New material from the Ordovician of China indicates that Inocaulis is a graptolite

Muir, L.A., Zhang, Y.-D. & Lin, J.-P. 2012. New material from the Ordovician of China indicates that Inocaulis is a graptolite. Alcheringa 37, 558–559. ISSN 0311-5518.

The problematic Early Palaeozoic fossil Inocaulis has been regarded as an alga, a graptolite and a hydroid by different authors. A new specimen from the Ordovician (late Darriwilian) of Guizhou Province (China) shows fusellar banding, confirming that it is a benthic graptolite.

First records of Wuchiapingian (Late Permian) conodonts in the Xainza area,Lhasa Block,Tibet, and their palaeobiogeographic implications

Yuan, D.X., Zhang, Y.C., Zhang, Y.J., Zhu, T.X. & Shen, S.Z., 2014. First records of Wuchiapingian (Late Permian) conodonts in the Xainza area, Lhasa Block, Tibet, and their palaeobiogeographic implications. Alcheringa 38, 546–556. ISSN 0311-5518.

Conodonts are among the best fossil groups to provide high-resolution biostratigraphic correlation and resolve the palaeobiogeographic evolution of the Permian. However, they have been rarely reported from the Lhasa Block in Tibet. Here we report the first discovery of Wuchiapingian (early Lopingian) conodonts from the Xiala Formation in the Lhasa Block, Tibet. This conodont fauna includes two genera and three species (Clarkina liangshanensis, C. orientalis, Iranognathus sp.). The conodont fauna indicates that the Xiala Formation previously assigned to the Guadalupian actually ranges from late Kungurian to late Wuchiapingian. The existence of the late Wuchiapingian conodont species Clarkina orientalis and C. liangshanensis in the Lhasa Block provides additional data to support the viewpoint that this block probably had been in a warm-water regime during the Wuchiapingian (Lopingian).

Biostratigraphical and palaeogeographical implications of Early Cambrian hyoliths from the North China Platform

Pan, B., Skovsted, C.B., Sun, H.J. & Li, G.X., 18 June 2019. Biostratigraphical and palaeogeographical implications of Early Cambrian hyoliths from the North China Platform. Alcheringa 43, 351–380. ISSN 0311-5518.

A succession of diverse hyolith assemblages comprising 10 genera and 14 species are reported from the lower Cambrian Shangwan and Sanjianfang sections of the Xinji Formation, and Xiaomeiyao section of the Houjiashan Formation, which crop out along the southern margin of the North China Platform. Most of the specimens are represented by both conchs and opercula. The identified orthothecids include Conotheca australiensis, Cupitheca holocyclata, C. costellata, Neogloborilus applanatus, N. spinatus, Tegminites hymenodes, Triplicatella disdoma, T. xinjia sp. nov. and Paratriplicatella shangwanensis gen. et sp. nov. The hyolithids comprise Protomicrocornus triplicensis gen. et sp. nov., Microcornus eximius, M. petilus, Parkula bounites and Parakorilithes mammillatus. Some anomalous taxa possess characteristics of both Hyolithida and Orthothecida, such as C. australiensis, Neogloborilus and P. triplicensis. Protomicrocornus may constitute a sister group of other hyolithids. The teeth of Parkula bounites and clavicles of Parakorilithes mammillatus are documented for the first time. The hyolith assemblages from North China are probably coeval, and can be correlated with the Cambrian upper Stage 3–lower Stage 4. Many taxa are also globally distributed and have significant potential for biostratigraphical correlations. In accordance, the hyoliths from North China reveal closest compositional similarities to faunas from eastern Gondwana, and especially South Australia. However, some taxa are shared with Laurentian assemblages suggesting cosmopolitanism, and possibly planktonic larval dispersal.

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.

Atomaria cretacea sp. nov., a new silken fungus beetle, is described and figured based on an impression fossil from the Lower Cretaceous Shixi Formation at a locality near Qingxi Town, Jiangxi Province, southern China. The new species can be referred to the extant family Cryptophagidae as supported by the tiny body size, the clubbed antenna with dilated antennomere 1, closely spaced antennal insertions, and abdominal ventrite 1 being longer than the remaining ventrites. It is placed in the extant subfamily Atomariinae based on the presence of a frontoclypeal suture and the absence of gular sutures; and tentatively in Atomaria based on its body size, sub-parallel body shape, and the presence of a frontoclypeal suture.

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.

First fossil thaneroclerid beetle from mid-Cretaceous Burmese amber (Coleoptera: Cleroidea: Thanerocleridae)

Cai, C. & Huang, D., January 2018. First fossil thaneroclerid beetle in Upper Cretaceous Burmese amber (Coleoptera: Cleroidea: Thanerocleridae). Alcheringa 42, 115–119. ISSN 0311-5518.

Thanerocleridae is a small family of Cleroidea with no fossil representatives to date. Here we describe and figure the first fossil representative of Thanerocleridae, Cretozenodosus fossilis gen. et sp. nov., from the mid-Cretaceous amber of northern Myanmar. Cretozenodosus is referred to the extant subfamily Zenodosinae as evidenced by its open procoxal cavities and transverse procoxae. Cretozenodosus has close affinities with the North American Zenodosus Wolcott, suggesting that modern Zenodosinae is probably a relict group. Our discovery of a new thaneroclerid genus from Burmese amber suggests that Thanerocleridae originated no later than the mid-Cretaceous.

Progonocimicids (Hemiptera,Coleorrhyncha) from the Middle Jurassic Haifanggou Formation,western Liaoning,northeast China support stratigraphic correlation with the Daohugou beds

Jiang, J.-Q., Cai, C.-Y. & Huang, D.-Y., October 2015. Progonocimicids from the Middle Jurassic Haifanggou Formation, western Liaoning, northeast China support stratigraphic correlation with the Daohugou beds. Alcheringa 40, XXX–XXX. ISSN 0311-5518.

The hemipteran suborder Coleorrhyncha includes only 37 extant species assigned to the family Peloridiidae. However, the suborder’s fossil record is diverse and abundant. The extinct family Progonocimicidae is very common in Middle Jurassic strata of northeastern China, especially in the Daohugou beds of Ningcheng County, Inner Mongolia, and the Haifanggou Formation in Beipiao, Liaoning Province. We re-studied the established progonocimicid species and examined 27 new specimens, indicating that the species from Daohugou are junior synonyms of those from Haifanggou. The progonocimicids from the Haifanggou Formation are assigned to two species of Cicadocoris: C. brunneus (=Mesoscytina brunnea, =Mesocimex lini) and C. sinensis (=Cicadocoris anisomeridis). Both species are common in the Daohugou beds and the Haifanggou Formation. This discovery is of significance for biostratigraphic correlation of these two lithostratigraphic units. It also contributes to our understanding of the geological age of the famous Daohugou biota, which has yielded the earliest known feathered dinosaurs and diverse early mammals.

Holocene Ostracods from the Hang Hau Formation in Lei Yue Mun,Hong Kong,and their palaeoenvironmental implications

Wang. H., Zhang, H., Cao, M. & Horne, D.J., October 2018. Holocene Ostracods from the Hang Hau Formation in Lei Yue Mun, Hong Kong, and their palaeoenvironmental implications. Alcheringa 43, 320–333. ISSN 0311-5518.

The Holocene Hang Hau Formation is the youngest part of the Quaternary succession in Hong Kong and yields abundant and diverse ostracods. This study of ostracod assemblages from two cores in Lei Yue Mun identifies eight genera and nine species of marine Ostracoda that were previously unreported from the Hang Hau Formation, increasing the known diversity from 67 to 76 species. Among these species, Neocyprideis timorensis (Fyan 1916) is reported for the first time in China. The recovery of abundant juvenile and adult specimens has facilitated illustration and discussion of an ontogenetic series for Neomonoceratina delicata Ishizaki & Kato, 1976, extending from the A-5 instar (fourth moult after hatching) to the sexually dimorphic A (adult) instar. Palaeoenvironmental analysis of the ostracod assemblages supports and strengthens previous interpretations indicative of a warm, shallow, nearshore-marine environment.

New damselflies (Odonata: Zygoptera: Hemiphlebiidae,Dysagrionidae) from mid-Cretaceous Burmese amber

Zheng, D., Zhang, Q., Nel, A., Jarzembowski, E.A., Zhou, Z., Chang, S.-C. &; Wang, B., May 2016. New damselflies (Odonata: Zygoptera: Hemiphlebiidae, Dysagrionidae) from mid-Cretaceous Burmese amber. Alcheringa XX, xxx–xxx. ISSN 0311-5518

Two damselflies, Burmahemiphlebia zhangi gen. et sp. nov. and Palaeodysagrion cretacicus gen. et sp. nov., are described from the mid-Cretaceous Burmese amber. Burmahemiphlebia zhangi is the first record of Hemiphlebiidae from this amber, although the family was cosmopolitan during the Mesozoic. It can be readily distinguished from all other members of Hemiphlebiidae in having very short MP and CuA veins, and in its rectangular discoidal cell. The new fossils support the view that hemiphlebiid damselflies were one of the dominant groups of Zygoptera during the Mesozoic. Palaeodysagrion cretacicus is the first dysagrionid damselfly from Burmese amber and the second Mesozoic representative of this predominantly Paleogene group. It differs from other members of Dysagrionidae in having a unique elongate discoidal cell. These new finds increase the diversity of damselflies in mid-Cretaceous Burmese amber.

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.

A new damsel-dragonfly (Odonata: Anisozygoptera: Campterophlebiidae) from the earliest Jurassic of the Junggar Basin,northwestern China

Zheng, D., Wang, H., Nel, A., Dou, L., Dai, Z., Wang, B. & Zhang, H. 27 June 2019. A new damsel-dragonfly (Odonata: Anisozygoptera: Campterophlebiidae) from the earliest Jurassic of the Junggar Basin, northwestern China. Alcheringa XX, X–X. ISSN 0311-5518.

A new genus and species of campterophlebiid damsel-dragonfly, Jurassophlebia xinjiangensis gen. et sp. nov., is described from the Lower Jurassic Badaowan Formation in the Junggar Basin, northwestern China. Jurassophlebia differs from all other campterophlebiid genera in having PsA in the same orientation as the distal branch of AA, and in its uniquely open subdiscoidal cell with very acute apical angle in the hind wing. The new discovery adds to the Asian diversity of damsel-dragonflies in the earliest Jurassic.

Campterophlebiidae is the most diverse family of fossil odonatans in China with ten genera recovered mostly from Middle Jurassic strata of Inner Mongolia. We describe a well-preserved campterophlebiid damsel-dragonfly from the Middle Jurassic Yanan Formation in Shanxi Province, northwestern China. This discovery adds to the diversity of Campterophlebiidae and identifies a new Middle Jurassic insect fossil locality in China. Within Campterophlebiidae, the new taxon most closely resembles Ctenogampsophlebia from the Middle Jurassic of Inner Mongolia but differs from other genera in having vein AA with four parallel posterior branches uncrossed in the anal triangle.

Remarks on the pattern of septal insertion in rugose corals

Wang, G., Percival, I.G. & Li, R., 25.2.2015. Remarks on the pattern of septal insertion in rugose corals. Alcheringa 39, xxx–xxx. ISSN 0311-5518

Well-preserved specimens of the Hirnantian (latest Ordovician) rugose coral Lambeophyllum? corniculum He from the Yangtze Platform of South China, clearly show how catasepta (minor septa) are inserted, confirming the model proposed by Weyer in the 1970s. Our observations indicate the insertion of counter lateral septa and their neighbouring catasepta on the counter side takes place in exactly the same manner as that of the subsequent metasepta and catasepta. We propose abandoning the use of the term counter lateral septa. Therefore, exclusion of the pair of counter lateral septa reduces the number of protosepta from six to four.

A new family of ‘libelluloid’ dragonflies from the Middle Jurassic of Daohugou,northeastern China (Odonata: Anisoptera: Cavilabiata)

Nel, A. & Huang, D.Y., 8.5.2015. A new family of ‘libelluloid’ dragonflies from the Middle Jurassic of Daohugou, northeastern China (Odonata: Anisoptera: Cavilabiata). Alcheringa 39, 525–529. ISSN 0311-5518

A new well-preserved Middle Jurassic fossil of Cavilabiata is described and attributed to a new family (Daohugoulibellulidae), genus and species (Daohugoulibellula lini), from the Daohugou beds of China. Together with examples of Juralibellulidae from the same outcrop, they represent the oldest records of the Cavilabiata. The potential closest relative of the new family could be the Late Jurassic Nannogomphidae, suggesting a significant diversity of Cavilabiata during the Middle Jurassic.

Jarzembowski, Edmund A., Wang, B. &; Zheng, D., October 2017. A slender new archaic beetle in Burmese amber (Coleoptera: Archostemata). Alcheringa 42, 110–114. ISSN 0311-5518.

A new archostematan beetle, Clessidromma palmeri gen. et sp. nov. (Insecta: Coleoptera) is described from mid-Cretaceous Burmese amber from northern Myanmar. It has a uniquely specialized body form for which a new stem tribe, Clessidromatini trib. nov., is proposed in the subfamily Ommatinae of the family Cupedidae sensu lato.

Phylogenetic analysis of a new fossil Notonectidae (Heteroptera: Nepomorpha) from the Late Jurassic of China

Zhang W.T., Yao Y.Z. & Ren D., June 2012. Phylogenetic analysis of a new fossil Notonectidae (Heteroptera: Nepomorpha) from the Late Jurassic of China. Alcheringa, 239–250. ISSN 0311-5518.

A new fossil species Notonecta vetula sp. nov. is described and illustrated using nymph and adult fossil specimens collected from the Upper Jurassic Chijinqiao Formation, Yumen City, Gansu Province, China. A phylogenetic analysis, based on a combination of fossil and extant backswimmers, was conducted to confirm the position of the new fossil within the Notonectidae.

A new dysagrionid damselfly (Odonata: Zygoptera: Palaeodysagrion) from mid-Cretaceous Burmese amber

AUTHOR, N. &; AUTHOR, P. December 2017. Article title. Alcheringa 42, 301-305. ISSN 0311-5518. Dysagrionidae are common in Paleogene sedimentary rocks, but rarely recorded in the Mesozoic. This family, however, is diverse in Burmese amber. A new dysagrionid damselfly, Palaeodysagrion youlini Zheng, Chang &; Chang sp. nov., is described here based on a well-preserved specimen (holotype) in Burmese amber. The new damselfly provides wing apex and body characters for Palaeodysagrion. It differs from Palaeodysagrion cretacia in having Arc slightly distal of Ax2, the midfork slightly basal of the nodus, Cr and Sn almost perpendicular to RA and RP and in having a simple wing system. This is the fourth dysagrionid damselfly described from the Burmese amber.

A new species of Loricera Latreille from Eocene Baltic amber (Coleoptera: Carabidae: Loricerinae)

Cai, C., Liu Y. & Huang, D., February 2017. A new species of Loricera Latreille from Eocene Baltic amber (Coleoptera: Carabidae: Loricerinae). Alcheringa xx, xxx-xxx. ISSN 0311-5518.

Loricerinae is a small, distinctive subfamily of ground beetles, comprising only one genus Loricera Latreille. Only one fossil species is known to date. Here, we describe a new species, Loricera groehni sp. nov., belonging to Loricera based on a well-preserved adult in Eocene Baltic amber. Loricera groehni is tentatively attributed to the obsoleta group of the subgenus Loricera s.str. based on the relatively long antennomere 3 and punctate elytral interval 7. The discovery of a new species morphologically close to the extant Loricera species from western China and northern India suggests that the obsoleta group was more widespread in the Eocene than it is at present. The distribution pattern of Chinese Loricera is probably relictual. The fossil species, possessing conspicuous stiff setae on the basal antennomeres, was probably a specialized predator of springtails.
