Species Triconia rufa - Plate 1 of morphological figuresissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.81, Fig.18].
Female (from Red Sea): A, habitus (dorsal); B, idem (lateral right side); C, genital double-somite (dorsal); D, caudal ramus (dorsal, terminal setae omitted); E, P5 (dorsal); F, P6.
Nota: Proportional lengths (%) of urosomites and caudal rami 10.6:51.7:8.2:7.2:12.1:10.1. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 6.9:22.9:43.1:11.7:4.8:11.2. Dorsoposterior projection on the P2-bearing somite; the structure of the small dorsal hump seems to differ from the \"typical\" dorsal hump found in other species of the conifera-subgroup and in species of the sistergroup Oncaea s.str., such as O. clavei. In rufa, the hump is formed by a swelling of the exoskeleton in the middle of the somite, whreas it is a swelling of the posterior margin in T. conifera and in O. clevei and related species.


Species Triconia rufa - Plate 2 of morphological figuresissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.82, Fig.19].
Female: A, A1; B, A2 (posterior); C, Mxp; D, Md (showing individual elements); E; Mx1; F, Mx2; G, labrum (anterior); H, idem (posterior).


Species Triconia rufa - Plate 3 of morphological figuresissued from : R. Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.84, Fig.20].
Male (from Red Sea): A, habitus (dorsal); B, A1; C, Mxp (anterior); D, urosome (dorsal); E, idem (ventral); F, idem (lateralleft side); G, A2 (distal endopod segment, anterior).
Nota: Proportional lengths (%) of urosomites and caudal rami 8.5:58.5:3.8:3.8:3.8:11.4:10.2. Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 7.2:23.9:42.2:26.7. Males were assigned to this species on the length of the terminal accessory seta on the caudal ramus, being about equal in length to the dorsal seta

The distribution of T. rufa in the eastern Mediterranean Sea as recorded by Malt et al. (1989) was questioned by Böttger-Schnack (1997) and Böttger-Schnack & Schnack (2009). They  found a number of as yet undescribed, new species close to T. rufa and T. hawii  in the Mediterranean Sea, which need to by examined further and described in detail. By then, the recent record of T. rufa in the Gulf of Naples (Di Capua & Boxshall 2008) might have to be revised as well.
