- Jurahylobittacus astictus sp nov. (Figs 2A–E, 3C–D) Etymology. This species is named astictus after having no maculae on wings. Material. Holotype CNU-M-NN2007002-1 and CNU-M-NN2007002-2, positive and negative (coll. Shih Chungkun), deposited at the Key Lab of Insect Evolution & Environmental Changes, the College of Life Sciences, Capital Normal University (CNU), Beijing, China. Horizon and locality. Jiulongshan Formation, Middle Jurassic, Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China. Diagnosis. Sc-r at about as long as its length before end of Sc; no cross-vein between R 2 and R 1; and no maculae on wings. Description. Lateral view of a complete insect. Rostrum slender; abdomen long and slender, slightly beyond wing tip (Fig. 2 A-C). Wings. Basal part of forewing narrow; gradually broadening from base towards rounded apex; pterostigma slightly dark; sc-r is close to the tip of Sc; M 1+2 dividing far beyond R 4+5; one cross-vein between R 2+3 and R 4; two cross-veins R 4 and R 5; two cross-veins between R 5 and M 1; two cross-veins between M 1 and M 2; two cross-veins between M 2 and M 3; one cross-vein between M 3 and M 4; two cross-veins between CuA and CuP; two cross-veins connecting 1A and 2A; 2A extending almost to level of origin of M; and vein 3A absent (Fig. 2D). Hindwings seem to be identical to the forewings in the venation, but their Sc short, ending distally before the fork of Rs ( Fig. 2E). Abdomen. At least nine visible segments in lateral view (Fig. 2C). Terminal abdominal segments were well preserved, basistyles, aedeagus, cercus and epiandrial lobe visible (Fig. 3 C-D). Body 18 mm long, forewing 12.6 mm long, 3.0 mm wide; hind wing 10.3 mm long, 3.0 mm wide.
