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

Abstract

Two new species of Floresorchestia (Crustacea: Amphipoda) are described from Amphawa Estuary, Samut Songkhram Province, Thailand. Floresorchestia amphawaensissp. nov. is a riparian-hoppers living near agricultural and urban areas, being distinguished by the following character states: left mandible lacinia mobilis 4-dentate; gnathopod 2 palm reaching about 34%; telson as broad as long, with four robust setae per lobe. Floresorchestia pongratisp. nov. are described as riparian-hoppers living in the moist area near Mae Klong canal banks with a unique left mandible lacinia mobilis 5-dentate; gnathopod 2 palm reaching 30% and telson with seven robust setae per lobe. The status and the problem of diagnostic character states of the genus Floresorchestia are discussed.

Exophiala amphawaensis sp. nov., a novel black yeast isolated from the gut of amphipods in Thailand

“…In this study, fungi were isolated from gut of two amphipods ( Floresorchestia amphawaensis and an undescribed Dogielinotid amphipod) collected from Amphawa estuary, Samut Songkhram province, Thailand. Floresorchestia amphawaensis are riparian-hoppers living near agricultural and urban areas in dry areas including coconut plantations, man-made ditches and man-made ponds [18]. The undescribed Dogielinotid amphipod was discovered in Nipa palms ( Nypa fruticans ) in Amphawa district, Samut Songkhram province, Thailand, and it is not assignable to any previously known genus of the family Dogielinotidae.…”
