Type. ♂ holotype from Gabon, Estuaire, Monts de Cristal, between Tchimbélé  and Kinguélé  (0° 33.8 ’N, 10 ° 18.8 ’E), 520 m a.s.l., forest near river, 10.viii. 2011 (B.A. & S.R. Huber), in ZFMK (Ar 10190).

Other material examined. GABON: Estuaire: Monts de Cristal, between Tchimbélé  and Kinguélé  , same data as holotype, 2 ♂ 8 ♀ 3 juvs. in ZFMK (Ar 10191); same data, 1 ♀ 1 juv. in pure ethanol, in ZFMK (Gab 193).

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

Diagnosis. Smallest known Smeringopina  species (body length about 2.4 mm), easily distinguished from congeners by S-shaped procursus with fringed membranous processes ventrally ( Figs. 184–185View FIGURES 184 – 189), distinctive modification of clypeus (pair of slender, weakly sclerotized processes at rim), and by shape of epigynum (wide and short anterior plate, very large posterior plate; Figs. 163View FIGURES 163 – 183, 188View FIGURES 184 – 189).

Male (holotype). Total body length 2.4, carapace width 0.85. Leg 1: 17.1 (4.1 + 0.3 + 4.2 + 7.2 + 1.3), tibia 2: 2.5, tibia 3: 1.8, tibia 4: 3.0; tibia 1 L/d: 68. Distance PME-PME 95 µm, diameter PME 80 µm, distance PME-ALE 35 µm, distance AME-AME 35 µm, diameter AME 45 µm. Carapace ochre-yellow with brown posterior mark connected with brown mark posteriorly on ocular area, brown lateral margins; clypeus with light brown pattern, sternum dark brown; legs light brown, with small black marks (especially proximally on femora), tips of femora and tibiae whitish, no darker rings; abdomen ochre-gray with dark pattern dorsally, laterally, and ventrally, ventral dark bands without lateral constriction. Habitus as in Figs. 115–116View FIGURES 115 – 124, ocular area slightly elevated, secondary eyes with very indistinct ‘pseudo-lenses’; clypeus with pair of slender, weakly sclerotized processes at rim; shallow thoracic pit and pair of shallow furrows diverging behind pit. Chelicerae as in Fig. 186View FIGURES 184 – 189, with lateral apophyses in very distal position, with small frontal apophyses near tips of clypeus projections, without modified hairs. Palps as in Figs. 117–119View FIGURES 115 – 124; coxa unmodified; trochanter with strong ventral apophysis with sclerotized cones distally ( Fig. 242View FIGURES 232 – 245); femur with large retrolateral apophysis directed toward ventrally, without prolateral modification, with low weakly sclerotized ventral hump distally; prolateral femur-patella joint only slightly shifted toward ventrally; tarsus with some longer and slightly stronger hairs dorsally; procursus as in Figs. 184–185View FIGURES 184 – 189, S-shaped with fringed membranous processes ventrally, without hinge; bulb with slender sclerotized process arising from weakly sclerotized protrusion (sperm duct opens at basis of slender process; Figs. 187View FIGURES 184 – 189, 243View FIGURES 232 – 245). Legs without spines and curved hairs, with few vertical hairs; retrolateral trichobothrium on tibia 1 at 2 %; prolateral trichobothrium present on all tibiae; pseudosegments barely visible. ALS with seven spigots each; gonopore with two epiandrous spigots ( Fig. 240View FIGURES 232 – 245).

Variation. Tibia 1 in 2 other males: 4.7, 4.9.

Female. In general similar to male; clypeus unmodified. Tibia 1 in 8 females: 3.2–3.7 (mean 3.5). Epigynum anterior plate wide and short, with pair of indistinct small pockets about 300 µm apart ( Figs. 163View FIGURES 163 – 183, 188View FIGURES 184 – 189, 245View FIGURES 232 – 245); posterior plate relatively large, weakly curved; internal genitalia as in Figs. 173View FIGURES 163 – 183, 189View FIGURES 184 – 189, and 241. ALS with seven spigots each ( Fig. 244View FIGURES 232 – 245).

Natural history. Collected under dead leaves on the ground in a well preserved very humid forest near a river.

Distribution. Known from type locality only ( Fig. 114View FIGURE 114).
