description: Key to the species of Mimosticus
1 In dorsal view, neck constriction with nuchal ridge not visible (Fig. 3 A–B); eyes usually larger, in dorsal view 2.4–3.6 times as long as tempora (usually tempora appear distinctly less than half the length of eye as in Fig. 3 A–B); antennomere 4 shorter, 1.5–2.0 times as long as wide (Fig. 2 A–B)................................................................. 2
- In dorsal view, neck constriction with nuchal ridge distinct laterally (Fig. 3 C–D); eyes usually smaller, in dorsal view 1.6–2.6 times as long as tempora (usually tempora appear at least as long as half the length of eye as in Fig. 3 C–D); antennomere 4 longer, 2.2–3.0 times as long as wide (Fig. 2 C–D).............................................................. 3
2 Elytra bright metallic blue or bluish-green (Fig. 1 A); abdominal segment VIII markedly bicolored, orange to yellow in apical half, contrasting with dark metallic remainder of abdomen (Fig. 1 A); pronotum distinctly transverse (Fig. 3 A); antennomeres shorter (Fig. 2 A); eyes slightly shorter in dorsal view, 2.4–2.8 times as long as tempora (Fig. 3 A); aedeagus in parameral view: paramere wider apically compared to subapically, apex rounded (Fig. 8 A), internal sac with less pronounced sclerotized structures (Fig. 9 A). Known from Costa Rica, Panama, and scattered localities in the South American Andes.................................................................................................... M. viridipennis, Sharp
- Elytra dull, metallic greyish blue (Fig. 1 B); abdominal segment VIII not or only subtly bicolored, apical margin at most slightly paler than rest of abdomen (Fig. 1 B); pronotum about as wide as long (Fig. 3 B); antennomeres longer (Fig. 2 B); eyes slightly longer in dorsal view, 3.0–3.5 times as long as tempora (Fig. 3 B); aedeagus in parameral view: paramere gradually tapering towards the apex, apex slightly pointed (Fig. 8 E), internal sac with more pronounced sclerotized structures (Fig. 9 B). Known only from the South American Andes......................... M. tenuiformis Brunke and Solodovnikov, sp. n.
3 Elytra with bright, gold-green metallic reflection (Fig. 1 C); eyes distinctly smaller, in dorsal view 1.6–2.0 times as long as tempora (Fig. 3 C); antennomeres 7–10 wider (Fig. 2 C)................... M. aeneipennis Brunke and Solodovnikov, sp. n.
- Elytra with bright blue, bluish purple or brassy-purple metallic reflection (Fig. 1 D); eyes distinctly larger, in dorsal view 2.2–3.0 times as long as tempora (Fig. 3 D); antennomeres 7–10 narrower (Fig. 2 D) … sharpi species complex........... 4
4 Male tergite VIII with small, distinct notch (Fig. 5 A); male sternite IX with only vague constriction halfway along its length (Fig. 6 F); male tergite X with truncate apex (Fig. 7 F); internal sac of aedeagus with copulatory sclerite weakly developed and small (Fig. 9 G)..................................................... M. latens Brunke and Solodovnikov, sp. n.
- Male tergite VIII with evenly rounded apex; male sternite IX with distinct constriction forming an elongate basal ‘stem’ (Fig. 6 D–E); male tergite X with apex more rounded (Fig. 7 D–E); internal sac of aedeagus with copulatory sclerite well developed as a plate (Fig. 9 E–F, ‘b’).............................................................................. 5
5 Male tergite X less elongate, apex with setae finer and shorter (Fig. 7 D); ‘stem’ of male sternite IX broader, stem distinctly shorter than apical half (Fig. 6 D); apex of male sternite VIII more acute, narrowing at a point closer to the base (Fig. 4 D); internal sac of aedeagus with broad, emarginate copulatory sclerite (Fig. 9 E, ‘b’).... M. sharpi Brunke and Solodovnikov, sp. n.
- Male tergite X more elongate, apex with setae coarser and longer, more uniform (Fig. 7 E); ‘stem’ of male sternite IX narrower, stem nearly as long to equally as long as apical half (Fig. 6 E); apex of male sternite VIII more obtuse, narrowing at a point closer to the apex (Fig. 4 E); internal sac of aedeagus with narrow, non-emarginate copulatory sclerite (Fig. 9 F, ‘b’)..................................................................... M. pseudosharpi Brunke and Solodovnikov, sp. n.
