Diagnosis

Males of Tekellina minor resemble those of T. bella by the large paracymbium, but differ by the shorter terminal claw of the conductor ( Figs 2G–H , 4B ). Females resemble those of T. bella by the shape of the epigynum, but differ by the smaller receptacles and copulation ducts ( Figs 2I , 4A ).
