Type locality. “Gallo-provincia” (located in Provence, South France).
Type material. According to Lelej (2002) the type material of Mutilla bipunctata Latreille, 1792 was lost, but recently, Pagliano (2005: 290) recorded the holotype in the collection of Massimiliano Spinola (Turin), a female bearing the following data: “ Myrmilla bipunctata Latr. ” (MRSN). The identity of this species has been checked and confirmed to us by G. Pagliano (2013, in litteris), but it was not possible to examine the type specimen directly as it was unavailable.

Intraspecific variation. Examined 79♀, 21♂. Female. Length: 4.1–8.9 mm; the colour varies slightly as well as the size of the setal spots on T2; the head is blackish, rarely with a small to wide reddish spot on the vertex, to entirely dark reddish brown; the mesosoma is mostly reddish orange, sometimes darkened, especially on the sides, in some specimens also the margins of the mesonotum are blackish (North-Africa); the legs vary from reddish to dark reddish to brownish, with the femora blackish. One small female from Tunisia (4.2 mm) has the body dark reddish orange overall, including the antennae and legs. Male. Length: 4.9–6.7 mm; the colour seems to vary on the basis of the body size e.g., smaller specimens are lighter overall, including the tegulae and legs reddish and the metasoma dark reddish; one specimen has a small irregular reddish spot on the vertex, just behind the ocellar area.
Distribution. Europe: Spain, Southern France, Corsica (?), North-Western Italy, Greece (?). North Africa: Morocco, Tunisia, Algeria, Egypt. Asia: Cyprus and Syria (?) (Fig. 36).
Remarks. According to Berland (1925), this species was doubtfully recorded in Central France by André (1901a: 199, 207), because its distribution in that country seems to be restricted to southern part. The records from Greece (e.g., Invrea 1964: 76; Lelej 2002: 29; Lelej & Yildirim 2009: 2; Koçak & Kemal 2009: 20) are vague and not based on material, and apparently referred to the old record by André (1901a: 199), which we cannot confirm based on material examined; moreover, contributions dealing with the mutillid fauna of the Balkans (e.g., Nonveiller 1976; Nonveiller et al. 1998) or specifically Greece (Giachino et al. 2000) have not reported the presence of Bla. bipunctatus. Therefore, we consider the presence of this species in Greece as doubtful and needing to be confirmed. Similarly, the old vague records for Corsica (Costa 1887: 94, 106) and Cyprus (André 1901a: 199, 206; André 1902: 25), in our opinion, require confirmation. Pagliano (2005: 287) recorded a specimen from Corse as Bla. bipunctatus under the name “ Mutilla cyrnea ”, but we cannot ascribe this name to any described taxon; judging from Pagliano’s (2005: Fig. 3) photograph of the relevant box, this is an unpublished Spinola name for what Spinola considered a variety of M. halensis; we have not been able to examine the specimen, but the (small) photograph looks more like a specimen of Bid. chiesi than Bla. bipunctatus. The presence in Syria is based on only one female, without exact locality, present in Coll. Ernest André (MNHN) (examined). Finally, the record for Egypt, although old and vague, is considered reliable, since it is corroborated by a detailed description which fits Bla. bipunctatus well (André 1910: 43).
Biology. Based on material examined, this species shows a wide phenological range, with females collected mainly between March and October, and some collected earlier (January–February) in N-Africa; the males were collected in June–September. It is recorded as a parasitoid of Halictidae (Férton 1898; Brothers et al. 2000).
