Unveiling the identity of Diaurora Cockerell, 1903 (Bivalvia, Unionidae): morphology, molecular phylogenetics, and the description of a new species
The monotypic freshwater mussel genus Diaurora Cockerell, 1903 has long been enigmatic due to its rarity and morphological confusion with Acuticosta . In this study, we comprehensively redescribed Diaurora aurorea (Heude, 1883) through a detailed analysis of shell morphology and molecular phylogenet...

Summary: | The monotypic freshwater mussel genus
Diaurora
Cockerell, 1903 has long been enigmatic due to its rarity and morphological confusion with
Acuticosta
. In this study, we comprehensively redescribed
Diaurora aurorea
(Heude, 1883) through a detailed analysis of shell morphology and molecular phylogenetics of recently collected specimens. Moreover, a new species,
Diaurora laeve
sp. nov.
, was identified from the Fuyishui River, a tributary of the Zishui River in Shaoyang County, Shaoyang City, Hunan Province, China. Molecular phylogenetic analyses showed that
D. aurorea
and
D. laeve
sp. nov.
were reciprocally monophyletic and formed a clade as sister to
Schistodesmus
. Our study underscores the necessity of further exploring the diversity of freshwater mussels in understudied small tributaries throughout China. |
