Monobella grassei is a distinctive cream or pale orange species (Fig. 1) which fades to white in 70% alcohol. The body setae are obvious (Fig. 2) (although not as long as in Lathriopyga longiseta) and there are two ocelli on each side of the head (Fig. 3). Monobella grassei is probably widespread in Wales and southern England. An old record of this species for Ireland was based on a slide prepared by Bagnall in the Natural History Museum in London. However Steven examined this specimen and found it to be Anurida granaria. Peter Shaw has found this species the Whitelands college compost heap on both its old (Sutherland Grove) and new (Holybourne Ave) sites in London.
