“ Smeringopus elongatus ” (misidentification): Lessert 1930: 621–622, fig. 5.
Smeringopus lesserti Kraus 1957: 222–223, pl. 19, figs. 7–10 (except female from Dilolo-Gare; see below).
Types. Male holotype and 1♀ paratype from Congo D.R., Congo Central Province, Malela [5°59’S, 12°37’E], 2.–12.vii.1915 (H. Lang, American Museum Congo Expedition), in MHNG (only left male palp) [the SMF (40441) also has a palp of a “male paratype”, but a male paratype was not designated and the palp is also a left one]. One misidentified female paratype (poorly preserved, larger epigynal pockets) from Congo D.R, Lualaba Prov., Katanga, Dilolo-Gare [10°42’S, 22°20’E], 1931 (F. Haas), in SMF. All types examined.
Diagnosis. Easily distinguished from known congeners by long dorsal process on embolus (Figs. 380, 415), thin process distally on procursus (Figs. 402–404), and epigynum shape (small, narrow plate with relatively large semicircular pockets; Figs. 384, 423).
Male (Thysville). Total body length 6.5, carapace width 2.1. Leg 1: 64.3 (16.1 + 0.9 + 16.3 + 28.5 + 2.5), tibia 2: 10.5, tibia 3: 7.2, tibia 4: 10.5; tibia 1 L/d: 80. Habitus as in Figs. 374 and 375. Carapace ochre-yellow with brown median and lateral marks, clypeus with pair of brown stripes, sternum monochromous brown, legs ochreyellow to light brown, tips of femora and tibiae lighter, abdomen ochre-gray with distinct dorsal and ventral pattern. Distance PME-PME 185 µm, diameter PME 170 µm, distance PME-ALE 70 µm, distance AME-AME 40 µm, diameter AME 135 µm. Ocular area slightly elevated, secondary eyes with indistinct ‘pseudo-lenses’ (cf. female, Fig. 422); deep thoracic pit. Chelicerae as in Figs. 408 and 409, with small distal apophyses, each provided with modified hair (Figs. 416, 417). Palps as in Figs. 380 and 381, coxa with low retrolateral apophysis and deep wide furrow, trochanter barely modified, femur with deep retrolateral furrow with apophysis on proximal rim (Fig. 411), procursus with distinctive distal processes (Figs. 402–404, 412–413), bulb with long dorsal process arising from embolus (Figs. 405–407, 415). Legs without spines, few vertical hairs, with curved hairs on metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 2.5%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots (Fig. 418); ALS with eight spigots each (Fig. 419); PMS with two spigots each (Fig. 420).
Variation. Sternum varies from light brown to almost black; femora and tibiae subdistally often darkened. Tibia 1 in 34 males: 8.1–16.1 (mean 13.1).
Female. In general similar to male; tibia 1 in 51 females: 7.1–16.0 (mean 12.0). Epigynum small and narrow plate with relatively large, semicircular pockets (Figs. 384, 423); internal genitalia as in Figs. 385 and 410.
Distribution. Widely distributed in central Africa (Fig. 401).
