(1966)recorded it for eastern Nepal. Piippo (1990)indicated it for Jilin, Anhui and Taiwan in China. Bapna and Kachroo (2000)reported several occurrences in India. In Europe, this species was sometimes estimated as the current  Calypogeia azureataxon, which is not present in East Asia ( Buczkowska et al. 2018). The understanding of "  C. trichomanis" in East Asia is additionally complicated by synonymization of other names with '  C. trichomanis'; e.g., Hattori (1952)synonymized  C. angustaunder  C. trichomanisand created additional confusion.
