Type material. Holotype. Female. Carsten Gröhn collection, Glinde, No. CGCG11894 , deposited in LIB— Leibniz-Institut zur Analyse des Biodiversitätswandels (former Centrum für Naturkunde—CeNak), Universität Hamburg, with number GPIH 5077 View Materials . Piece of cloudy amber, cut and polished to irregular polygonal shape. Forewings partly spread, hind wings distorted, a break running through the specimen, and a few bubbles distorting the image.

Diagnosis. Forewing with terminals of veins R 1, Rs, M and CuA not reaching margin of forewing. Stem R about as long as common stem R+M+CuA (measured from base); R 1 forked at basal half of forewing; Rs more than 2.5 times as long as common stem ScP+R; M visible in apical half of forewing; CuA straight, directed to posteroapical angle, claval vein CuP distinct, anal vein visible.

Description. For measurements see Table 1.

Head with compound eyes slightly narrower than pronotum. Compound eyes large, not divided, hemispherical, median ocellus well visible from dorsal side. Antennae 10-segmented, scapus not visible, pedicel as long as 3 rd antennomere, antennomeres 3-8 flask-shaped, widened apicad, apical borders of antennomeres 2-9 oblique; antennomere 10 narrow, not widened, tapering in apical section, with single terminal seta.

Thorax deformed, plates partly separated and shifted. Pronotum V-shaped, narrower than mesoscutum, anterior margin distinctly protruded anteriorly in median portion, with posterior margin arcuate, elevated, without distinct incision. Mesopraescutum subtriangular, longer than wide, about ⅓ as wide as pronotum, anterior margin rounded, posterior margin delicately protruded into mesoscutum, lateral angles acute. Mesoscutum the widest, in shape of two overlapping diamonds, narrowest in the middle, anterior angles rounded, anterior margin incised in the middle, anterolateral margin arcuate, lateral angles distinctly elongate, expanded, posterolateral margin almost straight, median portion with shallowly arcuate incision; lateral portions of disc convex. Mesoscutellum longer than wide, anterior margin arcuate, posterior portion acutely elongated, disc convex. Metathorax not clearly visible.

Forewing distinctly widening apicad, widest at ⅔ of its length, 2.0× longer than wide. Costal margin straight at base, then merely arcuate, apical margin strongly arcuate, posterior margin almost straight, basiclaval margin widely arcuate; margins of forewing covered with tubercles. Basal section of ScP slightly shifted from stem R+M+CuA, R 1 separated basad than half of forewing length, straight, not reaching margin; Stem R about as long as common stem R+M+CuA (measured from base); branch Rs curved and upturned, about 2.75 as long as branch R 1, not reaching margin; R 1 forked at basal half of forewing; Rs more than 2.5 times as long as common stem ScP+R; M visible in apical half of forewing, faintly concave; branch CuA leaving common stem at ⅕ of forewing length, long and straight, not reaching margin; claval vein CuP distinct, claval apex exceeding ⅔ of forewing length; anal vein visible. Veins R 1, Rs, M and CuA not reaching margin of forewing.

Hind wings weakly visible, the left one superimposed by forewing; right one bent, both hind wings partly curled.

Abdomen wax plates not visible; female terminalia weakly visible.

Etymology. The specific epithet is given after the eminent specialist of Psylloidea and our friend, Dr. Daniel Burckhardt, to celebrate his birthday.

Age and occurrence. Earliest Cenomanian (Upper Cretaceous ; ‘mid-Cretaceous’ auct.); amber of Kachin, Myanmar.
