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. |
