5CF357B0640757A5BC5C11DD6BD38227.taxon	description	Description of holotype. Male subimago (Figs 1 - 3). Well preserved specimen visible in dorsoventral aspect. Head, thorax and abdomen covered by a whitish cloud of turbidity or so-called " Verlumung ", a milky emulsion surrounding the embedded carcass due to leaking gases and fluids during decomposition (Schlueter and Kuehne 1975). Body completely preserved. Left forewing partly damaged, twisted centrally, covered by streaks and overlaying cracks of amber. Rest of body also surrounded by darkened bands and cracks. The subimaginal stage is indicated by the presence of microtrichia covering the wings and by a fringe of microtrichia along posterior wing margin. Additionally, the wings are not translucent, but markedly frosted (Fig. 2). For complete measurements see Table S 1. Colouration relatively pale, dirty yellow to light brown, except of fore- and hind wings distinctly darker, coloured brown to dark brown; distal half of left forewing intensively dark brown to blackish. Due to " Verlumung ", body colouration slightly frosted. Femora relatively pale, yellow to yellowish-brown; tibiae and tarsi darker than femora, up to brown, with blackish maculation irregularly scattered. Abdominal segments unicoloured, dirty brown to greyish brown, segments VII-X fully covered by " Verlumung ". Genitalia only visible ventrally, due to streaks and cracks of amber mainly from dorsal side; natural colouration of genitalia most probably not preserved. Head. Eyes large, well developed, indistinctly separated into two portions; medially contiguous at short distance, flattened laterally; hexagonal ommatidia of upper portion of eyes well distinguishable; no preserved bands or strips on eyes laterally; ocelli poorly visible due to streaks and cracks, relatively small; antennae short, not longer than length of head; facial keel relatively large (Fig. 1 C and D). - Thorax: Prothorax mostly covered by " Verlumung ", relatively short; prosternum medially with strong bispinate projection between bases of forelegs (Fig. 1 B and D).

Numerous free short intercalaries along of tornoapical margin of forewing, and a smaller number of short marginal intercalary veins connected to longitudinal veins (Fig. 3). - Hind wings: Opaque, not translucent, nearly round, as long as 0.26 x forewing length (Fig. 1 A and B). Costal projection well developed, situated strongly proximally; widely rounded apically; numerous simple and forked cross veins between C and Sc, densely grouped in costal area; MA not forked, thus lacking MA triad; MP triad complete, MP fork situated nearly middle of vein length; CuA and CuP nearly parallel; at least three longitudinal veins and a few intercalaries in anal field. Cross venation well developed; numerous short and elongatemarginal intercalaries between RA and A 1 (Fig. 3). - Legs. Subimaginal forelegs shorter than body. Patellotibial suture vestigial, present on middle and hind legs, absent on forelegs. Tarsi five-segmented; first tarsomere longest, well separated from foretibia, but fused with tibia in middle and hind legs. Tarsi of forelegs with paired blunt pretarsal claws, in each pair one foreclaw smaller than the other; middle and hind legs with one hooked and one blunt claw (Figs 1 D, 2 B, 2 C). - Abdomen: Abdomen relatively short and massive, moderately tapered distally. Segment I shortest, fused with metathorax; segments II-V relatively short, segments VI-VII enlarged and robust; segment VI largest; tergum VI without middorsal transverse evaluation; segment IX markedly enlarged, wider than adjacent segments. Cerci completely preserved, approximately two times shorter than body; paracercus very short, segmentation not recognizable (Fig. 1 A and B).	en	Staniczek, Arnold H., Storari, Arianny P., Godunko, Roman J.

5CF357B0640757A5BC5C11DD6BD38227.taxon	description	Description of paratype. Male subimago (Figs 3 D, 4). Well preserved and almost complete specimen visible in dorsoventral aspect. Piece of amber with numerous cracks and streaks. Head, thorax and abdomen covered with thin layer of " Verlumung ". Dense layer of " Verlumung " on posterior half of abdomen, so details of genitalia poorly visible; shape of styliger basally not recognizable. Right forewing and both hind wings well preserved, complete; distal half of left forewing missing. A dense row of microtrichia along of posterior margin of wings. Wings not translucent, frosted. Legs well preserved, complete. Most part of cerci missing. For complete measurements see Table S 1.	en	Staniczek, Arnold H., Storari, Arianny P., Godunko, Roman J.

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. 7 A). - Head: Relatively small; shape of eyes not distinguishable; preserved part of facial keel relatively short. - Thorax: Prothorax not widened, relatively narrow; m esonotum with trace of elongate medioscutum; putative sharply pointed [? bispinate] projection on ventral side of prothorax, close to pointed projection trace of putative trochanter. Border between pro- and mesothorax poorly recognizable; mesothorax distinctly large; mesonotal sutures poorly preserved; shape of preserved part of MPs and putative MS similar to those in Baetisca (Fig. 5 A); lateral sclerites completely damaged; ventrally with traces of relatively elongate furcasternal projection. Metathorax short (Fig. 7 B). - Wings: 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 x of its length; RP 2 basally forked at 0.29 x 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 A 1, A 1 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 MP 2 proximally; MP and CuA without common stem; distinct short intercalary vein between MP 2 and CuA; traces of short intercalaries in MA and MP fields poorly preserved; MP 1 and MP 2 without common stem; base of CuP markedly distant from CuA base; at least five veins branching from A 1 to basitornal margin; A 2, if preserved, most probably visible in basal part of wing (Fig. 7 C, D). Ratio of hind wing / forewing length 1 / 5. Hind wing length 1 mm; rounded, almost circular appearance, with prominent costal projection near its base, rounded at tip (Fig. 7 B). - Abdomen: All abdominal terga and sterna poorly preserved; borders between segments I-IV poorly preserved, other segments with more or less preserved borders; segments IV-VI partly damaged; distal segments relatively large; segment VI the longest. Gonopods not preserved.	en	Staniczek, Arnold H., Storari, Arianny P., Godunko, Roman J.
