The purpose of this application, under Articles 23.9.3 and 81.2.3 of the Code, is to conserve the widespread usage of the name Halectinosoma Vervoort, 1962 for a common genus of primarily marine harpacticoid copepods in the family ectinosomatidae. The name Halectinosoma is threatened by the senior subjective synonym Pararenosetella Lang, 1944 (type species Ectinosoma erythrops Scott & Scott, 1896). In the interest of stability and universality it is proposed to set aside all previous type fixations for Halectinosoma Vervoort, 1962 and designate Ectinosoma chrystalii Scott, 1894 as the type species. The originally designated type species is Ectinosoma sarsii Boeck, 1873, but this species is now considered as being incertae sedis in the family ectinosomatidae and its generic affinity is uncertain. It is also proposed that Halectinosoma Vervoort, 1962 be given precedence over Pararenosetella Lang, 1944 whenever the two names are considered to be synonyms.
