DIAGNOSIS. Total length
28–32 mm
. Sexual dimorphism minor, adult males with chela of pedipalps broader and fingers of pedipalps flexed proximally; there is no difference in length and width of metasomal segments. Base color uniformly yellow to yellowish brown, with dark spots. Movable finger of pedipalp bears 10 rows of granules, all without external and with internal accessory granules (
acutecarinatus
group of Levy & Amitai, 1980). Pedipalp chela length/width ratio 4.0 in males and
4.8 in
females. Manus of chela shorter than fixed finger. Trochanter of pedipalps with one to twelve spinules and without setae. Anterior margin of carapace bears 8 symmetrically distributed spinules. First to third metasomal segments bear 10 carinae, fourth bears 8 or 10 carinae. All metasomal segments longer than wide. Pectinal teeth number
18–21 in
males and
15–18 in
females. Sternites and ventral surface of metasoma granulated. Seventh sternite bears four crenulate carinae. Telson bulbous, aculeus shorter than vesicle. Subaculear tubercle present, long and spinoid.
