Diagnosis
ReferenceDiagnosis
J. Vannier 1987Ostracodes de la sous-famille Tetradellinae SWARTZ, 1936, g6n6ralement quadrilob6s. Obsolescence possible des sillons S 1 et $3, voire de $2. Fusion fr6quente de L3 et L4. L1 prolong6 par un processus ant6rodorsal de forme plus ou moins h6lico~'dale (<< sperum >> ou << speral process >> sensu Jaanusson, 1957), bord6 sur toute sa longueur ou non par une rang6e de lamelles (fimbriae) ou d'6pines. Connexion ventrale des lobes sous forme d'un 6pais bourrelet histial arrondi ou saillant (<< ridge-like histial flange >>). Collerette v61aire 6troite et concave chez les tecnomorphes, tr~s 61argie chez les h6t6romorphes et formant un dolon de taille variable le long du bord ant6rieur et/ou ventral des valves. Surface des valves g6n6ralement lisse mais parfois r6ticul6e.
