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 man-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 of gnathopod 2 covered in palmate setae, palm reaching about 33% along posterior margin; uropod 3 peduncle with three robust setae; telson dorsal mid-line half the length of its breadth and four robust setae per lobe.

Two new species of the genus Floresorchestia (Crustacea, Amphipoda, Talitridae) from Amphawa Estuary, Samut Songkhram Province, Thailand

“…14, it is clear that coastal Floresorchestia species are more dominant than their terrestrial counterparts (and predominantly inhabit oceanic islands). Only F. kongsemae, F. boonyanusithii, F. malayensis and F. xueli were recorded in the mainland and some of them can establish their population in urban areas which are classified as field-and forest-hoppers (Wongkamhaeng et al 2016;Lowry and Springthorpe 2019;Suklom et al 2021;Tong et al 2021). Previous collecting efforts were substantially focused along the marine coastline while overlooking the inland areas that could certainly lead to low numbers of terrestrial species in the regions.…”

“…The genus Floresorchestia contains 24 valid species confined to the Indo-Pacific (Lowry and Springthorpe 2019) and East Afrotropical realms, comprising five ecological types (Lowry and Springthorpe 2019). Recent discoveries have also found three new terrestrial species, one being from China (F. xueli Tong & Hou in Tong, Hao, Liu, Li & Hou, 2021), one from Thailand (F. kongsemae Suklom, Danaisawadi & Wongkamhaeng, 2021) and another one from Kenya (F. mkomani Bichang'a & Hou in Bichang'a, Kioko, Liu, Li & Hou, 2021).…”
