Descriptive terminology follows Mattoni & Acosta (2005) for the hemispermatophores, Vachon (1974) for the trichobothria, and Francke (1977) for the metasomal carinae, abbreviated as follows: DL: dorsolateral; LIM: lateral inframedian; LSM: lateral supramedian; VSM: ventral submedian; VL: ventrolateral; VM: ventromedian.
Legs: smooth tegument, with two well developed and symmetrical pedal spurs; telotarsi low and elongated, with a ventromedian row of hyaline setae of the same length as the VL spines, and with well developed ventrolateral spines; spinal formula typical of the group: tarsus I: 1-1 (n = 15); tarsus II: 2-2 (n = 15), tarsus III: 4-4 in most specimens (n = 13), but in some cases there is one additional external spine 4-5 (n = 2), tarsus IV: 4-5 in most specimens (n = 12), but in some specimens there is an additional internal spine 5-5 (n = 3); telotarsal ungues symmetrical, very curved.

The granulation, ventromedian, and ventrolateral carinae of metasomal segment V are less developed compared with those of the preceding segments such that the segment has a shinier, rounded appearance in R.
Segment V, dorsosubmedian carinae absent; dorsolateral and ventrolateral carinae continuous, costate-granular, granules subequal; ventrosubmedian carinae obsolete, granular, reduced to anterior half of segment; ventromedian carina continuous, costate-granular, granules subequal, without posterior bifurcation.
Additionally, both Odontobuthus and Apistobuthus have strongly modified ventromedian carinae on metasoma II-III, and Odontobuthus, Leiurus and Apistobuthus have lateral carinae on tergites I-II that are either V-shaped, or split into a pair of carinae (in the case of Leiurus).
martensii, the ventromedian carinae of the metasomal segment II and III are crenulate and the granules are evenly developed; the ventrolateral carinae of the metasomal segment V are serratocrenulate and the granules are evenly developed or slightly increasing in size posteriorly; the pedipalp chela is slender with Cl/Cw = 4.
4): dorsolateral carinae strong, granular, serrate on distal third; lateromedian carinae strong, serrate on basal half, then weakening to disappear in distal third; ventrolateral and ventromedian carinae strong, serrate.
