Abstract: The European Stenomicra cogani Irwin, 1982 (Diptera: Stenomicridae) is
redescribed including the previously undescribed female, and the variability,
biology (with first photographs of living specimens) and distribution of the
species are discussed. Stenomicra gracilior sp. nov., a closely allied and
externally very similar species (also lacking dm-cu cross-vein), is described
from southern Turkey. The morphology of the male and female terminalia is
studied in detail in both these species and in Podocera delicata (Collin, 1944)
and their structures are compared with those known in other genera of
Stenomicridae. Female internal genitalia (genital chamber and associated
structures) are described for the first time in the family Stenomicridae. Based
on the analysis of the male and female genital characters, the relationships of
the genera affiliated to Stenomicridae (Cyamops Melander, 1913, Stenocyamops
Papp, 2006, Podocera Czerny, 1929, Stenomicra Coquillett, 1900 and Planinasus
Cresson, 1914) are discussed and the validity of the genus Podocera Czerny,
1929 is corroborated. The first record of Podocera soniae (Merz &
Roháček, 2005) from Sweden is given.
