Type material examined. Lectotype female [ BMNH] of Orthoneura bimaculata Blood & Kryger, 1928 , here designated to avoid the existing ambiguity about the type specimens of this nominal species. Also, in order to avoid any uncertainty about the identity of this species, the same female is also designated here as the neotype of Orthoneura bimaculata Blood, 1923 , type specimens of which are lost (and probably these unknown syntypes of both sexes had not been marked or even properly preserved). The lectotype is on a slide ( Fig. 17 ) labeled: 1. "B. N. BLOOD PREPARER TRICHOGRAMMINAE Orthoneura bimaculata ♀ TYPE 5.1530a [in red, added later]"; 2. [in India ink on glass] " Tumidiclava "; 3. " THIS SPECIMEN HAS NO TYPE STATUS " (both a correct and an incorrect statement by an unknown researcher or curator because it is a syntype of Orthoneura bimaculata Blood & Kryger, 1928 but could not be a syntype of Orthoneura bimaculata Blood, 1923 as it was collected in 1924); [in pencil] "Published in 1923"; 5. "Kings Weston, Bristol 1.VII.1924 ".

The lectotype ( Fig. 18 ) is complete, uncleared, perfectly spread out. The type locality is Kings Weston Down (near Bristol), Bristol, England, UK ( Blood & Kryger 1928). Paralectotype: 1 male ( Fig. 19 ) [ BMNH] on slide ( Fig. 20 ), labeled similarly to the lectotype except for "♂", "5.1530b" in red (added later), and the collecting date " 27.VI.1924 ".

Diagnosis. FEMALE (based on specimens from Austria and Italy). Two dark spots on mesoscutum relatively long ( Fig. 21 ), bearing distal pair of setae; fore wing with marginal vein straight.

MALE (based on specimens from Italy). Antenna ( Fig. 22 ) rather short, with 2 small anelli, the second anellus appressed to club; club 5-segmented, with 5 PLS, claval segments almost of equal length.

Distribution. Austria (new record), Czech Republic ( Kalina 1989), France ( Nowicki 1940), Hungary ( Nowicki 1940), Italy (new record), Ukraine (Fursov 2007), and United Kingdom ( England) ( Blood 1923; Blood & Kryger 1928; Fursov 2007).

Hosts. Unknown.

Comments. Orthoneura bimaculata Blood, 1923 was described from an unspecified number of specimens of both sexes from around Bristol, England, UK ( Blood 1923). In the far more detailed description, Blood & Kryger (1928) specified the number of type specimens of Orthoneura bimaculata Blood & Kryger, 1928 (two syntypes, a male and female on slides, in BMNH). Additional non-type specimens were deposited by them in the Zoological Museum, Natural History Museum of Denmark, University of Copenhagen, Copenhagen, Denmark (ZMUC). According to Lars B. Vilhelmsen (personal communication), only one microscopic slide (number 17.4, labeled " Orthoneura Soc. Ent. Med. Engl. Kings West. Down") was found in ZMUC that undoubtedly belongs to the material mentioned by Blood & Kryger (1928). It is an incomplete specimen of unknown sex of which only the head, wings, and a few leg segments remain.
