Redinger (loc. cit.) distinguishes two varieties based on colour differences, var. murina Redinger, being grey-brown to ashy-grey, and var. ochracea Redinger, ochraceous-yellowish to olive-brown. Types (W) for both varieties remain to be designated and additional collection and study should show whether subspecific rank might be warranted.
