Ptiolina obscura is a species of 'snipe flies' belonging to the family Rhagionidae. [8]
It is a Palearctic species found over most of Europe [9] [10]
Flies of this genus are tiny and black, quite unlike the normal conception of Rhagionidae. They may easily be mistaken for small Empididae and are little known probably because the species sometimes occur in considerable numbers for a very short period. Ptiolina can be confused only with Spania or Symphoromyia. Symphoromyia is distinguished by the kidney-shaped third antennal segment, or by having hairs on the metapleuron. In Ptiolina the metapleura (immediately in front of halteres) are bare. Separating Ptiolina from Spania is more difficult. The terminal style of the antenna is centrally placed in Ptiolina, Spania lacks a true style, but the ventral margin of the last antennal segment is produced into a pseudostyle.
The males are darker, more chocolate coloured than the females.
Ptiolina is a stem borer of mosses.
Johan Wilhelm Zetterstedt was a Swedish naturalist who worked mainly on Diptera and Hymenoptera.
