Pseudodiamesa sp.

Prodiamesa branickii Now. sensu Lundström (1915: 22).

Material examined. RUSSIA: West Taimyr, north coast, 2 ɗ without hypopygia, the labels with " branickii " added from a ballpoint pen (i. e. added later than 1945), one mislabelled as " Ablabesmyia limbata ", 20 vii (2 viii) 1901 [Lundström (1915) gave 1 viii (19 vii) 1901], A. A. Birula.

Oliver (1959) has redescribed P. b r a n i c k i i. The present specimens apparently have been re­examined and the hypopygia mounted. However, E. Makarchenko (personal communication) did not study the collection and does not know of any other Russian scientists who did. Furthermore, he knows of no records of P. branickii from arctic Siberia. In his material from the Taimyr Peninsula there are males of P. nivosa (Goetghebuer) only. However, those males are slightly untypical for P. n i v o s a and may represent a different species.
