New material. NIGP203295, part and counterpart of a well-preserved male dragonfly, with nearly complete body, left forewing and hindwing, and very basally-preserved right forewing and hindwing.
Emended diagnosis. Forewing discoidal and subdiscoidal triangles three-celled and strongly transverse; hindwing discoidal and subdiscoidal triangles free; unicellular anal triangle; three rows of cells in postdiscoidal area before midfork; IR1 originated below pterostigma, zigzagged and poorly defined; IR2 originating from RP3/4; pterostigma very long and covering more than eight cells; cerci elongated.
Description. Body length from head to tip of abdomen 76.4 mm; head 5.2 mm long and 5.7 mm wide; thorax 12.8 mm long and maximum 5.6 mm wide; abdomen elongated, 54.7 mm long and maximum 4.4 mm wide.
Forewing 54.0 mm long and maximum width 9.4 mm; distance from base to arculus 4.1 mm, from base to nodus 29.6 mm, and from nodus to pterostigma 12.1 mm; pterostigma 6.0 mm long and 0.8 mm wide, covering at least eight cells; primary antenodal crossveins stronger than secondary antenodal crossveins; Ax0 near wing base, Ax1 3.5 mm distal of Ax0 and 0.6 mm basal of arculus, Ax2 8.4 mm distal of Ax1, opposite distal angle of discoidal triangle; five secondary antenodal crossveins present between Ax1 and Ax2; at least 10 antenodal crossveins visible between costal margin and ScP distal of Ax2, not aligned with nine antenodal crossveins between ScP and RA; eight postnodal crossveins present, not aligned with nine postsubnodal crossveins in second row; RP1 and RP2 closely parallel up to pterostigma with one row of cells in-between and two rows below level of mid-pterostigma; RP2 and IR2 closely parallel, with mostly one row of cells in-between, but two rows near wing margin; primary oblique vein ‘O’ absent and secondary oblique vein well present; no well-defined Rspl and Mspl; RP3/4 and MA basally parallel, sigmoidal, with a single row of cells in-between below second ‘O’, area between them expanded distally; postdiscoidal area with three rows of cells before midfork, expanded distally; MP and CuAa parallel, with a single row of cells in-between; median space free; CuP-crossing 1.1 mm basad arculus and 3.9 mm distad wing base; discoidal triangle elongated and wide, divided into three smaller cells, with length of anterior side 3.6 mm and of basal side 3.4 mm; subdiscoidal triangle divided into three cells; hypertriangle free; CuAa with four well-defined posterior branches; anal area with two rows of cells.
Hindwing, 51.6 mm long and maximum width 9.6 mm; distance from base to arculus 3.5 mm; Ax0 near wing base; Ax1 2.4 mm distal of Ax0 and 0.8 mm basal of arculus; Ax2 4.8 mm distal of Ax1; pterostigma elongated and well braced, 7.5 mm long and 0.7 mm wide, covering at least nine cells; anal triangle one-celled.
