Type materials. Holotype, ɗ, CNU-HE-LB2006023 (dorsoventrally compressed); paratypes, 1 ɗ, CNU-HE-LB2006024 (dorsoventrally compressed), 5 Ψ, CNU-HE- LB2006022/029/030/033/0364 (dorsoventrally compressed).

Locality and horizon. Yixian Formation, Late Jurassic Chaomidian Village, Beipiao City, Liaoning Province, China.

Etymology. The name is derived from the Latin ciliatus (cilia), because the species’ antenna and pronotum are densely beset with setae.
