Full Paper


The new cardinalfish Gymnapogon sagittarius sp. nov. is described on the basis of eight specimens from Vietnam, Malaysia and the Andaman Sea. The new species is most similar to the Red Sea species G. melanogaster Gon and Golani 2002 (known only from two specimens) in having 9 soft dorsal-fin rays, 8 soft anal-fin rays, and 13 total gill rakers, but differs in having 16 pectoral-fin rays (vs. 14 or 15 rays in G. melanogaster), body depth 12.0–15.1% of SL (mean 14.2%) (vs. 21.7–24.0%), eye diameter 5.2–6.1% (5.6%) (vs. 10.0–11.6%), interorbital width 3.7–4.4% (4.0%) (vs. 5.7–8.2%), and longest pelvic-fin soft ray length 12.0–15.6% (14.1%) (vs. 25.4–34.3%).

Nguyen (Institute of Marine Environment and Resources, Haiphong), A. Mazlan, Y. Seah and S. Tafzilmeriam (Universiti Malaysia Terengganu, Kuala Terengganu), and A. Arshad (Universiti Putra Malaysia, Serdang) for collecting specimens. We also thank Y. Haraguchi, and other volunteers and students of KAUM for curatorial assistance, and G. Hardy (Ngunguru, New Zealand) for reading the manuscript and providing help with English. HUMZ and KAUM specimens of G. sagittarius from Thailand were donated from PMBC and THNHM. This study was supported in part by the Sasakawa Scientific Research Grant from the Japan Science Society (29-747), Grants-in-Aid for Scientific, JSPS KAKENHI Grant Numbers JP19770067, JP26241027, JP24370041, JP23580259, and JP26450265; the “Biological Properties of Biodiversity Hotspots in Japan” project of the National Museum of Nature and Science, Tsukuba, Japan; “Establishment of Research and Education Network on Biodiversity and Its Conservation in the Satsunan Islands” project of Kagoshima University adopted by the Ministry of Education, Culture, Sports, Science and Technology, Japan; the “Island Research” project of Kagoshima University; and the MoU between Hokkaido University Museum and National Science Museum, Thailand. The Vietnamese specimen was collected with the support of the Institute of Marine Environment and Resources (Haiphong) and the Ha Long Bay Management Department (Ha Long), with permission for use of specimens granted by the Biodiversity Conservation Agency, Ministry of Natural Resources and Environment (Hanoi). Malaysian specimens were collected during the JSPS Asian Core Program, “Establishment of Research and Education Network on Coastal Marine Science in Southeast Asia”, and the JSPS Core-to-Core Program: B Asia-Africa Science Platforms, supported by the Ministry of Higher Education (Government of Malaysia), University Putra Malaysia, and University Malaysia Terengganu.
