Procladius (Holotanypus) choreus (Meigen) sensu Pinder (1978)

Tanypus choreus Meigen, 1804: 23.

Tanypus culiciformis L. sensu Lundström (1915: 24),?not Linnaeus, 1767. Material examined. RUSSIA: Chara­Ullach Mts. at Cape Chara­Ullach, 1 ɗ, 1 Ψ, 25 vii 1902, M. I. Brussnew.

In light of the results by Kobayashi (1998), P. crassinervis and P. choreus both may be synonyms of a seasonally variable P. culiciformis, with P. c h o re u s as a short­heeled summer form. Another character used (e.g. by Roback 1971 and Pinder 1978) to distinguish P. culiciformis and P. c h o re u s the pigmentation of the abdominal tergites was not discussed by Kobayashi (1998), but is possibly temperature­dependent as well, and thus may not be informative either.
