Venturiella sinensis var. angusti-annulata Griffin
This is a species that has traditionally been reported as having a very limited range in North America. The most recent treatment of the species for North America is that of Pursell and Allen (2007) who indicate the species is present in Texas, Oklahoma, and Arkansas. The Texas record is from Culberson County, in the Guadalupe Mountains, of far west Texas and represents the first collection (and previously only) record for the state. Quedensley, Kruse, and Morse (2021) reported a collection from Montague County as part of a localized floristic survey. However, additional field work over the past 4 years has documented the species from 10 additional counties in the broader northeast Texas region. More field surveys are needed (and currently underway) to fully document the known range of this species.
