This is one of five species of the flatfish genus Pseudorhombus recorded from Singapore which include Pseudorhombus arsius, P. malayanus, P. neglectus (Fowler, 1938: 80-81), and P. javanicus recently recorded from the western Johor Strait at Tuas (Lee et al., 2017). In Singapore, Pseudorhombus elevatus was first recorded from the eastern Johor Strait by Ng et al. (2015: 320). It is distinguished from its congeners in the area in being comparatively deeper bodied (body depth 1.7 to 2 times in standard length); having no enlarged teeth in both jaws; pale brownish body with a distinct large dark blotch at the junction of the straight and curved parts of the lateral line, and many dark rings and spots scattered on the body; and a distinct notch in front of the eyes along the head profile in front of the upper eye (Amaoka & Hensley, 2001: 3851).

A collection of the caridean shrimp genus Glyphocrangon A. Milne-Edwards, 1881 (Glyphocrangonidae), made during the South Java Deep-Sea Biodiversity Expedition 2018 (SJADES 2018), is comprised of six species, including one new to science: G. hakuhoae Takeda & Hanamura, 1994, G. indonesiensis Komai, 2004b, G. juxtaculeata Chace, 1984, G. proxima Komai, 2004b, G. serratirostris, new species, and G. sibogae de Man, 1918. Glyphocrangon juxtaculeata, which was originally described on the basis of a single juvenile holotype and previously placed in the synonymy of G. regalis Spence Bate, 1888, is herein reinstated as a valid species on the basis of examination of a newly collected female specimen. Glyphocrangon serratirostris, new species, belongs to the “G. regalis” species complex, but is quite distinctive in having four or more lateral spines on each side of the rostrum. Genetic analyses using partial segments of the mitochondrial COI gene also supports the recognition of the new species.

The atlas moth seems to be common in Singapore, especially from November to January. The larvae is a general feeder and many types of cultivated trees are among its food plants. The gregarious larvae defoliating an entire tree in the featured observation apparently occurs only occasionally. It is likely that they have hatched from eggs laid on a single tree by an injured or immobilised female moth (Morrell, 1973: 81). The caterpillars found on the ground and moving away from the tree they had defoliated were presumably on their way to infest nearby trees.

A new species of a potamid crab belonging to the genus Demanietta Bott, 1966, is described from Adang Island, Andaman Sea, off Satun, south Thailand. Demanietta sunthorni, new species, belongs to a group of Demanietta species which has a distinct epibranchial tooth, and strong epigastric and postorbital cristae on the carapace. It can be distinguished from all congeners most easily by the form of the male first gonopod which is slender, with the terminal segment sinuous, upcurved and possessing a large dorsal fold. This is the southernmost record of the genus.
