Classification and/or Status

Irregularia; Cassiduloida; 'Gitolampadids'.

Subjective junior synonym of Gitolampas Gauthier, 1889.


Kier (1962, p. 203) states that Santeelampas is very similar to Gitolampas in its peristome, floscelle, and position and shape of its periproct. It differs only in that it has slightly narrower petals and a more inflated test. Such characters are not worthy of generic distinction. Kier's (1962, text-fig. 168) drawing of a phyllode is not typical of the species, being broader than those on specimens we examined.
