Treatment

Cenomanocarcinus inflatus Van Straelen, 1936 View in CoL ( Fig. 1A, B, E, F View FIG )

MATERIAL EXAMINED. — Upper Cenomanian , Le Mans, Butte de Gazonfier, lectotype ( Van Straelen 1936: pl. 4, fig. 8), dorsal carapace (ex. Hébert Colln, MNHN J08587 View Materials ) ; paralectotype ( Fig. 1A, B View FIG ), dorsal carapace (44 × 52 mm), width measured exclusive of both long epibranchial spines (broken) ( MNHN R05504) ; dorsal carapace ( MHN LM 3804 ) ; dorsal carapace (27 × 38 mm), with partially preserved epibranchial spines (estimated width at least 40 mm inclusive of complete epibranchial spines) ( MHN LM 3806 ) ( Breton & Collins 2007: fig. 5) ( Fig. 1E, F View FIG ) .

OCCURRENCE. — Upper Cenomanian.

Remarks

The manuscript name Necrocarcinus inflatus A. Milne-Edwards quoted by Guillier (1886: 244), consequently a nomen nudum, appeared only with a figure in Boule & Piveteau (1935: 392, fig. 670); published after 1930 and not being accompanied by a description, it is not an available name ( ICZN 1999: Article 13.1.1). The species name was validly introduced by Van Straelen (1936: 37- 39, pl. 4, fig. 8), who established the new genus Cenomanocarcinus Van Straelen, 1936 , with C. in-

flatus as type species.

Breton & Collins (2007: 18) have recently designated as lectotype of C. inflatus the specimen figured by Van Straelen (1936: pl. 4, fig. 8) and labelled “La Butte de Gazonfier au Mans” (ex. Hébert Colln, MNHN J08587 View Materials ). A smaller, more complete individual ( Fig. 1E, F View FIG ) from the same locality, preserves teeth of the carapace margin (generally broken in fossils) ( Breton & Collins 2007: fig. 5) and a trilobed front ( Fig. 1F View FIG ). Cenomanocarcinus inflatus , supposed to have a rounded carapace (as in paralectotype MNHN R05504) ( Fig. 1B View FIG ), in fact possesses a long epibranchial tooth, followed by two posterolateral teeth including subdistal ones at the extremity of the branchial ridge ( Fig. 1E View FIG ).

The ventral surface and walking pereiopods of C. inflatus are unknown; the cheliped of the paralectotype was figured by Breton & Collins (2007: fig. 4).
