On the Validization of the Name Chironomus (Camptochironomus) pallidivittatus sensu Edwards, 1929 and Elimination of the Name Chironomus pallidivittatus Malloch, 1915

摘要

The name Chironomus pallidivittatus sensu Edwards is widely used by specialists for the European species described by Edwards, whereas the use of the name Ch. tentans var. pallidivittatus Malloch is limited. In the light of the wide use of the name Chironomus pallidivittatus sensu Edwards, particularly in fields outside taxonomy, combined with virtually no publications on the Ch. tentans variety pallidivittatus Malloch, we recommend that the original Malloch's application of the name should be suppressed in favor of that of Edwards, 1929. At the same time, synonymy of Ch. pallidivittatus s. Malloch with Ch. tentans Fabricius supposed by Townes (1945) is erroneous. Detailed cytogenetic (Kiknadze et al., 1996) and morphological (Shobanov et al., 1999)studies of North American, European, and Asian populations demonstrated the common occurrence of Ch. dilutus Shobanov, Kiknadze et Butler, 1999 in the Nearctic. This species is different from Ch. tentans but identical with Ch. tentans var. pallidivittatus Malloch, 1915 and the "Nearctic Ch. tentans" sensu Townes (1945).[The authors apparently are misled by their complete ignorance of the International Code of the Zoological Nomenclature. The statement that the species that they had described, Ch. dilutus Shobanov, Kiknadze et Butler, 1999 is identical with Ch. tentansvar. pallidivittatus Malloch, 1915 means that the name Ch. pallidivittatus Malloch, 1915 is a senior synonym and should be used as a valid name for this species instead of Ch. dilutus. The name C. pallidivittatus sensu Edwards cannot be introduced in usebecause of its homonymy with Ch. pallidivittatus Malloch.—Ed.].
