The Ophryotrocha labronica group (Annelida: Dorvilleidae) — with the description of seven new species Author Paxton, Hannelore Author Åkesson, Bertil text Zootaxa 2010 2713 1 24 journal article 10.5281/zenodo.199650 04935f31-4d00-404d-9016-4831c3313c83 1175-5326 199650 Ophryotrocha olympica nom. nud. Table 1 Ophryotrocha olympica nom. nud. Pleijel & Eide, 1996 : 648 . Diagnosis. Prostomium with moderately long, tapering antennae, palps absent; two distinct eyes, not medially connected; parapodia uniramous, lacking dorsal and ventral cirri; dorsal single rosette glands on posterior segments; detail of mandibles and maxillae unknown, K-forceps, right bidentate, left falcate; gonochoristic; chromosomes 2n = 6; diameter of eggs 165 µm; released larvae with 3 chaetigers. Remarks. The specimens were collected in June 1978 in the Mukkaw Bay in the Makah Indian Reservation, about 8 km south of Cape Flattery on the Olympic Peninsula, Washington state, in gravel from a depression in the rocky shore, mid to high intertidal zone. Crossing experiments demonstrated that this species is a typical member of the O. labronica group, as has been confirmed by electrophoresis ( Pleijel & Eide 1996 ). In routine culture the adult females had 17-19 chaetigers with a maximum of 22. Males were smaller, 14-15 chaetigers and an observed maximum of 17. Adults have small, segmentally arranged brown-red pigment spots. Since the culture no longer exists and no material was preserved, this species remains indeterminate. Distribution. Western North Pacific: Mukkaw Bay, Olympic peninsula, Washington, USA .
