For more synonymy, see Lacourt (1999) and Taeger et al . (2010) . Additional description: female and male . Postocellar area with dull or inconspicuous anterior groove laterally. Clypeus with depth of emargination 0.3–0.4 × median length of clypeus. Malar space slightly wider than facet of eye in female, slightly narrower than facet in male; setae absent. Forewing with basal corner of cell 1M slightly acute (photos in Taeger et al. , 2018 ). In male, hind wing with apex of cell 1A not close to wing margin (fig. 2Q in Hara, 2011 ). Punctures mostly minute or inconspicuous. Mesoscutellum with only inconspicuous minute punctures. Mesoscutellar appendage mostly setose in female ( Fig. 5G ), posterolaterally setose in male. Dorsum of abdomen smooth, not microsculptured. Male genitalia with harpe widest near base, gently rounded on medial margin in ventral view (fig. 5D–F in Hara, 2011 ); penisvalve apically hooked.

Sommer ”.— AUSTRIA : 1♀ , “c. 1988 July , em. 1989-05-17 , Ritterkamp, NÖ”, “ Caliroa annulipes, Tilia cordata” and “ E. Altenhofer ” . Distribution . From Russian Far East to Europe, Canada ( Lelej, 2012 ). The record from China is based on a misidentification ( Wei et al ., 2006 , p. 510). The occurrence of this species in Japan was mentioned by Togashi (1960 , 1972 ) and Okutani (1965) . Togashi’s (1960) record of “ Caliroa ? annulipes ” from Honshu, Japan and Okutani’s (1965) “ C. annulipes ” are not C. annulipes but C. oishii (see also Hara, 2011 ). Togashi (1972) reported the host plant of C. annulipes in Japan . His material may be C. ouensis , because these two species are very similar as stated under the remarks of C. ouensis . A Japanese female of “ C. annulipes ” in Hara (2011) is not C. annulipes and here designated as the holotype of C. ouensis . We exclude C. annulipes from the fauna of Japan .
