Checked: verified by a taxonomic editorTaxonomy Conaea aestus Oliveira, 1946 is regarded as species inquirenda in the family Oncaeidae based on the following grounds: in the original description of the species (1) the leg armature of the swimming legs is not given, which is required to verify the generic classification; (2) the armature of the antenna (fig. 7.2) is incomplete, lacking important diagnostic characters; (3) the basis of the maxilliped is very elongate, which is not typical for species of Conaea (except for C. rapax); (4) the caudal rami are very elongate (short in typical Conaea, including C. rapax) and the dorsal expansion surrounding the base of caudal seta VII, which is typical for all Conaea species, is not apparent; (5) the proportional lengths of urosome segments are different from typical Conaea species, but resemble C. rapax (cf. Heron, 1977). Some authors have synonymized C. aestus Oliveira with C. rapax Giesbrecht, however, this course of action is not followed here, because - in addition to the arguments given above - (1) the total body length of C. aestus (0.5 mm) is much smaller than that of C. rapax, which measures between 0.9 - 1.2 mm, and (2) the depth of occurrence of this species in the surface layers does not correspond to the depth distribution of C. rapax, which is typically found in the bathypelagic zone.

Some of the morphological characters of Oliveira´s species appear to be similar to Monothula subtilis (Giesbrecht), which was redescribed in detail by Böttger-Schnack & Huys, 2001. However, as no type material of Conaea aestus was deposited in a museums´s collection, a re-examination of the specimen and clarification of its taxonomic status is not possible. [details]
