Espèce Triconia hawii - Planche 1 de figures morphologiquesissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.87, Fig.21].

Nota: Proportional lengths (%) of urosomites and caudal rami 9.2:54.3:6.2:6.2:13.6:10.5. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 7:22:44:11:4:11.


Espèce Triconia hawii - Planche 2 de figures morphologiquesissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.89, Fig.22].
Female: A, A2 (anterior); B, labrum (anterior); C, idem (posterior); D, Md (showing individual elements); E, Mx1; F, Mx2; G, P5 (dorsal); H, caudal ramus (dorsal, terminal setae omitted); I, P6; J, egg-sac.


Espèce Triconia hawii - Planche 3 de figures morphologiquesissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.90, Fig.23].
Male (from Red Sea): A, habitus (dorsal); B, A1; C, Mxp (anterior); D, urosome (dorsal, spermatophores fully developed); E, idem (ventra)) [a, b, right and left genital aperture, showing bifid tips of posterolateral corners; c, d, variation in posterolateral corners of genital apertures]; F, idem (lateral left side).
Nota: Proportional lengths (%) of urosomites and caudal rami 10.2:54.4:4.8:4.1:4.1:12.2:10.2. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 7.6:21.8:40.6:30.0.
The males were identified on the length of the terminal accessory seta on the caudal ramus, which is about equal in length to the dorsal seta; males of T. rufa also share this character, but they can br distinguished by the length ratios of spines on P4 endop-3, by the sexual dimorphism in the lateral armature of A2 (which is not found in T. hawii), by the pore pattern on the dorsal surface of the genital double-somite and by their larger size (see Table 3). The conspicuous bifid posterolateral corners on the genital flaps appear to be rather variable, and consequently cannot be used to separate the males from those of the closely related T. rufa.


Espèce Triconia hawii - Planche 4 de figures morphologiquesissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.77, Table 3].
Morphological characters separating males of Triconia minuta, T. umerus, T.rufa and T. hawii.
ODS = outer distal spine; OSDS = outer subdistal spine; endp-3 = 3th endopod segment; l = length; sex dimorph. = sexually dimorphic; GS = genital somite; P4, P5 = thoracopods 4, 5; A2 = antenna; CR = caudal rami; lat. arm = lateral armature.
