Lin & K.C. Chou; 2 ♀ (NTM; both identified as “ Parapolybia indica ” by Sk. Yamane in 1994), 159 K, Central Cross Highway, Hualien, [9.ix.1989, C.C. Chiou; 12.viii.1989, J.T.

MALE. Body length 12.0–13.0 mm; fore wing length 10.0– 11.5 mm. Male antenna length 9.0 mm; F11 about 0.8 mm long, 1.8 × as long as F10.

Distribution. Taiwan.

Remarks. Starr (1992), having examined the holotype of P. takasagona, concluded that P. takasagona was a valid species and the senior synonym of Parapolybia nodosa van der Vecht, 1966; this synonymy, however, has not been accepted (see Yamane et al. 1995; Kojima et al. 2011). Yamane et al. (1995) examined the holotype of P. takasagona and concluded that P. takasagona was a junior synonym of P. indica (de Saussure 1854). Their synonymy, however, as pointed out by Kojima et al. (2011), was not based on a robust taxonomic considaration. Not only based on differences in coloration (Fig. 78) but also morphological differences [less developed female gena (Fig. 33), club-shaped T1 (Figs. 34–35)], we have concluded that P. takasagona is a good species and might be endemic to Taiwan.
