Diagnosis. The structure of the male pedipalp is very similar to that of some other Thyenula spp.  The male may be distinguished by the coloration of the abdomen (presence of a light transverse band in the posterior part) and by the light coloration of the basal palpal segments. The female is recognizable by the structure of the epigyne which has a unique narrow curved epigynal depressions and the longest spermathecae in the genus.

Etymology. The specific name is derived from the Latin for light and mark, referring to the presence of light bands on the abdomen of the male.

Description. Measurements (male/female). Cephalothorax: length 2.1–2.3/2.2–2.3, width 1.5–1.8/1.6–1.7, height 1.0/1.0. Abdomen: length 1.9–2.0/2.3–2.5, width 1.4–1.5/1.4–1.5. Eye field: length 0.9–1.1/1.0–1.1, anterior width 1.4–1.7/1.4–1.5, posterior width 1.3–1.6/1.4–1.5.

Male. General appearance as in Fig. 189View FIGURES 189–194. Carapace moderately high, sloping abruptly posteriorly, dark brown with shiny black eye field. Blackish hairs surround anterior eyes, some brown hairs on carapace, white hairs form two light streaks on thoracic part and small patch between anterior median eyes. Clypeal mat of hairs white. Chelicerae with two promarginal teeth and single wide tooth on retromargin. Mouth parts and sternum brown. Abdomen ovoid, dark brown with two transverse bands formed of white hairs, the first near anterior margin spreading to the sides and the second in the posterior half of the abdomen ( Fig. 189View FIGURES 189–194). Dense brown hairs along anterior edge of dorsum. Venter dark with four lines composed of light dots. Spinnerets light. Legs dark brown, only tarsi yellowish. Leg hairs and spines dark. Patella and tibia of pedipalp clothed in dense light yellowish hairs ( Fig. 189View FIGURES 189–194). Pedipalps light, only cymbium and bulb brownish. Structure of palpal organ similar to other members of the genus, diameter of embolic spiral large ( Fig. 190View FIGURES 189–194). Tibial apophysis thin and sharply pointed at tip, with serrate inner border near the tip ( Fig. 191View FIGURES 189–194).

Female. Generally similar to male, clypeus without white hairs, light streaks on thoracic part also absent. Abdomen blackish brown with mosaic composed of numerous small light patches with traces of lighter chevrons posteriorly. Venter light with a few irregular large dark stains. Epigyne with two narrow lateral semicircular depressions ( Fig. 193View FIGURES 189–194). Internal structure as in Fig. 194View FIGURES 189–194, seminal ducts in median part narrow, with accessory glands, spermathecae single chambered, elongated.
