20 mm. Haltères light brown. Abdomen black, similarly to other body parts, 0.92 mm long,

0.71 mm wide. Apart from those discussed in the diagnosis, I found no other specific characteristics on the abdomen. Holotype 3: Csévharaszt /Com. Pest/, Hungary, 12 May 1969, leg. L. PAPP, deposited in the Hungarian Natural History Museum, Budapest . The holotype is in a rather bad state of preservation. The abdomen of the animal, pinned on a minutia pin, has been detached and the right wing and hind pair of legs are missing. However, the complete abdomen and the left hind leg are glued on a label pinned below the specimen, thus a complete description could still be made. 1. oedopoda sp.n. is closely related to I.vaporariorum HALIDAY, 1836, but distinguished from it by the following characters: On the side of the fore coxa looking towards the pleurae there are some long /about 0.09 mm/

3 light, slightly sinuously curved, stronger bristles. On the ventral part of the sternopleura, evenly distributed straight bristles of a similar length but more rigid in appearance emerge. In vaporariorum,these bristles occur more sparsely and considerably less uniformly both as to distribution and strength. The legs, especially the fore and hind femora, are conspicuously thicker than in vaporariorum; the fore femur being more or less vesiculate in shape. Adjacent to the posterior margin of the sternites, two long, thick apically truncate and reclinate bristles appear /Pig. 1/; they are definitely more robust then those of the related species, especially if compared with the other bristles borne on the sternites. Some smaller differences are present also in the shape of the male genital organ.
