Abstract
The first record of the non-indigenous, alien amphipod Grandidierella gilesi in the Lam Ta Khong River is presented. Previously, this Indo-Pacific amphipod had only been reported in the Indian Ocean, the Andaman Sea, the Gulf of Thailand, the South China Sea and Australia. In Thailand, G. gilesi was previously reported in an isolated pond in Bangkok. The present study constitutes another record of this species in inland water. The characteristics and variation of G. gilesi, observed in this study, are also discussed. All the specimens described here are preserved at the Princess Maha Chakri Sirindhorn Natural History Museum, Prince of Songkla University, Songkla, Thailand.
Highlights
Forty-three valid species of Grandidierella Coutière, 1904 have been recorded around the world (Horton et al 2019)
The Grandidierella gilesi, found in the present study, were similar to those described by Asari and Myers (1982) in gnathopod 2, each of which had a merus with long plumose marginal setae on the anterior margin, a carpus with two rows of long plumose setae and a propodus with long plumose marginal setae
The first record of the non-indigenous amphipod Grandidierella gilesi in the Lam Ta Khong River is presented. This Indo-Pacific amphipod was only found in estuaries and marine water areas
Summary
Forty-three valid species of Grandidierella Coutière, 1904 have been recorded around the world (Horton et al 2019). Grandidierella gilesi has been recorded in other estuarine places, such as in Songkhla Lagoon (recorded as Tale Sap), the Pattani River (Chilton 1925) and Lapinig in the Philippines (Schellenberg 1938) It has been reported in marine waters, such as in the Madras Coast, India (Asari and Myers 1982, Nayar 1959); the Natrang Coast, Vietnam (Imbach 1967); the Pinnakayal Coast, India (Sivaprakasam 1970); Surabaya, Java, Indonesia (Ledoyer 1979) and in the Port Beacon, Australia (Myers 1981).
