Abstract

Two new species of caprellidean amphipods, Orthoprotella bicornis, new species, and Paraprotella teluksuang, new species, were discovered in shallow water coral reef and seagrass bed habitats in the Taman Laut Sultan Iskandar, Johor, South China Sea, off the east coast of Peninsular Malaysia. Orthoprotella bicornis, new species, is distinguished from other existing Orthoprotella species by the presence of several projections on the anterodistal margin of peduncle article 3 on antenna 1, head with 1 pair of dorsal projections, and propodus of pereopod 7 with a pair of grasping spine. Paraprotella teluksuang, new species, is close to P. saltatrix Takeuchi & Guerra-García, 2002, but differs in its lack of a suture between head and pereonite 1, single dorsal projection on head, 1 dorsodistal projection on pereonite 1 and paired mid-dorsal projections on pereonite 2. Keys to the species of Orthoprotella and Paraprotella are provided. Paraprotella teluksuang, new species, shows unusual sexual bias towards females, which is apparent in the absence of male specimens among the 360 individuals collected. This suggests that P. teluksuang, new species, is either a parthenogenetic species or is influenced by the presence of high environmental stress and/or parasitic infection.
