, R.

MNHN
(
AR 10362
), mislabeled as “
Smeringopus fontisflorum
… Bloemfontein
…”.
The
actual type label was found in a vial containing
S. lesserti
from
Gabon
.
Diagnosis. Distinguished from similar congeners (other species of
arambourgi
species group and
S. pallidus
) by distinctively curved tip of procursus (
Figs. 185
,
205
), shapes of bulbal processes (hooked embolus and slender dorsal projection;
Figs. 207
,
211
), and epigynum shape (
Fig. 194
; externally similar
S. oromia
and
S. saruanle
).
Male (Nech Sar N.P., plains). Total body length 5.2, carapace width 1.7. Leg 1: 44.4 (11.3 + 0.7 + 11.5 + 18.8 + 2.1), tibia 2: 8.0, tibia 3: 5.9, tibia 4: 8.1; tibia 1 L/d: 63. Habitus as in
Fig. 169
. Carapace with distinct median and lateral brown marks, sternum brown with light spots, leg femora and tibiae with subdistal dark rings and light tips, abdomen pale grey, dorsally with distinct dark pattern, ventrally with three lines in median part (median line broken), with transversal mark in posterior third (cf. female,
Fig. 170
). Distance PME-PME 150 µm, diameter PME 150 µm, distance PME-ALE 55 µm, distance AME-AME 30 µm, diameter AME 125 µm. Ocular area slightly elevated, secondary eyes with indistinct ‘pseudo-lenses’ (
Fig. 215
); deep thoracic pit. Chelicerae as in
Fig. 208
, with small distal apophyses, each provided with one modified hair at tip (
Figs. 212, 213
). Palps as in
Figs. 184 and 185
, coxa without retrolateral apophysis, trochanter barely modified, femur with retrolateral furrow, proximal rim slightly more distinct, cymbium without projection near tarsal organ, procursus with distinctively curved tip and large prolateral process (
Figs. 205, 206
,
210
), bulb with sclerotized embolus and distinctive slender dorsal process (
Figs. 207
,
211
). Legs without spines, few vertical hairs, with curved hairs on metatarsi 1–2, retrolateral trichobothrium on tibia 1 at 3.5%; prolateral trichobothrium present on tibia 1. ALS with eight spigots each (
Fig. 214
).
Variation. Some males with considerably less dark pattern (e.g. without lateral marks on carapace, fewer ventral abdominal marks, median ventral line sometimes missing). Tibia
1 in
syntypes
: 15.2, 15.9;
2 males
from Sof Omar: 13.7, 18.0; male from
Somalia
: 10.0. The
syntypes
are in fairly good condition; in
one male
both palps are detached and one of them is missing.
Female. In general similar to male; tibia
1 in
7 females
: 10.4–16.2 (mean 13.8). Epigynum a simple flat plate without pockets, internal structures visible through cuticle (
Fig. 194
); internal genitalia as in
Figs. 195
,
209
, and 217. ALS as in male (
Fig. 216
).
Distribution. Known from three localities in southern
Ethiopia
and from
Somalia
(locality unknown) (
Fig. 204
).
