DIAGNOSIS. Total length 24–40 mm. Sexual dimorphism minor, adult males with chela of pedipalps flexed proximally only little, smaller males almost straight; there is no difference in length and width of metasomal segments. Base color uniformly reddish to gray. Pedipalps with or without spots. Movable finger of pedipalp bears 10 rows of granules, all without external and with internal accessory granules ( acutecarinatus group). Manus of chela shorter than fixed finger. Trochanter of pedipalps with numerous long setae. Anterior margin of carapace bears eight symmetrically distributed spinae. First to third metasomal segments bear 10 carinae, fourth bears 8 or 10 carinae. All metasomal segments longer than wide. Pectinal teeth number 19–27. Seventh sternite bears four crenulate carinae. Telson bulbous, aculeus shorter than vesicle. Subaculear tubercle present but not spinoid.

COMMENTS. Taxonomic position of the species is unclear. Preliminary results of DNA analysis (paper in preparation) indicate that it could be a synonym of Compsobuthus abyssinicus (Birula, 1903) .
