Leucospis sedlaceki sp. n. 



(Text-figs 237, 238) 



9- 8-2 mm. Black with steel-bluish tint most apparent on thorax; pale lemon-yellow are: 

 scapus beneath, broad arcuate band on pronotum (narrowed in middle), broad band indented 

 in middle on scutellum posteriorly, upper mesepisternum, metapleurum, broad narrowly 

 interrupted band on middle of first tergite, narrower band interrupted by ovipositorial furrow 

 just behind middle of fifth tergite, narrow band dissolved in two submedian and two post- 

 spiracular spots on sixth tergite, narrow line along ovipositor on apex of gaster (epipygium), 

 apex of hind coxa ventrally and a streak along ventral (toothed) edge of hind femur. Wings 

 nearly uniformly dark brown. 



Head distinctly broader than pronotum (70 : 65), dorsally 2-3 times as broad as long, with 

 distinct though short temples. Occipital carina not high but reaching to behind eyes, nearly 

 touching lateral ocelli, sublaterally not very sharp ; vertex even laterad of paired ocelli rugulose- 

 punctured, ocellar triangle weakly convex, about 2-6 : 1; POL : OOL as 11-5 : 9-0; ocelli 

 of normal size, median one separated from curved scrobal carina by narrow groove; frontal 

 protuberances moderate. Head in facial view 1 -39 times as broad as high ; face densely but 

 not very finely punctured, only on lower face punctures rugulose, with dense whitish pubescence 

 of medium length; inner orbits distinctly emarginate. Relative measurements: height of 

 head 50, width of frontovertex 37, scrobes 33, lower face 36-5, its height 25, eye 39 : 26, malar 

 space 10-5, width of mouth 27, scape 17-5; flagellum plus pedicellus 83, i.e. nearly 1-2 times 

 as long as breadth of head. Interantennal area distinctly raised with sharp median keel 

 above. Lower margin of clypeus hardly produced, its lobes very low, median tooth obtuse, 

 low. Malar space in front of indicated suture with slightly depressed strip of fine granulate- 

 reticulate sculpture slightly expanding at eye. Pedicel dorsally distinctly elongate (1-3 : 1), 

 about as long as first flagellar segment. Flagellum slightly clavate, segments mainly oblong, 

 seventh and eighth subquadrate, second distinctly longer than first (nearly 1-5 : 1); clava 

 about 1-7 times as long as broad. 



Thorax with extremely short dark pubescence and rather fine and very shallow puncturation ; 

 interspaces on mesoscutum and scutellum up to nearly as broad as punctures, extremely finely 

 granulate-reticulate. Pronotum rather short and strongly transversely convex, in middle 

 with faint transverse depressed belt more apparent in slightly concave sides; hind margin 

 slightly emarginate and very finely carinate; premarginal carina indicated by narrow very 

 slightly raised strip of minute reticulation, hind margin of strip more abrupt but not distinctly 

 carinate ; sides of pronotum distinctly converging ; lateral panel low, distinctly depressed below 

 ridged upper margin. Mesoscutum: notaular grooves anteriorly indicated by arcuate lines 

 between deeper punctures; vestiges of parapsidal furrows shorter than their distance from 

 posterior corner which is about 125 degrees. Scutellum 1-44 times as broad as long, fairly 

 convex, punctured impressed line at hind margin very narrow. Dorsellum semicircular, flat, 

 bare, coarsely alveolate along raised-carinate margin. Propodeum medially distinctly longer 

 than dorsellum, very convex, punctured; pubescence black, thin, short; median carina weak, 

 about as long as its distance posteriorly from the conspicuous plica. Upper mesopleurum 

 more densely punctured than metapleurum, microscopic reticulation distinct on metapleurum 

 but indistinct on mesepimerum. Legs slender; fore femur and tibia dorsally terete. Hind
