Study Extent
Magellanic RegionSampling
Pectinids specimens were collected between 2016 and 2019 by hand in SCUBA diving or apnea, in the shallow subtidal at five different localities in the Magellanic Region between 50ºS and 56°S: 1) Parker Island (Reina Adelaida Archipelago), 2) Montañas Fjord (Ultima Esperanza), 3) Ballena Fjord (western Magellan Strait), 4) Pia Fjord (Beagle Channel), and 5) Diego Ramirez Island. All specimens were preserved in ethanol 95° for subsequent genetic analyses.Method steps
- An exhaustive review of morphological literature on both species was carried out to gather the best identification criteria (Suppl. Mat. 1). The selected character described by Jonkers (2003) is the relation between the depth of the byssal notch (BN) and the height of the right valve (RV). To measure these characters, the right valve of all collected specimens was photographed, and the valve height (VH) and the depth of the byssal notch (BND) were measured.
