Muderongia tomaszowensis
Muderongia tomaszowensis Alberti, 1961; Emendations: Monteil, 1991b, p.477; Riding et al., 2001, p.31.
Taxonomic senior synonym: Wetzeliella? (as Phoberocysta) neocomica, by implication in Monteil (1991b, p.476), who considered Muderongia tomaszowensis to be the senior name — however, this synonymy has not been generally followed;
Taxonomic senior synonym: Muderongia simplex, according to Jain and Khowaja-Ateequzzaman (1984, p.39) and Poulsen (1996, p.59) — however, Riding et al. (2001, p.31) retained Muderongia tomaszowensis.
Holotype: Alberti, 1961, pl.2, fig.12; lost according to Riding et al. (2001, p.31).
Lectotype: Alberti, 1961, pl.2, fig.13; Riding et al., pl.1, fig.7; designated (as a neotype) by Riding et al. (2001, p.31).
Stratum typicum: Valanginian
Emended diagnosis: Monteil, 1991, p. 477
Cysts proximate to proximochorate, compressed dorsoventrally, two-layered, cornucavate to delphicavate or circumcavate. Pericyst ceratioid, symmetrical, with 4 prominent horns: 1 apical (axial, type AP I); 2 subequal lateral (axial, type L I), indented; 1 antapical (axial, type ATP I). Left lateral horn may be slightly more reduced than the right one. Horns normal with distal extremities closed and rounded; proximal extremities narrow, except for the antapical horn which may be wider A small rounded bulge can be present in right antapical position (Pl. 3, figs. 1, 2). Endocyst oval to rhombic. Periphragm thin, psilate to scabrate; periphragm may be ornamented by verrucae or processes (stages I to IV). Endophragm thin, psilate to granulate Archeopyle apical, type (4A), with angular margin. Parasulcal notch marked. Operculum free. Paratabulation indicated by archeopyle, by low parasutural ridges or septa, and more or less clearly expressed by distribution and type of processes (stages I to IV), when those are present. Occasionally, periphragm showing penitabular verrucae. Formula:?pr, 4", 0a, 6", 6c, 6""", 1p, 1"""". Pericingulum marked by indentation of lateral horns and by parallel transverse structures. Perisulcus marked by parasulcal notch offset. Parasulcal area not observed.
Dimensions of the holotype (with operculum): 140 Ám x 112 Ám (overall L x I).
