Figs. 702–704, 707–708 View FIGURES 699–708 , 725–728, 741–744

Type. Male holotype from São Tomé and Príncipe, Príncipe Island, forest on road to Sundi Plantation , 3.55 air km NW Santo Antonio de Príncipe (1°39.6’N, 7°23.7’E), 195 m a.s.l., sifting leaf litter, 21.iv.2001 (C.E. Griswold), in CAS GoogleMaps   .

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

Diagnosis. Distinguished from similar congeners (other species of the thomensis   species group) by dorsal projection on procursus tip ( Figs. 725 View FIGURES 725–731 , 742 View FIGURES 732–744 ) and much wider pore plates ( Figs. 728 View FIGURES 725–731 , 743 View FIGURES 732–744 ); also by shape of embolus (only one rounded apophyses arising from embolus; Figs. 726, 727 View FIGURES 725–731 ; similar S. mayombe   ); from S. thomensis   also by pair of sclerotized areas on posterior rim of epigynum ( Fig. 712 View FIGURES 709–717 ). Easily distinguished from all other congeners by distinctive color pattern dorsally on abdomen (figure composed of three black elements on posterior half; in Fig. 703 View FIGURES 699–708 the frontal part of this figure appears fragmented).

Male (holotype). Total body length 5.8, carapace width 1.9. Leg 1: 51.7 (14.0 + 0.8 + 12.4 + 21.7 + 2.8), tibia 2: 9.5, tibia 3: 6.8, tibia 4: 9.1; tibia 1 L/d: 54. Habitus as in Fig. 703 View FIGURES 699–708 . Carapace ochre-yellow with median dark mark restricted to frontal part, wide lateral marks, clypeus distal half darker, with pair of lines also restricted to distal half, sternum dark brown with 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 175 µm, distance PME-ALE 70 µm, distance AME-AME 45 µm, diameter AME 135 µm. Ocular area slightly elevated, secondary eyes with small dark ‘pseudo-lenses’; deep thoracic pit. Chelicerae with pair of small distal apophyses as in S. thomensis   (cf. Fig. 721 View FIGURES 719–724 ). Palps as in Figs. 707 and 708 View FIGURES 699–708 , coxa with distinct retrolateral apophysis, trochanter barely modified, femur with deep retrolateral furrow, proximal rim distinct, procursus with distinctive distal structures including semitransparent dorsal process ( Figs. 725 View FIGURES 725–731 , 742 View FIGURES 732–744 ), bulb with sclerotized embolus with one rounded dorsal process ( Figs. 726, 727 View FIGURES 725–731 , 741 View FIGURES 732–744 ). Legs without spines, few vertical hairs, without curved hairs, retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium present on tibia 1.

Variation. Tibia 1 in 6 other males: 11.1–12.4 (mean 11.9).

Female. In general similar to male; tibia 1 in 3 females: 9.5, 10.7, 11.2. Epigynum a simple, roughly triangular plate with pair of pockets and pair of sclerotized areas on posterior rim, with distinct transversal internal structure visible through cuticle, posterior plate semicircular ( Figs. 712, 713 View FIGURES 709–717 ); internal genitalia as in Figs. 714 View FIGURES 709–717 and 728 View FIGURES 725–731 .

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