Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.
Pethia macrogramma is a small freshwater fish only known from near Myitkyina, Kachin State, in northern Myanmar. While it has potential for use as an ornamental species, there are no reports of its use. It has never been reported as introduced or established outside of its limited native range. History of invasiveness is uncertain. P. macrogramma has a low climate match with the contiguous United States. No georeferenced occurrences were available for the climate matching analysis, so source locations had to be estimated based on a verbal description of the established range. Because little is known about this species, further information is needed to adequately assess the risk it poses to the contiguous United States. Certainty of this assessment is low, and the overall risk assessment category is uncertain.
