Diagnosis.
Males of
V. fugiens
(O. Pickard- Cambridge)
comb. nov.
are distinguished from those of the remaining
Vindullus
species, except
V. guatemalensis
(Keyserling)
comb. nov.
, in having palps with a loosely spiraled tegulum, a triangular projection at the base of the embolus, a long, laminar serrated projection and a prolateral spiny field (
Figs 1–3
). They are distinguished from
V. guatemalensis
by the presence of a laminar, rounded, hyaline conductor (absent in
V. guatemalensis
) and by the small spiny field, restricted to the prolateral surface of the tegulum (extending ventrally in
V. guatemalensis
,
Figs 4–6
). Females are unknown.
