Justification of new synonymies. The holotypes of S. pholcicus and S. buehleri were both examined and found to be identical to specimens from all over the world. The type of Pholcus excavatus is lost and the description would fit almost any Smeringopus. However, it is likely that the specimen originated from the lower Congo rather than from the interior, and only four species are known to occur there. Of these, only S. pallidus and S. lesserti fit Simon’s (1877) description of the bulbal apophysis (“divisée dès la base en deux branches divergentes, arquées”), and since Simon did not mention the distinctive long spine at the tip of the procursus of S. lesserti (Fig. 380), I conclude that Ph. excavatus is most likely a synonym of S. pallidus.
Diagnosis. Easily distinguished from similar congeners (S. lineiventris and other species of the arambourgi species group) by tip of procursus (Figs. 387–389), shapes of bulbal processes (Figs. 390, 391), and epigynum shape (small oval to rectangular dark plate; Figs. 382, 399).
Male (Uganda, Bumaga). Total body length 5.3, carapace width 1.8. Leg 1: 47.0 (12.7 + 0.8 + 12.1 + 19.1 + 2.3), tibia 2: 8.1, tibia 3: 6.0, tibia 4: 8.4; tibia 1 L/d: 67. Habitus as in Figs. 372 and 373. Carapace ochre-yellow with brown median and lateral marks, clypeus with pair of dark stripes, sternum brown, legs ochre-yellow to light brown, femora and tibiae with dark subdistal rings and lighter tips, abdomen ochre-gray with distinct dorsal and ventral pattern. Distance PME-PME 160 µm, diameter PME 170 µm, distance PME-ALE 55 µm, distance AME-AME 35 µm, diameter AME 115 µm. Ocular area slightly elevated, secondary eyes with barely visible ‘pseudolenses’; deep thoracic pit. Chelicerae as in Fig. 392, with small distal apophyses. Palps as in Figs. 378 and 379, coxa with small but distinct retrolateral apophysis, trochanter barely modified, femur with wide retrolateral furrow, proximal rim slightly more distinct, cymbium with projection near tarsal organ, procursus with distinctive distal processes (Figs. 387–389, 394), bulb with sclerotized embolus and distinctive dorsal process (Figs. 390, 391). Legs without spines, few vertical hairs, with curved hairs ventrally on tibiae and metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 2.5%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots (Fig. 398); ALS with eight spigots each (cf. female; Fig. 396).
Variation. Tibia 1 in 26 males: 8.8–14.0 (mean 11.7). The S. pholcicus holotype is very pale and the right palp is missing; tibia 2: 6.4.
Female. In general similar to male; tibia 1 in 41 females: 8.3–13.3 (mean 11.0). Epigynum a simple, small oval to rectangular dark plate without pockets (Figs. 382, 399); internal genitalia as in Figs. 383, 393, and 400.
Distribution. Pantropical. In Africa, S. pallidus is widely distributed from Cape Verde to Madagascar and Mauritius, but is seems to be largely absent from southern and northeastern Africa (Fig. 386).
Material examined. Listed here are only the African countries from which I have seen material: Cape Verde, Senegal, The Gambia, Guinea, Sierra Leone, Ivory Coast, Ghana, Nigeria, Cameroon, Gabon, Central African Republic, Congo D.R., Burundi, Malawi, Uganda, Tanzania, Angola, Mozambique, South Africa, Madagascar, Comoros, Seychelles, Mascarene Islands.
