Description

Mallomonas crassisquama (Asmund) Fott (Fig. 2K)

DISTRIBUTION. — Widely distributed (Kristiansen 2000).

REMARKS

This species is closely related to M. acaroides (initially it was described as M. acaroides var. crassisquama Asmund) but the shield of its scales is ornamented with a secondary layer of ribs that form a reticulum (Siver 1991). The most reliable, distinctive character between these two species is the presence of spine-bearing rear scales in M. crassisquama; such scales are not present in M.acaroides (Kristiansen 2002).
