A home at last! Changania choui Tseng, 1965 belongs to Thienemanniella Kieffer, 1911 (Diptera: Chironomidae: Orthocladiinae)

Abstract

The midge Changania choui Tseng, 1965 (Insecta, Diptera, Nematocera), originally described in the family Cecidomyiidae and recently transferred to the Ceratopogonidae, is recognised as an adult female in the Chironomidae, subfamily Orthocladiinae. The type material is missing, and the published description and illustrations are limited. Although the genus name Changania Tseng, 1965 becomes a new junior synonym of Thienemanniella Kieffer, 1911, Thienemanniella choui (Tseng 1965), new combination, should be treated as a nomen dubium. A combination of two ratios calculated from wing measurements shows promise for taxonomic diagnostics in the grouping of genera around Corynoneura Winnertz.
