Skrjabinodon trimorphi and Skrjabinodon poicilandri are described from the recta of the New Zealand common skink (Leiolopisma nigriplantare polychroma Patterson and Daugherty, 1990) and the New Zealand common gecko (Hoplodactylus maculatus Boulenger, 1885), respectively. Analysis of proteins from these 2 species was carried out using gel electrophoresis (starch and cellulose acetate) and polyacrylamide isoelectric focusing. Five enzyme-encoding loci were revealed as useful for species separation. Each species consisted of a monomorphic female and dimorphic males. Population structure, morphology, and biochemical data supported the case for male dimorphism.
