Arcania quinquespinosa [Status Unaccepted]   Alcock and Anderson,  1894 (Crab)
Organism information awaits expert curation
Class: Malacostraca

Margins of carapace armed with five spines, of which the two lateral and one intestinal are very long, 2 smaller. Carapace marked with a large red mark on the posterior surface.

The carapace is broadly conical, owing to the bulging, obliquely backwards of the branchial regions. The front is sharply bidentate, instead of bilobular. The large spines of the margins of the carapace are relatively smaller, and the spine on the postero-lateral border, on either side, is either altogether wanting or is represented only by a granule. The regions of the carapace, with the single exception of the boundary between the gastric and cardiac regions, are distinctly delimited by fine grooves, The fingers are nearly twice the length of the hand. The cardiac region in life shows as a large bright red milk-white edged ocellus. The rest of the carapace is delicate pink in life.

It is much smaller species, the carapace of the adult being less than 12 millimeter long, and less than 14 millimeter broad.
