Thomisidae Tarrocanus

"Tarrocanus" sp. "Cone-eyed"

Cone-eyed Crab Spider

This extremely rare and bizarre crab spider is provisionally placed in the genus Tarrocanus, characterised by a high and broad clypeus, horseshoe marking on the carapace, and grossly enlarged PLE tubercles. Each of the PLE tubercles of the Singapore female has a conical outgrowth. These are short structures pointing upwards, unlike those seen on the PLE tubercles of the female of T. capra, found in Sri Lanka, which are longer and droop downwards. (T. capra is designated the "type species" [page xxx] of the genus.) The Singapore female also differs from the T. capra female by having a a larger pleural membrane ("pleuron", green arrow) below the clypeus and folded over the upper parts of the chelicerae.
