218 Z. BOUCEK 



rugae; occipital carina low but distinct; ocellar triangle about 2-3 : 1; POL 3-2 times OOL; 

 median ocellus half diameter from high scrobal carina. Head in facial view 1-09 times as 

 broad as high. Supraclypeal area strongly convex, medially with smooth raised strip, 

 interantennal area with fine keel. Relative measurements: breadth of head 56, frontovertex 

 29, scrobes 19, lower face 22-5, its height 25, eye 36 : 24, malar space 10, mouth 18, scapus 13. 

 Flagellum plus pedicellus 1 -28 times as long as breadth of head, moderately clavate. Pedicellus 

 dorsally slightly oblong (i-i : 1); first flagellar segment about 1-4 times as long as pedicellus, 

 itself 1-33 : 1, dorsally in basal third abruptly narrowed, hardly shorter but slightly narrower 

 than the second. 



Thorax dull, reticulate puncturation not very coarse but very dense; very narrow interspaces 

 microscopically striate, as in M. dolichum; pubescence very short, dark. Pronotum with hind 

 margin barely emarginate but carinate in middle, premarginal carina weak; sides with short 

 carina behind middle; lateral panel rather regularly depressed. Mesoscutum slightly flattened 

 postero-medially, in certain lights notaular furrow traceable anteriorly, indicated by deeper 

 punctures. Scutellum 1-3 times as broad as long, slightly convex, preapical punctured line 

 shallowly impressed. Dorsellum crescentic, margin finely carinate; dorsum swollen and fairly 

 shiny, finely sculptured: shallow longitudinal rugulae intermixed with small punctures. Pro- 

 podeum medially three times as long as dorsellum, 0-7 times as long as scutellum, 1-7 times as 

 long as distance between median carina and plica posteriorly; median carina straight, regular. 

 Upper mesopleurum dull, dense punctures about twice smaller than on metapleurum. Hind 

 coxa in triangle below base of lateral edge extremely finely and densely punctured, with dense 

 silvery pubescence; depression with extensive dense puncturation, impunctate area transversely 

 striate, dorsal tooth distinct; dorsal edge densely punctured, regularly swollen, barely narrowing 

 caudad. Hind femur densely finely punctured, interspaces shagreened. Stigmal vein of fore 

 wing curved, terminal processus hardly indicated, uncus long; pubescence black and dense even 

 on basal cell. 



Gaster very slender, as in M. dolichum. First tergite fully twice as long as broad, slightly 

 expanding at three-quarters of length; densely punctured but for three subtriangular areas at 

 base (these microscopically reticulate) and for smooth median line narrowing into a keel 

 anteriorly. In holotype gaster elbowed behind first tergite (Text-fig. 252) suggesting its 

 position at oviposition and exposing both parts of second tergite. Punctured (i.e. normally 

 exposed) hind part of third tergite about 0-3 as long as its width, slightly transversely depressed 

 except for raised median line; hind margin very obtusely angulate (about 140 degrees). Fourth 

 tergite not transversely depressed, slightly raised in median line and with fine groove on top, 

 about o-6 as long as broad; hind margin arcuately angulate, the very apex at about 50 degrees 

 but angle broadening subapically. Fifth tergite broadest in anterior third, highest in anterior 

 sixth, otherwise regularly convex, densely punctured, narrow interspaces with faint but 

 conspicuous (at 50 X ) microscopic reticulation ; ovipositorial furrow narrowly reaching apex 

 of preceding tergite, slightly edged to slightly carinate anteriorly. For lateral view see 

 Text-fig. 252.

In the shape of the body this species is very similar to the preceding Micrapion 

 dolichum sp. n. and, together with the following species, forms a little group with 

 relatively long ovipositor and only moderately clavate gaster.
