Adult ( Figs. 6 View FIGURE 6 , 8 View FIGURE 8 B). Brown, abdomen orange in fresh specimens, length 6.0–10.0 mm in male and about 8 mm in female. Warts on head and thorax, maxillary palpi, labial palpi and antennae as in A. (A.) kawamurai .

Forewings ( Figs. 6 View FIGURE 6 A, 8B) brown covered with fine brown hairs, each with fine hairs darker at posterior area in fresh specimens; 9.0–11.5 mm long in male and 9.5–12.5 mm long in female. Hindwings ( Figs. 6 View FIGURE 6 A, 8B) brown in preserved specimens, grayish black in fresh specimens, 6.0–8.0 mm long in male and 6.5–8.0 mm long in female; other characters as in A. (A.) kawamurai .

Male genitalia ( Fig. 6 View FIGURE 6 ). Tergite and sternite of segment IX ( Fig. 6 View FIGURE 6 B) fused laterally; lateral margins produced posteriorly into somewhat triangular lateral lobe on each side; lateral lobe acute or subquadrate in some specimens ( Fig. 6 View FIGURE 6 D). Median process of segment IX slender in dorsal and lateral views, with few very short setae. Roof-like plates of segment X compressed somewhat dorsolaterally with mesal notch and few short setae; posterolateral margins acute, heavily sclerotized and directed slightly ventrad ( Fig. 6 View FIGURE 6 E). Preanal appendages ( Figs. 6 View FIGURE 6 B, C) compressed laterally, long oval, with subacute apices in lateral view, rod-like in dorsal view, with many short and long setae laterally. Phallus ( Figs. 6 View FIGURE 6 B, F) thick and short, with U-shaped phallotremal sclerite. Inferior appendages ( Figs. 6 View FIGURE 6 B, G) branchless, slender, gradually tapered distally with subacute apices, covered with many short and long setae.

Female genitalia ( Fig. 6 View FIGURE 6 ). Segment VIII ( Figs. 6 View FIGURE 6 H, I) with subquadrate tergite and sternite, sternite with deep mesal cleft and many setae. Segment IX ( Figs. 6 View FIGURE 6 H, I) somewhat depressed; tergite and sternite touching each other ventrolaterally; sternite semicircular with distinct medial slit and many gently curved striations; tergite with small, roundish or subtriangular protuberance along each posterolateral margin, posteroventral margins truncate in ventral view ( Fig. 6 View FIGURE 6 I, arrow). Segment X ( Figs. 6 View FIGURE 6 H, I) fused with segment IX, covered with many setae. Vaginal sclerite ( Figs. 6 View FIGURE 6 K, J) sub-hexagonal with narrow proximal end in ventral view.

Pupa. Length up to 12 mm. Number of hooks of each anterior hook plate 2–4 (mostly 4), and that of each posterior hook plate 5–6. Other characters as in A. (A.) kawamurai .

Final instar larva ( Fig. 6 View FIGURE 6 ). Length up to 17 mm. Head ( Figs. 6 View FIGURE 6 L, M) slightly oblong, width 1.05–1.15 mm at cheeks; pale brown with small dark dots primarily along sutures and behind eye spots ( Figs. 6 View FIGURE 6 L, M). Hind legs ( Fig. 6 View FIGURE 6 N) light brown with dark bands on each femur, basal half of tibia, and sometimes on tarsus, but not on apical half of tibia. Other characters as in A. (A.) kawamurai .

Case. Similar to A. (A.) kawamurai .

Remarks. This species is very similar to A. (A.) kawamurai , but is clearly distinguished from the latter as in the remarks for A. (A.) kawamurai . Males illustrated by Ulmer (1907), under the name of A. immunis McLachlan 1863 , from an unknown Japanese locality, and by Oláh and Johanson (2010, figs. 17–21) under the name of A. (A.) kawamurai from Hokkaido, Japan, are undoubtedly A. (A.) pallidus based on the slender lateral aspect of the median process of segment IX. The unknown female and pupa of this species are described here.

Distribution ( Fig. 9 View FIGURE 9 ). Japan (Hokkaido, Honshu), Russian Far East (Khabarovsk, Primorye).

Japanese name. Usuiro-koban-tobikera (newly given here).
