A. (Ammoplanus) denesi sp. n.

Male. Length of body 2.1 mm. Black including most of antenna and legs, but tarsi brown and underside of ¯agellar segments beginning with ®fth, yellowish brown; white facial mask (®gure 12) includes mandibles (except tips), labrum, sides of clypeus, spots in angles at eyes, a middle spot above black middle clypeus with tooth, and a spot anteriorly on lower half of scapus. Pterostigma bicolorous, with distal half darkened.

Head hardly broader than long, in upper half (as well as mesoscutum) moderately dull owing to dense engraved reticulation; punctures sparse, barely distinct. Frons regularly convex, without orbital foveae, only shallow depression present above toruli, interrupted by weak median ridge. Mid ocellus fully twice its diameter above upper ocular line. Eyes with inner orbits shallowly emarginate (®gure 12), converging downward (above 50 apart, below only 40); in full view eye long-oval, as 42 5 23. Toruli by nearly their diameter above lower ocular line, intertorular distance subequal to one diameter, distance from eye 1.4 times the diameter. Clypeal median tooth conical. Labrum transverse, fully twice as broad as long (high), not longer than one torular diameter, removed from torulus by a third of its diameter; its lower margin shallowly bilobed. Mandibles apparently (closed, not properly seen) without additional tooth on upper edge. Palpi not long; maxillary palpus with third segment the broadest, almost as long as two preceding ones combined. Underside of head convex, slightly dull, very ®nely striate. Occipital carina ®ne, laterally distinct. Antennal scapus widening distally; pedicel oblong; ¯agellum very slightly clavate, short pilosity almost erect, placoid sensilla small, not conspicuous; ®rst two ¯agellar segments subtransverse, following ones gradually quadrate to oblong, last one barely twice as long as broad, subacuminate.

Mesosoma . Pronotum not carinate. Mesoscutum convex, reticulate; parapsidal furrows hardly indicated. Scutellum with shallowly engraved reticulation and minute dispersed punctures; transverse groove close to anterior margin, narrow, not distinctly subdivided. Propodeal dorsum about two-thirds as long as broad, not convex, very shallowly and ®nely rugulose, median carina weak and irregular, con®ned to anterior half, anteriorly accompanied by some low rugulae suggesting partial areolation. Mesepimeron almost smooth. Hind tarsus long, segments 1 plus 2 combined as long as hind tibia, basitarsus not modi®ed, 0.72 the length of hind tibia.

Metasoma. Sternites 2 and 3 longer than 4 and 5, all bare and virtually without any sculpture, the ®fth with hind margin broadly and shallowly emarginate. Sternite 6 medially convex, posteriorly slightly produced and there bearing a broad elongate tuft of erect whitish setae, each seta at tip slightly curved caudad (®gure 11).

Female. Not known.
