Diagnosis

The structure of male terminalia of this species is unique ( Fig. 32 ). This species has not been assigned to a group because of insufficient evidence. The female is unknown.

Description

Male. TL 5.36 mm, WL 3.59 mm.

Head. Proportions HL:HW 0.99, UFW:LFW 1.67, outline prolonged trapezoid. Scapi black, short conical, about as wide as flagella; SL:SW 1.77. Flagella relatively short, slightly serrated, yellow, dark above. Mask yellow, complete. Foveae faciales short. Clypeus CL:CW 1.43, matt, scattered punctate. Frons and vertex with strong, dense punctation, pilosity short, sparse, frontal line extends from middle ocellus to yellow patches on supraclypeal area. Labrum yellow, mandibles brown.

Mesosoma compact; pilosity sparse, short, white; with white tomentose band at posterior margin of pronotum and calli. Tegulae and wing scales with yellow spots. Pronotum black, narrowly expanded forward; anterior edge sharp, dorsolateral angles edged. Mesonotum and scutellum shagreen, silky shining, punctation strong, close; metanotum coarsely reticular wrinkled; mesopleurae somewhat more coarsely punctate than mesonotum. Legs black, bright are tibiae basally and apically, foretibiae in front and basitarsi; tarsi otherwise brown; wings hyaline, venation brown. Propodeum edged, medial area marginate by a short transverse carina; terminal area sharply edged around.

Metasoma slender, spindle-shaped, black. T1 shagreen, silky shining, punctation moderate, close to dense, T2 significantly finer punctate, punctation fine, close, indistinct in shagreen, depression only transversely striate; T1 without lateral fringes. Terminalia ( Fig. 32 ): genital capsule short, compact, gonoforcipes apically expanded inside downwards; S7 proximal lobi with a single long bristle on each lobus near distal lobi.

Derivatio nominis

I name this new species in honour of Bernhard Klausnitzer (Dresden) on the occasion of his 75th birthday in 2014. The meritorious German entomologist supported my work in many ways.
