Methods & Sampling

The holotype was purchased at Yanbu fish market after being collected by hook and line in a nearby area and was deposited at the National Museum of Marine Biology & Aquarium (NMMB-P). Fifteen paratypes were obtained from Western Australia and deposited at the fish collection of California Academy of Sciences, San Francisco (CAS). These paratypes were part of a previous study using morphological and genetic data which revealed that two morphologically similar species were being identified as E. carbunculus, leading the authors to propose an undescribed species of Etelis (Andrews et al. 2016). That study generated DNA sequence data from cytochrome b (cytb) for the paratypes, and the sequences have been deposited in GenBank (Accession numbers MW151867- MW151881). [See Related Dataset "Etelis genetics" https://www.bco-dmo.org/dataset/873427 for genetic accession identifiers and methodology. The column "Field_ID" can be used to relate the Etelis genetics and Etelis morphology datasets.]

Methods for taking morphological measurements and meristics generally followed Hubbs & Lagler (1958), with some exceptions. The first anal spine was not measured because it was very short for this species. Upper and lower gillrakers were counted separately, as were rudiments. Length of caudal fin is measured from base of the fin to tip of upper lob. Length of caudal fin concavity is the length of upper lobe minus the length of middle of caudal fin base to middle of the concavity.

DNA sequences from cytb and cytochrome oxidase I (COI) were obtained from the E. boweni holotype and four E. radiosus specimens from the Yanbu fish market using previously described protocols (Andrews et al. 2016). The sequences were aligned with sequences used in phylogenetic analyses in Andrews et al. 2016, including cytb and COI sequences from six E. boweni and six E. carbunculus specimens collected across the Indo-Pacific, along with sequences from all other recognized Etelis species (six E. coruscans specimens, seven E. radiosus specimens, five E. oculatus specimens), and one specimen from each of two outgroups (Pristipomoides filamentosus and Aphareus rutilans). All sequences were then trimmed to a common length for each locus, for a total of 375 bp for cytb and 599 bp for COI.

Data Processing Description

BCO-DMO Data Manager Processing Notes:
* Exact locations for these samples are not available due to fish market acquisition. The region is known ("Indo-Pacific"). Bounding box coordinates were calculated in python using the multipolygon from marineregions.org ( MRID: 14289).
* Species column added to dataset with value "Etelis boweni" and verified by the data submitter.
* Taxa ID added to metadata Etelis boweni,1536489,urn:lsid:marinespecies.org:taxname:1536489
