Notes

Fig. 7

The COI sequence for DL 319 was 99.83 % identical to sequences of Oxyporhamphus micropterus (Valenciennes 1847) ( MZ 892547.1; MZ 050602.1, voucher FIFP 2021 - seq 16; MZ 028360.1), corroborating morphological identification of the egg. DL 315 was identified, based on morphological similarity to DL 319. This genus is widespread in the surface waters of the Atlantic, Pacific and Indo-Pacific Oceans, O micropterus occurring in Western Atlantic, Eastern Pacific and Indo-Pacific Oceans and Oxyporhamphus similis Bruun 1935 occurring in Western and Eastern Atlantic Oceans ( Collette 2004, Fricke et al. 2024). Adults have been recorded from Clipperton Atoll ( Fourriére et al. 2014). Based on COI sequences, eggs and larvae have been recorded from the Ninety East Ridge of the eastern Indian Ocean ( Zhang et al. 2021) and larvae have been recorded from Hawaiian waters ( Xing et al. 2022). Eggs are characterised by short, numerous, pointed spines on the chorion ( Ahlstrom and Moser 1980).
