Holotype: "() Dessau-Anh. 4.7. leg. Zoerner 117/88" [, no. 117/88, Germany: Saxony-Anhalt, district Dessau of town Dessau-Rosslau , 4.7.1988, leg. K.H. Zoerner] ( SDEI).
Description: Complete. Body length 3.9 mm. Flagellum with 28 flagellomeres; 1 st flagellomeres ca. 3.7x longer than wide and 0.5x as long as the eye; 2 nd flagellomere ca. 3x longer than wide; preapical flagellomeres ca. 1.7x longer than wide. Temple moderately and roundly narrowed behind eye, 0.7x as long as the eye width. OOD 1.7. Transversal carina below antennae not dipped medially. Face coarsely punctate, very wide, 1.25x wider than the length of face+clypeus and 1.1x wider than the length of eye, with parallel sides. Frons and occiput with scattered punctures. Mandible with two equal teeth. MI 0.4. Genal carina reaching the hypostomal carina far from mandibular base. Mesosoma moderately depressed, 1.9x longer than high. Mesoscutum with dense and coarse punctures apico-medial, punctation less dense and coarse laterally; mesopleuron with coarse but scattered punctures; metapleuron with slightly denser punctures. Prescutellar groove slit-shaped. Areae basalis and superomedia confluent; area superomedia ca. 2.9x longer than wide; costula in its middle; area petiolaris large, hexagonal, about as long as wide. Hind femur 3.9x longer than wide, hind claws without visible teeth. Areolet pointed sessile, 2 nd recurrent vein slightly proximal to its middle; nervulus strongly postfurcal (1x its length); postnervulus intercepted behind its middle; pterostigma 2.8x longer than wide. 1 st tergite 2.25x longer than wide; postpetiolus 1.1x longer than wide, with coarse longitudinal striae, almost appearing as dorsolateral carinae; 2 nd tergite 0.75x as long as wide; thyridium large, transverse. Stylet pointed at apex, 1.6x longer than the 2 nd hind tarsomere.
Colour: Face yellow; orbits cream-yellow; head otherwise yellowish-red. Mesosoma yellow; mesoscutum with brownish spots laterally and frontal-medially; pronotum pale yellowish apically; propodeum brown, apical 1/3 yellowish. 1 st tergite black, 1 st sternite dark rufous; 2 nd tergite brown, yellow in the apical 3/10 of tibial length; 3 rd tergite yellow, with brownish band in the apical half; following tergites yellowish-brown and slightly vespoid. Legs yellow; hind tibia cream-yellow, brownish in the apical 1/10 of tibial length (0.5x of tibial width); hind tarsomeres cream-yellow with brownish tips. Pterostigma hyaline.
Remark: This taxon belongs to the genus Stictopisthus Thomson (e.g. transversal carina below antennae not dipped medially, prescutellar groove slit-shaped, nervulus of fore wing strongly postfurcal, and postpetiolus strongly striate) and is identical with the male of Stictopisthus flavescens (FONSCOLOMBE, 1852) .
Valid name: Stictopisthus flavescens (FONSCOLOMBE,
