In October 2023, a single specimen of Oxymetopon compressus Chan, 1966 was retrieved from a discarded catch at the Mudasal Odai fish landing center on the southeast coast of India. This study marks the first record of the genus Oxymetopon in Indian waters, accompanied by a novel maximum length record. Oxymetopon compressus, closely resembles its congener, Oxymetopon formosum Fourmanoir, 1967 in having low supraorbital crest and head markings, but differs in having relatively a higher number of anal fin rays, 29 (vs. 27 in O. formosum). The anal fin count of O. compressus (29) is found higher than the Oxymetopon curticauda Prokofiev, 2016 (21–23) and Oxymetopon filamentosum Fourmanoir, 1967 (26), whereas it is found lower than the Oxymetopon cyanoctenosum Klausewitz et Condé, 1981 and Oxymetopon typus Bleeker, 1861 (31). This study describes the distinctive morphological and coloration patterns of the recorded species. |
