Acetropis gimmerthalii (Flor, 1860)

Taxonomy. There are two subspecies: A. gimmerthalii gimmerthalii (Flor, 1860) and A. gimmerthalii parva (Wagner 1968) . In Poland occurs the nominative subspecies.

Morphology. Colouration is similar to the previous species, but often the male is paler, same coloured, or slightly more contrasted in colour than the female ( Fig. 1B, E ). The second segment of the antennae is bright, except for the apical part ( Fig. 10A ). Legs and antennae are covered with distinct black hair ( Fig. 10A ). Carina of pronotum is visible only in the middle part of pronotum ( Fig. 12B ). Female are mostly pseudobrachypterous.

Body length ( A. gimmerthalii gimmerthalii ). The literature ( Wagner 1952, 1970, Wagner & Weber 1964) gives the following sizes: male: 4.8–5.6 mm, female: 6.0–7.0 mm (macropterous form), 5.5–6.4 mm (pseudobrachypterous form). Measurements made on the basis of specimens from the authors' collection show that the males can reach up to 6.3 mm.

Biology. Like in the previous species, found in habitats of varying humidity.

Distribution (according to Kerzhner & Josifov 1999, Silfverberg 2012, Aukema et al. 2013, Lukashuk 2013; Fig. 4 ).
