(Modified from Kovařík 1997). Total length about 40–65 mm in males and females (Figs 1–4). Male differs from female in having fingers of pedipalps proximally twisted (Fig. 5). Sixth cutting edge on movable and fixed fingers of pedipalps, usually with 3 external granules each (rarely 2 or 4 granules). First and second metasomal segments with 10 carinae, third and fourth segments with eight carinae. Ventral surface of seventh mesosomal segment with two carinae (not always discernible). Position and distribution of trichobothria on pedipalps as figures 5–9.

From its general morphology, Lychas mucronatus certainly related to Lychas krali Kovařík, 1995, described from Umphang River in Thailand. They have same important characters: second segment of metasoma with ten carinae, third metasomal segment with eight carinae; sixth cutting edge on movable fingers of pedipalps with two to four external granules; legs spotted. Lychas mucronatus can be distinguished from Lychas krali by the following characters: manus of pedipalps bright yellow with sparse, minute black spots, patella predominantly dark, compared with Lychas krali, in which the manus of pedipalps have the same color as patella and femur; pectinal teeth number 16–26, pectinal teeth 10–19 in Lychas krali; metasoma of approximately the same length in both sexes in Lychas mucronatus, whereas the metasoma much longer in males than in females in Lychas krali (Kovařík 1997: 360).

This species is common. We collected from mixed forest and buzzed canebrake. They are found in the bark, the gap of soil and under the stones.

(Taken from Kovařík 2000). Total length is 30–42.1 mm. Patella with 17 external trichobothria (5eb, 2 esb, 2 em, 4 est, 4 et) (Fig. 121) and 6–7 ventral trichobothria (6 specimens, Fig. 122). Pectinal teeth 4–5. Both males and females have fingers of pedipalps straight, without any flexure. The carapace bears very sparse large granules.

Scorpiops jendeki appears to be closely related to Scorpiops hardwickei (Gervais, 1843), both species have the same number of external and ventral trichobothria on the patella, and a similar length/width ratio of chela; however, in the latter the fingers of pedipalps are strongly flexed.
