Description. Both sexes. Head shape and chaetotaxy as in Fig. 10 View FIGURES 10–14 . Lateral margins of preantennal area convex, frons rounded to slightly flattened; marginal carina slender; dorsal preantennal suture reaches dsms but does not extend much towards ads, and does not reach lateral margins of head; ventral anterior plate small, rounded triangular; coni short; temples rounded; gular plate rounded laterally with median point ( Fig. 10 View FIGURES 10–14 ). Thoracic and abdominal segments as in Figs 8–9 View FIGURES 8–9 .

Male. Thoracic and abdominal chaetotaxy as in Fig. 8 View FIGURES 8–9 ; aps present on tergopleurites IV–VII. Genitalia as in Figs 11–13 View FIGURES 10–14 : basal apodeme roughly rectangular, not much constricted at mid-length, with rounded anterior end ( Fig. 11 View FIGURES 10–14 ). Proximal mesosome square; ventral sclerite with slender anterior end, not reaching proximal margin of mesosome; mesosomal lobes anteriorly angular; rugose nodi extensive; 2 ames sensilla on each side near anterolateral corner of mesosomal lobes; 2 pmes sensilla on each side of gonopore, near rugose nodi; gonopore oval, with slender marginal thickening ( Fig. 12 View FIGURES 10–14 ). Parameral heads as in Fig. 13 View FIGURES 10–14 . Parameral blades tapering only distal to mesosome ( Figs 11, 13 View FIGURES 10–14 ).

Subgenital plate roughly square anteriorly+, with slight lateral submarginal bulges ( Fig. 14 View FIGURES 10–14 ); vulval margin gently rounded, somewhat flattened medianly, with 2–4 short, slender vms on each side and 5–6 short, thorn-like vss on each side; 4–7 short, slender vos on each side; distal 1 vos near vss ( Fig. 14 View FIGURES 10–14 ).
