A new species of Calcinus is described from western Pacific material, including specimens previously identified as Cal-cinus anani Poupin & McLaughlin, 1998. The new species C. fuscus n. sp. differs from C. anani in the colouration in life,and their specific distinction is genetically supported by the barcoding gene cytochrome oxidase I (COI). The two speciesalso have different geographic distributions, with C. fuscus n. sp. ranging from Japan to the Philippines, Papua New Guin-ea, and New Caledonia, while C. anani is restricted to French Polynesia. Moreover C. fuscus n. sp. is found at shallower depths than its sister species C. anani.

A new species, Hornstedtia olivacea Docot & Pranada, from the province of Quezon, Philippines is described here with information on its distribution, habitat and phenology, along with a provisional IUCN conservation assessment. A second-step lectotypification of Hornstedtia conoidea Ridl. is proposed and a previous lectotypification of Hornstedtia microcheila Ridl. is clarified. Examination of the collection Ramos & Edaño 44454 supports the occurrence of Hornstedtia havilandii (K.Schum.) K.Schum. in the Philippines but new material is needed to check if the populations in the province of Sulu are distinct enough from the populations in Borneo to be recognised as a distinct taxon. An updated key to the Hornstedtia species of the Philippines is also provided.

Leptochelia Vatulelensis(Crustacea: Tanaidacea), A New Species From Anchialine Caves of the South-Western PacificLeptochelia vatulelensisn. sp., discovered on the small islands of Vatulele (Fijian group) and Ouvéa (Loyalty Islands, New Caledonia), is described and illustrated. The new species is distinguished from the others of the"Leptochelia-dubiagroup" (to which it is generally similar) by the following combination of morphological characteristics: (1) the presence of three to four distal setae on the maxilliped basis; (2) merus of pereopods III and IV with only a distosternal seta; (3) endopod of the uropods formed of four (rarely three) articles; (4) males with two (sometimes three) relatively short aesthetascs on the first five articles of the antennular flagellum; (5) male cheliped with a diminished dimorphism; (6) males with a vertical comb-row of setae on the cheliped propodus. Although it inhabits inland, anchialine caves, the new species lacks morphological features that are characteristic of some cave species.
