Rowlandius is a genus of the pygmy scourge scorpions (Schizomida), which consists of more than 50 known species and is mainly found on the islands of the Caribbean .
features
Like other dwarf scourge scorpions, the Rowlandius species are only a few millimeters in size.
Several species of the genus and other genera are known for the male pedipalps, which are variable and sometimes very pronounced within the species . These can be the same size as the females, but in many males they are three times the length. The males are divided into two groups according to the length of the pedipalps, which are referred to as homeomorphic (with the same length as the females) and heteromorphic (with larger pedipalps).
distribution
The known species of the genus live mainly on the Caribbean islands, individual species have been recorded on the South American continent. Most of the species are found in Cuba, Jamaica and Hispaniola. One species ( Rowlandius arduus ) lives in Venezuela on the South American continent ; a total of five species have been recorded in various regions of Brazil .
Systematics
The genus Rowlandius was established in 1995 by Reddell and Cokendolpher as part of a revision of the known dwarf scourge scorpions. It contains 54 known species, including the Rowlandius ubajara and Rowlandius potiguar from northeast Brazil , which were first described in 2013 .
