Paratus Simon, 1898: 209 .

Paratus: Deeleman-Reinhold, 2001: 401 .

Type species: Paratus reticulatus Simon, 1898 from Sri Lanka.

Diagnosis (after Deeleman-Reinhold, 2001): Squat spiders with high, almost round carapace which strongly narrows in front. Leg length uniform, anterior tibiae and metatarsi with several pairs of strong ventral spines and some lateral spines. Abdomen almost globular. Paratus is distinguished from European liocranid genera by the absence of the retrocoxal window on coxae I.

The following characters may also help diagnose the genus: Chelicera with an enlarged seta bent at a right angle (Bh, Fig. 4 View FIGURES 1 – 7 ) originating near the base of fang. Male palp without distinct subtegulum, cymbium subequal in length to palpal femur, base of embolus continuous with tegulum, arising from the center of the tegulum, epigynal plate simple (without fovea, openings, grooves or outgrowths), epigyne with deep pocket, receptacula round. Abdomen with white guanine spots, carapace higher in thoracic part and very strong and long tibial and metatarsal spines.

Description. Medium sized spiders (2.60–4.60) with two claws, distinct pattern on carapace and abdomen, low clypeus, raised thoracic part of carapace, strong spines on legs I and II, white guanine spots on abdomen. Carapace width subequal to its length, light colored, with two pairs of dark bands (submedian and submarginal), lateral light band broken ( Figs. 1, 5–6 View FIGURES 1 – 7 ). Eyes subequal in size, clypeus low, about ½ of AME in height ( Fig. 4 View FIGURES 1 – 7 ). Thoracic part of carapace higher than cephalic area ( Fig. 2 View FIGURES 1 – 7 ). Chelicera with small teeth on both margins, with strong, characteristically bent near base of fang ( Fig. 4 View FIGURES 1 – 7 ). Maxillae relatively long ( Fig. 3 View FIGURES 1 – 7 ). Legs long, with distinct annulations ( Figs. 1, 5 View FIGURES 1 – 7 ), tibia I and II with 5 to 8 pairs of strong ventral spines ( Figs. 2–3 View FIGURES 1 – 7 ), metatarsi I and II with 3 pairs of long and strong spines. Abdomen with light cardiac spot and dark pattern on sides and venter, with irregular white guanine spots ( Figs. 1–2, 5–6 View FIGURES 1 – 7 ). Male palp with only one tibial (retrolateral) apophysis, long cymbium (about same length as femur), bulbus globular, without distinct subtegulum, without tegular (median) apophysis attached flexibly to tegulum. Conductor present in one species ( P. indicus sp. n.) and absent in another ( P. sinensis sp. n.). Embolus with long or very short stylus (St, extension of tip over embolic opening, Eo), seminal duct long, characteristically twisted near the base of embolus ( Figs. 11, 13–14 View FIGURES 8 – 14 ). Epigyne simple, represented by an undivided plate without any fovea or furrows. Receptacula round, insemination ducts short ( Figs. 23–26, 28–29 View FIGURES 22 – 29 ). P. sinensis sp.n. with pair of goffered diverticula. Diverticula became visible (expanded) after exposition of epigyne to lactic acid.

Composition. Three species, P. reticulatus Simon, 1898 View in CoL (Sri Lanka), P. sinensis View in CoL sp. n. (Yunnan, China), and P. indicus View in CoL sp. n. (Uttar Pradesh, India).

Distribution. Paratus is known from three localities in South Asia: Sri Lanka, foothills of Indian Himalaya, and South China ( Fig. 30 View FIGURE 30 ). Its occurrence in Vietnam, Nepal, Burma, Bangladesh is very likely.
