Key to the species of Crataraea

1 Pronotum less transverse, approximately 1.35 times as broad as long and 1.3 times as broad as head ( Figs 1-2 ). Elytra bright reddish, strongly contrasting with the brown to dark-brown pronotum. Antennae with antennomeres IV-X less transverse ( Fig. 2 ).: unknown.: spermatheca with less slender and shorter distal portion ( Fig. 4 ). Uzbekistan. .................................................................................... C. solskyi (EPPELSHEIM) - Pronotum more transverse, approximately 1.5 times as broad as long and 1.4 times as broad as head. Elytra of similar coloration as pronotum, but often reddish at suture and/or at posterior margin. Antennae with antennomeres IV-X more transverse.: spermatheca with more slender and longer distal portion..................................................2

2 Head, pronotum, and abdomen with very shallow microsculpture and rather glossy. Antennae shorter and with more transverse antennomeres IV-X.: sternite VIII posteriorly more broadly and less strongly produced ( ASSING 2014: figure 10); median lobe of aedeagus shaped as in ASSING (2014: figures 4-6).: spermatheca shaped as in ASSING (2014: figure 7). China: Qinghai. Myrmecophilous; associated with Formica chinensis. ...................................................................................... C. myrmecophila ASSING

- Head, pronotum, and abdomen with pronounced microsculpture; head and pronotum nearly matt. Antennae longer and with less transverser antennomeres IV-X.: sternite VIII posteriorly more acutely and more strongly produced; median lobe of aedeagus shaped as in KLIMASZEWSKI et al. (2013: figures 192a-b).: spermatheca shaped as in KLIMASZEWSKI et al. (2013: figure 192c). West Palaearctic region; adventive in North America. ................................................................................... C. suturalis (MANNERHEIM)
