A Revision of the Scenopinidae (Diptera) of the World 



Introduction 



Since Krober's (1937) last revision of the Scenopinidae, no attempt 

 has been made to classify this family on a worldwide scale. More 

 recent papers by Paramonov (1955) on Australian Scenopinidae and 

 D. E. Hardy (1944a) on North American species have treated with local 

 faunas and have made valuable contributions to our knowledge. 

 Krober (1913, 1914a, and 1925) included many illustrations of the 

 head and mngs of previously described and new species. D. E. Hardj^ 

 (1944a, 1944b, and 1960) is the first author to illustrate extensively 

 the external genital structures as well. No attempt has been made, up 

 to the present, to make detailed comparative studies of both external 

 and internal structures of the male and female genitalia; only a single 

 illustration of the internal structure of the male was found, that of 

 Scenopinus fenestralis by Engel (1932). 



The use of the genital structures has led to extensive revision of the 

 famdy, the erection of a number of new genera, and the synonymizing 

 of several which had no apparent justification. The use of the internal 

 genital structure has been invaluable in separating species whose 

 visible external features are so close that they could not otherwise 

 be separated. 



The type and allotype of every available described species has been 

 figured and any discrepancies in the original descriptions have been 

 noted. Where types have been lost, topotypes agreeing with published 

 figures have been illustrated. 



In the present classification, the family includes 16 genera, four 

 subgenera, and 214 species. The genus Lagariniis Enderlein (1913), 

 included by Krober (1914a), was placed in synonymy with the genus 

 Chiromyza in the family Stratiomyidae by G. H. Hardy (1921) and Bezzi 

 (1922). Of the 13 genera listed by Krober (1937) only six remain. Two 

 new genera were erected by D. E. Hardy (1944a) and two by Paramonov 

 (1955), while an additional five genera and four subgenera have been 

 erected by me. The following genera have been removed from Krober's 

 list: Cerocatus Rondani (1848) belongs in the There vidae as indicated 

 by Rondani's plates, and thus will not be treated in this paper. 

 Omphrale Meigen (1800) has recently been suppressed by the Inter-
