Genus Euglypha Dujardin, 1841
  
Diagnosis: test elongate ovoid or pyriform, composed of overlapping plates, usually arranged in longitudinal rows. Aperture always with denticulate mouth plates.

Remarks: This is a simplified key with only some main types. Euglypha is a large and common genus with numerous species; many species are hard to identify and may be part of species complexes. Recently (2001) a new genus Scutiglypha has been created, but there is no unique feature that separates it clearly from Euglypha.
