description
Description. Carapace yellowish brown (Figs 2 A – B, 4 A – B). Eye region black, with sparse white setae (Figs 4 B). Chelicerae yellowish brown, with three promarginal and two retromarginal teeth. Labium and endites yellowish brown, longer than wide. Sternum yellowish brown, heart-shaped, with sparse brown setae. Legs yellowish brown, with brown ring-like stripes. Opisthosoma oval. Dorsum yellowish brown, with lanceolate cardiac mark in anterior half and black irregular markings extending posteriorly. Dorsal patch of white setae present near the anal tubercle of males (Figs 2 C, 4 C). Venter of opisthosoma yellow, with short, yellow spinnerets. Male pedipalp. Median apophysis with three arms: fingernail-like anterior arm (AA), finger-like posterior arm (PA) and knife-like retrolateral arm (RA) (Figs 1 A – B, 2 D – G, 3, 4 D – E). Embolus long and slender, its anterior part resting in a long groove of a large and complex terminal apophysis (Figs 1 C, 2 H). Terminal apophysis with two arms, one of them membranous (TA 1), as the functional conductor (Piacentini & Grismado 2009), the other one sclerotized and groove-like (TA 2, Figs 1 C, 2 H). Epigyne. Copulatory openings arc-shaped. Septum broad, posteriorly projected (Figs 1 D, 2 I). Spermathecae rounded, with spermathecal head. Spermathecal stalk compact and sclerotized. Spermathecal head small, with round end. Fertilization ducts form crescents (Figs 1 E, 2 J). Composition. Two new species: S. damingshanensis sp. nov. and S. zhuangius sp. nov.
diagnosis
Diagnosis. The new genus is similar to Lobizon Piacentini & Grismado, 2009 in having a long embolus resting in a groove of a broad terminal apophysis, but differs from the latter by the sclerotized basoembolic apophysis (weakly sclerotized and lamellar in Lobizon), the presence of membranous terminal apophysis 1 (TA 1) and sclerotized, groove-like terminal apophysis 2 (TA 2) (TA 2 only in Lobizon), and three arms (AA, RA, PA) present in the median apophysis of male pedipalp (Figs 1 A – C, 2 D – H, 3, 4 D – E). Females can be recognized by the spermatheca that has a compact stalk and a small, protruding head (Figs 1 E, 2 J, stalk sinuous in Lobizon).
distribution
