Polypedilum tsukubaense (Sasa)

( Fig. 37 )

Polypedilum (Polypedilum) tsukubaense ( Sasa, 1979: 17, Figs. 27–28 ) (as Microtendipes ). [Holotype A8: 01.] Sasa (1983: 12–13, Fig. 7 H–N).

Polypedilum (Polypedilum) chubetuabeum Sasa et Suzuki, 2001a: 2 , Fig. 1 a–h. [Holotype 404: 050.] Syn. nov.

Sasa (1983) transferred Microtendipes tsukubaense Sasa to the genus Polypedilum Kieffer. The superior volsella of P. (P.) tsukubaense bears two long setae on medial margin and a long subapical seta on the lateral margin. P. (P.) chubetuabeum shares these characters with P. tsukubaense ( Fig. 37 ) and is considered to be a junior synonym.
