Dyscritobaeus maputanus sp. n.

(Figs 1–3)

Material examined: Holotype female: “ MOZAMBIQUE, Maputo, May 1989 leg. Mrs Angela ”. The left antenna, wings and legs are slide mounted in Faure’s medium. Holotype is deposited in the Insect Collection of Portici Università Federico II-Napoli, Italy .

Diagnosis: Dyscritobaeus maputans shares the reduced postmarginal vein with D. bicolor , differing in the unsculptured praeoccipital carina and the longer distance between the hyperoccipital carina and the lateral ocellus.

Female body length: 1.3 mm.

Colour: Head and mandible apically dark red; meso- and metasoma, A2–A12, coxae and tegula orange; mandibles proximally, scape and legs excluding coxae egg-yellow; wings white and semi-transparent.

Head: HW:HL:HH: IOS:MS = 24:5:18:18:3; EH:EW = 10:7; foramen magnum closely located to posterior margin of praeoccipital area; praeoccipital area unsculptured; distance between lateral ocellus and hyperoccipital carina equal with diameter of ocellus; central keel absent; antennal scrobe short and smooth; frons sculpture except antennal scrobe composed of regular shaped polygons with punctate margins; interantennal process strongly protruding; cheeks with radiating sulci; gena very weakly sculptured; mandible bidentate; interommatidial setae short.

Mesosoma: MW: ML = 25:22; mesoscutum sculpture composed of regular shaped polygons with punctate margins; mesoscutellum sculpture similar to that of mesoscutum, with smaller polygons; dorsellum wide, dorsal surface almost continuous with posterior mesoscutellar rim in lateral view; dorsellar spine present, small, not surpassing anterior margin of propodeal metapectal complex in dorsal view; notaulus and median mesoscutal line not marked by sculpture but darker in colour than surrounding mesoscutal areas; scuto-scutellar sulcus and posterior scutellar sulcus not foveolate; posterior ¼ of mesoscutum convex; forewing distinctly surpasses posteriormost point of metasoma; the forewing has a reduced postmarginal vein.

Metasoma: MTW:MTL = 27:31; lT1:lT2:lT3:lT4 = 4.5:9.0:7.0:5.0; MTL slightly longer than head+mesosoma (33:32); basal margin of T 1 not raised, with ten shallow foveae; weak sulci arising from medial foveae extending to posterior margin of tergite; interfaces between sulci punctuate; paired longitudinal submedian carina on T 1 present, separating densely sculptured external and smooth internal areas; weak carina at each side with the section bordering the median part smooth while that external to the carina appears densely striated with extremely tiny elements. The apical surface of narrow, smooth area extending along posterior margin of T 1 between submedial carinae; length of narrow area equals length of narrow areas extending along anterior and posterior margins of T 2; specillum absent; basal foveae on T 2 absent; weak longitudinal sulci arising from along posterior margin of anterior narrow smooth area reaching ¼ of tergite; T 2 and T 3 sculpture composed of regular polygons similar to that of mesoscutellum but smaller in size; remaining tergites with similar but sparser sculpture; in addition, the basal ¼ of the surface of T 2 is crossed by weak costae; dorsellum wide, hardly emerging from the posterior rim of the scutellum, punctate above and terminating at the meson in a weak short spine which little surpasses the median parts of the propodeal halves. Interantennal process strongly protruding; central keel absent; scrobe very short and smooth; remaining sculpture of the frons until the vertex like that described for the mesoscutum, while that on the temples and genae is ill-defined being almost unsculptured; praeoccipital area unsculptured. Vestiture of the body consists of short greyish elements.

Male: Unknown.

Biology: Unknown.

Etymology: The species is named after the city of Maputo, Mozambique.
