Strandesia

One hundred and seventy-seven species of subfamily Cypricercinae have thus far been described worldwide ( Savatenalinton & Martens 2010, Martens & Savatenalinton 2011, Chang et al. 2012, Nagler et al. 2014). The zoogeographical region with the highest specific diversity for this subfamily is the Oriental region, with 29% of the total number of cypricercinid species, followed by the Neotropical and the Afrotropical regions with 25% and 22% of the species, respectively. In the Oriental region, most of the species found were recorded from Southeast Asia, including Thailand. The non-marine ostracods from Thailand have been continuously studied during the last seven years and several new species and records have been published. Nine out of 15 species recently reported from Thailand belong to the Cypricercinae and four of these belong to the genus Strandesia ( Vávra 1906, Savatenalinton & Martens 2009a, b, 2010, 2013, present study). There are presently 103 Strandesia species worldwide and 30 of these species occur in the Oriental region ( Tab. 2). In addition, about 95% of the Strandesia species in this region are endemic to it. The present contribution brings the number of Strandesia species found in Thailand to seven.

Based on the frequency of occurrence, the genus Strandesia in the Oriental region can be divided into three groups: rare species (species found in one country and few localities) (21 species), uncommon species (species found in few countries but in several localities) (2 species), common species (species found in several countries and in many localities) (7 species) ( Tab. 2).
