Smeringopina Cam 31: Dimitrov, Astrin & Huber 2013 (DNA data).

Type. ♂ holotype from Cameroon, Southwest Region, Mt. Koupé above Nyasoso (4°49.6’N, 9°41.1’E), ~ 1600 m a.s.l., near ground, 23.iv.2009 (B.A. Huber), in ZFMK (Ar 10252).

Other material examined. CAMEROON: Southwest Region: Mt. Koupé above Nyasoso , same data as holotype, 22.–23.iv.2009, 5♂ 7♀ 3 juvs. (5 vials) in ZFMK (Ar 10253-57); same data, 7♀ 8 juvs. (2 vials) in pure ethanol, in ZFMK (Cam 94, 147).

Etymology. The name is a noun in apposition, derived from the type locality.

Diagnosis. Distinguished from most congeners by horns in male ocular area ( Fig. 415 View FIGURES 411 – 415 ) and male clypeus with many small modified (globular) hairs on low humps near rim (cf. S. cornigera , Fig. 445 View FIGURES 445 – 455 ); from the very similar S. cornigera and S. kala by shape of procursus (wide, with pointed posterior process; Figs. 456–457 View FIGURES 456 – 461 ); females may be externally indistinguishable from those of S. cornigera and S. kala but the anterior epigynal process is apparently larger than in S. cornigera (note small sample sizes) and the position and shape of pore plates is significantly different from S. kala (compare Figs. 461 View FIGURES 456 – 461 and 467 View FIGURES 462 – 467 ).

Male (holotype). Total body length 4.4, carapace width 1.5. Leg 1: 10.5 + 0.5 + 10.8, metatarsus broken, tibia 2: 6.7, tibia 3: 4.7, tibia 4: 7.1; tibia 1 L/d: 87. Distance PME-PME 220 µm, diameter PME 150 µm, distance PME- ALE 105 µm, distance AME-AME 35 µm, diameter AME 135 µm. Carapace light brown with dark brown triangular mark posteriorly, brown pit and brown lateral margins; ocular area not darkened, clypeus with dark brown lateral margins and pair of dark bands below eyes, sternum brown; legs light brown, darker rings subdistally on femora and tibiae and in patella area, tips of femora and tibiae whitish; abdomen ochre-gray with dark pattern dorsally, laterally, and ventrally. Habitus as in Figs. 406–407 View FIGURES 401 – 410 , ocular area slightly elevated, each triad on additional hump, with two pairs of horns, one long and pointed above ALE, the other short, blunt and slightly more median, ‘pseudo-lenses’ only visible at PME; clypeus with pair of low humps near rim, each with ~15 small modified (globular) hairs, with distinct depression between humps; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 459 View FIGURES 456 – 461 , with lateral proximal apophyses and short distal apophyses directed toward frontally, the latter and frontal cheliceral face with ~15 small modified (globular) hairs on each side. Palps as in Figs. 408–410 View FIGURES 401 – 410 ; coxa with retrolateral apophysis; trochanter with small ventral apophysis; femur with weakly sclerotized retrolateral flap and large whitish area ventrally, without prolateral modification; prolateral femurpatella joint only slightly shifted toward ventrally; tarsus with some longer but only slightly stronger hairs dorsally; procursus short and wide in lateral view, with pointed posterior process, without hinge, with many hairs on retrolateral face and pointed membranous process on prolateral side ( Figs. 456–457 View FIGURES 456 – 461 ); bulb with simple small embolus with small pointed process ( Fig. 458 View FIGURES 456 – 461 ). Legs without spines and curved hairs, with few vertical hairs, retrolateral trichobothrium on tibia 1 at 1.5%; prolateral trichobothrium present on all tibiae; pseudosegments barely visible.

Variation. Tibia 1 in 5 other males: 9.3–11.1 (mean 10.6).

Female. In general similar to male; clypeus unmodified; ocular area with one pair of low humps above ALE. Tibia 1 in 7 females: 7.0–8.3 (mean 7.9). Epigynum anterior plate trapezoidal, with distinct anterior process, lateral edges drawn backwards ( Figs. 422 View FIGURES 416 – 426 , 460 View FIGURES 456 – 461 ); large flat posterior plate; internal genitalia as in Figs. 425 View FIGURES 416 – 426 and 461 View FIGURES 456 – 461 .

Natural history. S. nyasoso was mainly found under leaves that were curved in a way to provide protected space between leaf and soil, but also in little cavities in the ground near a brook.

Distribution. Known from type locality only ( Fig. 390 View FIGURE 390 ).
