Diagnosis.
Females of
C
.
escheri
are very similar to the females of
Capheris oncka
Lawrence, 1927
as both share semi-circular epigynal plate and short basomedian septum, but can be separated from the latter species by copulatory openings with straight anterior rim (vs. semi-circular in
C. oncka
) (compare
Fig. 11G
with
Jocqué 2009
: fig. 173).
Supplementary description.
Female
(
holotype
) (
Figs 11A–F
) (partly after
Reimoser (1934))
. Body length 5.90. Carapace 3.00 long, 1.50 wide. Opisthosoma 2.90 long, 1.70 wide. Carapace yellowish brown, slightly domed, without deep concavity at level of fovea (
Fig. 11D
); endites, sternum yellowish red; legs reddish yellow with darker femora; dorsum of opisthosoma black with small yellow dots and dashes (
Fig. 11F
), with five pairs of large yellow patches in varying sizes and shapes (
Fig. 11F
), laterals with paired pale yellow bands of reeds and spots, venter pale yellow with rows of black bands and spots. ALE almost touching, separated from each other by less than their radius (
Figs 11B–C
); PER straight in dorsal view (
Fig. 11B
). Sternum finely wrinkled, shield-shaped, sparsely covered with long bristles, with anterolateral indentations accommodating posterior part of endites, with precoxal sclerites (
Fig. 11E
). Tarsi II–IV ventrolaterally with two rows of spinules.
Epigyne
(
Fig. 11G
). Epigynal plate sclerotized, semi-circular, with narrow basomedian septum. Copulatory openings narrow, slit-like, with straight, sclerotized anterior margins.
Male
. Unknown.

Justification of the transfer.
This species was originally placed under
Capheris
(
Reimoser 1934
)
.
Jocqué (2009)
erroneously transferred it to
Cydrela
, without proper justification. An examination of the
holotype
of this species showed that it has diagnostic features of
Capheris
species
including carapace without deep concavity at level of fovea, ALEs situated in front of AMEs, ALEs almost separated by their radius, straight PER, sternum with anterolateral indentations and precoxal sclerites, and very stout palps (
Figs. 11A–E
). Based on these observations, the transfer of
C
.
escheri
is fully justified.
