Remarks - S. media sp. n. is a close relative of S. minuta. However, it is much bigger and details of male genitalia serve as a safe basis for their identification. It is worth stressing an additional character for the genus: an inclinate pair of inner occipital setae present slightly mesally to the inner vertical setae. Heleomyzids are a - not unique - group of flies, whose pheromones are perceptible by human sensation. The smell of Orbellia ROBINEAU-DESVOIDY, 1830 adults is similar to that of the human feces, the pheromones of Suillia ROBINEAU-DESVOIDY, 1830 spp. smell not bad but very characteristic and that is ejected in so high quantities that one can perceive it easily near mountain streams, where Suillia specimens are abundant in the autumn period. The picture of the pheromone gland of the new species (Fig. 10) is published here in order to call attention to the importance of their study. I presume that the pheromone complex of a given species must contain not only species-specific components. If one finds several specimens of a heleomyzid species on a tree trunk, it is possible that specimens of another not related species occur there next day (Scoliocentra sp. vs Tephrochlamys sp. at Szelcepuszta, Aggtelek). Muscidae Lispe apicalis MlK, 1869 - 2 males: KNP, Fülöpszállás, Kelemen-szék, iszapon [on mud] pantraps, 2006. aug. 15., leg. PAPP L. & FÖLDVÁRI M. It is a very interesting record, since the species was not collected in the 20

tri century in Hungary. THALHAMMER caught it somewhere near Kalocsa at the end of the 19* century, and those specimens served as basis for recording it from the modern Hungary (MIHÁLYI 1975). However, despite strong efforts for capturing it again, MIHÁLYI did not manage to collect it. Fortunately THALHAMMER's specimens are still in the HNHM: our all Lispe material as "anthomyiids" (that time also Lispe spp. were included) was on loan during the time of the fire in the Baross Street in November 1956. * Acknowledgements - I am grateful to Dr MATTHIAS JASCHHOF (Swedish Museum of Natural History, Section for Entomology, Stockholm) for the identification of L. parvistyla and for his advice.
