( Figs. 24View FIGURES 23 – 30, 51View FIGURES 51 – 53, 63View FIGURES 57 – 66, 68View FIGURES 67 – 71)

Trisuloides rotundipennis Sugi, 1976  , Tinea  , 10 (5): 57, fig. 4–6, (TL: Japan, Fukuoka Pref.; Yoshii, Kyushu [HT: coll. Sugi, NIAES, Tsukuba).

Material examined. 1 male in worn condition with labels: Gifu ( Japan) [19] 15 Höne/ Trisuloides sericea  / T. rotundipennis  . Genital prep. 1878 (coll. ZFMK).

Diagnosis. Adult ( Fig. 24View FIGURES 23 – 30). The poor condition of the examined hampers detailed diagnosis, so we give the diagnosis of external characters by Sugi (1976): “Length of forewing 21.5– 23 mm in male, 23–24 mm in female. Forewing somewhat shorter, with apex slightly less produced, forming termen more roundish than in T. sericea  ; postmedial line oblique outward from costa to vein 5, whereas in T. sericea  it is indented just below costa and then excurved; on under surface subterminal space less powdered with grey than in T. sericea  . Otherwise almost identical with T. sericea  . In some specimens the postmedian line and the broad shade beyond it strongly suffused with whitish, the white extending interiorly around reniform, like forma pallidimacula Warren, 1912, of T. sericea  . ” In the male genitalia ( Figs. 51View FIGURES 51 – 53, 63View FIGURES 57 – 66) the uncus is somewhat wider, tegumen, vinculum and juxta similar to those of T. sericea  . Valva shorter and much broader at middle; harpe not digitate as in T. sericea  , situated rather transversely, bearing a large conical tooth-like process, pointed apically and a series of small spines at its posterior margin, one of them almost equal to main tooth in length; a heavily setose flap-like costal process (editum) is well developed. Aedeagus with posterior end more protruded ventrally than in T. sericea  , carina with few minute spines; vesica with basal and subapical diverticula. Female genitalia ( Fig. 68View FIGURES 67 – 71) figured by Sugi (1976) and described by Han et al. (2007). Papillae anales and apophyses as in T. sericea  , antrum much wider, cup-like; apophyses short, as long as papillae anales; ostium bursae strongly sclerotized along the antrum, with a broad plate on each lateral side; ductus bursae short; corpus bursae sacculate, very long, more than five times longer than ductus bursae; ductus seminalis falls into short appendix in caudal part of bursae.

Distribution and biology. Japan (Honshu, Shikoku, Kyushu), South Korea (Kangwon Prov.). The species was not included in the illustrated catalogue of Noctuidae  in Korea ( Kononenko et al. 1998), and was reported for Korea later by Han et al. (2007). It is probably bivoltine, with moths flying during June –July and September –October. In Japan, larvae feed on Quercus gilva ( Miyata et al. 2000)  .
