Isometrus Basilicus
''Reddyanus basilicus'' is a species of scorpion in the family Buthidae. Description There is high variability in morphometric characters between small males with 27 to 32 mm long after the fourth ecdysis, and larger males 40 to 46 mm long after the fifth ecdysis. Total length is 27 to 46 mm. Male has longer metasomal segments and telson than female. Segments of pedipalps are the same length and width. Pedipalp movable finger is clearly longer than chela manus. Base color reddish. Pedipalps and legs dusted with brown maculation, which is identical on femur and patella as well. First metasomal segment has 10 carinae, whereas second through fourth segments have eight carinae. The fifth segment has five carinae in female but three to five in male. Subaculear tooth is wide and rounded. There are 13 to 18 pectinal teeth. References basilicus Animals described in 1879 {{Scorpion-stub ...

Ferdinand Karsch
Ferdinand Anton Franz Karsch or Karsch-Haack (2 September 1853, in Münster – 20 December 1936, in Berlin) was a German arachnologist, entomologist and anthropologist. The son of a doctor, Karsch was educated at the Friedrich Wilhelm University in Berlin and published a thesis on the gall wasp in 1877. From 1878 to 1921 he held the post of curator at the Museum für Naturkunde Berlin. Between 1873 and 1893, he published a catalogue of the spiders of Westphalia; he also published numerous articles on the specimens that the museum received from various explorers and naturalists working in Africa, in China, in Japan, in Australia, etc. This publication of others' work sometimes led to disputes over priority and nomenclature, for example with Pickard-Cambridge. Alongside his zoological activities, he published many works on sexuality and, in particular, homosexuality in both the animal kingdom and in so-called "primitive" peoples, including ''Das gleichgeschlechtliche Leben ...

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 s ...

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'' Kovarik, ...

Reddyanus
''Reddyanus'' is a genus of buthid scorpions native to Oriental region from India, Sri Lanka, China: Tibet, to Melanesia. The genus was previously described as a subgenus of '' Isometrus''. 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.
