Description

Male (Forêt d’Analalava, Madagascar, CASENT 9005869, CAS): Carapace with band of white setae around margin, longitudinal line in cephalic region and patches near PLE; cephalic region subtriangular, longer than wide, moderately raised; AME distinctly smaller than PME (AME/PME 0.62), median eyes separated on horizontal axis, largely overlapping on vertical axis; ALE on small tubercles; PER much narrower than AER (PER/AER 0.76), PLE position on carapace 0.32; clypeal hood forms acute angle; fovea shallow. Chelicerae with lateral boss, slightly excavated mesally. Legs with patches and longitudinal bands of white setae; leg I thickened with thick brush of dark setae on femur and especially tibia; with row of distal ventral macrosetae on metatarsus I–IV, a few scattered ventral macrosetae on tarsus I–IV and metatarsus II–IV. Dorsum of abdomen with median longitudinal stripe and posterior patch of white setae (Figs 11E, F, 84A–D).
Male palp with proximal-distal axis; tegulum subtrapezoidal; conductor and embolus together form apical complex making one helical turn; conductor with more or less membranous and papilliated inner layer extending beyond moderately sclerotized outer layer; embolic division longer than tegular division; cymbium with several prolateral macrosetae (Figs 15G–I, 84I, J, 85A–D).
Female (Forêt d’Analalava, Madagascar, CASENT 9005869, CAS):Carapace with band of white setae around margin, densely mixed in cephalic region, fewer in thoracic region mesal to lateral band; cephalic region subtrapezoidal, longer than wide, moderately raised; AME distinctly smaller than PME (AME/PME 0.69), median eyes separated on horizontal axis, largely overlapping on vertical axis; ALE on small tubercles; PER much narrower than AER (0.77), PLE position on carapace 0.27; clypeal hood forms acute angle; fovea shallow. Chelicerae contiguous mesally, with lateral boss. Legs with patches of white setae; with row of distal ventral macrosetae on metatarsus I–IV, scattered ventral macrosetae on tarsus I–IV and metatarsus II–IV. Dorsum of abdomen with alternating light and dark longitudinal bands (Figs 11G, H, 84E–H).
Epigynum bell-shaped with fleshy, bell-shaped median lobe, higher posteriorly than anteriorly, anteriomedian part with notch-shaped invagination (Figs 18H, 86A). Vulva with spermathecal heads on compact sinuous stalks leading to multilobed spermathecae posteriorly (Figs 18K, 86B–D).

Spinneret spigot morphology

Female ALS with 6–8 MAP within and on inner edge of spinning field of 40–80 or more PI (Fig. 87B; Griswold et al. 2005[8]: fig. 37B); male with 2 MAP and spinning field of more than 25 PI (Fig. 88B). Female PMS with 2 median mAP spigots, with posterior field of about 25 spigots of varying size and shape (Fig. 87C); male PMS with 1 median mAP and 12 AC (Fig. 88C); the large anterolateral spigot on the female may be a mAP or CY; other smaller spigots on the female may also be CY, though these cannot be differentiated morphologically (Fig. 87C). Female PLS with anterobasal MS with 2 accompanying AC spigots and distal field of 35–50 AC (Fig. 87D); male MS and flankers same, with about 18 AC (Fig. 88D, E). Male cribellar plate with no sign of spigots (Fig. 88F); numerous epiandrous gland spigots present (Fig. 85E, F). See also Griswold et al. (2005: 24–27, figs 34D–F, 25A–D, 36A–D, 37A–D).
