Mussel of the Month

The April 2023 Mussel of the Month is Scabiellus songkramensis. Scabiellus is a monotypic genus endemic to the Mekong Basin in Southeast Asia.

UF 507775. Pla Hang at Rt 222 bridge, Thailand.

This month’s mussel was originally described in the genus Scabies, but sufficient molecular phylogenetic sampling has consistently recovered Scabiellus songkramensis as a distinct branch (Pfeiffer et al., 2018; Bolotov et al., 2022). So, it has been reclassified in a distinct genus.

The phylogenetic relationships of Scabiellus songkramensis are summarized on the Scabiellus cladomics page.
