5. Compsocryptus apicalis, new species 



Figure 362 



Male: Front wing 9.5 to 11.5 mm. long; temple at midheight about 

 0.76 as long as eye, very weakly convex; punctures on mesopleurum 

 rather coarse, strong, separated usually by about 0.3 their diameter 

 but often more crowded or often sparser; basal transverse carina of 

 propodeum indistinct except behind spiracle; apical transverse carina 

 blunt, irregular, usually interrupted medially and often indistinct. 



Fulvoferruginous. Most of occiput black; upper side of pedicel 

 and of first flagellar segment usually infuscate; apical 0.4 of flagellum 

 fuscous; narrow sutural markings on thorax black; hind tibia infuscate 

 apically; tarsi yellowish fulvous; wings colored as in female; base of 

 third tergite sometimes narrowly infuscate. 



Female: Front wing 9.5 to 10.5 mm. long; temple at midheight 

 about 0.76 as long as eye, weakly convex; second flagellar segment 

 about 3.7 as long as wide; widest preapical segments of flagellum about 

 0.64 as long as wide; punctures on mesopleurmn moderately small, 

 strong, crowded and somewhat confluent with irregularly longitudinal 

 wrinkles; basal transverse carina of propodeum absent or sometimes 

 incomplete and indistinct; apical transverse carina very strong, in- 

 terrupted medially; sculpture of propodeum near apical transverse 

 carina exceptionally coarse; hind femur about 5.5 as long as deep; 

 hairs on most of second tergite sparse, their sockets separated by about 

 2.0 the length of the hairs, denser near base and sides of the tergite; 

 ovipositor sheath about 0.60 as long as front wing; ovipositor from 

 nodus to apex about 5.9 as long as it is deep at nodus. 



Fulvoferruginous. Flagellum with a broad yellowish white median 

 band which is incomplete below, black beyond the band; thorax with- 

 out or almost without black sutural markings; wings orange yellow 

 with dark brown markings, the front wing marked as in figure 362 

 (the small subapical yellow spot on front wing is of variable size and 

 sometimes absent); apex of hind tibia weakly infuscate; basal 0.18 ± 

 of third tergite with a black mark that does not reach its lateral edge 

 and is narrow or divided medially.
