Smeringopus natalensis Lawrence 1947: 14–15, figs. 7a–b. Lawrence 1967: 299, figs. 3–5. Huber 2001: 136, figs. 430, 432–433, 437.
Type. Male holotype from South Africa, KwaZulu Natal, Verulam [29°39’S, 31°03’E], date and collector not given, in Naturhistoriska Museet, Göteborg, Sweden, not examined.
Diagnosis. Distinguished from similar congeners (other species of the natalensis group, especially S. lesnei, S. florisbad, S. blyde, S. koppies, S. harare, S. badplaas) by shapes of bulbal processes (Figs. 302, 303); from other close relatives by absence of process near palpal tarsal organ (Fig. 300), relatively straight procursus (ventrally), absence of prolateral process on procursus tip, and three black lines ventrally on abdomen (versus two; compare Fig. 244 with Figs. 248 and 250).
Male (Badplaas, ZFMK). Total body length 6.3, carapace width 2.2. Leg 1: 53.6 (14.0 + 0.8 + 14.1 + 22.0 + 2.7), tibia 2: 9.6, tibia 3: 7.2, tibia 4: 10.0; tibia 1 L/d: 66. Habitus as in Figs. 243 and 244. Carapace ochre-yellow with distinct dark pattern (median, lateral, and submarginal marks), clypeus with pair of dark marks widened distally, sternum brown with light marks near leg coxae, legs with dark rings subdistally on femora and tibiae, abdomen dorsally with distinct dark pattern, ventrally with three dark lines in median part (median line narrow but distinct). Distance PME-PME 160 µm, diameter PME 170 µm, distance PME-ALE 70 µm, distance AME-AME 45 µm, diameter AME 135 µm. Ocular area slightly elevated, secondary eyes with very indistinct ‘pseudo-lenses’; deep thoracic pit. Chelicerae as in S. badplaas (cf. Figs. 314, 315), each apophysis with modified hair at tip (Fig. 345). Palps as in Figs. 256 and 257, coxa without retrolateral apophysis, trochanter barely modified, femur with retrolateral furrow with distinct rim proximally (Fig. 344), cymbium without projection near tarsal organ, procursus ventrally almost straight, without prolateral process at tip (Figs. 300, 301), bulb with three distinctively shaped processes (Figs. 302, 303). Legs without spines, few vertical hairs, with curved hairs on tibiae and metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 3.5%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots (Fig. 347); ALS with eight spigots each.
Variation. In males from Oudtshourn and from Tembe Elephant Park the median bulbal process is slightly shorter and thicker. Tibia 1 in 60 other males: 8.1–16.4 (mean 11.9).
Female. In general similar to male; tibia 1 in 87 females: 8.4–16.4 (mean 12.6). Epigynum a simple plate without pockets (Fig. 278), variable in shape and coloration and thus possibly not clearly distinguishable from close relatives (S. lesnei, S. florisbad, S. blyde, S. koppies, S. harare, S. badplaas); internal genitalia as in Figs. 279, 304, and 348 (also very similar to close relatives). The four females from Bloemfontein (see below) are assigned tentatively to S. natalensis rather than to S. florisbad because of the long legs (tibia 1: 12.7–15.6).
Note: This is a very rare case among Pholcidae where female legs are on average longer than male legs (Fig. 15) (cf. Huber 2005). The only other case known to me is Pholcus fragillimus but in that species sample size was much smaller (seven males, eight females; Huber 2011b).
Distribution. Widely distributed in eastern South Africa and southern Mozambique, ranging further west along the coast (Fig. 298).
