Crinocheta

Belongs within: Oniscidea.
Contains: Armadillidae, Porcellio, Trachelopodidae, Oniscidae, Philosciidae.

The Crinocheta are a group of terrestrial isopods characterised by an ’embolophore’ type of male genitalia with the two vasa deferentia opening by separate pores on either side of the penis towards its apex (Hatch 1947, as Embolophora). They are divided between the Armadilloidea, in which the pleopods carry respiratory pseudotracheae, and the Oniscoidea in which such structures are absent. Members of the Oniscoidea include the Scyphacidae, littoral isopods in which the antennal flagellum is markedly more slender than the basal segments (Muchmore 1990).
