Corasoides

Fauna Portal Genus Number: 2566

(after Humphrey 2017): Within Wheeler’s Porteriinae, Corasoides can be distinguished behaviourally from Nanocambridgea, Cambridgea and Baiami by its web structure and mode of moving on the upper surface of the platform. Morphologically Corasoides can be separated from these genera by the distinct abdominal pattern: pseudo-feathery hairs; more retromarginal than promarginal cheliceral teeth; male pedipalp with acutely bent and spine-like retrolateral tibial apophysis and a bristled retroventral apophysis. Simon’s description of Porteria is inadequate and this genus is currently under study (Merrill, 2014; unpublished thesis). Wheeler has described Corasoides as appearing as a giant version of Porteria. Until further details are available, Corasoides can be distinguished from Porteria by the presence in most species of three (sometimes two), rather than four tibial processes and the absence of notches on the trochanter.
