Smeringopus dundo new species

Figs. 584–585, 604–605, 679–685

Type. Male holotype from Angola, Luanda Norte Province, 6 km NW of Dundo [7°20’S, 20°47’E], 24.ix.1946 (A. de Barros Machado), in SMF (Ang 38.6) .

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

Diagnosis. Distinguished from similar congeners by tip of procursus (distinctive sclerotized and membranous elements; Figs. 679–681), shape of embolus (Figs. 682–684; distinctive dorsal view); from S. peregrinoides also by longer and more downward directed cheliceral apophyses (similar S. peregrinus; cf. Figs. 614, 615) and absence of v-shaped or u-shaped structure frontally in female internal genitalia (Fig. 604).

Male (holotype). Total body length 5.5, carapace width 1.8. Leg 1: 35.5 (9.6 + 0.8 + 9.1 + 14.0 + 2.0), tibia 2: 6.5, tibia 3: 4.9, tibia 4: 6.9; tibia 1 L/d: 47. Habitus similar S. moxico (cf. Fig. 569). Color pattern in general similar S. peregrinoides but rather indistinct (light colors apparently artificially darkened). Distance PME-PME 150 µm, diameter PME 140 µm, distance PME-ALE 60 µm, distance AME-AME 45 µm, diameter AME 140 µm. Ocular area slightly elevated, secondary eyes with ‘pseudo-lenses’; deep thoracic pit. Chelicerae with pair of distal apophyses as in S. peregrinus (cf. Figs. 614, 615). Palps as in Figs. 584 and 585, coxa with distinct retrolateral apophysis and shallow wide furrow, trochanter barely modified, femur with retrolateral furrow with distinct rim proximally, procursus with distinctive distal membranous and sclerotized elements (Figs. 679–681), bulb with distinctively shaped prolateral process on embolus (Figs. 682–684). Legs without spines, few vertical hairs, with curved hairs ventrally on tibiae and metatarsi 1 and 2, retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium present on tibia 1.

Variation. Tibia 1 in 4 other males: 9.1, 9.2, 9.2, 9.7.

Female. In general similar to male; tibia 1 in 7 females: 7.1–8.5 (mean 7.7). Epigynum a simple plate with pair of pockets about 1.5–2 pocket-diameters apart (Fig. 604); internal genitalia as in Figs. 605 and 685.

Distribution. Known from four localities in northeastern Angola and southern Congo D.R. (Fig. 608).
