Polypedilum (Polypedilum) tsukubaense (Sasa)

Microtendipes tsukubaensis Sasa, 1979: 17 .

Polypedilum tsukubaense: Sasa 1983: 12; Sasa & Suzuki 1991: 94 (as Polypedilum s. str.). Microtendipes iriocedeus Sasa & Suzuki, 2000: 12 . Syn. nov.

Remarks. The holotype male of M. iriocedeus Sasa & Suzuki may be lost (A. Shinohara, pers. comm.). In the original description of M. iriocedeus, the authors (2000: 13) wrote, “Wing bare, without dark marks, R2+ 3 in contact with R1. Tip of fore tibia with a long, narrow and apically pointed terminal process”, and “Oral or anterior margin of 8th abdominal segment is inverted V-shaped like in Polypedilum species”. These are features of Polypedilum rather than Microtendipes . Further, they draw the foretibial scale in the somewhat lateral view (p. 31, fig. 12e), and noted that the superior volsella is somewhat sickle-shaped, apically hooked, and has 1 or 2 inner setae arising at about basal one-third, and one lateral seta, and the gonostylus is slender, widest at about middle. It shows that the species belongs Polypedilum s. str. and conspecific with P. (P.) tsukubaense (Sasa) .

The adults, male and female, are very similar to those of Polypedilum (Polypedilum) flavescens (Johannsen, 1932) collected from Indonesia in the morphology or even conspecific, especially the structure of male hypopygium. Polypedilum (P.) tsukubaense almost satisfies the original description of P. flavescens, except that the foretibial scale is rounded apically. In P. (P.) flavescens, the scale is pointed apically, according to Johannsen (1932: 521).
