Redescription of Marstonia comalensis, a Freshwater Snail from Texas
Author Information
Author(s): Robert Hershler, Hsiu-Ping Liu
Primary Institution: Smithsonian Institution
Hypothesis
The generic placement of Marstonia comalensis is confirmed by anatomical study.
Conclusion
Marstonia comalensis is a distinct species that has a critically imperiled conservation status and needs to be re-assessed for protection.
Supporting Evidence
- Marstonia comalensis has been live collected at only 12 localities.
- The species has a critically imperiled (G1) NatureServe ranking.
- Anatomical evidence supports the current generic allocation of Marstonia comalensis.
Takeaway
This study is about a rare freshwater snail that lives in Texas and might be in danger of disappearing.
Methodology
Anatomical study based on specimens relaxed with menthol and fixed in formalin, along with molecular phylogenetic analysis using mtCOI sequences.
Potential Biases
Potential misidentification of specimens in previous studies could affect the conclusions.
Limitations
The study relies on historical collections and may not reflect current populations.
