The first fossil Cydnidae (Hemiptera: Pentatomoidea) from the Late Mesozoic of China Author Yao, Yunzhi Author Cai, Wanzhi Author Ren, Dong text Zootaxa 2007 1388 59 68 journal article 10.5281/zenodo.175165 dbef60eb-496c-4485-8d7c-ac4700340e1d 1175­5326 175165 Genus Orienicydnus Yao, Cai & Ren , gen. nov. Type species. Orienicydnus hongi Yao, Cai & Ren , sp. nov. Diagnosis: Body oval, dorsum of head, pronotum, scutellum, and corium with long dense setae. Head semicircular, wider than long, subequal to pronotum in length, anterior margin with 9 primary setae; rostrum arising from apex of head, extending to posterior margin of pronotum, 4­segmented, segments subequal in thickness, first longest, basal 2/3 concealed between bucculae, second subequal to third, fourth distinctly longer than third; eyes moderately sized, subtriangular, contiguous to anterior margin of pronotum. Pronotum trapezoidal, strongly transverse, anterior angles bulging forward, without collar; femora very stout, distinctly thicker than tibiae, tibiae with dense and stout spines, tarsi 3­segmented, tarsomeres subequal in thickness, first shortest, second nearly as long as third, mid and hind coxae narrowly separated, mid and hind coxae and trochanters rounded triangular, fore and mid femora subequal to corresponding tibiae in length, hind leg longer than mid leg, hind femur distinctly shorter than hind tibia. Abdomen wider than pronotum; ovipositor long, not projecting beyond last paratergites, extending through last two abdominal segments. Distribution. China . Etymology: The generic name is a combination of the Latin oriens (“orient”) and Cydnus (the type genus of Cydnidae ). FIGURE 5. Cilicydnus robustispinus gen. & sp. nov. Paratype, Ψ, CNU­HE­LB2006299. Scale bar = 1 mm. Remarks: This new genus is similar to Cilicydnus in dorsum of head, pronotum, scutellum, and corium having long dense setae, but Orienicydnus can be easily distinguished from Cilicydnus by head subequal to pronotum in length, anterior margin of head with 9 primary setae (vs. head shorter than pronotum, without primary seta); rostrum not extending to posterior margin of pronotum, rostral segments subequal in thickness, fourth segment distinctly longer than third (vs. rostrum extending beyond posterior margin of pronotum, rostral segments differing in thickness, third segment subequal to fourth); eyes subtriangular, contiguous to anterior margin of pronotum (vs. eyes round, touching anterior margin of pronotum), and second tarsomere subequal to third (vs. shorter than third).
