15. CHELIFEK PARADOXUS nov. sp. 



$ . Two large eyes, one on each side. 



Colour. Cephalothorax and tergites brown, palps reddish brown, 

 the under side and legs pale brownish. 



Cephalothorax much longer than wide (about as 4 : 3), nearly 

 parallel-sided till towards the eyes ; but the lateral contour is rather 

 irregular on account of the transverse grooves being a little produced 

 laterally; near the eyes the Cephalothorax is a little rounded, the 

 front margin nearly straight. Two transverse grooves very well 

 developed, the anterior one about in the middle, nearly straight, very 

 broad and deep, somewhat widened laterally ; the posterior groove 

 at about equal distance from the hind margin and the first groove, 

 nearly straight too, less developed ; the posterior corners of cephalo- 

 thorax not produced into a spine. The surface nearly glossless, 

 coarsely granulate, but with no bigger tubercles ; along the front 

 margin a row of distinctly clavate hairs ; the other hairs are 

 apparently broken. 



Abdomen long and slender. All tergites divided longitudinally by 

 a fine stripe. All tergites (except the last one) have a feeble, dark 

 lateral keel. The surface glossless and coarsely granulate, along the 

 hind margin each tergite is provided with short and strongly clavate 

 hairs ; no tactile hairs on the last segment. The sternites divided 

 longitudinally, glossy and shagreened, with fine and pointed hairs, 

 and additionally on the sclerites 6-9 provided with areas of bristle* 

 The species belongs to the subruber group. 



Palps somewhat longer than the body (with abdomen extended), 

 thus long and slender. Coxa glossy and slightly granulate or nearly 

 smooth ; the other joints glossy below, above nearly glossless, more 

 or less granulate, except the fingers. The hairs of the inner side 

 (especially those of trochanter and femur) distinctly clavate, the 

 other hairs dentate. Trochanter with a rather long stalk, a little 

 longer than wide, on both sides slightly convex, above with a strong 

 protuberance, which basally is nearly perpendicular, distally sloping 

 towards the extremity. Femur with a distinct stalk, about four 

 times as long as broad, thus rather slender, in front distinctly 

 concave, behind gradually widened from the stalk, the hind margin 

 distinctly convex, a little narrowing towards the tip, but femur on the 

 whole cannot be said to be club-shaped. Tibia with a rather long 

 stalk, about as long and as wide as femur, club-shaped, behind in the 

 greater central part slightly concave, convex towards the tip, in front 

 gradually widened from the stalk, the inner side distinctly convex. 

 Hand with a distinct stalk, and regularly rounded base, only a little
