Gasca, Rebeca & Hendrickx, Michel E., 2020, Species of Scina Prestandrea, 1833 (Amphipoda, Hyperiidea, Scinidae) from western Mexico with the description of a new species from the Gulf of California, Zootaxa 4803 (2), pp. 329-344 : 335-336

Scina submarginata Tattersall, 1906

Scina submarginata Tattersall, 1906: 12 ; Siegel-Causey, 1992: 98; Vinogradov et al., 1996: 184, fig. 72; Brusca & Hendrickx, 2005: 148 (list); García-Madrigal, 2007: 139 (list); Zeidler & de Broyer, 2009: 24 (list) (complete synonymy).

Material examined. TALUD XII, St. 15C (17°27’51”N, 102°10’43”W), March 31, 2008, 2F , MN from surface to 1530 m ( TD, 1880 m) (ICML-EMU-12465).

Eastern and worldwide Pacific distribution. From the Bering Sea to Isla Santa Catalina, southern Gulf of California ( Brusca & Hendrickx 2005; García Madrigal 2007). Off SW Mexico (present study; Fig. 4 ). This widely distributed species (type locality off Ireland, East Atlantic) occurs in the West Pacific, the Central Atlantic, and in the central part of the Indian Ocean ( Zeidler & de Broyer 2009).

Remarks. Scina submarginata is known to occur at depths between 200 and 4000 m. It is relatively easy to distinguish by features such as the distal extension of propodus in pereopod 1, but not in pereopod 2 (like in S. marginata ), and the basis of pereopod 5 with long anterodistal projection. The sizes of the two examined females were 4.5 and 5.8 mm.
