Notes on the Splendid Perches of Genus Grammatonotus (Callanthiidae) of the Tropical Western Pacific (Philippines, New Caledonia, Vanuatu)


Based on the material obtained from the waters of the tropical Western Pacific (Philippines, New Caledonia, Vanuatu), three “large-eyed” species of Grammatonotus are redescribed: G. ambiortus, presumably widely distributed along island arcs in the western and central parts of the Pacific Ocean; G. cf. macrophthalmus from the waters of New Caledonia (new finding, but the specimens do not fully correspond to the original description, based on the fish caught at the Kyushu-Palau Ridge); and G. crosnieri, apparently endemic species in the Philippines waters. Clear diagnostic differences between these species were established, the structure of the caudal fin of G. ambiortus was described for the first time, and it turned out to be specific within the genus; the importance of individual morphological features in species diagnostics is discussed.

    According to the first description, the eye of the G. macrophthalmus specimen from the Kyushu-Palau Ridge is somewhat smaller (2.2–2.4 times in the head length), but its size also always exceeds the postorbital length (in all nine specimens); the ratio oo : po, calculated originally by the author of this study and based on data of the first description (Katayama et al., 1982. P. 372. Table 1), varies between 1.04–1.23. However, it cannot be excluded that this difference can be associated with growth, since specimens of the sample series are much larger than those investigated within the present study (SL 95–119 mm).

I am grateful to G. Duhamel (MNHN) for the opportunity to work with the collection of the Paris National Museum of Natural History and the managers of this collection for a variety of technical assistance. The study of the ichthyofauna of the tropical Western Pacific was performed within the framework of the state assignment no. 0149-2018-0033; the study of the morphology and systematics of the generalized percoid fishes was performed in the framework of the state assignment no. 0109-2018-0076. The article was written with partial financial support of the Russian Foundation for Basic Research, project no. 16-04-00365, and the lacking financial support was supplied by the author’s private means.
