A new diminutive euphyllophyte from the Middle Devonian of West Junggar,Xinjiang, China and its evolutionary implications

Xu, H.-H., Wang, Y., Tang, P. & Wang, Y., May 2017. A new diminutive euphyllophyte from the Middle Devonian of West Junggar, Xinjiang, China and its evolutionary implications. Alcheringa 41, 524–531. ISSN 0311-5518.

A diminutive euphyllophyte, Douaphyton levigata gen. et sp. nov., is described from the upper Middle Devonian (Givetian) Hujiersite Formation of West Junggar, Xinjiang, China. The plant consists of more than three orders of axis branching, each axis being less than 2 mm wide. The second-order axes are short, laterally and alternately attached to the main axis. The third-order axes are paired and anisotomously divided, bearing the vegetative appendages or the fertile units. The fertile unit consists of a short recurved axis giving off up to four short pedicels along one side, each of which bears one to four pairs of terminal sporangia. Douaphyton has a three-dimensional branching system that has an intermediate form in the evolutionary context of euphyllophytes and lignophytes. It is also proposed that complex branching developed in multiple groups in the Middle Devonian.

The first damsel-dragonfly (Odonata: Isophlebioidea: Campterophlebiidae) from the Middle Jurassic of Shaanxi Province,northwestern China

ZHENG, D., DONG, C., WANG, H., YE, Y., WANG, B., CHANG S-C. & ZHANG, H., May 2017. The first damsel-dragonfly (Odonata: Isophlebioidea:Campterophlebiidae) from the Middle Jurassic of Shaanxi Province, northwestern China. Alcheringa 41, 509–513. ISSN 0311-5518.

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.

A new early Silurian brachiopod genus,Thulatrypa, from Norway and South China,and its palaeobiogeographical significance

Huang, B., Baarli, B.G., Zhan, R.B. & Rong, J.Y., October 2015. A new early Silurian brachiopod genus, Thulatrypa, from Norway and South China, and its palaeobiogeographical significance. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

The smooth atrypoid brachiopod Thulatrypa gen. nov. incorporates two species, a younger (T. gregaria) from Norway, and an older (T. orientalis) from South China, which collectively span the middle Rhuddanian through Aeronian. In Baltica, the genus thrived just below the storm wave base in a tropical BA4 setting extending slightly into BA3 and BA5 respectively, whereas in South China, its representative occurs in a much shallower assemblage (BA2–3). Their palaeobiogeographical implications are carefully investigated. This study supports the arguments that Thulatrypa may have originated in South China in the middle Rhuddanian and extended its range to eastern Baltica in the late Rhuddanian. Larvae may have drifted along a channel from the east to the southwest of Baltica, which supports the reconstructions of palaeocurrents in the early Silurian in previous palaeogeographical studies.

An isolated turtle xiphiplastron similar to that of Puppigerus sp. is described from the upper Oligocene (27.3–25.2 Ma) Pomahaka Formation near Tapanui, Otago, New Zealand. The bone is unlike any previously described turtle from the Cenozoic of New Zealand and is from a newly recognized estuarine vertebrate locality. It represents the first Oligocene cheloniid turtle bone described from the southwest Pacific.

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.

Revised conodont and fusuline biostratigraphy of the Bamchi Formation (Pyongan Supergroup) at the Bamchi section,Yeongwol and the Carboniferous–Permian boundary in South Korea

Wang, Q., Wang, Y., Qi, Y., Wang, X., Choh, S.J., Lee, D.C. & Lee, D.J., November 2017. Yeongwol and the Carboniferous–Permian boundary in South Korea. Alcheringa 42, 245–258. ISSN 0311-5518

Six conodont and one fusuline zones are recognized on basis of a total of 25 conodont and 13 fusuline species (including seven unidentified species or species given with cf. or aff. in total) from the Bamchi Formation, Yeongwol, Korea. The conodont zones include the Streptognathodus bellus, S. isolatus, S. cristellaris, S. sigmoidalis, S. fusus and S. barskovi zones in ascending order, which can be correlated with the conodont zones spanning the uppermost Gzhelian to Asselian Age of the Permian globally. The fusuline zone is named the Rugosofusulina complicata–Pseudoschwagerina paraborealis zone. The co-occurrence of the conodont Streptognathodus isolatus (the Global Boundary Stratotype Section and Point index for the base of Permian) and Pseudoschwagerina (a Permian inflated fusuline) indicates that the Carboniferous–Permian boundary can be placed in the lower part of the Bamchi Formation in South Korea.

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 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.

New Chinese psocids from Eocene Fushun amber (Insecta: Psocodea)

Zhang, Q., Nel, A., Azar, D. & Wang, B. April 2016. New Chinese psocids from Eocene Fushun amber (Insecta: Psocodea). Alcheringa 40, xxx–xxx. ISSN 0311-5518

Two new Psocodea, Sinopsyllipsocus fushunensis gen. et sp. nov. and Eotriplocania sinica gen. et sp. nov., are described from Eocene amber of Fushun City, China. They are distinctly different from all known Psocodea from Fushun amber in their three-segmented tarsi. Sinopsyllipsocus fushunensis is the second unequivocal fossil of Psyllipsocidae. Eotriplocania sinica is the first Asiatic and oldest representative of the Neotropical family Ptiloneuridae, and reveals a formerly global distribution of the family. The discovery of these two families in Eocene Fushun amber suggests a rather warm palaeoclimate for the Fushun amber locality.

Dendroid multicellular thallophytes preserved in a Neoproterozoic black phosphorite in southern China

Du, W., Wang, X.L., Komiya, T., Zhao, R. & Wang, Y., April 2016. Dendroid multicellular thallophytes preserved in a Neoproterozoic black phosphorite in southern China. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

A new form of dendroid multicellular thallophyte is documented in the Ediacaran Doushantuo phosphorite at Weng’an, Guizhou Province, southern China. The dendroid thallophytes have variable forms, possibly owing to heteromorphic variation. Many lateral branches extend from the upper portions of the main axes; the lateral branches bear terminal vegetative vesicles, reproductive vesicles, monosporangium-like discoidal vesicles and urn-shaped pseudoparenchymatous structures. The vegetative vesicles give rise to clavate pseudoparenchymatous structures, characterized by differentiation of the thallus medulla/cortex, which might represent an early stage of thallus development. An oogamous conceptacle arising from one carpogonial vesicle forms a highly specialized goblet-shaped conceptacle. The discovery of the new dendroid multicellular thallophytes provides not only the first fossil-based evidence of the morphological complexity and tissue differentiation in the Precambrian organisms but also insights into the life cycle of the Precambrian red algae.

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.

Revision of the damsel-dragonfly family Campterophlebiidae (Odonata) from the Early Jurassic of England reveals a new genus and species

Kelly, R.S. & Nel, A., October 2017. Revision of the damsel-dragonfly family Campterophlebiidae (Odonata) from the Early Jurassic of England reveals a new genus and species. Alcheringa 42, 87–93. ISSN 0311-5518.

Historical fossil insect collections from England were re-examined and the taxa revised. Lateophlebia gen. nov. is erected for Liassophlebia anglicanopsis (Zeuner) in Campterophlebiidae. Petrophlebia anglicana Tillyard is confirmed in this family and Archithemis liassina (Strickland) is transferred to this family. Lastly, Archithemis brodiei (Geinitz), Archithemis Handlirsch, and Architemistidae Tillyard (reduced to this sole species) are transferred to the Heterophlebioidea.

New fossil damsel–dragonfly clarifies the phylogenetic position of the small Jurassic family Juraheterophlebiidae (Odonata: Epiproctophora)

HUANG D. & NEL A., June 2017. New fossil damsel -dragonfly clarifies the phylogenetic position of the small Jurassic family Juraheterophlebiidae (Odonata: Epiproctophora). Alcheringa, 41, 536–542.

A nearly complete specimen of Juraheterophlebia cancellosa sp. nov., the third species of the family Juraheterophlebiidae, is described from the Middle–Late Jurassic of China and shows the exact structure of its forewing discoidal space. As a consequence, this family is restored, separated from Erichschmidtiidae, and its diagnosis amended. It is transferred from Heterophlebioptera to Stenophlebioptera, the first clade being now only known from the Early Jurassic. Erichschmidtiidae includes the sole species Erichschmidtia nigrimontana, and this family is now considered of uncertain systematic position.

The long-ranging macroalga Grypania spiralis from the Ediacaran Doushantuo Formation,Guizhou, South China

Wang, Y., Wang, Y. & Du, W., February 2016. The long-ranging macroalga Grypania spiralis from the Ediacaran Doushantuo Formation, Guizhou, South China. Alcheringa 40, xxx–xxx. ISSN 0311-5518

Grypania spiralis (Walcott) Walter et al., a macroalga previously reported in pre-Ediacaran successions, has been collected, together with abundant macrofossils (i.e., the Wenghui biota), from black shales of the upper Doushantuo Formation (ca 593 to 551 Ma) in northeastern Guizhou, South China. Morphologically, G. spiralis represents a carbonaceous ribbon with a continuum of forms from coiled to nearly straight. Its helicoid main body might have been suspended in the water column for photosynthesis with one end anchored or nestled into soft sediments. Grypania possessed morphological stability, and its habit endowed great competitiveness for sunlight. Remarkably, it did not change significantly in size or morphology over more than 1200 Myrs.
