Taxonomy Arwidsson (1906:104) separated his subgenus Loxochona from the nominal genus because of the slightly oblique (versus straight) truncation of the anal funnel plus lack of nephridia on chaetiger 6 in 2 species, N trispinata, N. quadrispinata. Whether these are sufficiently reliable characters for the subgenus to remain valid is unclear, but De Assis et al (2007ab) use it in a table & a checklist, for example newly including Nicomache venticola Blake & Hilbig, although it is not stated why this species fits the Loxochona criteria.
Kongsrud & Rapp (2012) have commented on this and other transfers, stating "However, N. canadensis, N. maculata and N. personata are all well-documented members of the subgenus N. (Nicomache) Arwidsson, 1906, as they all possess a more or less symmetrical pygidial funnel with a centrally placed anus within the funnel, and nephridial papillae present on setiger 6 (not known for N. canadensis)."
