Floresorchestia kongsemae sp. n. a new species (Crustacea: Amphipoda: Talitridae) from Kasetsart University, Bangkok, Thailand

Abstract

The genus Floresorchestia (Bousfield, 1984) is widely distributed in terrestrial and marine coastal habitats. It has been found from coastal South Africa through to the Indo-Pacific region and the Caribbean Sea in Central America. Two species of Floresorchestia have been reported in Thailand, Floresorchestia boonyanusithii Wongkamhaeng et al. (2016) and Floresorchestia buraphana Wongkamhaeng et al. (2016). This work reports on a new species of Floresorchestia found at Kasetsart University in a human-made pond and neighbouring areas.Classification of the new species was achieved by considering the left mandible 5-dentate; gnathopod 2 posterior margin merus carpus and propodus covered in palmate setae, palm reaching about 33% along posterior margin; uropod 3 peduncle with three robust setae; telson dorsal midline half the length of its breadth and four robust setae per lobe. The breeding season, distribution, and tentative migration are also discussed.
