Goera tungusensis Martynov, 1909  , 246– 250, male, female. Goera  sp. 1: Ito et al. 2000, 23.

Adult. Body, wings, antennae mostly dark brown to black. Head short; ocelli absent; anterior setal warts round in female, very small in male; posterior setal warts large, round. Antennae 7–8 mm long; scape ca. 1 mm long, with long setae. In male maxillary palpi, distal segment long oval, membranous and elastic, with long setae on outer surface, brown scales on mesal surface and marginal frill. Forewing 8–10 mm lomg. Male abdominal sternite VI with 6–11 spines in comb-like arrangement, usually central ones longer and broader, but number, length and shape variable. Female abdominal sternite VI with several tiny spines.

Male genitalia. Segment IX long, oblique in lateral aspect; sternite IX slightly produced posteriorly, triangular in ventral aspect. Dorsal process of tergum X club-like in dorsal aspect, slightly swollen at basal 1 / 3 in dorsal and lateral aspect; lower semimembranous process present, deeply divided to pair of slender processes, unpigmented. Paired ventrolateral processes symmetrical, 2 times as long as dorsal process, strongly sclerotized, acute in apices, curved dorsomesad. Preanal appendage slender, longer than dorsal process of tergum X. Distal segment of inferior appendage with 2 processes; dorsolateral one large, triangular in lateral aspect, with slightly concave mesal face; mesal one strongly sclerotized, slender, acute in apex, curved dorsolaterad. Phallus long club-like in dorsal aspect with ventrolateral flange, simple in lateral aspect; phallic apodeme long, oval in dorsal aspect, acute anteriorly in lateral aspect.

Female genitalia. Tergum IX distinct, semicircular in dorsal aspect. Preanal appendages fused with tergum X ventrally, slightly concave dorsolaterally. Preanal appendage and tergum X rhombic. Lamella with dark pigmented plate. Gonopod plate rounded, protrudeed apicomesally; black sclerotized zone present at anterolateral corner. Spermathecal plate slender, slightly longer than gonopod plate

Larva. Lepneva (1966) described the larval stage of G. sajanensis Martynov 1924  , which probably is a junior synonym of G. tungusensis ( Levanidova 1982)  .

Specimens examined. Hokkaido: 1 male, Masuhoro-gawa, Wakkanai-shi, 25.viii.– 1.ix. 1998, K. Suzuki and T. Ito (TN); 1 female, ibid., 8–19.vi. 1998, K. Suzuki and T. Ito (TN); 2 males, Iwanano-sawa, Kamitoikan, Horonobe-cho, Hokkaido, 26.vi – 12.vii. 1993, M. Inoue (NK); 1 male, ibid., 25.viii – 14.ix. 1993, M. Inoue (NK); 2 males, near Shinsen-numa, Kyowa-cho, Hokkaido, 28.vii. 1994, Y. Sakamaki (NK); 1 female, Shumarinai, Horokanai-cho, 28.ix. 1996, reared from pupa by M. Aoyagi (TN).

Distribution. Japan (Hokkaido), Russia (Siberia, Far East), Canada (Quebec), USA (Alaska).

Japanese name. Kita-kuro-ningyo-tobikera.
