Heterarthrus microcephalus (Klug, 1818)

Tenthredo (Emphytus) microcephala Klug, 1818: 274-275. Holotype ♀, in ZMHUB (examined). Type locality: Berlin area ["in hiesiger Gegend"].

Phyllotoma salicis Kaltenbach, 1856: 257. Syntypes, cocoons. Type locality not stated (but presumably Germany, according to title of the work). This name is available according to the International Code of Zoological Nomenclature, Article 12 (Names published before 1931): Kaltenbach’s short description of the cocoon constitutes an indication (Article 12.2.8.). New synonym.

Type material examined.

Holotype Tenthredo (Emphytus) microcephala : ♀ "Microcephala Kl.", "M. Kl", “14139”, GBIF-GISHym2426" (ZMHUB).

Remarks.

Kaltenbach’s (1856) new name, Phyllotoma salicis , has apparently been overlooked until now, and was not mentioned in Taeger et al. (2010), or earlier catalogues. The name appears only once in Kaltenbach’s series of papers which catalogued the host associations of phytophagous insects in Germany, in the context of the description of Phyllotoma aceris Kaltenbach, 1856 (see under Heterarthrus leucomela ). Later, Kaltenbach apparently realised that his P. salicis had already been described, because he refers to the taxon as Phyllotoma microcephala Klug ( Kaltenbach 1869: 129).

Host plants and biology.

numerous Salix species (e.g. Buhr 1941). Oviposition in the tip of the leaf. Bivoltine; the second generation more abundant ( Altenhofer 2003).

Distribution.

Widely distributed in Europe ( Taeger et al. 2006), to north of the Arctic circle, the British Isles, and Iberian Peninsula; Transpalaearctic through Armenia, Kyrgystan, Kasachstan, West and East Siberia to the Russian Far East ( Sundukov 2017).
