The female epigynum
of the genus Hemicloea have a peculiar, folded scapus, which expands during copulation.
The original description mentions 3 males and 2 females and the epigynum
is dissected from the female, an additional label mentions "see slide 20, Smokies, Sept 18, 1937" but the slide and other specimens in the type series are missing.
He also mentions a clear abdominal pattern, light venter, and an epigynum
as in Hogna helluo (Walckenaer 1837).
Walking by the prosoma and chelicerae of the unaggressive female, the male moved towards the eunuch, now protecting the female epigynum
on her venter (Fig.
Described by de Blauwe (1973) but dorsal view of epigynum
was neither illustrated nor described.
viridans females, as he found that the two openings of a mated female's epigynum
were usually plugged with a hard, black material, often with the two-pronged distal portion of the paracybium of a male palpus inserted in each opening and embedded in the material.
italiense can be easily differentiated from T uhligi, whose copulatory ducts unite before opening in the center of the epigynum
Opisthosoma with dorsal colour patch, framed black and white; epigynum
with two large medial depressions (Figs.
3); uniformly yellow-brown to dark grey; cephalic area gradually sloping laterally; row of AE recurved to slightly procurved; PME never more than half their diameter apart; leg formula IV > I > II > III; male pedipalp without articulated tegular apophysis; lateral apophysis present; embolus a thin, curved spine and mostly covered by tegulum in ventral view; epigynum
variable, often protruding scape-like posteriorly.
Toca may be related to Caloctenus and Gephyroctenus, with which it shares scales on the abdominal dorsum and epigynum
as a single, slightly sclerotized fold (Silva 2003, 2004; Polotow & Brescovit 2008).
Several morphological features of this specimen are unusual, including a large number of ventral macrosetae on legs I and II, prominent sparse rows of elongate setae on the dorsum, a multi-cusped retromarginal tooth, and an epigynum
which superficially looks like an euophryine, but structurally is quite different.
poorly sclerotized and semi-transparent in most species, often with an anterior hood and centrally or anteriorly located COs.
