To the knowledge of fauna of synanthropic flies of the Nepal Himalya.

A material of flies collected in two localities (altitude of 3900 and 4500 m) in the Barun Khola Valley (East Nepal) was studied, representing the early spring aspect of the species composition of flies. Of the total number of 2309 fly specimens 99.3% represented two species of the genus Paregle (P. aterrima, P. sp.); both are autochthonous high altitude hemisynanthrophic forms. The remainining 0.7% represent 9 species, most of which are more or less eurytopic species of palearctic or holoarctic distribution (Calliphora vicina, C. vomitoria, Meoneura flavifacies, Scatophaga stercoraria, Hydrotea hirticeps, Orthellia caesarian, Paregle danieli, Anthomyiidae g. sp. 1, g. sp. 2).
