1b. Carapace as long as wide 7
2a. Augenrest longer than wide 3
2b. Augenrest wider than long, with rounded, posterior angle, assymetrical along the horizontal axis [carapace much longer than wide; lateral borders between outer orbital spine and cervical groove covered with tubercles; behind cervical groove borders smooth, parallel; rostrum short, narrow, with truncated edge; projection of orbital margin intercepts longitudinal axis at angle c. 75o; spines on the upper orbital margin present; hepatic tubercles present; groups of hepatic pits present; three pairs of pits (I-III, compare Figure 2.1) present] E. aequilatus
3a. Rostrum incised in the middle 4
3b. Rostrum without incision 5
4a. Pairs of pits: I-III present [pair of groups of hepatic pits present; lateral borders smoth; hepatic tubercles weakly visible; augenrest 1.75x longer than wide, symmetric along horizontal axis; projection of orbital margin intercepts longitudinal axis at angle c. 60o (Figure 2.3)] E. guenteri n. sp.
4b. Pairs of pits I-III absent [only the tip of the mesogastric region is distinct; posterior margin of carapace not incised, and not surrounded by with a furrow] E. rostratus
5a. Species relatively small (about 4 mm max. carapace width) 6
5b. Species relatively large (about 17 mm max. carapace width) [rostrum short; hepatic tubercles faint; groups of hepatic pits present; lateral margis of carapace covered with small serrations; augenrest 1.4-1.5x longer than wide, symmetric along the horizontal axis; projection of orbital margin intercepts longitudinal axis at about 55 degree angle; pairs of pits: I-III absent (Figure 2)] E. grandis
6a. Rostrum long, broad; lateral borders of the carapace are smooth; carapace narrowing posteriorly; hepatic tubercles small; groups of hepatic pits faint; augenrest barely longer than wide (1.1x), subtriangular, asymmetric along the horizontal axis, with an elevated posterior angle; projection of orbital margin intercepts longitudinal axis at about 50 degree angle; pairs of pits I-III absent (Figure 2) E. rotundus n. sp.
