Cymbasoma tharawalorum  Suarez-Morales & McKinnon, 2016   (F)
Suarez-Morales & McKinnon, 2016 (p.110, Descr. F, figs. F, Rem.)
Espèce Cymbasoma tharawalorum - Planche 1 de figures morphologiquesssued from : E. Suarez-Morales & A.D. McKinnon in Zootaxa, 2016, 4102. [p.111, Fig.64].
Female (from 38°4.670'S, 151°9.100'E): A, habituis (lateral); B, cephalic region (lateral); C, same (ventral); D, P2 with intercoxal sclerite (arrow indicates expanded outer margin of 1st and 2nd endopodal segments); E, P1 with intercoxal sclerite; F, P3 with intercoxal sclerite.
Scale bars: A = 200 µm; B-F = 100 µm.

Nota: Cephalothorax representing about 57 % of total body length.
- Midventral oral papilla protuberant, located at 26 % of cephalothorax length.
- Pair of relatively small ocelli, pigment cups moderately developed, medially separated, weakly pigmented on reduced inner area; ventral cup larger than lateral cups.
- Frontal sensilla absent.
- Urosome consisting of 5th pedigerous somite, genital double-somite and anal somite, representing 23 % of total body length. Relative lengths of urosomites 33.5 : 42.8 : 23.7 = 100.
- Anal somite with ventral protuberance.
- Caudal ramus subrectangular, 1.6 times longer than wide, armed with 3 subequally long, sparsely setulated caudal setae.
- Ovigerous spines paired, relatively short, 45 % of total body length; spines basally separated, one spine slightly shorter.

Espèce Cymbasoma tharawalorum - Planche 2 de figures morphologiquesIssued from : E. Suarez-Morales & A.D. McKinnon in Zootaxa, 2016, 4102. [p.112, Fig.65].
Female: A, habitus (dorsal); B, right A1 (dorsal); C, urosome (ventral); D, same enlarged, lateral view, arrow indicates ventral expansion of anal somite; E, urosome (dorsal).
Scale bars: A = 200 µm; B, C, E = 100 µm; D = 50 µm.

Nota: A1 relatively short, representing about 16.5 % of total body length, and 30 % of cephalothorax length; 4-segmented, segments 3 and 4 compressed; relative length of short distal segment 42.5 %.
- P5 medially separated, bilobate, outer (exopodal) lobe elongate, distally truncate, reaching about 1/3 length of genital double-somite, armed with 2 subequally long setae on distal position. Inner lobe represented by small, rounded process inserted at middle inner margin of main lobe.

Espèce Cymbasoma tharawalorum - Planche 3 de figures morphologiquesssued from : E. Suarez-Morales & A.D. McKinnon in Zootaxa, 2016, 4102. [p.113].
Female: Armature formula of swimming legs P1 to P4.

Type locality: 38°4.670' S, 151°9.100' E.

* Body length measured from the anterior end cephalothorax to the posterior end of the anal somite.
Rem.: For Suarez-Morales & McKinnon (2013, p.113) the species is assignable to the agoense Group. It differs from C. agoense in the shape and structure of the P5 inner lobe; both setae on the outer lobe are distal in C. Tharawalorum whereas 1 is distal and the other is subdistal in C. agoense (Sekiguchi, 1982: fig.6F), they differ also in the body proportions and the 5th pedigerous somite.
