Agallia pteridis Matsumura 1905: 68; Li 1987: 282, Fig. XXVI–231.

Japanagallia pteridis (Matsumura): Ishihara 1955: 215, Figs 1. 1–2, Figs 2. 1, 3, Figs 1–6.

Material examined. None.

Distribution. China (Guizhou, and Zhejiang Provinces, and Taiwan); Japan, Korea, Russia.

Remarks. The distinctive characteristics of J. pteridis (Matsumura) are: aedeagal shaft first directed caudally then abruptly upturned; and the pair of short processes at the base on the dorsal margin of the aedeagal shaft. It is similar to J. decliva Viraktamath et al. and J. tappana (Matsumura), and differs from the former in lacking apical lobes of the aedeagal shaft, and from the latter in lacking conical spines on the pygofer.
