Mussel of the Month

The January 2021 Mussel of the Month is Solenaia emarginata. Solenaia is a genus of three species found in East Asia.

USNM 86787. Siam [Thailand] (type).

We already tried, back in February 2008, to choose a species of Solenaia for the Mussel of the Month. But, Balwantia soleniformis got revised to a different genus (a different tribe!). In fact, the old Solenaia (Graf & Cummings, 2007; Zieritz et al., 2018) has been broken into at least for genera: Solenaia, Parvasolenaia, Koreosolenaia, and Balwantia (Huang et al., 2019; Lopes-Lima et al., 2020).

This time we will make sure we pick a shell that will stick in Solenaia: the type specimen of the type species, Solenaia emarginata.

Since we last dealt with Solenaia sensu lato, S. khwaenoiensis has been lumped with S. emarginata, S. carinata has been resurrected from synonymy with from S. iridinea, and two additional species have been described. The prevailing name in the literature for S. iridinea (Heude, 1874) is S. oleivora (Heude, 1877), but they have been treated as synonyms (Haas, 1969; He & Zhuang, 2013), and S. iridinea has priority.
