Two new species of Mesosciophilidae (Insecta: Diptera: Nematocera) from the Yanliao biota of Inner Mongolia,China

Wang, Q., Zhao, Y.Y. & Ren, D., December 2012. Two new species of Mesosciophilidae (Insecta: Diptera: Nematocera) from the Yanliao biota of Inner Mongolia, China. Alcheringa 36, 509–514. ISSN 0311-5518.

Two new species assigned to Mesosciophila Rohdendorf and Paramesosciophilodes Zhang in the Mesosciophilidae are described and illustrated: Mesosciophila sigmoidea sp. nov. and Paramesosciophilodes aequus sp. nov. They are established based on fossil specimens with bodies and complete wings. Both were collected from the Middle Jurassic, Jiulongshan Formation at Daohugou, Inner Mongolia, China.     

The first fossil record of Nandeva Wiedenbrug,Reiss & Fittkau (Diptera: Chironomidae) in early Eocene Fushun amber from China

Gi?ka, W., Zakrzewska, M., Baranov, V., Wang, B. &; Stebner, F., May 2016. The first fossil record of Nandeva Wiedenbrug, Reiss &; Fittkau (Diptera: Chironomidae) in early Eocene Fushun amber from China. Alcheringa 40, xxx–xxx. ISSN 0311-5518

The first fossil representative of the extant chironomid genus Nandeva Wiedenbrug, Reiss &; Fittkau, 1998 Wiedenbrug, S., Reiss, F. &; Fittkau, E.J., 1998. Nandeva, gen. nov., a new genus of Chironomini (Insecta, Diptera, Chironomidae). Spixiana 21, 59–68. [Google Scholar] is described based on a specimen found in early Eocene (50–53 Ma) Fushun amber from China. The adult male of Nandeva pudens sp. nov. has the long RM vein as a continuation of M and R₄₊₅, the bare squama, the strongly reduced anal area of the wing and hypopygial characters typical of extant species of the genus. Following the systematic concept based on adult male morphology and characters examinable in fossil specimens, we present N. pudens as a possible member of the Tanytarsini, arguing that Nandeva is part of this tribe or a possible sister group to the tribe. This is the first record of Nandeva from the Palaearctic region.
