“ Smeringopus peregrinus ” (misidentifications): Strand 1913: 341–343. Lessert 1915: 5–6, pl. 1, fig. 3.
Smeringopus peregrinoides Kraus 1957: 224–225, figs. 17–22.
Types. Male holotype and 4♂ paratypes from Rwanda, no further data, in SMF (holotype: RII 7771; paratypes: RII 11726); 4♂ and several juvenile paratypes from “Bukoba, Njarugenji” [Tanzania: Kagera Region: Karagwe Distr.: Bukoba: 1°19’S, 31°48’E; Rwanda: Nyarugenge = Kigali: 1°57’S, 30°04’E], no date (J. Carl), in MHNG; 2♀ paratypes from Tanzania, Bukoba, no date (J. Carl), in SMF (9812/1) and MHNG, all types examined.
Misidentified type specimens: 3♀ paratypes from Angola, Huíla, Vila da Ponte [=Capelongo, 14°28’S, 16°18’E], no date (Exped. Monard), in MHNG (2♀) and SMF (9808/1: 1♀), examined.
Notes. Most of Lessert’s (1915) specimens from Bukoba and Nyarugenge are apparently joined in one vial. In contrast to Kraus (1957), this vial does not contain 4♂ 4♀ but only 4♂ and several juveniles. Two females are in separate vials (see above); the other two females could not be located. The identity of the misidentified females from Vila da Ponte remains unclear. They probably belong to an undescribed species.
Diagnosis. Distinguished from similar congeners by small perpendicular apophyses frontally on male chelicerae (Figs. 631, 632), by tip of procursus (distinctive prolateral sclerite; arrow in Fig. 627), shape of embolus (Figs. 628–630), and v-shaped (or u-shaped) structure frontally in female internal genitalia (visible through cuticle; Fig. 594).
Male (Akagera Parc). Total body length 6.6, carapace width 2.1. Leg 1: 36.9 (10.2 + 0.8 + 9.7 + 13.9 + 2.3), tibia 2: 7.2, tibia 3: 5.3, tibia 4: 7.5; tibia 1 L/d: 42. Habitus as in female (cf. Fig. 560). Carapace ochre-yellow with brown median and lateral marks, clypeus with pair of dark stripes, sternum brown with light marks near bases of coxae 2–4 and medially, legs light brown, femora and tibiae with lighter tips and subdistal dark rings, abdomen ochre-gray with distinct dorsal and ventral pattern. Distance PME-PME 175 µm, diameter PME 140 µm, distance PME-ALE 70 µm, distance AME-AME 60 µm, diameter AME 130 µm. Ocular area slightly elevated, secondary eyes with ‘pseudo-lenses’ (Fig. 638); deep thoracic pit. Chelicerae as in Figs. 631 and 632, with distinctively small distal apophyses, each provided with one modified hair at tip (Figs. 641, 642). Palps as in Figs. 574 and 575, coxa with distinct retrolateral apophysis and shallow wide furrow, trochanter barely modified, femur with retrolateral furrow with distinct rim proximally, procursus with distinctive prolateral sclerite distally (Fig. 627), without prolateral membranous projection, bulb with distinctively shaped prolateral process on embolus (Figs. 628–630). Legs without spines, few vertical hairs, with curved hairs on tibiae (ventrally) and metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium present on tibia 1 (Fig. 644). Gonopore with two epiandrous spigots (Fig. 640); ALS with eight spigots each (Fig. 643).
Variation. There is slight variation in the shape of the dorsal part of the process of the embolus (arrow in Fig. 629). This part is slightly wider in the Kenyan specimens, and slightly more projecting in specimens from Bujumbura (Burundi) and some specimens from Uganda. Kenyan specimens also lack the small pointed process ventrally on the embolus. Tibia 1 in 57 males: 6.0–14.9 (mean 10.7). The holotype is pale but otherwise in fair condition; tibia 1: 14.0.
Female. In general similar to male; tibia 1 in 52 females: 6.2–13.1 (mean 9.2). Epigynum roughly triangular, with distinctive internal structure frontally (v-shaped or u-shaped), and semicircular pockets (Figs. 594, 645); internal genitalia as in Figs. 595 and 633. ALS as in male (Fig. 646).
Distribution. Widely distributed in northeastern Congo D.R., Uganda, Rwanda, Burundi, northern Tanzania, and western Kenya (Fig. 608).
