Pleistacantha is a genus of crabs in the family Oregoniidae.[3] The genus occurs throughout many coasts in Europe, Africa, Asia, and Oceania.[2]
Description
[edit]Its carapace is pyriform and has a rostrum of two slender spines (sometimes with accessory spines); interantennular partition with a well developed, sometimes bifid, spine at its apex ventrally; carpus of cheliped with many spines or tubercles. Like Trichoplatus, Its supraorbital eave moderately produced, margin convex, smooth; propodi of all ambulatory legs flattened and strongly widened distally. [4]
Taxonomy
[edit]Pleistacantha was described by zoologist Edward J. Miers in 1879.[1] Its name is derived from the Greek roots pleistos (πλεῖστος), a superlative meaning "many", and acantha (άκανθα), meaning "spine".[1] In 2013, evidence that the family Inachoididae was not monophyletic prompted carcinologists to move Pleistacantha and several other genera into the family Oregoniidae.[5]
