Odonbuthus: Pérez Minnocci, 1974: 28 . Diagnosis: The triangular sternum and absence of trichobothria on the ventral part of the pedipalp patella place Odontobuthus in the family Buthidae . The presence of prominent tooth-like processes (spiniform granules) on the ventrosubmedian carinae of metasomal segments II and III separate Odontobuthus from most other Iranian Buthidae, except Buthacus tadmorensis (Simon, 1892) and Kraepelinia palpator Vachon, 1974 . Species of Odontobuthus are easily distinguished from B.tadmorensis by the lyriform configuration of the carapacial carinae, and from Kraepelinia by their larger size (˃ 35 mm) and relatively longer fingers of the pedipalp chela. Kraepelinia is also easily distinguished from Odontobuthus by the extremely thickened base of the aculeus, the height of which is about half the height of the telson vesicle in lateral aspect, much greater than in Odontobuthus .

Odontobuthus may be separated from other genera of Buthidae by the following combination of characters (Stahnke, 1972; Farzanpay, 1987; Lourenço & Pézier, 2002; Lowe, 2010; Mirshamsi et al., 2013; Navidpour et al., 2013): cheliceral movable finger with two ventral denticles; carapace dorsal surface entirely horizontal in lateral aspect; carapacial carinae distinct, with lyriform configuration; pedipalp trichobothriotaxy type A-β; trichobothrium eb situated at distal end of chela manus or on fixed finger; patella trichobothrium d 3 situated prolateral to dorsomedian carina; proximal dentate margins of chela fixed and movable fingers not sexually dimorphic in adult male, i.e. without notch and lobe, respectively, in lateral aspect; median denticle row of chela fixed and movable fingers each comprising 10–14 oblique, non-imbricate subrows of denticles, each flanked by single prolateral and retrolateral accessory denticles; tibial spurs present on legs III and IV; pectines with fulcra; ventrosubmedian carinae of metasomal segments II and III comprising prominent tooth-like processes (spiniform granules); anteroventral carina of metasomal segment IV comprising prominent granules; ventrolateral carinae of metasomal segment V with prominent lobate processes; anal arch with prominent lobes laterally and reduced lobes posteroventrally; telson globose, without subaculear tubercle; hemispermatophore capsule with hook-like basal lobe and sperm hemiduct of three lobes.
