Diagnosis. Habitus slender. Head triangular in frontal view; toruli prominent, separated by deeper cleft; transverse diameter of eyes shorter than malar space; antennae very slender, filiform with preapical segments about 2.35 times as long as wide; pubescence of antennae heterogeneous, with intermittent long erect setae scattered through denser shorter setae; mesosoma slender and little narrower than head; petiole short, 2.5 times as long as wide, slightly rugose and swollen anteriorly; gaster long and fusiform with the first enlarged segment constricted posteriorly and forming neck-like tube in which all remaining gastral segments are collapsed; base of macrotergite with short medial furrow and lateral depression, space between furrows smooth; macrosternite pubescent along its entire surface.

Variability. No substantial variation apart from size (2.5- 4 mm) observed.

Bionomics. Some specimens were bred from Boletus sp (p). and Suillus sp (p). sporocarps infested by Mycetophila fungorum (de Geer, 1776) ( Diptera : Mycetophilidae ) (P. Laštovka and J. Ševčík det.). Females were also observed moving on the surface of mushroom sporocarps in the field. Flight period from July to September.

Distribution. This species is known only from France (KIEFFER 1910), Germany, Sweden ( NIXON 1957), Switzerland ( WALL 1967), Finland ( HELLÉN 1964), the Czech Republic, and Slovakia ( MACEK 1989). It is a new species for Austria.

Remark. NIXON (1957) indicated by an asterisk in his key that he examined the type of Miota compressa . However, no specimens studied by him ( England: Surrey, and Sweden: Skåne) come from the type locality ( France: Fontainebleu, coll. de Gaulle), and I therefore think he made a mistake. According to KELNER- PILLAULT’ s (1958) catalogue of Kieffer’s collection in MNHN, the type of Miota compressa is missing and probably lost. For this reason I follow NIXON’ s (1957) concept of the species.
