Cymbasoma clairejoanae  Suarez-Morales & McKinnon, 2016   (M)
Ref.:
Suarez-Morales & McKinnon, 2016 (p.103, Descr. M, figs. M, Rem.)
Espèce Cymbasoma clairejoanae - Planche 1 de figures morphologiquesIssued from : E. Suarez-Morales & A.D. McKinnon in Zootaxa, 2016, 4102. [p.104, Fig.60].
Male (from 19°16.500'S, 146°48.500'E): A-B, habitus (dorsal and lateral, respectively); C, cephalic region (ventral) showing protuberant frontal process (arrow); D, same (dorsal).
Scale bars: A, B = 200 µm; C, D = 50 µm.

Nota: Cephalothorax representing 44 % of total body length.
- Midventral oral papilla weakly developed, located at 27 % of cephalothorax length;
- Cephalic region protuberant in dorsal view. Forehead area strongly produced forming lumpy medial crest flanked by few wrinkles (arrowed in fig.60C, D).
- Pair of dorsal ocelli, moderately developed; pigment cups relatively large. Ocelli separated by the length of less than half an eye diameter, faintly pigmented. Ventral ocellus noticeably larger than lateral cups.
- No sensilla observed between antennulary bases.
- A1relatively long, representing 36 % of total body length, and 72 % of cephalothorax length, 5-segmented, with segment 5 located distal to geniculation. Length ratio of segments 11.4 : 27.8 : 12 / 26.6 : 22.2 = 100.


Espèce Cymbasoma clairejoanae - Planche 2 de figures morphologiquesIssued from : E. Suarez-Morales & A.D. McKinnon in Zootaxa, 2016, 4102. [p.105, Fig.61].
Male: A-B, urosome and genital complex (ventral and lateral, respectively); C, same (dorsal); D, right A1 (dorsal); E, P1 with smooth intercoxal sclerite; F, P3 with intercoxal sclerite.
Scale bars: A-C, E, F = 100 µm; D = 50 µm.

Nota: Urosome consisting of 5th pedigerous somite, genital somite (genital complex), preanal somite and anal somite.
-bGenital complex represented by pair of moderately divergent, symmetrical slender, digitiform genital lappets resembling an inverted ''U'' (lappet surface smooth).
- Anal somite noticeably long, about 2 twice as long as preanal somite in dorsal view, comprising 33 % of urosome length; constriction in proximal 1/3 of anal somite visible in ventral aspect, cuticular hyaline frill absent.
- Caudal rami subquadrate, about 1.1 times as long as wide, about 0.7 times as long as anal somite. Each ramus with 4 caudal setae.


Espèce Cymbasoma clairejoanae - Planche 3 de figures morphologiquesIssued from : E. Suarez-Morales & A.D. McKinnon in Zootaxa, 2016, 4102. [p.106].
Male: Armature formula of swimming legs P1 to P4.

Loc:
NE Australia (Ross Creek, Townsville)

Type locality: 19°16.500' S, 146°48.500' E.
N: 1

(1198)* M: 0,28; {M: 0,28}

* Total body length measured from the anterior end of cephalothorax to the posterior end of the anal somite.
Rem.: After Suarez-Morales & McKinnon (2016, p.106) the species is represented by the only Australian male Cymbasoma with 4 caudal setae, a strongly protuberant frontal area, and a constricted anal somite. A similar genital complex is known only in C. pallidum Isaac, 1974.
