Pailsus Gen. Nov.
Type species: Pailsus pailsei sp. nov.
Diagnosis (Genus): Large venomous elapids, believed to be most
closely related to the King Brown Snakes (Genus Pseudechis, sometimes
called Cannia), to which both may eventually be assigned as cogeneric
(of the same genus). These snakes are thought to reach about 1-1.5 metres
in maximum adult length. Specimens in excess of 2 metres are probably rare.
Currently known only from the Mount Isa area in Queensland. May be distinguished
from Pseudechis australis in the same area by the fact that most
if not all subcaudals are single while in Pseudechis australis,
about 20 posterior subcaudals are usually divided. Further separated from
Pseudechis australis by the proportionately smaller and less broad
head and generally more gracile build. Separated from Pseudonaja
by the all or mainly single subcaudals versus the all or mainly paired
subcaudals in Pseudonaja and lack of orange or brown markings on
the ventral surface in Pailsus. Pailsus is not likely to
be confused with any other genus of snake.
Etymology: Named after Roy Pails of Ballarat, Victoria; (refer
to species pailsei).
