Length of body 7 mm; length of forewing approximately 6 mm, maximum width 3.5 mm. Imago of unknown sex. Specimen preserved in right lateral view with both forewings overlapping. Except of forewings, entire body of specimen poorly preserved, first abdominal segments not discernible, only base of cerci preserved. Right forewing is almost complete except of cubital and anal fields with venation poorly distinguishable. Traces of left forewing venation partly overlapping with right forewing venation. Costal brace and basal part of costal field almost destroyed; longitudinal venation mostly preserved and distinguishable; cross veins poorly visible, especially in anal field. Hind wings partially superimposing forewings. Hind wing mostly damaged, with poorly preserved outline and trace of costal projection; venation almost lost. Legs completely missing, except of traces of putative trochanter of right and left foreleg. Because of poor preservation of eyes and lacking gonopods, the sex of this specimen is not determinable (Fig.

: Preserved forewing of triangular shape, relatively wide, with width/length ratio approximately 0.58 [as preserved]. Longitudinal venation well recognizable; cross venation well developed, occasionally poorly visible, present in all the fields of forewing. Pterostigma with at least 15 simple and forked cross veins; only simple veins between C and Sc proximally. RP basally forked at 0.30

of its length. Longitudinal venation with complete RP, MA and MP triads; RP and MA without common stem, basally approached; posteritornous wing condition: wing tornus situated basally of CuP and A1, A1 nearly parallel and close to CuP throughout remaining length. Furcation of MA slightly asymmetrical, fork located at 0.65 of wing length; iMP slightly closer to MP2 proximally; MP and CuA without common stem; distinct short intercalary vein between MP2 and CuA; traces of short intercalaries in MA and MP fields poorly preserved; MP1 and MP2 without common stem; base of CuP markedly distant from CuA base; at least five veins branching from A1 to basitornal margin; A2, if preserved, most probably visible in basal part of wing (Fig.
