Plate 1 issued from : F. Krsinic in J. Plankton Res., 2005, 27 (6). [p.609, Fig.1]. Female (from 43°70' N, 17°03'02''E): A-B, habitus (dorsal and lateral, respectively); C, urosome (dorsal); D, genital double-somite (lateral, right side).
Cephalosome and 1st pedigerous somite fused. Caudal rami asymmetrical, longer than wide, right ramus slightly longer than left and about twice as long as wide; each ramus with 4 terminal setae (III-VI), small seta VII on inner border of caudal ramus; attachment sites of inner setae asymmetrical developed, with left seta originating anterior to that of right ramus; terminal setae II-VI with fine setules along their lengths.
Plate 2 issued from : F. Krsinic in J. Plankton Res., 2005, 27 (6). [p.610, Fig.2]. Female: A, urosome (lateral); B, genital double-somite (ventral); C, anterior part of the head with labrum (ventral); D, A1.
Nota: A1 24-segmented, reaching almost end of anal segment. Rostral area rounded with a very small protuberance ventrally. labrum with 6 secretory pores on anterior surface, distal margin spinulose, and each lateral lobe with spinulose patch. Genital double-somite with genital area symmetrical, located medio-ventrally; operculi fused, genital apertures and seminal receptacles paired; row of small spinules on each side of genital double-somite.
Plate 3 issued from : F. Krsinic in J. Plankton Res., 2005, 27 (6). [p.611, Fig.3]. Female: A, A2; B, Md; C, Mx1; D, Mx2; E, Mxp.
Nota: Exopod of A2 7-segmented; endopod 2-segmented. Endopod of Md 2-segmented, exopod 5-segmented with setal formula 1, 1, 1, 1, 2. Mx1 with praecoxal arthrite bearing 9 + 4 elements posteriorly; coxal epipodite armed with 8 setae and coxal endite with 3 setae; proximal basal endite with 4 setae, distal basal endite with 5 and basal exite with 2 setae; exopod bearing 11 setae; endopod 3-segmented, setal formula 3, 4, 7. Endopod of mxp 6-segmented, armature formula 2, 4, 4, 3, 3+1, 4.
Plate 4 issued from : F. Krsinic in J. Plankton Res., 2005, 27 (6). [p.612, Fig.4]. Female: A-D, P1 to P4; E, P5.
Plate 5 issued from : F. Krsinic in J. Plankton Res., 2005, 27 (6). [p.614, Fig.5]. Male: A-B, habitus (dorsal and lateral, respectively; C, P5; D, right P5 (lateral); E, terminal part of left P5.
Nota: Rostral area and labrum, A2, mouthparts and swimming legs P1-P4, all identical to female. Urosome 5-segmented, proportional lengths of urosomites and caudal rami 36 : 15 : 13 : 13 : 10 : 13 = 100. Genital segment asymmetrical, with genital aperture on the left. Posterior margins of urosomites 2-4 fringed with very fine spinules. P5 uniramous, strongly asymmetrical; left leg elongate, 5-segmented, proportional lengths of segments 18 : 27 : 16 : 33 : 6 = 100.; right P5, small, reduced 3-segmented with proximal segment representing coxa and incorporated intercoxal sclerite. caudal rami as in female.
Plate 6 issued from : F. Krsinic in J. Plankton Res., 2005, 27 (6). [p.613, Table I]. Armature formula Female and Male swimming legs P1 to P4.
For Krsinic (2005, p.613) this species displays several primitive features for the family Stephidae, including 13 armature elements on the praecoxal arthrite and 2 setae on the basal exite of the Mx1, contrary to remaining Stephidae which are armed with a single seta on the basal exite. The salinity in water column below 5 m depth was 37-38 and temperature ± 15°C.
