Taxonomy

Citation: Trisulcus Popofsky 1913
Taxonomic rank: genus
Basionym: Trisulcus
Type species: Trisulcus triacanthus Popofsky 1913
Taxonomic discussion: [Trusulcus synonomized to Botryopera by Petrushevskaya 1975 but Botryopera is a cannobotryid, clear in definition from Haeckel. Description of Trisulcus is of form closely related to the lophophaenid genus Amphiplecta. Synonomy of Petrushevskaya rejected here - dbl]

Catalog entries: Trisulcus

Original description: Tripocyrtiden mit zweiteiliger, basal offener Schale, die im Innern des Thorax drei Stacheln besitzt, welche nur bis zur Schalenwandung verlaufen, aber nicht über diese hinausragen. Kopf apikal geschlossen.


Translated description: Tripocyrtidae with a basally open, two-segmented, shell that has inside the thorax three spines, developed only towards the thoracic wall, but not protruding outside. Cephalis closed upwardly. (In German. Translated by J.P.C.)]
