General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
A large spider that weighed in at 0.58 grams, 20mm long.
You can see the hoof like brushed feet in the dorsal shot. Even their palps have brushed "feet".
Unlike most other spiders, these have their eyes very close together.
Mygalomorphs have 4 lungs, rather than 2 as in modern spiders. You can see them in the ventral shots as the light colours bulges on the abdomen.
We have only found male Mygalomorphs as they go out looking for a mate. The females generally stay hidden in their burrow.
We found this one male in July.
