Remarks.

Yen (1939) listed four ‘ paratypes’ in the SMF and figured one; referred to as ‘ cotypes’ by Zilch (1953). Sixteen type specimens are kept in the Gredler collection in the Franziskanermuseum Bozen (see Zilch (1974)). Kobelt and Möllendorff (1898) assigned this species to the subgenus Sinica .
