Note
.
Filistata polita
was synonymized with
Filistatoides insignis
by
Alayón (1972)
, who not examined the
types
. We examined the
types
of
Filistatoides insignis
and compared them with the
types
of
F. polita
Franganillo (1936, fig. 16)
that were recently located in the IES collection. The male palps, of
Filistata polita
types
resemble those of
Filistatoides insignis
by the presence of the cylindrical palpal tibiae without a dorsal-retrolateral projection, which is diagnostic to the genus
Filistatoides
; but can be distinguished by its strongly curved embolus (
Figs 3C‒D
,
6C
,
8E‒F
) with many projections on the tip (
Fig. 6E‒H
). Moreover, additional material examined from several Cuban localities provided only specimens assignable to
Filistata polita
which seems to be endemic to this island. Therefore, we are revalidating this species and transferring it to
Filistatoides
.

Diagnosis
.
Filistatoides polita
can be distinguished from other species by the strongly curved embolus (
Figs 3C‒D
,
6C
,
8E‒F
) with many projections on the tip (
Fig. 6E‒H
). Females can be distinguished by the elongate base of the spermathecae with thicker necks than in other species (
Figs 3E
,
8G
).
Description.
Male (Santiago de
Cuba
, Dos Caminos de San Luis, IBSP 166704). Carapace yellow, with lateral margins, ocular area and posterior eye area black. Chelicerae orange. Labium and endites yellow, sternum white. Legs yellow with sparse black stripes. Abdomen dorsally white with 6–7 black chevrons (
Fig. 3A
). Total length 3.5. Carapace length 1.4, width 1.0. PME separated by almost half their diameter. Palp measurements: femur 1.0 long, patella 0.4 long, tibia 0.7 long, 0.3 wide.
