Species Gaussia asymmetrica - Plate 1 of morphological figuresissued from : T.K.S. Björnberg in Hydrobiologia, 1988, 167/168. [p.352, Fig.1, A, B, C, G, H];
Female (from NE San Fernando de Noronha): A, habitus (dorsal); B, forehead (lateral); ; C, anal operculum; G, proximal part of a caudal seta (enlarged from A: arrow); H, luminous gland openings in the anal segment and caudal ramus.

Nota: Forehead anteriorly flat in dorsal view; in lateral view it lacks a depression just below the anterior outline of the head (compare fig.1B with fig.1E Gaussia princeps in Björnberg & Campaner, 1988, p.352). The left posterior metasomal corner is slightly curved outwards, whereas the right is straight.
