Böttger-Schnack in Mitt. hamb. zool. Mus. Inst., 1999, 96 [p.115, Fig.37]. Female ( from Red Sea): A, habitus (dorsal); B, idem (lateral right side); C, urosome (dorsal, seta on somite near P5 and right dorsal seta missing); D, idem (lateral right side); E, A1 (arrow indicating position of missing seta); F, caudal ramus (dorsal); G, P5 (dorsal, seta on somite missing). Nota: Proportional lengths (%) of urosomites and caudal rami 9.5:54.8:8.3:6.5:9.5:11.3.
Relative lengths (%) of segments of A1 measured along posterior non-setigerous margin 6.1:24.9:42.1:11.2:4.6:11.2. Anal somite slightly shorter than caudal rami. Caudal ramus about 2.0 times as long as wide.

Distribution map of Triconia parasimilis by geographical zones
|
| | | | Loc: | | | S Red Sea: Strait of Bab al Mandab, Japan (Tosa Bay, SE Hokkaido: Oyashio region) | | | | N: | 3 | | | | Lg.: | | | (810) F: 0,75; (958) F: 0,71-0,74; M: 0,60; {F: 0,71-0,75; M: 0,60} | | | | Rem.: | epi-mesopelagic.
Close to Triconia similis with which this species can be confused.
May occur in the adjacent seas (eastern Mediterranean, Arabian Sea).
For Böttger-Schnack (1999, p.119) this species can be separated from T. similis by the length of the distal endopod segment in the A2; the form and surface ornamentation of the genital double-somite; the proportions of the postgenital segments; the length of terminal spine and the conical projection on P2 endopod; the length ratio of exopodal setae on P5; the length of the proximal seta on Mxp, and other minor differences. | | | Last update : 02/02/2016 | |
