“…Blackwater divers and photographers have introduced new opportunities to learn more about the diversity of larval marine fishes (e.g., Nonaka et al, 2021). Integrating diver encounters, photographs, and preserved specimens with examination and sequencing of these larvae is critical to increasing our understanding of the natural history of marine fishes (e.g., Pastana et al, 2022;Girard et al, 2023b). The capture of larval A. myersi and A. armatus by these divers inspired subsequent comparisons of larval ophidiids, leading to the identification of a nearly 50-year-old museum specimen of larval A. hextii.…”

“…Counts of fin rays and myomeres, among other traits, have allowed researchers to describe the larvae of thousands of species (e.g., Moser et al, 1984;Okiyama, 1988;Moser, 1996;Leis and Carson-Ewart, 2000;Richards, 2005;Fahay, 2007;Okiyama, 2014;Leis, 2015). Further, DNA barcoding efforts (e.g., Weigt et al, 2012;Baldwin and Johnson, 2014;Nonaka et al, 2021;Girard et al, 2023aGirard et al, , 2023b are substantially aiding these linking efforts and helping researchers identify new larval forms not yet known to science. Cusk-eels (Ophidiidae) are a family of approximately 280 species in 50 genera (Fricke et al, 2022) and represent some of the deepest-dwelling vertebrates on Earth (Gerringer et al, 2021).…”

The Ophidiidae is a group of more than 300 species of fishes characterized by elongated, snake‐like bodies and continuous dorsal, anal, and caudal fins. While describing a new species in the genus Monomitopus, we discovered a bilaterally paired fenestra on the dorsomedial surface of the neurocranium. We surveyed the distribution of this fenestra across species of Monomitopus and previously hypothesized allies in the genera Dannevigia, Dicrolene, Homostolus, Neobythites, and Selachophidium, finding variation in its presence and size. We also found a prominent bilaterally paired lateral fenestra and a posterior expansion of the exoccipital in the neurocrania of M. americanus and S. guentheri, with soft tissue connecting the back of the neurocranium to the first epineural and pectoral girdle in S. guentheri. In this study, we describe the distribution of and variation in these features. We integrate morphological characters and DNA data to generate a phylogeny of Monomitopus and allies to understand their relationships and trace the evolutionary history of these novel features. Our results call the monophyly of Monomitopus into question. The presence of the lateral neurocranial fenestra and posterior expansion of the exoccipital support the reclassification of M. americanus as a species of Selachophidium.

Accurate identification of fishes is essential for understanding their biology and to ensure food safety for consumers. DNA barcoding is an important tool because it can verify identifications of both whole and processed fishes that have had key morphological characters removed (e.g., filets, fish meal); however, DNA reference libraries are incomplete, and public repositories for sequence data contain incorrectly identified sequences. During a nine-year sampling program in the Philippines, a global biodiversity hotspot for marine fishes, we developed a verified reference library of cytochrome c oxidase subunit I (COI) sequences for 2,525 specimens representing 984 species. Specimens were primarily purchased from markets, with additional diversity collected using rotenone or fishing gear. Species identifications were verified based on taxonomic, phenotypic, and genotypic data, and sequences are associated with voucher specimens, live-color photographs, and genetic samples catalogued at Smithsonian Institution, National Museum of Natural History. The Biodiversity of Philippine Marine Fishes dataset is released herein to increase knowledge of species diversity and distributions and to facilitate accurate identification of market fishes.
