Description

Male (7.5 km E PwintPhyu, Myanmar, CASENT 9019370, CAS): Carapace with few white setae, cephalic region subtriangular, longer than wide, moderately raised; AME nearly as large as PME (AME/PME 0.87), median eyes separated on horizontal axis, largely overlapping on vertical axis; ALE on small tubercles; PER much narrower than AER (PER/AER 0.86), PLE position on carapace 0.24; clypeal hood forms acute angle; fovea shallow. Chelicerae with lateral boss, slightly excavated mesally, with a single large keel-like tooth bearing denticles on the ectal side. Legs with numerous white setae; leg I somewhat thickened and elongated; with distal ventral macrosetae on tibia I–IV, row of distal ventral macrosetae on metatarsus I–IV plus scattered ventral macrosetae on metatarsus and tarsus I–IV. Abdomen with numerous white setae (Figs 11I, J, 89A–D).
Male palp with proximal-distal axis; cymbium slightly excavated retrobasally; conductor and embolus together form apical complex making more than one helical turn; conductor moderately sclerotized, tegular division longer than embolic division; cymbium with several prolateral macrosetae (Figs 15J–L, 89I, J, 90A–E).
Female (7.5 km E PwintPhyu, Myanmar, CASENT 9019370, CAS):Carapace with numerous white setae, cephalic region subtriangular, longer than wide, slightly raised; AME nearly as large as PME (AME/PME 0.84), median eyes separated on horizontal axis, largely overlapping on vertical axis; ALE on small tubercles; PER much narrower than AER (0.86), PLE position on carapace 0.24; clypeal hood forms acute angle; fovea shallow. Chelicerae contiguous mesally, with lateral boss. Legs with numerous white setae; with pair of distal ventral macrosetae on metatarsus I–IV, scattered ventral macrosetae on tibia III and metatarsus and tarsus III–IV. Abdomen with numerous white setae (Figs 11K, L, 89E–H, 91A, B, D, E).
Epigynum with slit-like atria that converge then briefly diverge near anterior limit, occupying nearly the total length, anteriomedian part with moderate notch-shaped invagination, anteriolateral margin a moderate curved ridge (Figs 18I, 93A). Vulva with spermathecal heads on long sinuous stalks leading to multilobed spermathecae posteriorly (Figs 18L, 93B–E).

Spinneret spigot morphology

Female ALS with at least 7 MAP within and on inner edge of spinning field of more the 90 PI and many small tartipores (Fig. 94B); male with at least 1 MAP on inner margin and 3 more within spinning field of about 50 PI (Fig. 95B). Female PMS with 1 central mAP spigot, a large anterior spigot (probably CY) flanked by 2 large tartipores, and 30 smaller spigots scattered from anterior to posterior (Fig. 94C); male PMS with 1 central mAP and about 9 AC, suggesting that the additional spigots on the female may comprise AC and CY spigots (Fig. 95C). Female PLS with anterobasal MS and 1 accompanying spigot and distal field of more than 35 AC (Fig. 94D); male MS with 2 flanking spigots, also with about 35 AC (Fig. 95D, E). Male cribellar plate with no sign of spigots (Fig. 95F); numerous epiandrous gland spigots present (Fig. 93F).
