Espèce Triconia umerus - Planche 1 de figures morphologiquesissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.93, Fig.24].
Female (from Red Sea): A, habitus (dorsal [a, genital aperture and part of genital double-somite, showing surface ornamentation]; B, idem (lateral right side).
Nota: Proportional lengths (%) of urosomites and caudal rami 12.8:58.8:7.3:6.4:10.6:11.0. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 7:22:45:11:6:9.

Espèce Triconia umerus - Planche 3 de figures morphologiquesissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.96, Fig.26].
Male (from Red Sea): A, habitus (dorsal); B, A1; C, Mxp (anterior); D, urosome (dorsal); E, idem (ventral, spermatophores fully developed); F, idem (lateral right side , spermatophores immature); G, A2 (distal endopod segment).
Nota: Proportional lengths (%) of urosomites and caudal rami 11.2:57.4:3.6:3.6:3.6:9.4:11.2. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 6.6:24.7:42.3:26.4.
Males were assigned to T. umerus on the length of the terminal accessory seta on caudal ramus, which is longer than the dorsal seta. Males of T. minuta also share this character, but can be distinguished by the length ratio of outer spines on P4 endopd-3, bydifferences in the armature of P5 exopod and by the pore pattern on the dorsal surface of the genital double-somite.
