A. (Ammoplanus) kazenasi sp. n.

Holotype male, here designated, deposited in BMNH London (examined).

Male. Length of body 2.3 mm. Black, rather shiny, including entire clypeus, with mandibles broadly, ¯agellum and tarsi, brown, scape dark brown. Pterostigma very pale brown, unicolorous, its margins only slightly darker.

Head stout, strongly convex (®gure 31) except for slight double depression for reception of scapes, frons and vertex (as well as scutellum) smooth with dispersed small punctures, face in lower three-®fths ®nely striolate merging with engraved reticulation (as mesoscutum). Head in facial view slightly broader than high (®gure 30), part above eyes less than half as high as length of one eye, anterior ocellus only by its diameter above upper ocular line; frons at upper ends of eyes virtually as broad as distance between lower ends of eyes, their lower ends not much produced below to toruli, orbits only slightly emarginate in middle, above without distinct orbital foveae. Each eye rather broad, 1.72 as long as broad. Lower face (®gure 30): toruli hardly one diameter apart but eye from torulus 1.8 times torular diameter; space between upper ends of toruli slightly raised and ®nely reticulate, which abruptly ends at upper clypeal margin. Clypeus rather large, smooth and shiny, its lower margin with broad submedian teeth and still more prominent median tooth which is longer than broad, slightly compressed from sides, in lateral view appearing as an aquiline nose. Mandibles without tooth on upper margin. Underside of head with sparse shallow punctures; oral fossa very broad, its sides narrowly depressed and here rugose but behind rugosity convex and shiny, further on extensively ¯at, in middle slowly receding to foramen magnum. Palpi rather short, bearing short stout setae. Occipital carina distinct on sides, interrupted dorsally. Antennal pedicel 1.4 times as long as dorsally broad; ¯agellum ®liform, almost bare, placoid sensilla small, on each segment in six or seven rows; ®rst segment slightly longer than pedicel, most others 1.6±1.7 times as long as broad, the penultimate slightly shorter, the last 2.5 times so and 1.7 times as long as penultimate one.

Mesosoma . Pronotum rather narrow, collar rounded and short, dull with ®ne transverse rugosity, along posterior margin with a carina. Mesoscutum with somewhat concentrically arranged and slightly raised reticulation which is weak and slightly obliterated in middle. Scutellum smooth, basal groove close to anterior margin, broad, subdivided by several tiny rugulae on bottom but with a stronger one in middle. Metanotum longitudinally rugose-striate. Mesopleuron rather coarsely longitudinally striate but dorsally with smooth area some distance below hind wing. Propodeum 0.7 as long as broad in middle, transversely convex, dorsally apart from short median carina with sculpture consisting of small shallow areolae merging with raised reticulation, without coarse areolae; vertical sides of propodeum with diagonal irregular striation. Hind tibia distinctly sinuate (®gure 32); basitarsus also sinuate, in widest part only twice as broad as the narrowest; latter in threequarters of length, on mesal side subconcave, with rather sparse white hairs which are slightly longer than on outer side.

Metasoma. Fourth sternite in posterior half with broad belt of semierect but rather short hairs; ®fth sternite with hind margin arcuate, apex in middle raised and bearing a small transverse brush of erect stiOE setae; following sternite in middle bare, shiny, slightly raised. Apical sternites beginning with posterior half of the fourth with moderately dense pilosity directed more or less caudad and on sternite 4 consisting of two kinds of setae: stouter, short, subdecumbent ones and more erect thin long setae arising from small tubercles; the long setae alone are present on sternites 5 and 6, there sparse on sides of 5 and in middle of 6; hind margin of sternite 5 slightly produced and in addition to pilosity in middle of apex with transverse short comb of about 6 erect stiOE setae.

Female. Not known.
