- Description:
- A new fossil genus and species of Sinoalidae, Stictocercopis wuhuaensis gen. et sp. n., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China is described, illustrated and its systematic position discussed, on the basis of four complete well-preserved specimens. The new genus distinctly differs from other sinoalids in having relatively complex wing venation and tegmen spots. The intra-specific variation in venation is also discussed. The new discovery increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds., Yan-Zhe Fu, Di-Ying Huang., and Obsahuje bibliografii

- Description:
- A new progonocimicid bug named Cicadocoris parvus sp. n. is described from the mid-Jurassic Haifanggou Formation at Daohugou, Ningcheng County, Inner Mongolia, northeastern China. It differs from other species by being distinctly smaller, veins dSc, R1 and Rs run parallel to one another and are nearly evenly spaced on left tegmen, widest length of apical half/basal half of left tegmen is 1.1 and that of right tegmen is 1.0. Thus, there are at least three species of Cicadocoris (Progonocimicidae) described from Daohugou. All these species are relatively abundant in the Haifanggou Formation and are remarkable representatives of the early Yanliao biota., Jia-Qian Jiang, Di-Ying Huang., and Obsahuje bibliografii

4. New stem-Phasmatodea from the Middle Jurassic of China

- Subject:
- Adjacivena rasnitsyni gen. n., sp. n., Phasmatodea, Susumaniidae, Heteropteryx dilatata, China, Daohugou, intra-specific variability, sexual dimorphism, fossil, and Middle Jurassic
- Language:
- English
- Description:
- Adjacivena rasnitsyni gen. n., sp. n., from the Middle Jurassic Jiulongshan Formation (Daohugou Village, Inner Mongolia, China), is described based on a set of well-preserved specimens, interpreted as two females and a male of the same species. The new taxon is assigned to the family Susumaniidae, i.e. is a candidate stem-Phasmatodea. This ordinal assignment is supported by genital elements, chiefly a putative operculum concealing the ovipositor observed in one female specimen and a putative extension of the 10th tergum with a thorn pad in the male specimen. Variation in the venation of the forewing is appreciated based on more or less complete pairs of wings and a comparison with that in the forewings of male Heteropteryx dilatata (Parkinson, 1798). This material offers new perspectives on the primary homologies of the hind wing venation of stick-insects.
