Remarks.—“Entomozoaceans” (= Entomozoacea sensu Přibyl, 1951) have long been regarded as myodocopes (e.g., Sylvester-Bradley 1961), but by their signature “finger-print” ornament and in generally lacking a rostrum and rostral incisure they are considered to be the most atypical of all of the ostracod groups that have traditionally been assigned to the Myodocopa (see discussion in Siveter and Vannier 1990; Kornicker and Sohn 2000). However, the discovery of a Palaeozoic myodocope with preserved soft-parts, Colymbosathon ecplecticos Siveter Sutton, Briggs, and Siveter, 2003 from the Silurian of England, has yielded new evidence to support a myodocope affinity for “entomozoaceans”. Colymbosathon ecplecticos has a very similar valve outline and lobal/sulcal morphology to that of Richteria migrans and both taxa lack a rostrum and rostral incisure.

Herein the concept of the “Entomozoacea” is used in its widespread and traditional sense, even though the type species of the type genus of the “ Entomozoidae ”, namely Entomozoe tuberosa ( Jones, 1861) from the Silurian of Scotland, is known to be an entirely different form of ostracod (assigned to the myodocope superfamily Bolbozoidea Bouček, 1936 ; see Siveter and Vannier 1990 for discussion and recommendations).
