Old type catalogue. Weidner (1960), p. 63, No. 30. Syntypes (number not specified) (spelled as imperata).

Type status. Attems (1911a) did not specify the number of specimens in his description and Weidner (1960: 63) listed “ syntypes ” from Lion Mill and East Fremantle (as documented on file card). We agree that the present specimens are syntypes.

Additional type material. Type material (syntypes) from East Freemantle “Lion Mill” (no. 7008); Subiaco (no. 7009, 7011) and Boyanup (no. 7010), are held at the NHMW. Ilie et al. (2009: 36) noted, that “ ♂♂ and ♀♀ syntypes from Mundaring Weir, Collie, Boyanup and Pickering Brook are stored at the ZMB ( Moritz & Fischer 1979; no. 5148, 5148a–d), others from ‘Lion Mill’, East Freemantle are stored at the ZMH ( Weidner 1960: 63)”.

Collection remarks. The specimens were collected by Wilhelm Michaelsen during his expedition to Western Australia 1905.

Current systematic position. Ribautia imparata (Attems, 1911) ; transferred by Ribaut (1912: 86).
