Two Interesting Crabs from Hawaii

Abstract

Crabs of the family Dynomenidae from precious coral beds off Oahu, Hawaiian Islands, are described as Dynomene devanryi sp. nov. The species is characterized by the velvetlike tomentum without long hairs, some transverse grooves on the dorsum and obtuse anterolateral teeth of the carapace, and the stout and nongranulated ambulatory legs. Another species from the same habitat is Cancer (Platepistoma) macrophthalmus (Rathbun, 1906) of the Cancridae. The recently erected subgenus Glebocarcinus is reduced to a synonym of Platepistoma, which hitherto has been known as a genus distinct from Cancer.
