TYPE SPECIES. — Macrourites modestiformis Schlotheim, 1822, by subsequent designation of Glaessner (1929).

EMENDED DIAGNOSIS. — Fusiform intercalated plate; deep cervical groove, joined to dorsal margin and to antennal groove; short gastro-orbital groove originating as a slight median inflexion of cervical groove; postcervical and branchiocardiac grooves subparallel; postcervical groove joined medially to branchiocardiac groove (with a short ventral extension); branchiocardiac groove strongly inclined, joined to hepatic groove; concavo-convex hepatic groove, joined to cervical groove; inferior groove convex posteriorly, joined to hepatic groove; marked ω bulge; cephalic region with two divergent rows of tubercles: orbital row with strong distal spine and antennal row with strong distal antennal spine; chelate P1-P3; P1 chelipeds without prominent spines and with homogeneous ornamentation; P1 propodus dorso-ventrally compressed with narrow inner and outer margins; P1 with narrow dactylar bulge; fingers longer than P1 propodus, equal in length, narrowing gradually to distal extremity; index wider than dactylus.

COMMENTS

Some species show short P1 fingers such as Eryma modestiforme or E. punctatum Oppel, 1861, and other species show long P1 fingers such as E. bedeltum (Quenstedt, 1857) or E. ventrosum (Meyer, 1840). Following Hyžný et al. (2015), we distinguish two forms chelae. Form I (Fig. 1B) has a short rectangular propodus with straight fingers slightly longer than the propodus; form II (Fig. 1C) has an elongate subrectangular or trapezoidal propodus with long fingers which are usually curved inward.
