Species Oncaea ovalis - Plate 1 of morphological figuresissued from : R. Böttger-Schnack in Cah. Biol. Mar., 2005, 46. [p.187, Fig.11].
Female (from Adriatic Sea): A, habitus (dorsal); B, idem (lateral right side); C, urosome (dorsal); D, idem (lateral left side, caudal setae IV and V omitted); E, A1 (question mark on segment 4 indicating position of aesthetasc in quetion, small pit); F, caudal ramus (dorsale); G, P5 (dorsal).

Nota: Proportional lengths (%) of urosomites and caudal rami 7.9:48.0:10.5:8.7:12.7:12.2. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 5.5:19.6:48.0:11.4:4.4:11.1. Genital double-somite oval, twice as long as maximum width (measured in dorsal aspect) and 1.5 times longer than postgenital somites combined; Anal somite about as wide as long, slightly longer than caudal rami. Caudal ramus 1.9 times longer than wide.
