Heron & B.W. Frost in Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1051, Fig.20, F)]. Female (from NE Pacific): F, pediger 4 posterior corner and urosome (dorsal; scale bar: x). Scale bars: 0.1 mm, see figures 3, 4, 5, 10 of Heron and Frost, 2000 for Oncaea canadensis and Oncaea insolita.

issued from : G.A. Heron & B.W. Frost in Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1022, Fig.2, I]. Female: P2-P4 endopod terminal ''spine set'' (combination of the lengths, shapes, and position of the three or two terminal spines on the endopods of swimming legs 2-4 , from left to right in figure, for different Oncaea' species). Nota: endopod of P2 with subterminal spine extending to less than half the length of terminal spine.

(W Egyptian coast) | | | N: | 7 | | | Lg.: | | | (675) F: 0,48-0,42; M: 0,46-0,38; (681) F: 0,42; (848) F: 0,42-0,47; M: 0,36-0,38; {F: 0,42-0,48; M: 0,36-0,46} | | | Rem.: | bipolar species. Sampling depth (Antarct.) : 0-125 m. For Heron & al. (1984, p.478), the species is similar to O. setosa, but may be distinguished by differences in the relative prosome/urosome lengths, the urosome measuring more than one-half the prosome length for O. lacinia and approximately one-half for O. setosa. O. lacinia lacks a cluster of spinules on A2 segment 2 and differs by the relatively long setule representing P6 of the female. P5 of O. setosa is a free segment while that of O. lacinia is not dorsally delimited. The setae lengths of P5 are slightly variable for both species, but relative differences between lengths is less for O. lacinia (1:2), compared to 1:3 for O. setosa. O. lacinia also resembles but may be distinguished from the species which Sars (1918) identified as O. minuta Giesbrecht, 1892 (= Triconia minuta; Sars's species differs from Giesbrecht's original desctription by the P4 endopod lacking a terminal conical projection. | | | Last update : 16/01/2018 | |
