Hoplocampa pectoralis Thomson, 1871: 202–203 . Syntypes ♀, Gottland (sic!) , lectotype ♀ here designated (DEI- GISHym17569, images: https://doi.org/10.6084/m9.figshare.4763851), in MZLU. Type locality: Gotland ( Sweden) . Paralectotype ♀ (NHRS-HEVA000003421, images: https://doi.org/10.6084/m9.figshare.4764835), in NHRS.

Hoplocampa Oertzeni View in CoL [sic!] Konow, 1888: 188, 190. Syntypes ♂ ♀, Karpathos, lectotype ♀ here designated (GBIF- GISHym3804, images: https://doi.org/10.6084/m9.figshare.4772125), in SDEI. Type locality: Karpathos ( Greece). Paralectotype ♀ (GBIF-GISHym3805), in SDEI. Synonymy by Enslin (1914: 247).

Additional description. Body length: 3.0–5.0mm. Clypeus narrowly and deeply emarginate. Pale body colour yellowish. Fore wing costa and Sc+R similarly coloured, and darker than M+Cu. Female: Antennal flagellum entirely black (most northern and central European specimens), or more or less pale below (most southern European specimens); scape and pedicel more or less fuscous above, pale below. Upper head mainly black, usually with a pair of pale flecks anterior of ocelli, and outer orbits more or less pale. Whole occiput dark. Tegula and pronotum except extreme anterior yellow. Coxae usually completely yellow, rarely black-flecked. Abdominal terga and sterna from completely yellow except for black base of tergum 1, to extensively black on terga 1–4(–5). Sterna usually completely yellow, but rarely extensively fuscous. Even in darkest specimens, downturned edges of all terga remain pale. Valvulae 3 in dorsal view more than 2 × as long as basal width, gradually tapering; black. Lancet: Fig. 89 View FIGURES 89–93 . Male: Antennal flagellum largely pale, basal flagellomeres more or less fuscous above; scape and pedicel entirely pale. Head capsule entirely pale except for a contiguous patch around ocelli, postocellar area, and area of occiput directly behind this. Legs completely yellow. Medial area of only tergum 1 black, or a distally tapering black vitta reaching maximally to tergum 7. Penis valve: Fig. 105 View FIGURES 94–107 .

Total number of specimens examined: 37.

Similar species. See under crataegi , above.

Life history. Host plants: Crataegus spp. ( Pschorn-Walcher & Altenhofer 2000). Liston (2007) thought that pectoralis is attached to C. laevigata , rather than C. monogyna , but this was based only on observations on visits by adults to the respective inflorescences.

Distribution. Southern and Central Europe, including the British Isles; North to Denmark, and S. Sweden ( Taeger et al. 2006); Caucasus ( Zhelochovtsev & Zinovjev 1995), Transcaucasus, N. Iran, Siberia ( Lacourt 1999). A record from Sicily ( Liston et al. 2013) resulted from the misidentification of an unusually coloured female of crataegi (see key, and under treatment of H. crataegi ).

Occurrence in Sweden: published records: Skåne ( Benander 1966), Gotland ( Thomson 1871)
