( Figs 3 , 4 , 11C )

Quartinia mongolica : Fateryga & Buyanjargal 2022: 11 , ♀ ♂, part.

Diagnosis. The species is closely related to Quartinia mongolica ( Morawitz, 1889) but differs from it by a distinctly larger size (total body length 4.5–5.5 mm versus 3.5– 4 mm in Q. mongolica ), predominately black coloration with a pale yellow pattern usually outlined by ferruginous and a reddish to reddish-brown apical tergum in both sexes ( Figs 3A, B, D , 4A, C, D ) (versus a black coloration with an extensive orange-yellow pattern and a reddish-yellow apical tergum in Q. mongolica , Fig. 13B ), and a less broad cupula in relation to the remaining parts of the male genitalia ( Fig. 11C ) (versus a broader cupula in Q. mongolica , Fig. 11D ).

Description. Female. Body length (from head to apical margin of tergum II) 4–4.5 mm (total body length about 5–5.5 mm); forewing length 3.5 mm. Head in frontal view about 1.3× as wide as long (from top of median ocellus to apical margin of clypeus). Clypeus with concave disc, about 1.25× as wide as long; its apical emargination rather deep, about 0.4× as deep as wide, taking about 0.5 of clypeal width, apical teeth broadly rounded and narrowly lamellate. Distance between lateral ocellus and occiput about 1.15× as distance between lateral ocelli and about 1.3× as distance between lateral ocellus and compound eye. Antenna with articles 8–12 forming club about 2.6× as long as wide in dorsal view. Width of gena in front of ocular sinus about 0.75× as width of compound eye at ocular sinus. Occipital carina complete, forming indistinct obtuse angle just below ocular sinus. Pronotum with anterior side nearly vertical, roundly angled to dorsal surface. Antero-lateral sides of pronotum broadly rounded in dorsal view; in lateral view, pronotal carina weakly lamellate, distinctly separating antero-ventral area of pronotum from its dorsal area at antero-lateral sides. Scutellum separated from mesoscutum by transverse suture, slightly convex, broadly rounded posteriorly. Tegula with broadly rounded outer margin produced posterior to blunt medio-posterior angle. Epipleural and episternal sulci weak. Ventral mesepisternum evenly rounded ventrally. Epicnemial carina indistinct. Dorsal carina of propodeum complete, produced dorso-laterally as nearly right rounded angle; lateral carina of propodeum complete, ventro-laterally also produced as nearly right rounded angle. Terga I–V and sterna II–V with transculent apical lamella.

Disc of clypeus rather shining, sparsely punctate, interspaces much exceeding puncture diameter on median line, weakly reticulately microsculptured; punctation becoming denser laterally, where interspaces less than puncture diameter. Punctures on frons as coarse as those on disc of clypeus, interspaces usually exceeding puncture diameter, rather shining but with distinct reticulate microsculpture. Sculpture becoming denser and duller on vertex behind ocelli where interspaces much narrower than puncture diameter. Gena shining, with fine and very sparse punctures and indistinct microsculpture. Pronotum punctate coarser than clypeus and frons, interspaces usually exceeding puncture diameter, rather shining but with distinct reticulate microsculpture. Punctures on scutum and scutellum as coarse as those on pronotum but interspaces much larger, several times exceeding puncture diameter and more shining, with weak microsculpture. Tegula with weak reticulate microsculpture and few fine punctures on posterior half. Dorsal and ventral mesepisterna and mesepimeron sculptured denser and slightly coarser than pronotum. Posterior surface of metanotum shining, with smoothened micropunctures. Metapleuron and lateral surface of propodeum rather dull, with shagreened reticulate sculpture. Dorso-lateral surface of propodeum with shallow cell-like sculpture. Posterior surface of propodeum shining, with shallow dense punctures, interspaces less than puncture diameter. Metasomal terga dull, with reticulate microsculpture and shallow dense punctures; both punctures and interspaces increasing in size towards apical margins of terga; largest punctures on terga much finer than those on scutum and scutellum. Metasomal sterna I–V regularly punctuate with fine shallow punctures, interspaces exceeding puncture diameter, rather shining, with weak reticulate microsculpture. Punctures on sternum VI denser than those on preceding sterna, interspaces not exceeding puncture diameter, duller.

Mandible and labrum covered with thin erect pale setae slightly exceeding in length diameter of median ocellus. Clypeus, frons, vertex, and pronotum with short pale setae several times less in length than diameter of median ocellus. Compound eye bare. Scutum, scutellum, and mesopleuron without visible setae. Propodeum, metasoma, and legs from coxae to femora mostly with short appressed setae. Tibia and tarsus of foreleg with short erect stiff setae approximately as long as diameter of median ocellus, those setae on mid and hind legs much shorter.

Basal color black. Following parts pale yellow outlined by ferruginous: elongate medial spot on clypeus (reduced in one specimen), spot on upper part of gena (reduced in two specimens), antenna except brown dorsal sides of scape and club, anterior band on pronotum, tegula, C-shaped spot on posterior half of scutellum, thin apical band on scutellum, metanonum, apical bands on terga I–V, legs from tops of femora. Distal half of mandible, labrum, metasomal tergum VI, and sternum VI reddish to reddish-brown. Wings transparent; veins and pretostigma pale brown.

Male. Body length (from head to apical margin of tergum II) 3.5 mm (total body length about 4.5 mm); forewing length 3 mm. Structure resembles that in female except the following: head in frontal view about 1.35× as wide as long, clypeus about 1.2× as wide as long; its apical emargination shallow, about 0.2× as deep as wide, apical teeth blunt but not broadly rounded. Distance between lateral ocellus and occiput about as distance between lateral ocelli and about 1.65× as distance between lateral ocellus and compound eye. Width of gena in front of ocular sinus about 0.5× as width of compound eye at ocular sinus. Tergum VII apically with two rounded lobes and deep emargination between them. Sternum VII+VIII rather flat, apically tridentate, central tooth broader and longer than lateral ones. Genitalia as in Fig. 11C . Foretibia not modified.

Sculpture and setation as in female except that clypeus more finely and sparsely punctate, interspaces reaching several puncture diameters on whole disc. Sternum VI sculptured as previous sterna; sternum VII+VIII sculptured as sternum VI in female. Coloration resembles that in female but clypeus almost completely whitish-yellow and spot on gena absent. Metasomal tergum VI with apical band as on preceding terga; sternum VI as preceding sterna; tergum VII and sternum VII+VIII reddish.
