Mussel of the Month
The November 2021 Mussel of the Month is Namkongnaia lemeslei. Namkongnaia is a genus of two species described from southeast Asia.
MNHN. Battambang Province, Cambodia (type)
|
The genus Namkongnaia was described by Jeratthitikul et al. this year based on phylogenetic results. The genus basically represents the “species” that had been called Pilsbryoconcha lemeslei (Brandt, 1974) — except not the populations called “Pilsbryoconcha lemeslei” in recent molecular phylogenies, which apparently still go by that name.
We are proud that the MUSSELp database was useful to Jeratthitikul et al. (2021) to be able to discover a previously unacknowledged type series for N. lemeslei. |
