038E7975217FA259DB72FBCBFF44991C.taxon	discussion	Remarks. Distinct from all known ipsviciids in the presence of a strigil. The new genus is more primitive than the Late Triassic genera Ipsvicia Tillyard, 1919 and Ipsviciopsis Tillyard, 1922, but is similar to these latter in the tegmen shape, deeply arched bSc, long sigmoidal dSc, lanceolate medial area, and distal R branches in an anterior pecten opposed to the posterior M + CuA pecten. The two latter genera have more elongate tegmina with a straight postclaval margin aligned with the commissural margin, horizontal costal area, concave R stem, concave longitudinal dSc reaching beyond 1 / 2 tegmen length, 2 or 3 crossveins r-m, and more numerous apical cells. The new genus is similar to the Middle Triassic (Anisian) genus Triassophyllum Papier, Nel, Grauvogel-Stamm & Gall, 1997 (Fig. 1; described in Orthoptera, later transferred to Ipsviciidae; Shcherbakov in Gorochov, 2005; Lambkin, 2020) in the moderately long dSc and presence of ocellate spots in the radial and medial areas, but in the latter genus tegmina are much larger, with rich venation, numerous crossveins and dSc originating more distally and reaching beyond 1 / 2 tegmen length. Strivicia gen. nov. is distinct from incompletely known Triassic genera Ipsvicioides Fujiyama, 1973, Doryscarta Lin, 1982, and Shaanxioscarta Lin, 1982, and the Early Jurassic genus Ipsviciella Becker-Migdisova, 1962 at least in only three anterior branches on R distal to dSc and the shape of tegmen.	en	SHCHERBAKOV, DMITRY E.

038E7975217EA259D8D0FAA1FC2C943D.taxon	description	Description. Tegmen length 4.2 – 4.4 mm, width 1.6 – 1.8 mm, elongate (length / width ratio 2.5 – 2.6: 1), as seen in the holotype and paratype from the SW Madygen area. The paratype from Dzhailoucho is stretched transversely (its surface punctures are transformed into short subtransverse wrinkles) and appears much shorter and broader, but in fact it is of nearly the same size (length 3.4 mm, width 1.8 mm, √ LW 2.5 mm) as the two former (√ LW 2.6 – 2.8 mm). Tegmen widest just before midlength, costal margin arched there, nearly straight more proximally and arched at base. Precostal carina wider proximally, deflected dorsad; hypocostal carina narrow; basicostal projection low; bSc large arch; costal fracture transverse; costal area moderately wide, its part between costal fracture and dSc sloped and occupied with oblong strigil. Basal cell short, triangular, closed with short M + CuA anastomosis. R (+ dSc) stem convex, short, oblique; dSc continuing its direction, convex, sigmoidal, moderately long (1 / 5 – 1 / 3 tegmen length, much longer than R stem), joining margin before or at (Dzhailoucho paratype) tegmen midlength. R distal to dSc longitudinal, with 3 anterior branches, bent at origin of third branch; apex of tegmen at narrow apical cell between R and M. M and CuA stems arched in opposite directions, enclosing lanceolate medial area, CuA arched close to CuP. Branches of CuA and M forming common posterior pecten with 4 terminations, CuA 1 apparently fused to posterior M branch. Crossvein r-m short, much more distal than free basal section of CuA 1 (looking like m-cu). Clavus occupying 2 / 3 tegmen length, claval veins (Pcu and 1 A) united at 2 / 3 clavus length, their common stalk entering commissural margin much before claval apex. Upper surface of tegmen covered with rasp-like punctures, coarser and denser in proximal half, especially on basicostal piece, finer and sparser in distal half. Stridulatory area on underside of tegmen 1.1 × 0.23 mm, consisting of more than 40 oblique rows of microtrichia; rows 4 times more dense at base of strigil (14 per 100 μm) than in its distal part (3.5 per 100 μm); microtrichia (except near strigil base) transformed into short ridgelets up to 15 μm long, oriented across rows, i. e. almost longitudinally. Large pale ocellate spot margined with dark in widest part of medial area, similar smaller spot more distally in radial area, and probably one more at 1 A; vein terminations margined with dark, CuA 2 with dark mark, dark specks and spots (more developed in Dzhailoucho paratype) along veins and in anterior area; ground colour pale fuscous.	en	SHCHERBAKOV, DMITRY E.
