Hoplocampa cantoti Chevin, 1986

Hoplocampa cantoti Chevin, 1986: 21–23 . Holotype ♀, not examined, in CBGP. Type locality: France, Eure-et-Loir, forêt de Dreux.

Additional description. Body length: 3.5mm. Clypeus broadly and shallowly emarginate. Female: Scape and pedicel black, underside of flagellum reddish. More or less gena, malar space and supraclypeal area pale (whitish). Metacoxa black with ventro-apical edge pale. Trochanters and femora entirely reddish. Valvula 3 black. The Swiss and Bulgarian specimens have pronotum, tegulae, and abdomen entirely black, whereas in the French specimens [according to original description] tegulae and posterior angles of pronotum are reddish, and underside of abdomen slightly reddish. Lancet: Figs 92–93. Male: unknown.

Total number of specimens examined: 10.

Similar species. Based on external characters, could be confused with minuta, chrysorrhoea, or fulvicornis: see key. The lancet (Fig. 92) has a highly distinctive shape, among W. Palaearctic species resembling only chrysorrhoea (Fig. 90). As illustrated by Chevin (1986), we found differences between these two species in the gross morphology of the lancets: narrower in chrysorrhoea, and apex curved somewhat upwards in chrysorrhoea, but straight in cantoti .

Life history. Host plants: not known for certain. The Bulgarian specimens were mostly swept from Prunus spinosa, and sometimes from P. domestica growing among these. Chevin (1986) suggested that the host is Prunus mahaleb, which is a characteristic component of the woody vegetation of the two known French localities. Howev- er, Prunus mahaleb was not seen close to the Bulgarian localities, and is not recorded at the Swiss locality (infoflora 2017). Therefore, we suppose that the host is Prunus spinosa .

Distribution. Bulgaria (Varna Province), France (Départements Eure-et-Loire, Indre-et-Loire), Switzerland (Canton Jura).

Occurrence in Sweden: not recorded, and not expected.
