The beach-hopper and land-hopper genus Floresorchestia Bousfield, 1984 is most widespread in terrestrial and marine littoral habitats and has been recorded from the South African coasts through to tropical Indo-Pacific and Caribbean Sea. In Thailand, there is only Floresorchestia samroiyodensis Azman, Wongkamhaeng & Dumrongrojwattana, 2014 reported from the swamp of Prachuab Kiri Khan, southern Thailand. In this work, two new species of Floresorchestia from Phutsa Reservoir in Nakhon Ratchasima and the man-made swamp in Burapha University are described. The new species are characterised by the mandible left lacinia mobilis 4-dentate; the posterior margin of merus, carpus and propodus covered in palmate setae; the uropod 3 peduncle with two robust setae and the telson longer than broad. The characters of the specimens are described and illustrated in this paper. All specimens are deposited in the Princess Maha Chakri Sirindhorn Natural History Museum, Prince of Songkla University, Thailand.

"กุ้งเต้นบูรพา (Floresorchestia buraphana Wongkamhaeng, Dumrongrojwattana and Pattaratumrong, 2016)" และถิ่นอาศัย (Burapha's land-hopper and its habitats)
ตัวอย่างของ new species ที่อยู่รอบ ๆ ตัวเรา ชื่อ F. buraphana นี้ตั้งเพื่อเป็นเกียรติแก่ มหาวิทยาลัยบูรพาในวาระรอบ 60 ปี และก้าวย่างสู่ปีที่ 61 และในฐานะที่เป็นสถานที่ที่พบกุ้งเต้นชนิดใหม่นี้ครั้งแรกของโลก รวมถึงเป็นที่ที่ทำให้มีวันนี้

Fantastic Burapha land-hopper (Floresorchestia buraphana) and where to find them. Our fellows may enjoy searching for the alive amphipod in their real habitat as the marks in the map together with breathing the warm winter.
