Smeringopus thomensis Simon 1907: 251–252 .

Type. Male holotype from São Tomé and Principe, São Tomé Island, Ribeira Palma [0°21’N, 6°35’E], leg. L. Fea, possibly in Museo Civico di Storia Naturale "Giacomo Doria", Genova, not examined GoogleMaps .

Diagnosis. Distinguished from similar congeners (other species of the thomensis species group) by shape of embolus (two large rounded apophyses arising from embolus dorsally; Figs. 722, 723 View FIGURES 719–724 ) and absence of pair of sclerotized areas on posterior rim of epigynum ( Fig. 709 View FIGURES 709–717 ); from S. principe also by absence of dorsal projection from procursus tip (compare Figs. 720 View FIGURES 719–724 and 725 View FIGURES 725–731 ) and much narrower pore plate (compare Figs. 724 View FIGURES 719–724 and 728 View FIGURES 725–731 ). Easily distinguished from all other congeners by distinctive color pattern dorsally on abdomen (figure composed of three black elements on posterior half; Fig. 699 View FIGURES 699–708 ).

Male (Palha Plantation). Total body length 5.0, carapace width 1.5. Leg 1: 45.3 (11.9 + 0.5 + 10.8 + 20.1 + 2.0), tibia 2: 7.2, tibia 3: 5.1, tibia 4: 7.2; tibia 1 L/d: 64. Habitus as in Fig. 699 View FIGURES 699–708 . Carapace ochre-yellow with median and lateral dark pattern, clypeus distal half darker, without pair of lines, sternum dark brown with some small light spots, legs ochre-yellow, femora and tibiae with dark subdistal rings and light tips, abdomen grey with distinctive dorsal pattern, ventrally with dark anterior and posterior plates and three indistinct bands in median section. Distance PME-PME 125 µm, diameter PME 150 µm, distance PME-ALE 55 µm, distance AME-AME 30 µm, diameter AME 120 µm. Ocular area slightly elevated, secondary eyes with small dark ‘pseudo-lenses’; deep thoracic pit. Chelicerae with pair of small distal apophyses ( Fig. 721 View FIGURES 719–724 ), each provided with one modified hair at tip ( Fig. 734 View FIGURES 732–744 ). Palps as in Figs. 705 and 706 View FIGURES 699–708 , coxa with distinct retrolateral apophysis, trochanter barely modified, femur with deep retrolateral furrow, proximal rim distinct ( Fig. 732 View FIGURES 732–744 ), procursus with distinctive distal processes ( Figs. 719, 720 View FIGURES 719–724 ), bulb with complex embolus with distinctive rounded dorsal processes ( Figs. 722, 723 View FIGURES 719–724 ). Legs without spines, few vertical hairs, without curved hairs, retrolateral trichobothrium on tibia 1 at 2%; prolateral trichobothrium present on tibia 1. Gonopore with two epiandrous spigots ( Fig. 736 View FIGURES 732–744 ); ALS with one widened and one pointed spigot each, other spigots apparently reduced to two tiny remnants (cf. female, Fig. 737 View FIGURES 732–744 ).

Variation. Tibia 1 in 3 other males: 8.9, 10.1, 10.7.

Female. In general similar to male; tibia 1 in 5 females: 8.4–9.7 (mean 9.1). Epigynum a simple, roughly triangular plate with pockets ( Figs. 709, 710 View FIGURES 709–717 ), posterior plate semicircular; internal genitalia as in Figs. 711 View FIGURES 709–717 , 724 View FIGURES 719–724 , and 739.

Distribution. Known from São Tomé Island only ( Fig. 718 View FIGURE 718 ).

Material examined. SÃO TOMÉ AND PRÍNCIPE: São Tomé: Palha Plantation near São Tomé town (0°18.8’N, 6°42.4’E), 12.iv.2001 (C.E. Griswold), 4♂ 5♀ in CAS GoogleMaps . Ponta Barro Bóró (0°23.8’N, 6°36.3’E), in culvert along roadside, 27.iv.2001 (J.M. Ledford), 1♀ 3 juvs in CAS GoogleMaps . Augustino Neto, Rio de Oro Plantation (0°21.9’N, 6°38.7’E), 220 m a.s.l., 13.iv.2001 (C.E. Griswold), 1♀ in CAS GoogleMaps . São Tomé, no further locality data, 1.xi.1999 (W. Tavernier), 1♂ 1 juv. in MRAC (209235) ; same data but garden, 17.xi.1999, 1♂ 1 juv. in MRAC (209256).
