Stigmapsylla klimaszewskii Shcherbakov, sp.n.

Fig. 13 .

MATERIAL. Holotype forewing (incomplete at RP apex) and underlying hind wing PIN 5340 /1378±; Khasurty , 10 km S of Tsakir, Zakamensk district, SW Buryatia, Russia; Lower Cretaceous.

DESCRIPTION. Forewing 2.8 mm long, rather elongate (2.3:1), widened up to before nodus, narrowly rounded apically. Nodal line absent. Costal margin arched, more deeply in the middle; costal space moderately wide (4.8:1). Pterostigma distinct, subtriangular, with sharp, anteriorly recurrent basal boundary. R+M+CuA dividing before 1/5, R stem before 1/4, and M+CuA about 1/3 wing length. R fork basally narrow, with nearly straight RA and proximal RP. M+CuA stem thrice longer than R stem and slightly longer than R+M+CuA. M stem equal to M2 and x1.6 as long as CuA stem, M fork wide (2.4:1). CuA1 x1.6 as long as CuA stem and x4 as CuA2. Clavus rather wide, with arched posterior margin; Pcu+1A distally not running along the margin and joining it near clavus apex. Veins and pterostigma dark, membrane pale. Hind wing delicate, much shorter and narrower than forewing, R–RA and CuA are visible.

ETYMOLOGY. To the memory of a Polish expert in psyllids, Sędzimir Maciej Klimaszewski (1937–2001).
