Papp, L.: Notes on some Becker's types (Diptera, Carnidae and Risidae fam. n.)

lack of thoracic postalar and dorsocentral bristles, and presence of strong acrostichal bristle not prescutellar in position, mesopleuron with bristles, lack of posterior crossvein and basal crossvein, cerci entirely absent from abdomen of females. The new family includes very rare species. Risa longirostris BECKER, 1907 is known in two type-specimens only and a further specimen from Egypt: Wadi Gharaghid, STEYSKAL, 1968 ; Risa mongolica L. PAPP, 1977 was described on the basis of one female specimen. Thus, the study of specimens to be collected, especially that of male exemplars, will be important, partly to better characterize the family, and partly to learn more about its relations.
