Determining the sex of Australian Gecko Species
Below are some typical diagrams of sex determining variations between the sexes in Nephrurus, Oedura and Strophurus species.
The common variances in the ventral section gives a relatively good understanding on distinguishing the relevant sex of some species.
Typically males tend to have very advanced enlargements in that area due to the hemipenes. This area is not obviously pronounced in females. The following images are of adult specimens which are easier to identify. It can be quite confusing when sexing juveniles until they reach at least 6–8 months of age.
The Nephrurus species shown in the example below is a Nephrurus Asper. In most cases the sexing of Nephrurus Amyae and Nephrurus Sheai will be similar to the Nephrurus Asper.
Similar sex variations due to the hemipenes in males compared to females can also be noted for most of the Smooth Knob Tailed Gecko species.
