Genus Elektrogomphaeschna gen. nov.

Type species. Elektrogomphaeschna peterthieli sp. nov.

Other species. Elektrogomphaeschna annekeae sp. nov.

Etymology. Named after Elektron, Greek name for amber, and the extant dragonfly genus Gomphaeschna . Gender feminine.

Diagnosis. Ax2 not far distal of arculus; only a single secondary antenodal between Ax1 and Ax 2 in forewing and two in hindwing; triangles elongate and two-celled in both wings; hypertriangles and subtriangles free; pterostigmata short (spanning 2–3 cells), basal and distal sides not parallel, with very oblique but straight brace; RP1 and RP2 basally not parallel but weakly divergent; a long and straight vein IR1 with only one row of cells between it and RP1; RP2 and IR2 smoothly curved and smoothly diverging, not undulating and abruptly diverging; RP3/4 and MA not undulate; 3–4 cells between apex of discoidal triangle and base of Mspl; one row of cells between Mspl and MAa and between Rspl and IR2.

Comment. Attribution of the two holotypes of the two new species to the same genus is based on the great general similarity in their wing venation and especially the very unique derived character states of IR1 and RP2.
