For Böttger-Schnack & Schnack (2013, p.21) currently belonging to the zernovi-group, is only partly resolved and requires re-examination of Sars's original materiel (see Böttger-Schnack, 2002). | | | Last update : 28/10/2022 | |
| | | | Oncaea tenella Sars is closely related to O. zernovi Shmeleva and O. bispinosa Böttger-Schnack, representing the zernovi-complex within the Oncaeidae (Böttger-Schnack & Huys 1998). The three species are very similar in body length and overall habitus, but differ in the spine count on the swimming legs (cf. Böttger-Schnack 2002, table II, III, IV). A review of the existing zoogeographical data of O. tenella showed that to date, no reliable morphological description of the species other than the initial record from the western Mediterranena Sea, near the Moroccan coast (Sars 1916) has been published and its zoogeographical distribution is unknown (cf. Böttger-Schnack 2002, p.1127).
