Apion punctigerum Thunberg, 1815: 118 Fig. 4

Original description.

A. punctigerum: niger, elytris nigris, striatis.

Habitat in Smolandia Sveciae.

Magnitudine pediculi totus opacus, niger.

Elytra gibba, striata, atra.

Material studied.

I have received three specimens, as follows: one divided into three parts and glued onto a square white card, this on a short thin pin with head, with data: 543a, Mus. Thunb.; one headless, worn, pinned high on a long thin pin with head, with data: 543b, Mus. Thunb.; and a third glued to a rectangular label, this on a short thick pin with head, with data: 1191, Smol. The first specimen is a female of Aspidapion radiolus (Marsham, 1802), the second a female of either Ceratapion gibbirostre (Gyllenhal, 1813) or Curculio carduorum (Kirby, 1808), and the third is an etiolated (probably female) specimen of Ischnopterapion (Ischnopterapion) loti (Kirby, 1808). The first two are coloured brightly, with the elytra more or less metallic, and do not fit Thunberg’s description. The third fits Thunberg’s description, although the body colour has become brownish, and is labelled with the type locality, Smolandia (= Småland, Sweden). I hereby designate this specimen as the lectotype of Apion punctigerum Thunberg, 1815, and its name becomes a new synonym of that of Ischnopterapion loti .
