Ref.:
Bradford-Grieve, 2004 b (p.622, figs.F,M, tab.1)
Species Xanthocalanus longispinus - Plate 1 of morphological figuresissued from : J.M. Bradford in N.Z. Jl Mar. Freshw. Res., 2004, 38 (4). [p.623, Fig.1].
Female (from SE North Island, New Zealand): A, habitus (lateral right side); B, idem (dorsal); C, urosome (ventral, flattened); D, genital segment (lateralright side); E, rostrum (anterior view); F, P5 (posterior); G, idem (anterior).

Nota: Head and 1st thoracic segment partially separate ( on dorsal surface and round onto the lateral surface), 4th and 5th fused (fusion line visible only dorsally). Urosome surfaces (except anal segment) covered in very small semicircular thickenings (probably represent place of attachment of scales). Anal segment very short (not visible on dorsal surface. A1 (24-segmented) extending slightly beyond posterior border of genital segment.
