Sex-dependent divergence in asymmetrical reproductive tract morphology between two closely-related amphisbaenian species (Squamata: Amphisbaenidae)

Comparing reproductive tract morphology between closely-related species may reveal mechanisms and processes leading to reproductive isolation and cladogenesis. Differences in external morphology are often inconspicuous between closely-related Neotropical species, and tissue samples for DNA sequencing are usually scarce for fossorial organisms such as amphisbaenians. Therefore, comparing characters of the reproductive tract between closely...
