A male specimen was designated as the holotype by Murayama (1995), and the specimen was retrieved in LBM ( Figs. 25–27 ; Dried Insect Database Reg. no. 1500022032).

Huang (2011) treated cuneomaculata as a junior subjective synonym of Thoressa masuriensis tali (Swinhoe, 1912) . We agree that cuneomaculata is a synonym of tali . The nominate subspecies masuriensis Moore, 1878 and subspecies tali are significantly different in appearance ( Figs. 46–49 ), but Evans (1949) considered them as conspecific. However, masuriensis ( Figs. 46–47, 50 ) and tali ( Figs. 48–49, 51 ) are two different species, supported by distinctions in genitalia ( Figs. 50–51 ) and the genetic divergence of COI barcode between them (12–13%, Table 1). They may be separated by the following features: 1) uncus bent with blunt tips in masuriensis ( Fig. 50 ) versus straight with narrowed tips in tali ( Fig. 51 ); 2) left harpe with inner one of terminal processes as small lobe in masuriensis ( Fig. 50 ) versus produced serrate teeth in tali ( Fig. 51 ); 3) phallus short and stout in masuriensis ( Fig. 50 ) versus elongate and slender in tali ( Fig. 51 ). Those masuriensis molecular samples in China ( Li et al. 2019) all belong to tali .

Huang (2011) was correct in merging the Chinese taxa of Thoressa Swinhoe, 1913 and Pedesta Hemming, 1934 . His taxonomic treatment, however, was not complete because he did not include the type species of Thoressa . The genus Thoressa sensu Evans (1949) was polyphyletic and is now divided into three genera based on molecular evidences ( Huang et al. 2019). Those species assigned to Thoressa by Huang (2011) indeed should be included in Pedesta . Therefore, Pedesta tali comb. nov. is the valid name for this taxon.
