Age and outcrop
Early Miocene (Burdigalian), Libouš mine (Figure 1), Spořice district, Most Basin, Most Formation, Libkovice Member, about 15 – 20 m above the Crandallite Horizon C1 sensu Matys-Grygar & Mach (2013).
Description
Fore wing. Wing hyaline, 51.6 mm long; distance between base and nodus 26.6 mm; between nodus and apex 25.3 mm, nodus nearly midway between base and apex; distance between nodus and pterostigma 16.3 mm, between pterostigma and apex 4.3 mm; pterostigma 5.9 mm long, 0.9 mm wide, with costal and posterior sides maximally widened in middle; no oblique pterostigmal brace; pterostigma covering three and a half cells; 11 postnodal cross-veins, not well aligned with eight corresponding postsubnodal cross-veins; ‘ libellulid gap ’ long; second oblique cross-vein between RP1 and RP2 only weakly oblique; 15 preserved antenodal cross-veins of first row, apparently all well aligned with those of second row, last antenodal cross-vein incomplete; distance between first antenodal crossvein and wing base 6.9 mm; distance between arculus and wing base 5.6 mm; arculus opposite an antenodal cross-vein (probably second one, but incompletely preserved); number of cross-veins between RA and RP, between arculus and nodus, unknown; one preserved Bq cross-vein between IR2 and RP2; distance between arculus and nodus 20.6 mm; base of RP 3/4 and that of IR2 16.9 mm distal of arculus; sectors of arculus (bases of RP and MA) clearly fused basally; median and submedian spaces free of crossveins, subdiscoidal cell 3.6 mm long, 2.2 mm wide and divided into five cells; discoidal triangle narrow transverse, divided into two cells, length of its costal side 1.3 mm; proximal side 4.3 mm long, distal side 5.0 mm long; 2 – 3 rows of cells in anal area; 3 – 5 rows of cells in cubito-anal area, width of cubito-anal area 2.5 mm; CuA not well defined and reaching posterior wing margin about 3.0 mm basal of nodus; MP nearly straight and reaching posterior wing margin 3.2 mm distal of nodus; four rows of cells in postdiscoidal area just distal of discoidal triangle; postdiscoidal area narrower (2.8 mm wide) in its middle part than near discoidal triangle (3.9 mm wide); Mspl straight, with one row of cells between it and MA; RP 3/4 and MA basally nearly straight but distally curved and nearly perpendicular to posterior wing margin; RP2 aligned with subnodus; oblique cross-vein ‘ O ’ 1.1 mm distal of subnodus; IR2 and RP2 with two strong undulations; IR2 and RP2 distally curved and nearly perpendicular to wing margin; area between IR2 and RP3/4 rather wide, with a nearly straight vein Rspl; two rows of cells between Rspl and IR2; area between RP1 and RP2 rather wide, but incompletely preserved, no visible ‘ reversed libellulid oblique vein ’ between RP2 and RP3/4.
