Etymology: Named after the late Professor Yuri A. Popov, a specialist of fossil taxa and the one of the authors of the genus Metoisops; a noun in the genitive case.
Holotype: CNU CNUHHMF005, female in a 25×39 × 15 mm in piece of Baltic amber, with the curatorial museum code.
Type locality: Unknown locality on Baltic Sea Coast, Poland or Russia.
Type horizon: Baltic amber, mid-Eocene (ca. 44.1±1.1 Ma according to Wappler 2005).
Material.— Holotype only.
Diagnosis.—Differs from other congeners by the following combination of characters: body size large, more than 3 mm, deeply punctate, covered with densely golden pubescence (Fig. 3A 1); head extremely transverse, wider than 3× longitudinal length; vertex wide, as wide as 1/4 head; compound eye as wide as 1.6× vertex; second antennal segment as thick as first segment; third segment longer than fourth segment; fourth antennal segment not divided; second labial segment shortest; third labial segment longest (Fig. 3A 1 –A 4); posterior pronotal width shorter than 2 times longitudinal length; mesoscutum narrow (Fig. 3A 5); embolium impunctate.
Description.—Female body elongate-oval, length 3.31 mm. Mostly dark brown, partly pale brown. Head mostly pale brown; vertex and frons dark; clypeus and juga dark brown; antennae mostly dark brown; fourth antennal segment somewhat paler; labium mostly brown, apex of fourth labial segment dark brown. Thorax pronotum entirely dark brown; scutellum paler, brown; hemelytron mostly dark brown; embolial margin paler; membrane grayish, subhyaline; legs entirely pale brown. Abdomen entirely dark brown.
Body generally glossy, mostly punctate, densely covered with golden pubescence; frons and clypeus impunctate, covered with relatively short pubescence; antennae with short and dense erect setae; pronotum with large and dense punctures except for calli region, densely covered with golden pubescence; scutellum with small punctures and with somewhat short pubescence; mesoscutum impunctate; hemelytra with large punctures, covered with dense golden pubescence; embolial area impunctate; cuneus impunctate.
Head hypognathous, elongate in lateral view, anterior margin straight in dorsal view, less than pronotum height in lateral view; vertex relatively wide, 1.68 times as wide as single compound eye; compound eye slightly prominent in frontal view; ocelli large, positioned near compound eye, not close to each other; fovea antennalis positioned below compound eyes; antennae shorter than the body, four segmented, cylindrical; first segment shorter than the fourth segment, as thick as second segment; second segment longest, shorter than the third and fourth segments combined; third segment longer than 2 times fourth segment; proportion of first to fourth antennal segments 0.27: 1.01: 0.77: 0.3; frontal-clypeal part rather elongate; labium somewhat thick, exceeding hind coxae, reaching third abdominal segment. Thorax pronotum trapezoid, midline length longer than anterior width and /2 posterior width respectively, posterior margin weakly convex in middle, lateral margin straight, posterior angle slightly carinate; pronotal collar narrow; calli region weakly swollen; scutellum large, midline the same as pronotal midline length, width more than anterior pronotal width; mesoscutum narrowly developed; lateral margin of hemelytra rounded; commissure as long as scutellum length; cuneus broad, inner margin straight, cuneal fracture weakly developed; membrane with two cells (large and very small); legs moderately long; hindfemur not reaching the apex of abdomen; tarsus two segmented. Abdomen elongate, exceeding apex of cuneus. Genitalia not examined.
Measurements (in mm).—Body length 3.31; head length 0.18; head width including compound eyes 0.65; vertex width 0.16; first antennal segment 0.27; second antennal segment 1.01; third antennal segment 0.77; fourth antennal segment 0.3; first labial segment 0.56; second labial segment 0.21; third labial segment 0.6; fourth labial segment 0.33; pronotal midline length 0.52; basal pronotal maximal width (straight) 0.96; anterior scutellar width 0.80; scutellar midline length 0.60; commissure length 0.61; outer embolial margin length (straight) 1.47; maximal width across hemelytron 0.64; hindleg (femur: tibia: tarsus) 1.28: 1.44: 0.35.
