Type.

holotype
from
Ethiopia
,
Oromia Region
,
Lake Langano
[~

], under stones, short grass near hotel,
24.x.1982
(
A. Russell-Smith
), in
ZFMK
(
Ar 8552
)
.
Etymology. The name is a noun in apposition, derived from the
type
locality.
Diagnosis. Distinguished from similar congeners (other species of the
arambourgi
species group and
S. pallidus
) by tip of procursus (
Figs. 225–227
), shapes of bulbal processes (
Figs. 228, 229
; simple semitransparent dorsal projection shorter and wider than in
S. arambourgi
), and epigynum shape (
Fig. 198
; similar
S. arambourgi
and
S. saruanle
).
Male (
holotype
). Total body length 3.6, carapace width 1.5. Leg 1: 23.9 (6.1 + 0.6 + 6.1 + 9.7 + 1.4), tibia 2: 4.2, tibia 3: 3.2, tibia 4: 4.8; tibia 1 L/d: 43. Habitus as in
Figs. 173 and 174
. Carapace with narrow median and lateral marks, clypeus with pair of dark marks, sternum light brown with darker margins and darker frontal half, legs monochromous ochre-yellow, abdomen ochre-gray with dark dorsal and ventral pattern. Distance PME-PME 135 µm, diameter PME 105 µm, distance PME-ALE 55 µm, distance AME-AME 45 µm, diameter AME 90 µm. Ocular area slightly elevated, secondary eyes with barely visible ‘pseudo-lenses’; deep thoracic pit. Chelicerae very similar
S. saruanle
(cf.
Fig. 236
), with pair of small distal apophyses. Palps as in
Figs. 188 and 189
, coxa without retrolateral apophysis, trochanter barely modified, femur with shallow retrolateral furrow, cymbium with small projection near tarsal organ, procursus with distinctive tip (
Figs. 225–227
), bulb with sclerotized embolus and simple semitransparent dorsal process (
Figs. 228, 229
). Legs without spines, few vertical hairs, with curved hairs on metatarsi 1–2 (many hairs missing), retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium present on tibia 1.
Variation. Ventral abdominal pattern in other male indistinct and irregular (artifact?); tibia
1 in
this male: 7.5.
Female. In general similar to male but both females with very distinct dark subdistal rings on femora and tibiae; tibia
1 in
2 females
: 5.6, 6.4. Epigynum a simple flat plate without pockets, lateral whitish areas separated from median part by black marks, posterior part without or with very indistinct darker areas (
Fig. 198
); internal genitalia as in
Figs. 199
and
230
.
Distribution. Known from two localities in central and northern
Ethiopia
(
Fig. 204
).
