A new porcellanid crab from the Philippines, Polyonyx similis, is described from material collected through the PANGLAO 2004 Marine Biodiversity Project in the Philippines. The new species is morphologically allied to P. biunguiculatus (Dana, 1852) and has been confused with the latter species in previous studies. However, Polyonyx similis, new species, can be distinguished from P. biunguiculatus by the shape of the rostrum, the palm of the cheliped bearing flattened tubercles on the distal dorso-anterior surface, and the lack of male gonopods

Tytthoscincus temasekensis is a new species of swamp-dwelling skink from Singapore and the vicinity of Tanjung Malim, Perak, Peninsular Malaysia and the third species in the swamp clade of Tytthoscincus. It is distinguished from all other species of Tytthoscincus by the combination of having two loreals; two postsupralabials; 10–12 superciliaries; four supraoculars; interparietal contacting the 2nd–4th supraoculars; a shallow, pigmented tympanum; slightly enlarged, isolated, pectoral scales; 27–29 midbody scale rows; 55–65 paravertebral scales; 54–63 ventral scales; 9–11 subdigital lamellae on the fourth toe; keeled, subdigital lamellae; and a dorsal pattern of light-coloured stripes and/or linearly arranged spots. The growing diversity of the swamp clade in Singapore and Peninsular Malaysia begins to underscore the underappreciated contribution of swamplands to herpetological endemism and diversity as well as the need for its conservation.
