( Fig. 1A–D )

Enoploclytia tepeyacensis Vega, Garassino & Zapata-Jaime in Vega et al. 2013: 209–211, figs. 2 [unavailable].

Type material. HOLOTYPE: MUZ-824, carapace preserving dorsal surface, carapace length 96.8 mm, width 53.2 mm, height 44.2 mm, early Campanian beds of the Austin Group (Dessau Formation) near Jiménez , Coahuila, NE Mexico . PARATYPE: MUZ-825, carapace preserving only left side, length 65.9 mm, height 32.1 mm, same locality as holotype.

Diagnosis. Carapace elongate and cylindrical; deep cervical groove, gently inclined, intercepting dorsal margin at an angle of ca. 60°; dorsal midline of the carapace without intercalated plate; deep, very reduced gastro-orbital groove; deep, sinuous postcervical groove, intercepting dorsal margin at an angle of ca. 50°; deep, very short branchiocardiac groove, not joining postcervical groove, not extending ventrally below mid-height, intercepting dorsal margin at an angle of ca. 60°; deep hepatic groove, strongly convex ventrally at intersection with postcervical groove and strongly concave dorsally at intersection with cervical groove; deep inferior groove strongly convex posteriorly; all regions of the carapace covered dorsally with strong tubercles, becoming reduced in size ventrally.

Etymology. The trivial name alludes to El Tepeyac area, Coahuila, where the Mexican specimens were discovered. Remarks. A full description and figures of Enoploclytia tepeyacensis , and stratigraphic account are given by Vega et al. (2013).
