Past DNA barcoding studies on Philippine anguillid eels came from Northern Luzon. This study aimed to determine the DNA barcodes of the freshwater eels of the Philippines using the cytochrome c oxidase 1 (CO1) gene of the mitochondrial DNA. Specimens were collected from six sites in the Philippines. Four Anguilla species – Anguilla bicolor pacifica Schmidt, 1928, A. celebesensis Kaup, 1856, A. interioris Whitney, 1938 and A. marmorata Quoy & Gaimard, 1824 and one Monopterus species– Monopterus javanensis Lacepéde, 1800 were collected and identified. Morphological features varied from the taxonomic guides for Anguilla celebesensis and A. interioris with their body color and fin length. Genetic divergence estimates using Kimura 2-parameter substitution model showed an intraspecific variation of 0–0.4% and interspecific variation of 4.1– 27.6%. The ML tree generated was similar to the previous studies and indicated the monophyly of the Indo–Pacific freshwater anguillid eel lineage. This study also reports the first genetic record of M. javanensis sampled from Batac, Ilocos Norte, Philippines.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43060820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four species of ocean sunfishes from Philippine waters are known to date: Mola mola (Linnaeus, 1758), Mola alexandrini (Ranzani, 1839), Masturus lanceolatus (Liénard, 1840), and Ranzania laevis (Pennant, 1776). However, in recent years, the taxonomy of Molidae (especially the genus Mola) has progressed at the global level, and it becomes necessary to review species that occur in Philippine waters. In this study, photographs of Molidae from Philippine waters were collected and morphological research involving museum specimens was conducted. The results of species re-identification based on the photographs of 12 specimens of Molidae obtained in this study were as follows: a specimen of M. alexandrini, five specimens of M. mola, and six specimens of Ma. lanceolatus. Although a specimen identified as M. alexandrini in a previous study was here re-identified as M. mola, the occurrence of M. alexandrini in Philippine waters was nevertheless confirmed in this study on the basis of another specimen. Mola alexandrini and Ma. lanceolatus were confused with M. mola locally, suggesting the importance of preserving real specimens, photographs and genetic samples.","PeriodicalId":37378,"journal":{"name":"Philippine Journal of Systematic Biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47379627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The blacknape large-eye bream, Gymnocranius satoi, has been reported to occur from Southern Japan, Taiwan to Northwestern Australia and to the Coral Sea, but has not previously been recorded from the Philippines. From 2011 – 2019, the National Fisheries Research and Development Institute (NFRDI) collaborated with the National Museum of Natural History of the Smithsonian Institution (NMNH/SI), USA, and the Old Dominion University (ODU), Virgina, USA, to inventory all commercial fish species sold in fish markets around the Philippines. During three (3) fish market surveys (Dumaguete City Market, Negros Oriental; Claveria Public Market, Cagayan, Northern Luzon; and Tabaco City Market, Albay, Southeastern Luzon in 2013, 2016 and 2017, respectively), we collected and eventually identified using morphological and DNA barcoding (COI) analysis, seven (7) specimens of G. satoi, representing the first records of this species from the country.
