Etymology. The specific name reticulatus is a Latin word meaning “reticulated”, referring to the reticulated pattern present on forewing of this species.

Material. Holotype. CNU−NEU−NN2016005 ( Fig. 1A–B ); Paratype. CNU−NEU−NN2016008P/C ( Fig. 1C ), CNU−NEU−NN2016009 ( Fig. 1D ).

Type locality and horizon. Daohugou Village , Shantou Township , Ningcheng County, Inner Mongolia, China; Jiulongshan Formation , Callovian-Oxfordian boundary, late Middle Jurassic .

Diagnosis. As for the genus due to monotypy.

Description. Forewing elongated, ca. 39 mm long and 13 mm wide; membrane dark, with the distinct transparent patches along anterior and posterior margins; trichosors well-defined in most margin except for the proximal half of anterior margin; humeral vein recurrent, producing 4–5 short crossveins; costal crossveins with the distal forks, and absence of interlinked crossveins in between; space between Sc and RA relatively broad, sc-sa crossvein absent; ra-rp crossveins numerous; RP with 18 close-set branches, crossveins in RP area numerous and irregularly arranged, only one outer gradate series present; M forked close to the divergence of RP1 from RP; MA with 4 distal branches, MP with 6 distal branches; Cu proximally branched; CuA with about 9 oblique pectinate branches; CuP dichotomously branched; A1–A3 multi-dichotomously branched distally.

Only forewing present, body features unknown.
