( Figs. 29–31 )

Botria subalpina Villeneuve, 1910: 88 . Syntypes, male and female (IRSNB, examined). Type localities: France, Grenoble and Switerland, Neuchâtel.

Diagnosis. Similar to B. japonica , but differing as follows: male vertex 0.22–0.24 of head width; gena 0.30–0.35 of eye height; arista thickened on basal 3/5; male postabdomen with surstylus rather broad in lateral view, nearly straight in dorsal view; cerci slender in dorsal view; epiphallus somewhat elongate.

Body length. 5.8–6.4 mm.

Specimens examined. SWITZERLAND. 1 male, (BLKU) Jura, Develier, 12.iv.1964. GERMANY. 1 male, 2 females (BLKU), Hohe Mark Haltern, 26.iv.1960. No country data. 1 female (IRSNB), [labeled “Kullab, 3.4-26”].
