Metasoma ovoidal, slender, shiny, punctate, punctures very dense, moderately coarse to coarse; T 2 1.15 × as wide as long; S 2 with weak curved tooth-like process in middle on ventral surface; S 8 elongate with sides strongly convergent toward apex, distal margin emarginated medially, length/width: 1.32, with small and weakly raised tooth-like process in middle on ventral surface; genital capsule: paramere harpe straight apically; cuspis of volsella stout, shield-shaped, sharply pointed, strongly convex, ending below mid length of paramere harpe, without longitudinal carina; digitus of volsella equal in length of cuspis; midventral process of penis valve short and almost straight.

Intraspecific variation. Examined 80 ♀, 33 ♂. Female. Length: 3.3–6.2 mm; the colour is moderately variable, whereas the size is more variable; the head is blackish in most specimens, but frequently there are dark reddish tones and rarely a small to wide reddish spot on the vertex and occiput; the antenna varies from dark reddish orange to brownish to dark brownish with A 2 and A 3 lighter (most specimens), but it is almost uniformly light reddish orange in some specimens; the mesosoma is reddish orange, with the sides concolourous to moderately darkened; the legs are reddish orange to dark reddish, with the femora and tibiae darker, to extensively blackish, with the articular areas reddish orange; the metasoma is mostly blackish, with dark reddish tones in some specimens; the cuticular spots on T 2 are pale yellow (weakly evident) in most specimens, frequently with long and moderately dense recumbent setae overhanging the cuticular-spot boundaries; the spots are light lemon yellow (evident) in a few specimens; the spots are quite variable in size (distance between spots 0.5–2.5 × diameter of each spot), obsolescent in several specimens (more frequently in the North African specimens). Male. Length: 2.9–5.9 mm; the colour is moderately variable, whereas the size is more variable, similarly to the female; the head is blackish in most specimens, but some specimens have dark reddish tones and rarely a small reddish spot on the vertex and occiput; the antenna varies from dark reddish orange to brownish to dark brownish, with A 2 and the basal half of A 3 lighter (most specimens); the mesosoma is entirely reddish orange in most specimens, sometimes with the sides slightly darkened; the legs are reddish orange to dark reddish, with the femora and tibiae darker, to extensively blackish, with articular areas reddish orange; the metasoma is mostly blackish; the process on S 2 is very weak to absent in most specimens; the cuticular spots on T 2 are light yellow, moderately evident in most specimens, frequently with long and moderately dense recumbent setae overhanging the cuticular spot boundaries; the spots are light lemon yellow (evident) in a few specimens; the spots are very variable in size (distance between spots 0.5 –3.0 × diameter of each spot), obsolescent in many specimens (including the holotype and many North African specimens).

Distribution. Europe: Spain, Portugal, southern France (*), central and southern Italy, Sicily; North Africa: Tunisia, Algeria, Morocco ( Fig. 37 View FIGURE 37 ).

Remarks. The female was described subsequently ( Suárez 1958 b) and, although indicated and labelled as allotypus and paratypes, the females described by Suárez (1958 b) (examined) obviously do not belong to the type series, according to Article 72.4 of ICZN (1999).

The separation of this species from Bid. leopoldina is somewhat problematic, especially due to the wide range of variability of the size of the body of both species, which renders some features (e.g., processes on clypeus and shape of the head) less evident in some specimens; the size of the cuticular spots on T 2 is also very variable in both species and it is not a good diagnostic feature. The characters indicated in the key allow the identification of most specimens, with a confidence of about 90 %.

It is newly recorded from France.

Biology. Based on material examined, the species was observed from March to October (female) and June to October (male). The finding of a female specimen active in the late January, Southern Italy (Calabria) is remarkable.
