Remarks:
This specimen mostly agrees with the description of the
holotype
, a male specimen from South
Australia
. Red dorsal markings proposed as diagnostic character (
Staples 2007
) are not evident in this preserved female, instead scattered traces of red pigmentation are observed dorsally on trunk and legs. The shape of ocular tubercle, neck and proboscis agree well with those in the male, also the abdomen, although only slightly constricted distally, and the shape of chelae fingers with linear cutting edge, but no strong setae are observed. Ovigers are glabrous, with no simple spines as described for the male. The strigilis spine formula is 14:8:9:7 and the terminal claw has 18 teeth. The configuration of the propodus agrees totally with that of the
holotype
; the main claw is long, about ¾ the propodal length.
