Type species – Meredithiella norrisii McNew, C. Mayers & T.C. Harr.
Notes – Meredithiella norrisii was collected from insect galleries and from male Corthylini punctatissimus beetles from Michigan and Iowa (Mayers et al. 2015). Meredithiella fracta and M. guianensis were subsequently introduced and their type cultures isolated from mycangium of Corthylus papulans and gallery of Corthylus crassus, respectively (Mayers et al. 2018). The genus is a symbiont with ambrosia beetle of the tribe Corthylini (Mayers et al. 2018). So far, members of the genus are only asexual morphs.
