A new fossil petalurid dragonfly (Odonata: Petaluroidea: Aktassiidae) from the Cretaceous of China

LI, Y.J., HAN, G., NEL, A. REN, D., PANG, H. & LIU. X.L., September 2012. A new fossil petalurid dragonfly (Odonata: Petaluroidea: Aktassiidae) from the Cretaceous of China. Alcheringa 36, 321–324. ISSN 0311-5518.

The new petalurid species Pseudocymatophlebia boda is described from Lower Cretaceous strata of Inner Mongolia, China. It provides additional morphological characters for this genus, which has been previously recorded from the Lower Cretaceous of England. Together with Aktassia, it is the second aktassiid genus with a very wide distribution, even though this family remains known only from Eurasia. Furthermore, a new name, Brachaktassia gen. nov., is proposed to replace the brachiopod genus Aktassia Popov, 1976.     

Two new Middle Jurassic species of orthophlebiids (Insecta: Mecoptera) from Inner Mongolia,China

QIAO, X., SHIH, C.K. & REN, D., December 2012. Two new Middle Jurassic species of orthophlebiids (Insecta: Mecoptera) from Inner Mongolia, China. Alcheringa 36, 467–472. ISSN 0311-5518.

Two new species of the extinct family Orthophlebiidae, Orthophlebia nervulosa sp. nov. and Orthophlebia stigmosa sp. nov., are described and illustrated. These well-preserved specimens were collected from the Middle Jurassic Jiulongshan Formation near Daohugou Village, Inner Mongolia, China. Morphological characters shown in these well-preserved specimens highlight the diversity of orthophlebiids during the Middle Jurassic and provide data for future phylogenetic studies of orthophlebiids.     

Two new species of Mesosciophilidae (Insecta: Diptera: Nematocera) from the Yanliao biota of Inner Mongolia,China

Wang, Q., Zhao, Y.Y. & Ren, D., December 2012. Two new species of Mesosciophilidae (Insecta: Diptera: Nematocera) from the Yanliao biota of Inner Mongolia, China. Alcheringa 36, 509–514. ISSN 0311-5518.

Two new species assigned to Mesosciophila Rohdendorf and Paramesosciophilodes Zhang in the Mesosciophilidae are described and illustrated: Mesosciophila sigmoidea sp. nov. and Paramesosciophilodes aequus sp. nov. They are established based on fossil specimens with bodies and complete wings. Both were collected from the Middle Jurassic, Jiulongshan Formation at Daohugou, Inner Mongolia, China.     

Poljanka strigosa,a new species of Protopsyllidiidae (Hemiptera,Sternorrhyncha) from the Middle Jurassic of China

Yang, G., Yao, Y.Z. & Ren, D., iFirst. Poljanka strigosa, a new species of Protopsyllidiidae (Hemiptera, Sternorrhyncha) from the Middle Jurassic of China. Alcheringa, 1–6. ISSN 0311-5518.

A new fossil species, Poljanka strigosa sp. nov., of the extinct family Protopsyllidiidae is described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. The new species is characterized by wings bearing long, stiff setae that are evident as stained impressions in the fine sedimentary rock. Comparison between Protopsyllidiidae and extant psylloids suggests that Protopsyllidiidae is probably closely related to extant psylloids.     

Two new species of Nevania (Hymenoptera: Evanioidea: Praeaulacidae: Nevaniinae) from the Middle Jurassic of China

Two new species of Nevania Zhang & Rasnitsyn 2007 Zhang, H.C. & Rasnitsyn, A.P., 2007. Nevaniinae subfam. n., a new fossil taxon (Insecta: Hymenoptera: Evanioidea: Praeaulacidae) from the Middle Jurassic of Daohugou in Inner Mongolia, China. Insect Systematics & Evolution 38, 149–166.[Crossref], [Web of Science ®] , [Google Scholar], Nevania perbella sp. nov. and Nevania aspectabilis sp. nov., are described and illustrated. They are assigned to Nevania based on their unique morphological characters: forewing venation complete; 2A complete; metasoma with first and second segments long and tube-like. A key to the known species of Nevania is provided. These fossils, collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou in Inner Mongolia, China, broaden the known diversity of this genus in mid-Mesozoic ecosystems.     

Repairs to an injured early Middle Cambrian Trilobite,Elkedra area,Northern Territory

Wang, Y., Shih, C., Szwedo, J. &; Ren, D. iFirst article. New fossil palaeontinids (Hemiptera, Cicadomorpha, Palaeontinidae) from the Middle Jurassic of Daohugou, China. Alcheringa, 1–12. ISSN 0311-5518.

A new genus and species assigned to the extinct family Palaeontinidae, Synapocossus sciacchitanoae Wang, Shih &; Ren, is described from the Middle Jurassic of Daohugou in Inner Mongolia, China. This new genus is established based on well-preserved fossil specimens with body and complete forewings and hind wings. It differs from other described genera by the following characters: small body size, RP and M₁ coalescing for an interval on the forewings and M_3 + 4 without bifurcation on the hind wings. The RP coalescence with M₁ in Synapocossus Wang, Shih &; Ren previously reported only in Turgaiella Becker-Migdisova &; Wootton, seems to be associated with strengthening of the anterior wing margin. The intra-specific and individual variations of Synapocossus and numerous other insect fossils of northeastern China probably indicate long-lasting ecological stresses and a competitive environment in the Middle Jurassic to Early Cretaceous ecosystems.     

New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou,Inner Mongolia,China

Fu, Y., & Huang, D., December 2018. New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou, Inner Mongolia, China. Alcheringa 43, 246–256. ISSN 0311-5518.

A new fossil genus with three species of Sinoalidae, Parasinoala daohugouensis gen. et sp. nov., Parasinoala minuta gen. et sp. nov., Parasinoala magnus gen. et sp. nov., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China, is described and illustrated. The new genus differs from other sinoalids by the tegmen with RA having 2–3 branches, MP with 3–4 branches and MP of hind wings with two branches, which indicates the terminal branches of RA and MP are highly variable within Sinoalidae. The new discovery greatly increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds.

Rariellidae,a new family of Rhynchoporoidea (Brachiopoda) with a restudy of the type genus Rariella Zhang 1981, from the Emsian (Early Devonian) of Inner Mongolia,north China

Rong Jla-yu & Zhang Yan. 1994:03:28. Rariellidae, a new family of Rhynchoporoidea (Brachiopoda) with a restudy of the type genus Rariella Zhang 1981. from the Emsian (Early Devonian) of Inner Mongolia, north China. Alcheringa 18. 135–146. ISSN 0311-5518

Reinvestigation of the type material of Rariella Zhang 1981, from the late Emsian (Early Devonian) of western Inner Mongolia, north China, shows that it should be attributed to the rhynchoporoids rather than the retziids since it possesses a punctate shell without laterally directed spiralia and lacks evidence for the brachiophore supports being in the fonn of a loop, as in the terebratuloids. A new family Rariellidae based on Rariella as the type genus is characterized by a spondylium apically in the pedicle wlve and a cardinal process on a septalium in the brachial valve. The fauna containing Rariella is mainly endemic to Inner Mongolia and developed at depths within Benthic Assemblage 2 to inner BA 3.

Huang, D.-Y. &; Nel, A., December, 2008. New ‘Grylloblattida’ related to the genus Prosepididontus Handlirsch, 1920 Handlirsch, A. 1920. “Kapitel 7. Palaeontologie. C.”. In Schröder Handbuch der Entomologie, III, 117–304. G. Fischer, Jena.  [Google Scholar] in the Middle Jurassic of China (Insecta: Geinitziidae). Alcheringa 32, 395–403. ISSN 0311-5518.

On the basis of well-preserved nearly complete specimens, two new genera and species Sinosepididontus chifengensis and Megasepididontus grandis, both closely related to the Early Jurassic geinitziid genus Prosepididontus, are described. The new material was collected from the Middle Jurassic Jiulongshan Formation near the Daohugou Village, Ningcheng County, Inner Mongolia, northeast China. New body and leg structures are described for these Chinese taxa. They were previously unknown in other Geinitziidae. The new data indicate that the extinct ‘Grylloblattida’ contained heterogenous groups.     

New fossil sawflies (Hymenoptera,Xyelidae) from the Middle Jurassic of northeastern China

Magnaxyela rara gen. et sp. nov. and Abrotoxyela curva sp. nov. (Xyelidae, Macroxyelinae, Gigantoxyelini) are described from the Middle Jurassic Jiulongshan Formation at Daohugou Village, Inner Mongolia, China. The two new species are confidently assigned to tribe Gigantoxyelini of subfamily Marcroxyelinae based on their wing venation and various other morphological characters. Magnaxyela rara is established based on the following forewing characters: pterostigma sclerotized completely, Sc two-branched and meeting R before origin of Rs, 1-Rs as long as 1-M, but shorter than Rs?+?M, R curved bewteen 1r-rs and 2r-rs and cell 2r longer than 1r. Abrotoxyela curva is differentiated from congeneric forms by the two-branched vein Sc of the forewing, Sc2 short and inclined towards the base of the wing, 1-Rs, 1-M and Rs?+?M nearly equal in length, crossvein 1m-cu longer than 1cu-a. The fossils described herein increase the diversity of the Mesozoic Xyelidae.

Revision and two new species of Itaphlebia (Nannochoristidae: Mecoptera) from the Middle Jurassic of Inner Mongolia,China

Cao, Y., Shih, C., Bashkuev, A. & Ren, D., September 2015. Revision and two new species of Itaphlebia (Nannochoristidae: Mecoptera) from the Middle Jurassic of Inner Mongolia, China. Alcheringa 40, XX–XX. ISSN 0311-5518.

Two new species of Itaphlebia Sukatsheva, 1985, Itaphlebia longiovata and I. amoena (Nannochoristidae Tillyard, 1917), are described and illustrated from the Middle Jurassic Jiulongshan Formation of Daohugou, Inner Mongolia, China. Previously described Middle Jurassic nannochoristid genera, Chrysopanorpa Ren in Ren et al., 1995 and Protochoristella Sun, Ren & Shih, 2007b, together with Stylopanorpodes and Netropanorpodes Sun, Ren & Shih, 2007a (originally assigned to Mesopanorpodidae) are revised and considered to be synonyms of Itaphlebia. The following tentative species synonymies are proposed: Protochoristella formosa and Stylopanorpodes eurypterus = Itaphlebia ruderalis (Ren in Ren et al., 1995), comb. nov.; Netropanorpodes sentosus = I. jeniseica Novokshonov, 1997a, syn. nov.; and Protochoristella polyneura = I. multa Novokshonov, 1997a, syn. nov. Netropanorpodes decorosus is transferred to Itaphlebia. These new species, new material and the new combinations broaden the diversity of the Itaphlebia in mid-Mesozoic ecosystems and provide new characters enabling amendment of the generic diagnosis.

Two new species, Acisarcuatus locellatus (Necrotauliidae) and Liadotaulius limus (?Philopotamidae) are described. They were collected from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Ningcheng County, Inner Mongolia, China. In addition, we interpret Karatauliodes to be a junior synonym of Necrotaulius and propose Necrotaulius minutus (Sukatsheva, 1968) comb. nov. We propose transferring Necrotaulius korujensis and Necrotaulius shewjensis to Liadotaulius as Liadotaulius korujensis (Sukatsheva, 1990) comb. nov. and Liadotaulius shewjensis (Sukatsheva, 1990) comb. nov. Based on newly described taxa and the new combinations proposed, we summarize seven known genera with 24 species within Necrotauliidae and provide a key to the genera of this family.

On the integration of Ordovician conodont and graptolite biostratigraphy: new examples from Gansu and Inner Mongolia in China

Wang, Z.H., Bergström, S.M., Zhen, Y.Y., Chen, X. & Zhang, Y.D., 2013. On the integration of Ordovician conodont and graptolite biostratigraphy: New examples from Gansu and Inner Mongolia in China. Alcheringa 37, 510–528. ISSN 0311-5518.

Few Ordovician successions in the world contain both biostratigraphically highly diagnostic conodonts and graptolites permitting an integration between standard biozones based on these fossil groups. The Sandbian Guanzhuang section in the vicinity of Pingliang in the Gansu Province has an outstanding graptolite record through most of the Nemagraptus gracilis and Climacograptus bicornis graptolite biozones. Calcareous interbeds in the succession yield biostratigraphically important conodonts, including some species used for biozonations in Baltoscandia and the North American Midcontinent. Likewise, the middle–upper Darriwilian Dashimen section in the Wuhai region of Inner Mongolia hosts both diverse graptolites of the Pterograptus elegans, Didymograptus murchisoni and lowermost Nemagraptus gracilis biozones, and conodonts of Midcontinent and Baltoscandic types. The distribution patterns of these index fossil groups provide an unusual opportunity to closely correlate conodont and graptolite biozones in the middle to upper Darriwilian to Sandbian interval. For instance, the base of the C. bicornis Biozone is approximately coeval with the base of the Baltoscandic B. gerdae Subbiozone and a level near the middle of the North American P. aculeata Biozone.

Jurorhizophagus alienus gen. et sp. nov., a new fossil root-eating beetle, is described and figured based on an exceptionally well-preserved impression fossil from the Middle Jurassic Daohugou beds (ca 165 Ma), Inner Mongolia, northeastern China. It represents the earliest fossil Monotomidae known to date. Jurorhizophagus can not be assigned to either of two subfamilies Monotominae or Rhizophaginae based on the unique combination of many unusual characters, including an 11-segmented antenna with a 3-segmented club, the presence of a distinct frontoclypeal suture and transverse pronotum with a median longitudinal groove. The discovery of a new genus from the Middle Jurassic highlights the antiquity of Monotomidae and provides new information about the phylogenetic relationships between Monotomidae and its allied families.

A new fossil sinoalid species from the Middle Jurassic Daohugou beds (Insecta: Hemiptera: Cercopoidea)

Fu, Y., Cai, C. & Huang, D., October 2017. A new fossil sinoalid species from the Middle Jurassic Daohugou beds (Insecta: Hemiptera: Cercopoidea). Alcheringa 42, 94–100. ISSN 0311-5518.

A new fossil species, Luanpingia daohugouensis sp. nov., belonging to the family Sinoalidae is described from the Middle to Upper Jurassic Daohugou beds of Inner Mongolia, China, on the basis of two well-preserved complete specimens. The described species of Sinoalidae are reviewed and Jiania gracila is considered a junior synonym of Jiania crebra. The new discovery increases the palaeodiversity of sinoalids from the Daohugou beds. It also indicates stratigraphic correlation between the Daohugou beds, the Haifanggou Formation at Haifeng, Beipiao City, West Liaoning Province, and the Jiulongshan Formation at Zhouyingzi, Luanping County, Hebei Province. All of these units host the ‘early assemblage’ of the Yanliao biota.

Umkomasia (megasporophyll): part 1 of a reassessment of Gondwana Triassic plant genera and a reclassification of some previously attributed

The genus Umkomasia, a megasporophyll, belonging to the pteridosperms (seed ferns) in the family Umkomasiaceae (Corystospermaceae), is reassessed comprehensively worldwide. All previous records are analysed. Certain fertile structures previously attributed are reclassified. Umkomasia is shown to be restricted to the Triassic of Gondwana where it is associated with the genus Pteruchus, a microsporophyll, and the genus Dicroidium, a vegetative leaf. It is well represented from Argentina, Australia and southern Africa where the Molteno Formation is by far the most comprehensively sampled with eight species described. Two specimens from the upper Permian of India attributed to Umkomasia are reclassified as cf. Arberiopsis sp. A whorled fertile structure from Antarctica, previously assigned to Umkomasia, is reclassified in a new genus as Axsmithia uniramia. Another compression fossil and the permineralized Umkomasia resinosa remain as valid records from Antarctica. The material described as Umkomasia from the Triassic of China is reclassified as Stenorachis asiatica. The Lower Jurassic record from Germany is placed in a new genus as Kirchmuellia franconica. The records of Umkomasia sp. from the Rhaetic of Germany are reclassified as cf. Kirchmuellia sp. and the single specimen from the Jurassic of Libya as genus et sp. indet. The Lower Cretaceous record from Mongolia has been reclassified by other researchers as Doylea mongolica. A pictorial key to Umkomasia species is provided, geographic and stratigraphic distributions are tabulated.

A new species of Aboilinae (Orthoptera: Prophalangopsidae), Aboilus perbellus, is described and illustrated based on three well-preserved forewings recovered from the Middle–Upper Jurassic Daohugou beds of Inner Mongolia, China. The new species differs from all congeneric forms in its special forewing coloration and features of its wing venation. To date, three types of forewing coloration have been found among different species of Aboilus at Daohugou, suggesting that these taxa inhabited different ecotopes.     

Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae)

Cai, C. & Huang, D., September 2016. Omma daxishanense sp. nov., a fossil representative of an extant Australian endemic genus recorded from the Late Jurassic of China (Coleoptera: Ommatidae). Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Omma Newman is an extant ommatid genus currently endemic to Australia. A new Omma species, O. daxishanense sp. nov. is described and illustrated based on a compression fossil from the Upper Jurassic Tiaojishan Formation at Daxishan, a fossil locality well known for yielding mammals, feathered dinosaurs and diverse pterosaurs. Omma daxishanense is very similar morphologically to the extant O. sagitta, but differs from the latter by its broader body and prominent temples. The new discovery documents the first valid Omma species from the Mesozoic of China and highlights the antiquity and palaeodiversity of the extant Australian endemic genus.
