New Flatworm Species Discovered: A Mysterious Invader in US

A new flatworm species, Amaga pseudobama, was discovered in North Carolina in 2020, initially misidentified as Obama nungara. Molecular and histological analysis revealed its resemblance to Obama nungara.

Discovery and Identification

New flatworm species found in North Carolina in 2020
Initially misidentified as Obama nungara, a South American species
Molecular and htological analysis revealed it as a new species
Named Amaga pseudobama due to its resemblance to Obama nungara
Brownish-black in color and just under an inch long
First discovered in a commercial nursery, later found in residential landscapes
International team of researchers involved in the identification process

Distribution and Spread

Confirmed presence in North Carolina and Florida
Samples from Florida dated back to 2015
Potentially present in Georgia and other southeastern states
Initial North Carolina samples found in plants shipped from Georgia
Exact distribution and establishment unclear due to limited observations
Resemblance to Obama nungara may hinder accurate identification through citizen science

Ecological Implications and Concerns

Terrestrial predatory flatworm, unusual for temperate regions like North Carolina
Preys on soft-bodied organisms such as earthworms and slugs
Potential threat to native ecosystems and soil fauna
Concerns about toxicity and possibility of carrying parasites
Unknown impact on local biodiversity and ecological balance
Joins other invasive flatworm species in the Southern United States

Research Challenges and Future Studies

Limited knowledge about Amaga pseudobama's behavior and ecology
No observations in its native habitat or wild environments
Unclear origin, possibly from South America like related species
Need for further research to understand:
- Precise prey preferences
- Reproductive rate and patterns
- Potential risks to native species and ecosystems
Importance of clearly identifying and naming new species for future studies
Molecular studies including complete mitogenome description conducted
