Raja africana Capapé, 1977 is a primary junior synonym of Raja africana Bloch Schneider, 1801 and therefore permanently invalid (International Code of Zoological Nomenclature, article 57.2) and must be replaced. Raja africana Bloch Schneider, 1801 was first described by Bloch Schneider (1801: 367), based on a specimen from Guinea, West Africa (eastern Atlantic Ocean). The unique holotype is extant in the Zoologisches Museum of the Humboldt University, Berlin (ZMB 7837, a partial dry skin). The species was treated as valid as Urogymnus africanus (Bloch Schneider 1801) by Compagno Roberts (1984: 285), but later synonymized with Urogymnus asperrimus (Bloch Schneider 1801) in the subfamily Urogymninae of the family Dasyatidae (Myliobatiformes) by Compagno (1986: 141), Capapé Desoutter (1990: 63) and Séret (2016: 1418). It is widespread in the eastern Atlantic, Red Sea and IndoWest Pacific.

A checklist of the marine and estuarine fishes of New Ireland Province is presented, with special emphasis on Kavieng District, combining both previous and new records. After the recent KAVIENG 2014 expedition, a total of 1325 species in 153 families were recorded from the region. The largest families are the Gobiidae, Pomacentridae, Labridae, Serranidae, Apogonidae, Lutjanidae, Chaetodontidae, Blenniidae, Carangidae, Acanthuridae, Scaridae, Holocentridae, Syn-gnathidae, Lethrinidae and Scorpaenidae. A total of 810 fish species (61.1 % of the total marine and estuarine fish fauna) are recorded from New Ireland for the first time.The fish fauna of New Ireland includes 142 species in transitional waters and 1264 species in marine habitats, and 54 species species in freshwater habitats. Zoogeographically, 1179 species have a wide distribution range, most frequently a broad Indo-West Pacific distribution. Among the remaining species, just 12 are endemic to New Ireland.

Two new species of stargazers in the Uranoscopus albesca species-complex of the family Uranoscopidae are described from Papua New Guinea, which shares among other characters a concave posterodorsal margin of the pectoral fin. Uranoscopus brunneus n. sp. is described from a single specimen from off southwestern New Britain, and is characterised by lower edge of preopercle with 8 spines; labial fimbriae poorly-developed; anterior nostril with a long tubiform valve, posterior nostril a slit-like pore; supracleithrum with a sharp spine at rear end and five small spines inside; dorsoposterior margin of pectoral fin concave; 62 oblique scale-rows along the sides of the body in adult; pectoral-fin membranes dark brown. Uranoscopus kishimotoi n. sp., described from a single specimen from West Sepik Province, is characterised by the lower edge of preopercle with 3 spines; no labial fimbriae; both anterior and posterior nostrils with long tubiform valves; supracleithrum with a sharp spine at rear end and one additional small spine inside; dorso-posterior margin of pectoral fin concave; 59 oblique scale-rows along the sides of the body in adult; upper pectoral-fin membranes pale, lower membranes brown. The distribution of the species in the U. albesca species-complex is discussed.
