Pedipalps and legs have brown maculation, which is identical on femur and patella as well. The first metasomal segment has 10 carinae, whereas second through fourth segments have eight carinae. The fifth segment consists with five carinae in female but it reduced to three to five in male. Subaculear tooth is wide and rounded. There are 12 to 18 pectinal teeth in both sexes.

Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his ...

Buthidae
The Buthidae are the largest family of scorpions, containing about 100 genera and 1339 species as of 2022. A few very large genera ('' Ananteris'', '' Centruroides'', ''Compsobuthus'', or '' Tityus'') are known, but a high number of species-poor or monotypic ones also exist. New taxa are being described at a rate of several new species per year. They have a osmopolitandistribution throughout tropical and subtropical environments worldwide. Together with four other families, the Buthidae make up the superfamily Buthoidea. The family was established by Carl Ludwig Koch in 1837. Around 20 species of medically important (meaning potentially lethal to humans) scorpions are known, and all but one of these (''Hemiscorpius lepturus'') are members of the Buthidae. In dead specimens, the spine beneath the stinger, characteristic for this family, can be observed. List of genera and number of species The following genera are recognised in the family Buthidae: * '' Aegaeobuthus'' Kovar ...

Description They are medium sized buthid scorpions, where the adults range from 19 to 75 mm in length. Sternum type 1 is triangular in shape. Pedipalps are orthobothriotaxic. They have three to five pairs of lateral eyes. Tibial spurs are absent on all legs. Pedipalp movable finger consists with six rows of granules. Cheliceral fixed finger is with a single ventral denticle. Third and fourth legs consists with tibial spurs. Tibia and tarsomeres of legs I to III with setae are not arranged into bristle combs dorsally. Mesosoma has one median carina dorsally. Telson consists with subaculear tooth which is pointed or rounded. Males have longer metasomal segments and a wider pedipalp chela manus than females.
