eyes visible externally .................................................................................................. 5

5 Less than 100 primary annuli ............................................................................... fulleri
