Abstract

A new genus of Chironomidae (Insecta: Diptera) is described based on a single incomplete pupa from Khutel Khara (lower part of the Tsagan Tsab Formation, Lower Cretaceous; Mongolia). The new genus displays a mosaic of Podonominae and Tanypodinae characters. The most distinctive characters of the new taxon are stout strongly darkened anal spurs, strong serration of anal lobes, and peculiar armament at the base of anal lobes, looking as an artichoke-like spinose structure, unique among Chironomidae.

Keywords:

Podonominae Tanypodinae pupae systematics SEM

ACKNOWLEDGMENTS

We are deeply indebted to Roman Rakitov (Borissiak Paleontological Institute, Russian Academy of Sciences, Moscow) for assistance in taking scanning electron images and linguistic advice and Peter Langton (Museum of Zoology, Cambridge) and to Peter Cranston (Australian National University, Canberra) for valuable discussion, and Martin Spies (Zoologische Staatssammlung, München) for loaning us pupae of extant Podonominae. The study was performed within the framework of State Research Program of the Russian Federation (no. АААА-А17-117021310121-0) and partly supported by the Russian Foundation for Basic Research, project nos. 16-04-01498 and 18-04-00988.
