endemic to a single nation
Regularity: Regularly occurring
Type of Residency: Year-round
Global Range: (200,000-2,500,000 square km (about 80,000-1,000,000 square miles)) It occurs from Illinois and Indiana south from North Carolina to Florida and west along the Gulf Coast to Texas and Oklahoma (Stark, 2004).
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: > 300
Comments: Stark (2004) cites Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Kansas, Louisiana, Missouri, Mississippi, Ohio, Oklahoma, Pennsylvania, Tennessee, and Texas. According to Lenat (2004), in North Carolina, this species (as Acroneuria mela) is from about 33 sites in coastal rivers, especially the Cape Fear, Neuse, Black, South and Waccamaw Rivers; however, Lenat (2004), also lists this species (as Acroneuria evoluta) from approximately 12 sites in the central slate belt, especially Randolph, Chatham, Stanley, Montgomery and Moore Counties. In Florida, it occurs in the Blackwater and Ochlockonee River drainages in the panhandle (Rasmussen et al., 2003). In Illinois, it is rare, occurring in the Middle Mississippi Border and Shawnee regions (DeWalt et al., 2005).

Names and Taxonomy
Comments: Acroneuria mela is a synonym of Acroneuria evoluta (Stark, 1998; Stark and Brown, 1991). The species Frison (1942) erroneously regarded as Acroneuria evoluta has been renamed Acroneuria frisoni (Stark and Brown, 1991).
