Mistaria fagei (Caporiacco, 1949)  comb. n. Fig. 1

Synonym: Agelena fagei  Caporiacco, 1949 see Caporiacco (1949: 330, fig. 8, ♀) and Roewer (1955: 29, fig. 7, ♀).

Type material examined.

Lectotype, ♀, Kenya, Mau, January 1946, Meneghetti ( NMLS).

Diagnosis.

M. fagei  , M. leucopyga  and M. nairobii  all have a concave shaped sclerotised delimiting edge. M. fagei  can be distinguished from M. leucopyga  by the conspicous copulatory ducts (Fig. 1B). It can be separated from M. nairobii  by the shape of the spermathecae lobes which are rounded compared to ovoid in this species and by the absence of a septum in the latter species (Figs 1B, 3B).
