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 View FIG ) has a short rectangular propodus with straight fingers slightly longer than the propodus; form II ( Fig. 1C View FIG ) has an elongate subrectangular or trapezoidal propodus with long fingers which are usually curved inward.
