Psychoda lativentris Berdén, 1952

Material examined. ROGALAND: Klepp, Revtangen , 58.759 N 5.49871°E, 18.IX.2016, 3♀♀, leg. A. T. Mjøs (Light trap) . HEDMARK: Rendalen , Sekserbua NØ, 61.5561 N 11.1686°E, 17.VIII–2.IX.2016, 1♀, leg. Rikmyrsprosjektet (Malaise trap) . SØR-TRØNDELAG: Trondheim, Jonsvatn near Flaten , 63.3973°N, 10.5545°E, 14–28.VIII.2014, 2♂♂, leg. E. Stur, coll. NTNU (Malaise trap) .

Remarks. Although Kvifte & Andersen (2012) reported approximately equal frequencies

of males and females in P. lativentris from Finnmark, all specimens identified from Southern Norway are females. Biased sex ratios were also observed by Ježek (1977) and Quate (1955). This has been argued to indicate that P. lativentris is parthenogenetic throughout most of its distributional area, and Vaillant (1973) described P. limicola Vaillant, 1973 for North American populations of the sexual form. DNA barcoded specimens of Southern Norwegian specimens fall in the BIN BOLD:ABA0879, which also comprises specimens from Germany and Bulgaria; Northern Norwegian specimens fall in two BINs, BOLD:ABA0879 and in the very similar BOLD:ACE4614. I have collected North American specimens tentatively identified as P. lativentris and these will be sequenced in the near future.
