CEPHALOTHORAX: Carapace light yellow-brown, shiny, finely reticulate; radiating lines, margin suffused with gray; trident mark present. Sternum yellow-brown suffused with gray. Clypeus height 2. Chelicerae yellow with transverse dark band, not excavated; seta-tipped tubercles absent; promargin six teeth, retromargin five denticles. Cheliceral stridulatory organ ~18 striae, well spaced throughout. ABDOMEN: Uniformly dark gray. LEGS: Yellow, basal half of femurs darker; total length leg I: 2.88, total length leg III: 2.03; Tm I: 0.22, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis long and thin, smooth; dorsal tibial apophysis wide, with several pointed smooth tips; two retrolateral trichobothria and one dorsal ( Fig. 550 ). Cymbium rounded; glabrous depression absent ( Fig. 550 ); dorsal and ventral cymbial tubercles black, sharply pointed and smooth; prolateral notch shallow ( Fig. 551 ). Paracymbium apical pocket long, anterior pocket short, posterior pocket absent ( Fig. 550 ). Embolus tip rounded, broad; basally with large prong; Fickert’s gland absent; ventral lamella reduced or absent; thumb long, extending over the embolus proper ( Fig. 552 ). Embolus proper set apically on a vertical ridge, not associated with the embolus tip, ventral and dorsal part about equal ( Fig. 552 ). Anterior terminal apophysis large, with numerous, long protrusions and with associated large prong basally; posterior terminal apophysis large well sclerotized, pointed; lamella characteristica large, with one narrow transparent flagellum and a large rounded process with a sharp point ( Fig. 553 ). Female : Total length 1.60; carapace length 0.64, width 0.48. CEPHALOTHORAX: Coloration as in male. Chelicerae yellow with dark transverse band; promargin six teeth, retromargin five denticles. Cheliceral stridulatory organ ~15 striae, well spaced throughout. ABDOMEN: As in male. LEGS: Same coloration as male; palpal segments dark, claw absent; total length leg I: 2.69, total length leg III: 1.81; Tm I: 0.28, Tm IV: absent. GENITALIA: Female epigynum with two large, circular depressions ( Fig. 554 arrow); proximal part of scape narrow expanding apically; epigynal slits oval; pit hook depression indistiguishable ( Fig. 554 ); lateral lobes short but wide; stretcher small; pit small ( Fig. 555 ). Median part of scape short and wrinkled; genital pores situated at base of lateral lobes ( Fig. 556 ). Internal genitalia with elongated receptacula with basal bulge ( Fig. 555 ).
