TYPE SPECIES. — Necrocarcinus quadriscissus Noetling, 1881 by monotypy  Noetling 1881: 368, pl. 20, fig. 4a, b); senior synonym of Dromiopsis ubaghsi Forir, 1889 ( Forir 1889: 452, pl. 14, fig. 3); upper Maastrichtian of Maastricht.

Remarks

Wright (1997: 135) was “inclined to abandon the distinction of the two subgenera”, based on post-rostral slits found in the type species of both Paranecrocarcinus and Pseudonecrocarcinus , thus a not really distinctive feature of the latter. According to Fraaije (2002: 916) “ Pseudonecrocarcinus has thus lost its validity as a genus”, since it is a junior synonym of Paranecrocarcinus . Schweitzer et al. (2003a: 32, 36) misinterpreted Fraaije’s words and regarded them as separate genera considering that “the possession of these carapace slits is highly distinctive” without realising that both genera possess them. Concludingly Wright (1997), Fraaije (2002), and Schweitzer et al. (2003a) agreed on the synonymy.

Thus Pseudonecrocarcinus stenzeli Bishop, 1983 ( Bishop 1983a: 49, fig. 8B, pl. 1, figs 3-5; 1986: 136, table 1), lower Albian of Texas, has to be assigned to Paranecrocarcinus .
