Yang (1938b: 223) indicated that this species actually has vestigial ocelli, thus precluding it from being a member of the genus Urolabida. The problem is that U. tenera is the type species for Urolabida. Yang indicated that U. tenera should be suppressed as type for Urolabida, that U. histrionica should be considered the type for this genus, and that U. tenera should be transferred to Urostylis. This has not been followed by anyone since his publication.
