We review members of the sisorid catfish genus Exostoma known from Thailand. Three species are recognized, of which two from the headwaters of the Chao Phraya River drainage in northwestern Thailand, are described here as new: E. effrenum and E. peregrinator. In addition to the two new species, E. berdmorei (which is here redescribed) is also known from the Salween River drainage in western Thailand. The three species can be distinguished from each other and other congeners by the morphologies of the adipose and caudal fins, as well as morphometric data for the eye diameter, head width, dorsal-to-adipose distance, body depth at anus, caudal-peduncle length, caudal-peduncle depth, and numbers of branched pectoral-fin rays and preanal vertebrae.

A new species of land hermit crab in the genus Coenobita Latreille, 1829 (Anomura: Coenobitidae), C. lila, is described from Singapore and adjacent countries. The new species has previously been confused with C. cavipes Stimpson, 1858, but they can be distinguished by the former possessing dense tubercles on the outer face of the palm of the left cheliped and the presence of a large sternal protuberance between the male fifth pereopods. Recognition of the new species is further supported by molecular data. In this study, the presence of C. cavipes in Taiwan is confirmed, and the status of C. baltzeri Neumann, 1878, is discussed. © National University of Singapore.

We record the presence of 35 cardinalfish species from the marine waters of Singapore based on a review of existing literature and examination of museum specimens. Another 13 species previously recorded as occurring in Singapore are considered doubtful records. Five of the 35 species reported here (Apogon crassiceps, Apogonichthyoides timorensis, Jaydia lineata, Nectamia similis, and Siphamia tubifer) are new records for Singapore, while another four species have not been encountered in more than a century © 2014 Check List and Authors.
