Brianola sydeneyensis   Hamond,  1973 (Copepod)
Organism information awaits expert curation
Class: Maxillopoda

Each abdominal segment (except the first) is fringed posteriorly by a hyaline frill which in segments two and three is fully incised into sharp spine-like structures of equal length all around the segment. On segment four the frill is only semi-incised and the depth of incision is variable. Dorsally the frill is wide with the medial portion forming a concave pseudoperculum with deep incisions. Laterally the incisions are small but become larger again midventrally. On the last segment the dorsal part of the frill is narrow and entire and forms the true operculum while laterally and ventrally the frill is narrow but fully incised, although immediately lateral to the operculum it is wider, forming the 'spines'. The abdominal ornamentation is more extensive. Also, in addition to the two longitudinal lateral rows of spinules, the caudal ramus has a diagonal ventral row of six or seven spinules.
