Key to the Greek Amicromias species

1. Pronotum and head with rostrum lacking appressed scales, densely covered with erect slender apically curved setae....... 2

- Pronotum and head with rostrum with rounded to slender appressed scales, with sparse semierect to erect slender to subspatulate setae............................................................................................3

2. Rostrum at basal third distinctly tapered anteriad, then about parallel-sided, dorsally with concave sides. Protibiae more robust, 5× as long as wide at midlength, apically widened inside and straight outside, at apex distinctly equally wide as at midlength. Antennal scape more robust, at apex 0.9× as wide as club. Elytral intervals 4× as wide as striae...... A. platanegrachei sp. n.

- Rostrum dorsally almost evenly tapered apicad. Protibiae slender, 7× as long as wide at midlength, apically widened outside and inside, at apex distinctly wider than at midlength. Antennal scape more slender, at apex 0.7–0.8× as wide as club. Elytral intervals twice as wide as striae......................................... A. tricholepis Yunakov & Germann, 2008

3. Larger species, 3.3 mm. Appressed elytral scales entirely concealing integument of dorsal part of body...... A. cunevi sp. n.

- Smaller species, at most 2.5 mm. Appressed elytral scales sparse, not concealing integument.......................... 4

4. Appressed elytral scales widely V-shaped, base of scale distinctly shorter than twice length, each scale with laterally expanded fringes. Pronotum wide, 1.56–1.68× as wide as long. Elytra short oval, 1.23–1.28× as long as wide. Antennal scape gradually enlarged from base to apex. Erect setae at apical declivity shorter than half the width of one interval, sparse, distance between two setae longer than length of one seta. Spermatheca with ramus and nodulus equally long............. A. yunakovi sp. n.

- Appressed elytral scales oval with short apical indentation, base of scales distinctly longer than twice its length, parallel-sided tips. Pronotum narrow, 1.32–1.39× as wide as long. Elytra long oval, 1.35–1.38× as long as wide. Antennal scape enlarged at apical third. Erect setae at apical declivity longer than half the width of one interval, dense standing, distance between two setae shorter than length of one seta. Spermatheca with ramus conspicuously longer than nodulus......................5

5. Erect elytral setae fine, piliform and pointed apically...................................... A. fodori Yunakov, 2005

- Erect elytral setae subspatulate, distinctly widened and rounded apically..........................................6

6. Appressed elytral scales apically shallowly bifid...................................... A. intermedius Yunakov, 2005

- Appressed elytral scales apically regularly rounded...........................................................7

7. Elytra slender, subparallel-sided, 1.47–1.55× as long as wide, laterally flat. Pronotum slender, 1.28–1.33× as wide as long. Elytral intervals with 2 irregular rows of erect setae................................................. A. osellai sp. n.

- Elytra short oval, with distinctly rounded sides, 1.27–1.38× as long as wide, laterally vaulted. Pronotum wider, 1.41–1.52× as wide as long. Elytral intervals with 1 regular row of erect setae.................................................8

8. Appressed scales on elytra oval, apically rounded, weakly longer than wide and weakly more slender than raised setae. Antennal funicle segment 2 1.1× as long as wide. Antennal funicle segments with long, semierect setae........ A. thracicus sp. n.

- Appressed scales on elytra narrowly drop-shaped, apically pointed, twice as long as wide and half as wide as width of raised setae. Antennal funicle segment 2 isodiametric to slightly wider than long. Antennal funicle with short, semiappressed setae................................................................................ A. cephalotes Yunakov, 2005
