Diagnosis. Males of K. martamarta can be distinguished from other species by having an RTA in which the dorsal apophysis is longer than the ventral one and is truncate distally and by a large, twisted conductor ( Figs 29– 30 ).

Life history and habitat preferences. See Crews and Harvey (2011).

Remarks. Colours and patterns of the preserved material may not correspond to live specimens because of collection in ethylene glycol. Immatures were assigned to this species based on collecting localities.
