Heterometrus wroughtoni is an Indian scorpion in the Scorpionidae family .
description
Heterometrus wroughtoni is a 95 to 130 millimeter long scorpion. Adult specimens have a reddish-brown basic color, including the legs. Juvenile scorpions are lighter in color and usually have yellow legs. The carapace has a smooth and shiny surface in the middle, with granules on the edges. The combs of the comb organ have 13 to 17 teeth in both sexes. The chelae are lobed, with a length to width ratio of 1.8 to 2 to 1. They are only sparsely hairy and covered with rounded granules that can form up to five rows on the outside. The chelae and the other members of the pedipalps show no sexual dimorphism . The telson is hairy and elongated, with a poisonous bladder that is shorter than the poison sting .
distribution and habitat
As Terra typica of Heterometrus wroughtoni , the sites Belgaum and Gadingal in Kolhapur were given in the first description . Belgaum is a city in the southwestern Indian state of Karnataka . It is located on the edge of the Western Ghats , near the border with the states of Maharashtra and Goa ( 15 ° 51 ′ N , 74 ° 31 ′ E ). Not far away is the city of Gadhinglaj (Anglicized Gadingal ) in the Kolhapur district , in the southwestern tip of the state of Maharashtra ( 16 ° 23 ′ N , 74 ° 35 ′ E ). At the time of the first description it was in the princely state of Kolhapur .
In addition to the locations of the type specimens, the states of Karnataka and Maharashtra, evidence from Andhra Pradesh and Tamil Nadu is available. A find was reported from Pakistan , but this was based on an incorrect determination of Heterometrus latimanus .
Systematics
Initial description
The first description was made by Reginald Innes Pocock in 1899 with only poor information on the morphology, which was limited to a brief description of the differences to Heterometrus fulvipes .
Type material
Pocock based his first description on an adult female scorpion from the Bengali region. This specimen was designated as a lectotype by Kovařík in 2004 . He determined three male and four juvenile scorpions from the same location as paralectotypes. These type specimens are in the collection of the Natural History Museum in London . The two male scorpions from Maharashtra (according to other sources from Tamil Nadu) as well as one male, two female and 18 juvenile paratypes from Bombay are in the collection of the Research Institute and Nature Museum Senckenberg, identified by Couzijn as the holotype and allotype of its species Heterometrus (Chersonesometrus) pelekomanus in Frankfurt am Main .
etymology
The species name honors the British-Indian forest officer and zoologist Robert Charles Wroughton .
Synonyms and misspellings (chronological)
- Palamnaeus wroughtoni Pocock , 1899 : the name was given by Pocock in his first description, but the genus Palamnaeus had already been declared a synonym for Heterometrus by Ferdinand Karsch in 1879 .
- Heterometrus (Chersonesometrus) wroughtoni Couzijn , 1981 : HWC Couzijn described the subgenus Chersonesometrus in 1981 , in which he also placed Heterometrus wroughtoni . Chersonesometrus and all other subgenera described by Couzijn were repealed in 2004 by František Kovařík in his revision of the genus Heterometrus .
- Heterometrus (Chersonesometrus) pelekomanus Couzijn , 1981 : This new species was described by HWC Couzijn in 1981. It was synonymous with Heterometrus wroughtoni in 2004 by Kovařík .
