MACROMESINAE 



Antennae of male 13-segmented (formula 11 173), of female 12-segmented (formula 11 172). 

 All tarsi of male five-segmented ; tarsi of female heteromerous, fore and hind tarsi five-, mid 

 tarsi four-segmented ; first segment of mid tarsi in female very long. Head somewhat Eupel- 

 moid in facies ; inner orbits of eyes diverging rather strongly in their lower part ; face, between 

 malar sulcus and antennal torulus, usually with a supplementary longitudinal impressed line ; 

 both mandibles with three teeth. Notauli complete. Hind margin of propodeum almost 

 truncate (Text-fig. 65). Postspiracular sclerite absent, or imperfectly developed and marked 

 off from the mesopleuron by a superficial groove only. Fore wing (Text-fig. 66) venation 

 characteristic : basal vein indicated by an oblique pigmented spur which projects from the 

 parastigma. Other characters of the genus Macromesus are listed by Graham (1959a : 77). 



The only known representative of this group, Macromesus Walker, was originally 

 described as being possibly allied to the Eupelmidae. It was not captured again for 

 nearly a century, and the characters attributed to it by Ashmead (1904) and 

 Schmiedeknecht (1909) were not based on personal observation but drawn from 

 Walker's description ; they placed the genus in Cleonymidae and in Cleonyminae 

 respectively. In 1943 Kryger captured Macromesus and described it under the 

 name Wesenbergia ; he did not place it in any of the recognized families, although he 

 noted certain characters in which it appeared to resemble Torymidae (= Callimom- 

 idae). Macromesus amphiretus Walker, the type-species, was recognized by 

 Graham (1959a) who erected a new subfamily of Pteromalidae, Macromesinae, for 

 its reception. Later in the same year Szczepahski added some further information 

 on the structure and biology of the genus, but proposed for it a tribe Macromesini in 

 the subfamily Tridyminae. It seems to me, however, to have little in common with 

 any Tridymine, and I prefer to retain for it the subfamily Macromesinae. Boucek 

 (1961 : 57) suggested that its nearest relations appeared to be the genera Cea and 

 Spalangiopelta. There are certainly some resemblances between these two genera 

 and Macromesus, but more study is needed before it can be assumed that a real 

 affinity exists between them.
