Type species

Scalpellum recurvitergum Gruvel, 1900 (see redescription in Young, 1998).

Diagnosis

Inframedian latus waisted, hourglass-shaped, umbo central to nearly basal. Well-defined margins contact the scutum and upper latus. Contact between carinolatera usually flat, symmetrical. Rostrum tiny, oval, or rarely absent. Apex of scutum, acuminate, incurved. Upper latus overlaps scutum, fitting into notch in scutum. Scutum trapezoidal, basal–occludent angle about 80°, tergal–upper latus angle 100–115°.

Included species

Scalpellum australicum Hoek, 1883 , Scalpellum novaezelandiae Hoek, 1883 , Scalpellum recurvitergum Gruvel, 1900 , Scalpellum striolatum G.O. Sars, 1877 , Scalpellum hispidum G.O. Sars, 1890 , Catherinum anglicum sp. nov. (Campanian, Cretaceous, UK), and Arcoscalpellum singletoni Withers, 1953 (Miocene, Balcombe Bay, Australia).

Remarks

As redefined here, Catherinum includes many of the species included in Verum by Zevina (1981). As noted by Young (2007), Catherinum fall into several distinct morphological groups. Although not dealt with here, many of the taxa assigned to Annandaleum (e.g. with strikingly reduced plates, such as Annandaleum japonicum Hoek, 1883 ), have an hourglass-shaped inferior median latus, at least in the juvenile stages, and are likely to be derived from species of Catherinum by plate reduction. Planoscalpellum Zevina, 1978b is a Catherinum- like form in which the upper latus umbo is unusually low on the scutum.
