Isoglossa Casey, 1893

Rheobioma Casey, 1906; Klimaszewski and Pelletier (2004), syn. of Neoisoglossa

Athetalia Casey, 1910 (in part); Klimaszewski and Pelletier (2004) syn. of Neoisoglossa

Neoisoglossa Klimaszewski & Pelletier, 2004; Gouix and Klimaszewski (2007), syn. of Isoglossa, unnecessary replacement name; Klimaszewski et al. (2020) as valid genus, incorrectly attributed to Casey (1893).

Comments.

In Klimaszewski et al. (2020), Neoisoglossa was incorrectly attributed to Casey but was actually proposed by Klimaszewski and Pelletier (2004), apparently as an unnecessary replacement name for Isoglossa Casey 1893. The previous treatment of these generic names and two other synonyms in the catalog of Gouix and Klimaszewski (2007) is correct and followed here. Blackwelder (1952) was wrong and there is no Isoglossa Newman that preoccupied Casey’s name, so Isoglossa Casey stands as valid with Neoisoglossa as a synonym.
