Description:
Cryptic immigrants are common species incorporated in near-natural biocoenoses that occur only in Holocene, mostly very recent deposits, being absent from older (Pleistocene) formations. This is true of Alinda biplicata, Oxychilus cellarius and other presented species. This also applies to isolated occurrences of Itala ornata or Cochlodina commutata that entered the Bohemian Uplands by aerial dispersal from the south. In the Pleistocene, the very early appearance of some southern species (e.g. Drobacia banatica) from the very be-ginning of the interglacial periods is reminiscent of modern snail invasions. How-ever, the former was initiated by the abrupt increase in temperature and moisture., Vojen Ložek, and 1 barev. fot., 10 čb. fot.

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

Language:

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
