Diagnosis. Female. Brachypterous, fore wing rudiment emarginate apically ( Fig. 34 View FIGURES 33–41 ). Mesosoma and head concolorous, dark brown with reduced metallic lustre ( Figs 5 View FIGURES 1–6 , 33 View FIGURES 33–41 ); gaster dark brown. Legs brown to light brown with brown-yellow apices of all tibiae, tarsi except last tarsomere, and apices of meso and metafemora; scape from completely brown to variably extensively brown-yellow distally ( Fig. 35 View FIGURES 33–41 ). Head flattened, with lower parascrobal region abruptly angled to gena, forming a ridge between torulus and lower orbit ( Figs 35, 37 View FIGURES 33–41 ). Clypeus protuberant, convex, apically serrate ( Fig. 35 View FIGURES 33–41 insert). Scrobal depression deep, with sloping, non-carinate sides, reticulate to strigose ( Fig. 37 View FIGURES 33–41 ). Frontovertex between ocellar triangle and scrobal depression mostly mirror-like, with the least polished areas imperceptibly reticulate; obviously reticulate to strigose immediately above scrobal depression ( Fig. 37 View FIGURES 33–41 ). Mesoscutum imbricate-coriaceous to coriaceous-reticulate, with cells delimited by only slightly raised ridges ( Fig. 39 View FIGURES 33–41 ). Mesoscutellum and axillae sculptured as mesoscutum, fused into one contiguous structure, scutellum longitudinally depressed ( Figs 38, 39 View FIGURES 33–41 ). Acropleuron imbricate-coriaceous to coriaceous-reticulate, mesally almost smooth and polished ( Fig. 41 View FIGURES 33–41 ). Fore wing rudiment infuscated.

Male. Body dark brown to black with evident blue metallic lustre ( Fig. 6 View FIGURES 1–6 ) except smaller specimens almost without metallic lustre. Head in exact dorsal view 4.8–5.6× breadth of an eye measured along a transverse axis as in figure 73. Frontovertex between ocellar triangle and scrobal depression alutaceous to imbricate or slightly reticulate ( Fig. 72 View FIGURES 70–77 ). Scrobal depression completely and uniformly coriaceous to reticulate ( Fig. 72 View FIGURES 70–77 ). Funicle with first segment plus strongly reduced anellus 2.4–3.1× as long as wide ( Fig. 65 View FIGURES 53–69. 53–57 ). Mesoscutum coriaceous posteriorly, midlobe reticulate in anterior two thirds; lateral lobe coriaceous to imbricate-coriaceous. Mesoscutellum coriaceous. Metascutellum broadly Π-like, with lateroventral corners gently sloping, with dorsal margin flange-like carinated in larger specimens ( Fig. 67 View FIGURES 53–69. 53–57 ). Fore wing stigma subrotund to subquadrate and about as high as long, if elongated then rhomboidal (see remarks); uncus appears shorter than height of stigma ( Figs 53–57 View FIGURES 53–69. 53–57 ).

Distribution. Extensively distributed from Portugal to Armenia ( Korenko et al. 2013). Here newly recorded for Greece, Turkey and Morocco. Judging by the larger number of males of this species present in the examined material, it is a locally common species, but the easily recognisable females are rarely collected because they are brachypterous and presumably live at or near ground level.

Remarks. Masi (1919), when describing his new genus Calymmochilus, mentions two species: one that he described in the same paper, the type species of the genus ( C. atratus   ) and one that was mentioned but not named for unknown reasons. Masi indicates that this second species is brachypterous with the wings truncated after the postmarginal vein and that the gaster is laminately compressed in dead air-dry specimens ( Masi 1919: 327). Both characters were also included in the Latin description of the genus Calymmochilus and both are characteristic for C. dispar   females. Though we did not examine the specimen mentioned by Masi we conclude it was a C. dispar   . Latter it was again mentioned but not named by Bouček in Peck et al. (1964).

This is the only European species with brachypterous females, making them very easily recognisable. Males are also readily distinguished by the completely sculptured scrobal depression (smooth in all other species with known males). However, the smallest male of this species that was examined (1.1 mm) (CNC) has the dorsal half of the depression polished, only the ventral half being sculptured. This male from Morocco could represent a distinct species whose females are as yet unknown. However, it agrees with other males of C. dispar   in the proportions of the head, fore wing stigma and metascutellum shape, and it is part of a longer series of males of this species.

Because many mounted specimens have the scapes covering the scrobal depression, an additional useful character to use is the shape of the stigma on the fore wing. Even if it is variable in shape and can be from subrotund to subquadrate or rhomboidal it is about as high as long ( Figs 54, 55 & 56 View FIGURES 53–69. 53–57 right side, 57) and hence the uncus appears shorter than the height of the stigma. However, some males have the stigma elongated, but not transversely as in other species of the genus but rather as a continuation of the stigmal vein past the stigma ( Figs 53, 55 & 56 View FIGURES 53–69. 53–57 left side). Also, in all the examined males, only one wing (usually the left one) has the stigma elongated, the other one having it subquadrate ( Figs 55, 56 View FIGURES 53–69. 53–57 ). The allotype has the right fore wing stigma rhomboidally elongated ( Fig. 53 View FIGURES 53–69. 53–57 ) whereas the left fore wing is missing, being used to produce figure 11 in Bouček & Andriescu (1967) that shows a subrotund to subquadrate stigma. A similar bilateral asymmetry, but in the number of mesotarsal pegs, was documented in detail for Eupelmus vladimiri Fusu (Fusu 2017)   .
