DIAGNOSIS. Total length 45–62 mm. Mesosoma and carapace dark (grey to black) with orange spots and median black strip. Base color of metasoma, pedipalps ad legs yellow or yellowish red with dark spots, reticulations and dark carinae; telson yellow; chelicerae pale yellow, reticulated only in anterior part. Pedipalp movable fingers bear 11–12 rows of granules, obviously with 12 outer and inner denticles and fixed finger with 11 outer and inner denticles. Sexual dimorphism minor; chela of pedipalp narrow in both sexes, its length to width ratio 3.5–4.3 in females and 4.1– 4.8 in males. Telson bulbous, with aculeus shorter than vesicle. Pectinal teeth number 23–28 in females and 30–35 in males.
