Biogeography and diversity<\/strong><\/h3>\n

The genus Hofferia<\/em> is confined to the Palaearctic region. It contains two species.<\/p>\n

Phylogeny and classification<\/strong><\/h3>\n

Hofferia<\/em> is a member of the Heriades<\/em> group and sister to the genus Stenoheriades (Praz et al., 2008b).<\/span><\/em><\/p>\n

Nesting biology<\/strong><\/h3>\n

Hofferia schmiedeknechti<\/em> was observed to nest in beetle burrows in dead wood and to use resin partly mixed with small pebbles for nest construction (Tkalcu, 1984b; M\u00fcller & Trunz, 2014).<\/p>\n

Flower preferences<\/strong><\/h3>\n

Both Hofferia<\/em> species appear to be strict oligoleges on Asteraceae with a near exclusive or even exclusive preference for Carduoideae.<\/p>\n

Species accounts<\/strong><\/h3>\n

Hofferia schmiedeknechti <\/em>(Schletterer, 1889)<\/strong><\/h3>\n

1889 Chelostoma schmiedeknechti<\/strong><\/em> Schletterer, Zoologisches Jahrbuch f\u00fcr Systematik, 4: 638. Type material<\/span>: Holotype f, “S\u00fcd-Ungarn (Mehadia)” [Romania], HNHM (Budapest). Type species<\/span> of Hofferia<\/em> Tkalcu.-Combination Heriades schmiedeknechti<\/em> (Schletterer) in Friese (1911b: 22).<\/p>\n

1928 Heriades<\/em> tumida<\/em><\/strong> Benoist, Bulletin du Mus\u00e9um d’Histoire Naturelle Paris, 34: 332. Type material<\/span>: Holotype m, “Taurus” [Turkey], MNHN (Paris).-Synonymy in Zanden (1989: 80).<\/p>\n

Distribution-Europe: <\/strong>BG, GR, GR(Aegean Islands),<\/span> MK, RO<\/span>, SCG. Southwestern Asia: <\/strong>IL, IRQ, JOR, SYR, TR.<\/p>\n

Identification-Keys, Descriptions: <\/strong>Tkalcu (1984b: 15-19, 21); M\u00fcller & Trunz (2014: 178-179). Misapplication:<\/strong> Heriades schmiedeknechti <\/em>in Alfken (1936b: 7) is Chelostoma petersi<\/em> (Tkalcu).<\/p>\n

Nesting biology-Nesting site: <\/strong>Preexisting cavities: insect burrows in dead wood. Nesting material:<\/strong> The nests are closed with a thick plug of resin on the inside and a mixture of resin, soil and small pebbles on the outside; resin is also used for the construction of the thin walls that separate the linearly arranged brood cells. (Tkalcu, 1984b; M\u00fcller & Trunz, 2014; Rozen and Praz, 2016)<\/p>\n

Flower preferences: <\/strong>Oligolectic on Carduoideae; one pollen load also contained pollen of Asteroideae, suggesting that flowers of this subfamily are occasionally exploited as well (M\u00fcller & Trunz, 2014). Flower records: Carduus, Onopordum<\/em> (Tkalcu, 1984b); Centaurea, Silybum<\/em> (M\u00fcller & Trunz, 2014).<\/p>\n","protected":false},"excerpt":{"rendered":"
