Smeringopina Cam  40: Dimitrov, Astrin & Huber 2013 (DNA data).

Type. ♂ holotype from Cameroon, Southwest Region, near Dschang, Attuleh  , “site 1 ” (5 ° 27.7 ’N, 9 ° 56.5 ’E), 1880 m a.s.l., near ground, 20.iv. 2009 (B.A. Huber), in ZFMK (Ar 10216).

Other material examined. CAMEROON: Southwest Region: near Dschang, Attuleh  , “site 1 ”, same data as holotype, 3 ♂ 2 ♀ in ZFMK (Ar 10217); same data, 1 ♀ 4 juvs. in pure ethanol, in ZFMK (Cam 126); Attuleh  , “site 2 ” (5 ° 27.9 ’N, 9 ° 56.5 ’E), 1800 m a.s.l., near ground, 20.iv. 2009 (B.A. & J.C. Huber), 4 ♀ in ZFMK (Ar 10218); same data, 3 ♀ in pure ethanol, in ZFMK (Cam 122). Near Dschang, Essotah  (5 ° 25.5 ’N, 9 ° 54.7 ’E), 1600 m a.s.l., near ground, 21.iv. 2009 (B.A. Huber), 2 ♂ 1 ♀ (2 vials) in ZFMK (Ar 10219 - 20); same data, 2 ♀ 3 juvs. in pure ethanol, in ZFMK (Cam 96).

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

Diagnosis. Distinguished from most congeners by distinctive male cheliceral armature (very densely packed modified hairs on distinctively shaped apophyses; Fig. 320View FIGURES 318 – 323) and procursus with ventral indentation occupied by complex membranous structures ( Fig. 319View FIGURES 318 – 323); from the very similar S. mbouda  by shorter male cheliceral apophyses ( Fig. 320View FIGURES 318 – 323), simple embolus ( Fig. 321View FIGURES 318 – 323), dorso-distal process on procursus ( Fig. 319View FIGURES 318 – 323), and anterior epigynal plate with distinct median process (in lateral view; Fig. 305View FIGURES 304 – 317) and more angular ventral edges (in ventral view; Fig. 322View FIGURES 318 – 323).

Male (holotype). Total body length 4.6, carapace width 1.5. Leg 1: 33.7 (8.1 + 0.5 + 8.1 + 14.9 + 2.1), tibia 2: 5.2, tibia 3: 3.8, tibia 4: 6.0; tibia 1 L/d: 55. Distance PME-PME 135 µm, diameter PME 140 µm, distance PME- ALE 70 µm, distance AME-AME 55 µm, diameter AME 125 µm. Carapace ochre with dark brown triangular mark posteriorly, brown mark behind ocular area, brown lateral margins; ocular area not darkened, clypeus with pair of indistinct bands below eyes, sternum brown; legs ochre-brown, darker rings subdistally on femora and tibiae and in patella area, tips of femora and tibiae lighter; abdomen ochre-gray with dark pattern dorsally, laterally, and ventrally. Habitus as in Figs. 294–295View FIGURES 294 – 303, ocular area slightly elevated, secondary eyes with indistinct ‘pseudolenses’; clypeus unmodified; deep thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 320View FIGURES 318 – 323, with lateral proximal apophyses connected to short rounded distal apophyses, the latter with ~ 25 large modified (cone-shaped) hairs on each side. Palps as in Figs. 296–298View FIGURES 294 – 303; coxa unmodified; trochanter with short conical retrolatero-ventral apophysis; femur with retrolateral flap and large whitish area ventrally, without prolateral modification; prolateral femur-patella joint strongly shifted toward ventrally (hidden by bulb in Fig. 296View FIGURES 294 – 303); tarsus with some longer but barely stronger hairs dorsally; procursus with ventral indentation occupied by complex membranous structures, without hinge, with dorso-distal process; bulb with simple small embolus with small sclerotized branch ( Fig. 321View FIGURES 318 – 323). 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 4 other males: 8.6, 8.6, 8.7, 9.5.

Female. In general similar to male. Tibia 1 in 7 females: 7.0– 7.8 (mean 7.4). Epigynum anterior plate trapezoidal ( Figs. 304View FIGURES 304 – 317, 322View FIGURES 318 – 323), with distinct median process ( Fig. 305View FIGURES 304 – 317) variable in shape even within localities (either rounded or with pair of small processes), posterior edges angular; large flat posterior plate; internal genitalia as in Figs. 306View FIGURES 304 – 317 and 323View FIGURES 318 – 323.

Natural history. S. attuleh  was found mainly under large dead leaves on the ground, but also in small cavities in the ground and under roots.

Distribution. Known from three neighboring localities in Cameroon, Southwest Region ( Fig. 293View FIGURE 293).
