Genus CLUBIONA, Latr.
Spiders usually of a yellowish or reddish yellow colour,
generally without distinct abdominal patterns, (C. compta and
C. corticalis are striking exceptions). The tibial apophysis of the
male is very variable in form. The epigynal armature of the
female is, as a rule, obscure, specimens of this sex being often
very difficult to identify specifically. The genus is well repre-
sented in Epping Forest, eight out of the fifteen British species
having been taken within its boundaries.
Clubiona terrestris, Westr.—Common over the whole of
of the Forest, including Edmonton Marshes. It is usually
found under debris and flood-refuse.
Clubiona grisea, L. Koch.—Males have occurred, but
rarely, in several localities.
Clubiona reclusa, Cb.—A male taken at Theydon Bois.
Clubiona corticalis, Walck.—Not uncommon at several
