Quasihermanites ? sp. 1

Fig. 8 E–F

Material examined

BRAZIL: Estre outcrop, Rosário do Catete Municipality, Sergipe State (samples MP-1423 and MP- 1424), approximate coordinates 10°41' S, 37°02' W.

Measurements

Hypotype (CP-715): left valve: length = 0.43 mm, height = 0.25 mm.

Hypotype (CP-766): right valve: length = 0.38 mm, height = 0.23 mm.

Remarks

The generic diagnosis follows Gründel (1964) and the suprageneric diagnosis follows Gründel (1966). The figured specimens are apparently less ornamented than other species of Quasihermanites Gründel, 1964 , especially with regard to its characteristic lateral ribs ( Kuznetsova 1961; Gründel 1964; Donze 1965; Pokorný 1973; Colin 1974; Babinot et al. 1985a; Babinot & Colin 2011). The probable reason for that would be diagenesis, similar to that observed in the type material of Quasihermanites spiralus Schudack & Schudack, 2000 ( Schudack & Schudack 2000). Therefore, the present authors classify it questionably as Quasihermanites .
