DIAGNOSIS (ADULT ♂ ♀). Total length of adults 24–32 mm. Petite ‘trichobothria’ d 2 on dorsal surfaces of pedipalp femur and patella reduced or absent. Chela smooth, carinae E and D1 weak or obsolete on manus. Pectinal tooth count 18–20 (♂), 16–18 (♀). Movable finger of pedipalp chela with 7 rows of median denticles, flanked by 7 ID and 7 OD. Metasoma III–V laterally and ventromedially punctate, without carinae except for smooth, rugose dorsosubmedian carinae, and ventrolateral carinae on metasoma V which are anteriorly obsolete and posteriorly weakly denticulate. Punctae small with diameters less than the mean distance between their centroids, together occupying much less area than smooth surfaces between them. Dorsal surfaces of all metasomal segments smooth without punctae or granules. Aculeus much shorter than vesicle, aculeus L/telson L ~0.20. Color of mesosoma dark green, metasoma and telson reddish brown; pedipalps and legs yellow to yellowish green, lighter on more distal segments. Tergites roughly granulated. Sternites IV–V with lateral surfaces coarsely granulated. Sternite VII with moderately dense, coarse granulation throughout, and four granulated carinae. Pedipalp, metasoma and telson glabrous, only metasoma V may have dorsolateral rows of setae, which can also occur on dorsal surface of telson. Moderately developed tibial spurs present on legs III and IV. Tarsomere I of legs I–III with 4–6 long setae in both sexes.

DISTRIBUTION. Yemen, south part of Socotra Island ( Fig. 119 ).
