Hoplocampa fulvicornis auct., nec Panzer

Additional description. Body length: 4.0–5.0mm. Clypeus broadly and shallowly emarginate. Thorax black, including pronotum and tegula. Pro- and mesofemur basally black or entirely pale. Apex of metatibia pale, to indistinctly fuscous. Metatarsus more or less fuscous. Female: antenna black, with flagellum indistinctly reddish ventro-apically. Lancet: Fig. 85 . Male: scape and pedicel black, flagellum nearly completely red. Harpes from completely black, to ventrally and dorsoapically partly pale. Penis valve: Fig. 103 .

Total number of specimens examined: 73.

Similar species. On external characters could be confused with fulvicornis , cantoti , or chrysorrhoea : see key. Whereas the lancets of cantoti ( Fig. 92 ) and chrysorrhoea ( Fig. 90 ) have a very different total shape compared to minuta ( Fig. 85 ), the lancet of minuta does not appear to be reliably distinguishable from that of fulvicornis ( Fig. 84 ). The penis valve of minuta ( Fig. 103 ) is most similar to that of fulvicornis ( Fig. 102 ), but in minuta the distal filament is shorter than the maximum height of the valviceps, whereas in fulvicornis it is much longer than the maximal height. Also, the valviceps is distally tapered in fulvicornis , but not tapered in minuta .

Life history. Host plants: Cultivated Prunus spp., particularly P. domestica ( Pschorn-Walcher & Altenhofer 2000) and P. salicina ( Roberti 1952) , less often P. avium ( Velbinger 1947) . In southern Europe P. armeniaca is affected ( Fintzescov 1921, Perju et al. 1995). Records of H. minuta on Pyrus in Japan refer to H. pyricola Rohwer, 1924 ( Velbinger 1944) . Biology: Sprengel (1930b), Miles et al. (1933), Ahlberg (1940), Roberti (1952), Bernard (1952).

Distribution. Southern, central and northern Europe, excluding the British Isles, and north to Denmark, Estonia ( Taeger et al. 2006) and Norway ( Jaastad et al. 2007); Caucasus, and Uzbekistan ( Zhelochovtsev & Zinovjev 1995).

Occurrence in Sweden: published records: Skåne ( Thomson 1871, Benander 1966), Blekinge, Halland, Småland, Östergötland ( Ahlberg 1940), Västergötland, Bohuslän, Närke, Södermanland, Uppland ( Lindblom 1936), Västmanland ( Ahlberg 1940), Värmland ( Lindblom 1936): Material examined: Skåne, Småland.
