59B3E539-C026-4CC3-81C9-C2CF148BD2F3
Figs 18–19
Diagnosis
The male differs from that of
Finger lechi
Wesołowska & Wiśniewski,
2023
in having a distinctly longer embolus surrounding the bulb, while the embolus in
F. lechi
does not form a loop around the bulb. The female has an epigyne somewhat similar to that in
Finger chitato
Wesołowska & Wiśniewski, 2023
but can be recognized by the shape of the epigynal depression, which is triangular in the newly described species, while
F. chitato
has a bipartite depression.
Etymology
The specific name is Latin, meaning ‘small’ and refers to size of this species.

Description
Male
General appearance as in
Fig. 18A
, very small spider.
MEASUREMENTS
. Cephalothorax length 1.6–1.8, width 1.2–1.4, height 0.6–0.7. Eye field length 0.8–0.9, anterior width 1.2–1.3, posterior width 1.1–1.2. Abdomen length 1.5–1.8, width 1.1–1.2.
CARAPACE
. Chocolate brown, eye field darker, anterior eyes encircled by white hairs (
Fig. 18B
). Carapace densely covered with white hairs, but some specimens hairless. Chelicerae dark brown, unidentate. Sternum dark, labium and endites light brown.
ABDOMEN
. Dorsally with mosaic of grey patches on light background, traces of central yellowish-brown streak, dark chevrons in posterior half, venter creamy. Posterior spinnerets grey, anterior creamy.
LEGS
. Brown with grey markings, first pair largest, brown (only tarsi yellow), long dark feather-shaped hairs on femur, patella and tibia ventrally (
Fig. 18C
).
PALPS
. Brown, clothed in brown and whitish hairs. Palpal tibia short with bent retrolateral apophysis at tibial base (
Figs 18D
,
19A
). Bulb rounded, embolus long, surrounding bulb (
Figs 18D
,
19A
), S-shaped in lateral view (
Figs 18F
,
19C
).
Female
General appearance as in
Fig. 18H
. Similar to male, lighter coloured.
MEASUREMENTS
. Cephalothorax length 1.5, width 1.1, height 0.6. Eye field length 0.8, anterior width 1.0, posterior width 0.9. Abdomen length 1.6, width 1.0.
EPIGYNE
. Very small, as in
Fig. 19D
, with wide triangular central depression. Copulatory ducts weakly sclerotized (visible after staining in Chlorasole black E), very wide in initial part, their course hard to follow (possibly damaged during preparation), spermathecae spherical (
Fig. 19E
).
Remarks
A closely related and still undescribed species occurs in
Gabon
(see
Bodner & Maddison 2012
: fig. 2b, MRB260).
