Material studied.
Holotype female PIN 3730/411; housed in the collection of the Paleontological Institute of the Russian Academy of Sciences (PIN).
Type locality.
Baikura, Russia.
Age.
Upper Albian to lower Cenomanian, mid-Cretaceous.
Diagnosis.
Eye nearly round (vs. oval, higher than long in † Kamyristi yantardakhensis gen. et sp. nov.); axillae contiguous medially with axillar groove smooth (Fig. 9B View Figure 9 ; vs. separated medially with axillar groove crenulated in † Kamyristi yantardakhensis gen. et sp. nov.).
Description.
Body length 2.03 mm. Almost complete, except ovipositor. - Head globular, higher than long (length 0.38 mm; height 0.43); slightly pubescent on vertex and frons; frons convex, shagreened; compound eye rounded, slightly higher than long, not covering head length, postocular carina absent; vertex convex, shagreened; torulus inserted very close to ventral margin of eye; subantennal groove present; mandible with three teeth; scape short and thick (length 0.09 mm); pedicel same length; flagellomeres cylindrical, longer than wide, elongate (length ca. 0.08 mm); flagellomere 12 longest; occipital carina crenulate. - Mesosoma shorter than metasoma (length 0.69 mm; height 0.40 mm), almost fully shagreened; mesoscutum shagreened, short (length 0.20 mm; width 0.47 mm), one third of mesosoma length, divided by crenulate median mesoscutal sulcus, with sparse erect setae; axillae continuous medially, with inner axillar groove smooth; mesoscutellum as long as mesoscutum, posterior margin slightly outcurved; pronotum not visible dorsally; anterior thoracic spiracle fully surrounded by pronotal cuticle; propodeum areolate-rugose. - Fore wing hyaline (length ca. 1.50 mm) and covered with microtrichia; C, Sc+R, Rs +M, basal segments of Rs and M; M+Cu, Cu and 1m-cu spectral; Rs not closing first submarginal cell and pigmented for two thirds between r-rs and Rs+M; M pigmented to level of 2r-m and then spectral to wing tip; pterostigma broad; R1 extending beyond marginal cell; Rs pigmented, arched toward stigma, closing marginal cell. - Legs bearing many scattered erect setae; one mesotibial spur, one metatibial spur present; metafemur swollen, metatibia notched before spur; metabasitarsus three times longer than following, remainder same length. - Metasoma almost half body length (length 0.96 mm), elongate, smooth; segments subequal in length; hypopygium well-developed, concave; ovipositor incomplete, covered by sheaths only at base; cerci triangular, exserted.
