the male of Dipara in Miscogastroidae. Similarly Thomson (1876a : 207) put 

 Tricoryphus in Spalangiina, and later (1878 : 175) referred male Dipara to another 

 group, his subtribe Diparides, in which he also included the genus Panstenon. 

 Ashmead (1904 : 334) elevated Thomson's tribe Diparides to the rank of a subfamily. 

 Tricoryphus was transferred from Spalangiinae to Lelapinae (= Diparinae) by 

 Gahan (1946 : 375). Only recently Novitzky concluded that Tricoryphus Forster 

 was the female sex of Dipara Walker, of which only males were known, and that 

 Hispanolelaps Mercet was the same as Tricoryphus ; his conclusions were published 

 by Domenichini (1953 : 80). As a result of this synonymy, Boucek (1954 : 54) 

 put the subfamily name Lelapinae in synonymy with Diparinae. In the same paper 

 (p. 52) he made Diparinae a more homogeneous group by excluding from it the genus 

 Panstenon. In his key to the Czechoslovak Pteromalidae (in Peck et al., 1964 : 28) 

 Boucek redefined Diparinae in a more satisfactory way. In the present work I have 

 employed much the same set of characters as those used by him. In doing so I have 

 taken into account a number of exotic species as well as the European. The sub- 

 family would appear to be better represented in subtropical and tropical areas, 

 particularly in Africa and South America. 



Key to European Genera 



1 Female antennae with three anelli and five funicular segments. Wings rudi- 



mentary. Male unknown .... TRIMICROPS Kieffer (p. 66) 



- Female antennae with one anellus and seven funicular segments. Wings 



rudimentary or developed. Male wings fully developed ; antennae with 

 one anellus, followed by ten flagellar segments which are not differentiated 

 into funicle and clava ; body entirely or mainly black .... 2 



2 (1) Female wings fully developed or somewhat shortened, fore wing with two 



fuscous spots, one below the marginal vein, the other in the distal part of 

 the wing ; body squat, the thorax only about 1-5 times as long as broad, 

 gaster ovate ; gastral petiole broader than long ; body mainly testaceous. 

 Males with segments of flagellum closely compacted, cylindrical, with 

 extremely short pubescence ; gastral petiole broader than long, dark ; coxae 

 black, legs otherwise mainly fuscous ; body squat 



NETOMOCERA Boucek (p. 66) 



- Female wings rudimentary ; body slender, thorax about twice as long as 



broad, gaster (Text-fig. 39) lanceolate ; gastral petiole about as long as 

 broad ; body reddish with dark markings. Males with segments of 

 flagellum suboval and separated by distinct constrictions, clothed with 

 bristly hairs whose length is greater than the breadth of the segments ; 

 gastral petiole (Text-fig. 52) about three times as long as broad, reddish ; 

 coxae, and remainder of legs mainly to entirely, reddish testaceous
