Type material: Holotype ♂ (MHNG), IRAQ: Khanagin-Dyala, 180 km N of Baghdad, ii.1964, G. Pringle.

Diagnosis: Odontobuthus bidentatus may be separated from other species of the genus by the following combination of characters. Scorpions of medium to large size, adults 51–76 mm (♂) and 56–83 mm (♀) ( Fig. 15 ). Colour yellow. Median ocular tubercle situated in anterior half of carapace, distance from anterior carapace margin, 0.32–0.37. Pedipalp chela movable finger long relative to manus (MFL/ML, 1.93–2.51). Median denticle rows of pedipalp chela fixed and movable fingers each comprising 13 or 14 oblique subrows of denticles. Pectinal tooth count, 33–35 (♂) and 24–29 (♀). Ventrosubmedian carinae of metasomal segments II and III each with two to three pairs of prominent tooth-like processes ( Fig. 22A ). Metasomal segment IV length to width (L/W), 1.67–2.09. Ventrolateral carinae of metasomal segment V with three or four prominent lobate processes; anal arch with three prominent lobes laterally; posteroventral margin of metasomal segment V with four reduced lobes. Telson small, narrow, length to width (TL/W), 1.94–2.27 and length to height (TL/H), 2.00–2.43 ( Figs 20A , 21A ).
