Revised description. Male . Wings brown, light brown patterns on forewings often indistinct in alcohol; light brown dots absent in hind wings. Forewings each 2.0 mm long, hind wings each 1.7 mm long (n = 1). Antennae brown, each 1.2 mm long, 30-segmented (n = 1). Short ventromesal process on abdominal segment VII. Genitalia ( Figs 4 A–4D). Segment IX with strongly produced anterolateral margins, reaching up to middle of abdominal segment VII, small rounded mid-dorsal process (d.pr.) on posterior margin. Dorsal plate (d.pl.) mostly membranous, elongate with large, subcircular concavity apicomesally in dorsal view. Subgenital plate (s.pl.) broadly triangular in ventral view. Inferior appendages (i.a.) elongate-triangular, apices curved laterodorsad. Aedeagus slender and slightly curved ventrad apically with titillator at basal 2/5, subapical process absent. Female . Unknown. Specimens examined . Japan , Honshu, Kyoto : 1 male , Uji-shi, Makishima-cho, Uji-gawa, Ingen-bashi, 24.vi.2012 , S. Kobayashi. Shiga : 1 male , Otsu-shi, Oishi-higashi, Seta-gawa, Shishitobi-bashi, 16.vii.2014 , S. Kobayashi. Distribution . China ( Anhui , Fujian , Sichuan ), Japan (Honshu). Remarks . The male of this species is somewhat similar to that of the widely distributed Japanese species, H. oguranis , in having a broadly triangular subgenital plate and almost straight phallic apparatus, but differs from the latter as follows: The dorsal plate has a large round excavation apically in H . parapiculata , but a shallow excavation apically in H . oguranis ; the phallic apparatus is slender and simple apically in H . parapiculata , but bifurcate apically in H . oguranis . Japanese name . Nise-ogura-hime-tobikera.
