N: 3
Lg.:
(679) F: 1,41-1,31; M: 1,13-1,08; (681) F: 1,37-1,26; M: 1,06-0,98; {F: 1,26-1,41; M: 0,98-1,13}
Rem.: epi-mesopelagic.
Sampling depth (Antarct., sub-Antarct.) : 0-500-1000 m.
Heron & Frost (2000, p.1017) do not agree that the generic definition of Triconia by Böttger-Schnack (1999) is sufficient to justify inclusion of all of the divergent species she assigned to the new genus.
