Subgenus
In biology, a subgenus is a taxonomic rank directly below genus.In zoology, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the Tiger Cowry of the Indo-Pacific, Cypraea tigris Linnaeus, which...

, Hottentotta (Hottentotta), Hottentotta (Balfourianus) Vachon, 1979, and Hottentotta (Deccanobuthus) Lourenço, 2000. The latest taxonomic review of this genus by F. Kovařík (2007) rejects this subdivision and recognizes a single, undivided genus Hottentotta. The differences separating the closely related genus Mesobuthus from Hottentotta are very subtle and species have been often been misassigned among the two genera.

General characteristics

Members of Hottentotta are generally moderately sized scorpions, with a total length of 70–90 mm (2.8–3.5 ); the smallest species are 30 millimetres (1.2 in) long, while the largest species reach 100–130 mm (3.9–5.1 ). They belong to the most colorful species of scorpions. The base color ranges from bright yellow to black, with most species colored in brown or reddish tones. Many species are ornamented by color spots or bands especially on the mesosoma
