The salicis group

38. Stigmella assimilella (Zeller, 1848)

Nepticula assimilella Zeller, 1848: 327, 328.

Host-plants. Populus alba L., P. x canescens (Aiton) Sm., P. tremula L.

Distribution. Palaearctic. Widespread in Europe; also known from the Russian Far East (Primorskiy Kray) (possibly with a continuous distribution throughout Siberia) (van Nieukerken et al 2004).

39. Stigmella salicis (Stainton, 1854)

Nepticula salicis Stainton, 1854: 302.

Stigmella vittata Kemperman & Wilkinson, 1985: 28 –30 (see Discussion).

Host-plants. Salix spp., occasionally on Myrica gale L.

Discussion. According to van Nieukerken et al. (2012) S. salicis in fact is a complex of species. Possibly S. vittata is a good species after all (van Nieukerken, pers. comm.).
