Evolutionary implications of hemipenial morphology in the terrestrial Australian elapid snakes
Venomous proteroglyphous or 'elapid' snakes are distributed across much of the tropical and subtropical world but are most diverse in Australia. Due to differing opinions of character weight and problems associated with high levels of homoplasy in traditionally used snake character systems, there is no well accepted hypothesis of phylogenetic relationships for the Australian elapids. Moreover, few or no synapomorphies have been identified to define many of the 20 currently recognized genera. As...[Show more]
