Brachycalanus flemingeri  Ferrari & Markhaseva, 2000   (F)
Ref.:
Ferrari & Markhaseva, 2000 a (p.1065, Descr.F, figs.F); Bradford-Grieve, 2004 b (p.645, tab.2)
Espèce Brachycalanus flemingeri - Planche 1 de figures morphologiquesissued from : F.D. Ferrari & E.L. Markhaseva in Proc. Biol. Soc. Washington, 2000, 113 (4). [p.1066, Fig.1].
Female (from off Kona, Hawaï): A, habitus (lateral right side); B, forehead (ventral); C, rostrum (anterior-ventral); D, posterior part of cephalothorax and urosome (lateral right side); E, urosome (ventral); F, genital complex (ventral); G, posterior part of cephalothorax and genital complex; H, urosome (dorsal).
Bars: 0.1 mm.
Nota: Head and 1st thoracic segment separate, 4th and 5th separated but not well articulated. 3rd thoracic segment with 2 sensilla laterally, ventrallonger; 4th with 1 short dorsal sensilla laterally. genital segment and following 2 urosomal segments with small, scale-like spinules. Rostrum, subdiivided plate with 2 filaments. A1 (24-segmented) reaching the 2nd thoracic segment. Caudal rami with 4 large, terminal setae, 1 small medial-dorsal seta, and 1 small lateral-ventral seta.

For the authors the true first thoracic somite is corresponding to Mxp in the publication as the genital complex incoporates the last thoracic somite and the first urosomal somite (= genital complex).
