Leucospis speifera Walker 

 (Text-figs 93-95) 



Leucospis speifera Walker, i860 : 21-22, §. LECTOTYPE § (here designated). Brazil: 

 Amazonas, (Ega =) Tefe (BMNH) [examined]. 



The only original specimen known of speifera is designated as lectotype. 



The species is close to L. imitans sp. n., but has much more brightly coloured 

 body with sparser puncturation. In the female the first tergite is about 1-5 times 

 as long as broad, dorsally with median ridge separating the two broad furrows, 

 these slightly diverging, ridge and furrows mesad smooth and shining, but the 

 tergite densely punctured laterad of the furrows posteriorly and with thick hairs 

 converging towards the apex of the median ridge; hind margin of the first tergite 

 rather broadly smooth. The male was previously unknown. 



O*. 9-5 mm. Body mainly metallic purplish black, with following parts bright cupreous: 

 face except below eyes, temples, axillae, sides of metanotum and of propodeum, upper 

 mesopleurum, hind coxa except dorsally, first tergite, hind margins of tergites 3 to 5 and their 

 sides (here less bright); pale yellow, as in §: scape, lateral and posterior margins of pronotum, 

 hind margin of mesoscutum, fore and mid knees, tibiae and tarsi, hind coxa dorsally and 

 ventro-apically, hind femur except median streak, hind tibia dorsally and apically, hind tarsus. 

 Fore wing brownish, fairly dark along anterior margin. 



Head dorsally fully 2-3 times as broad as long, in facial view 1-13 times as broad as high; 

 frontal protuberances moderate but rectangular in lateral view; ocelli of medium size. Relative 

 measurements: head width 65, frontovertex 38, lower face 33, its height 27, eye 39-0 : 25.5, 

 malar space 11, flagellum plus pedicellus 1-16 times as long as breadth of head, hardly subclavate, 

 middle segments subquadrate. 



Thorax rather coarsely regularly punctured, interspaces distinct, generally one-quarter to 

 one-third the width of punctures, with microscopic cross-reticulation which is nearly obliterated 

 on scutellar disc. Scutellum not depressed at hind margin. Dorsellum bare, narrowly 

 crescentic, with raised marginal carina and more raised median cross-ridge separating broad 

 alveolae in two rows. Propodeum medially fully twice as long as dorsellum, raised, with 

 strong median carina which is elevated in middle into obtuse tooth; puncturation coarse, hairs 

 not dense, directed obliquely sideways from median carina; plicae high. Upper mesopleurum 

 posteriorly (epimerum) with nearly smooth interspaces, anteriorly interspaces beset with minute 

 punctures. Fore femur dorsally hardly edged, tibia rounded. Hind coxa behind basal carina 

 laterally narrowly depressed, at base of lateral edge finely punctured and hairy, beneath only 

 very sparsely punctured and smooth, shiny; lower half of depression punctured, upper (yellow) 

 half smooth, including dorsal edge which forms posteriorly a partly translucent tooth-like lobe. 

 Otherwise as in $ (for legs see Text-figs 93, 94). 



Gaster (Text-fig. 95) hardly longer than head plus thorax, about 2-5 times as long as broad, 

 dorsally subfusiform, all tergites distinct, though third to sixth fused, but indicated by colour 

 and much finer puncturation at hind margins. First tergite about 1-2 times as broad as long, 

 0-73 the breadth of gaster, with extremely short immargined basal fovea with two submedian 

 reticulate swellings on its bottom; more coarsely punctured than following tergites; of these 

 relatively coarsely punctured are the second and sixth, remaining tergites only basally so. 

 Second tergite slightly longer than third, both together shorter than the first, this longer than
