Species Lucicutia bradyana - Plate 6 of morphological figuresissued from : E.L. Markhaseva & F.D. Ferrari in J. Nat. Hist., 2005, 39 (15). [p.1088, Fig.6].
Male: A-B, right and left P5 (specimen identified by Hulsemann, 1966 as L. rara, from Indian Ocean (29°29'S, 48°43'E); C-D, P5 (holotype of L. rara).
Scale bars: 0.1 mm.


Species Lucicutia bradyana - Plate 7 of morphological figuresissued from : E.L. Markhaseva & F.D. Ferrari in J. Nat. Hist., 2005, 39 (15). [p.1089, Fig.7].
Male: A1-C1, right P5; A2-C2, left P5.
Scale bars: 0.1 mm.
From Indian Ocean (31°39'S, 66°04'E): A1, A2; remaining figures, specimens from South-western Pacific Ocean (57°06'S, 78°56'W).


Nota: The shape of the left and right basipod of male P5 distinguishes L. bradyana from L. grandis, but those shapes vary within a species. Among specimens studied is a male whose P5 (Fig.7 A2) is similar to that illustrated by Cleve (1904, Fig.34) in the original description. Despite this variability, the left basipod of all specimens has an elongate medially with teeth on the tip; right basipod has a distinct knob at mid-length.

The synonymy with Lucicutia rara is contested. For Hülsemann (1966, p.736) the male resembles L. grandis, longifurca and ushakovi in size and in the 3-segmented endopod of P1. It is distinguished from these species by its head armature combined with the long anal segment and the peculiar structure of P5. The species (raraL. bradyana Cleve which is doubtfully referred by Hülsemann to L. grandisSee remarks in Markhaseva & Ferrari (2005, p.1079, 1084, 1090) for Lucicutia grandis; for the authors it is a significant variability in P5 structure of males P5; shape of the left and right basipod of male P5 distinguishes L. bradyana from L. grandis, but those shapes vary within a species; despite this variability, the left basipod of all specimens of L. bradyana has an elongate projection medially with teeth on the tip; right basipod has a distinct knob at mid-length. The medial distal edge of the basipod of the left P5 of L. grandis has a saw-like, toothed margin; the medial edge of the basipod of the right P5 has a small bump.
