140 Z. BOUCEK 



smooth median line. Fourth tergite with median line raised and about half as long as first 

 tergite; hind margin produced medially in an angle of about 120 degrees. Fifth tergite strongly 

 convex, slightly compressed from the sides, about as long as broad dorsally, with narrow deep 

 ovipositorial furrow reaching to apex of fourth tergite. Sheaths of ovipositor normally hidden 

 in furrow, reaching about basal two-fifths or two-thirds of fifth tergite. Apex of gaster on 

 epipygium with very coarse punctures compared with crowded finer puncturation of sixth 

 tergite. 



(J. 3-4 mm. Very similar in colour and shape of body to § but for the still shorter and more 

 clavate antennae and slightly different markings and form of gaster. The latter with pale 

 yellow cross-band (sometimes subinterrupted in middle) in anterior third of expanded carapace 

 and a transverse subapical macula which sometimes is subdivided or narrowly divided in two; 

 also epipygium with small spot. Flagellum plus pedicellus combined about o-8 times as long 

 as width of head. First tergite in median line shallowly depressed, hind margin broadly 

 emarginate. Second tergite very short, ribbon-like, its hind margin still more emarginate than 

 first tergite. In lateral view highest part of gaster rather abruptly sloping from middle distance 

 between yellow markings, sloping part with shallow median groove and very slight cross- 

 depression, otherwise segmentation not indicated. Apical corners of sixth tergite rounded; 

 epipygium almost hidden in dorsal view, deeply transversely depressed. Basal and apical 

 sternites narrow, middle ones (third to fifth) slightly broader, subquadrate to slightly oblong, 

 fifth slightly depressed, sixth more deeply concave, slightly oblong, its sides converging; seventh 

 (last) oblong about 1-2 : 1, very finely punctured, at base deeply concave, also before sub- 

 truncate apex slightly concave.

The form of the body of L. namibica, with rather short ovipositor and angulate 

 hind margin of the fourth tergite in the female, reminds one much of the genus 

 Micrapion Kriechbaumer, but on other characters the species cannot be excluded 

 from Leucospis Fabricius. 



The West Palaearctic species 



The species from southern and central Europe are included in the key to the 

 African species (pp. 101-106) and those known from Turkey, the Near East, Central 

 Asia and from the eastern Palaearctic, including Japan, may be identified with 

 the key to the Asiatic and Australian species (pp. 155-162). Otherwise no special 

 key for those Mediterranean species has been prepared and the reader is referred 

 to a recently published key (Boucek, 1959), which is still valid except that L. 

 turkestanica Radoszkowski is now regarded as a synonym of L. dorsigera Fabricius. 

 The Palaearctic species are treated also by Nikolskaya (i960); the two Japanese 

 species by Habu (1961). 



These species belong to three different species-groups, viz. L. brevicauda Fabricius 

 and L. elegans Klug to the elegans-group; L. dorsigera Fabricius, L. bifasciata 

 Klug, L. obsoleta Klug and L. biguetina Jurine to the dorsigera-group; and L. gigas 

 Fabricius and L. intermedia Illiger to the gigas-gvoup.
