AbstractA single specimen of a new species of the synziphosurine Kasibelinurus Pickett, 1993 is described from the Lower Devonian (Lochkovian) Xiaxishancun Formation of Yunnan Province, China. The new species, K. yueya sp. nov., extends the geographic extent of the family Kasibelinuridae from the Australian palaeocontinent to the South China palaeocontinent, and the stratigraphic range back some 50 Ma from Late to Early Devonian.

Fossil isopod crustaceans in the suborder Phreatoicidea have a known stratigraphic range from the Carboniferous to the Jurassic. Until now, all Mesozoic records of this group were thought to occur in fresh water habitats. A new phreatoicidean isopod fossil of the Triassic Luoping marine fauna, Yunnan Province, China, is described. The new species, based on several exceptionally complete specimens, is assigned to the genusProtamphisopusNicholls and the family Amphisopidae Nicholls. This Chinese record is the first report of a Mesozoic-age phreatoicidean isopod outside of Gondwanan terranes, requiring a revision of known biogeographic patterns of the Phreatoicidea. Whether this record is from a marine habitat or is the result of a secondary deposition is not certain.SottyellaRacheboef, Schram and Vidal from the Carboniferous (Stephanian) Lagerstätte of Montceaules-Mines that was assigned to this suborder may be a decapod. Therefore, it has no relationship to this new species.

Two new cirroidean gastropod genera, Alaskiella (family Porcelliidae) and Alaskacirrus (family Cirridae), from the Emsian (late Early Devonian) of west-central Alaska (Medfra B-4 quadrangle) are described. The shell of Alaskiella medfraensis new genus and species exhibits inclined heterostrophic coiling. This shell character is known among other members of the subclass Archaeogastropoda, but is recorded for the first time within members of the superfamily Cirroidea. Inclined heterostrophic coiling of the shell was probably developed independently in several different groups of the subclass Archaeogastropoda. The new genus Alaskacirrus, represented by Alaskacirrus bandeli new species, is the oldest and only known Paleozoic member of the family Cirridae. This suggests that the family Cirridae was separated from the family Porcelliidae since at least Early Devonian time and that it most probably developed from the subfamily Agnesiinae of the family Porcelliidae. Thus, the stratigraphic range of the family Cirridae is at least from Lower Devonian to Cretaceous, an interval of about 350 million years.

Burrowing Mayfly

A new species of sand-burrowing mayfly (Ephemeroptera: Behningiidae), Behningia nujiangensis Zhou & Bisset, is described based on more than 50 nymphs collected from the Nujiang River in Yunnan Province, P.R. China. This is the first species of the family Behningiidae discovered in China. It is also the second species of genus Behningia, and the third species of the family Behningiidae collected from the Oriental biogeographic region. The shapes of the labrum and the labium in B. nujiangensis are markedly different from those found in other species of Behningia. Differences in the mandibles, the galea-lacina of maxillae, and both the prothoracic and metathoracic legs differentiate B. nujiangensis from both B. baei and B. ulmeri. The biology of and conservation challenges for B. nujiangensis are also briefly discussed.

A New Species

Polychaetes of the family Capitellidae are poorly studied in Chinese waters. Amongst the known capitellid genera in China, Leiochrides Augener, 1914 is an unusual genus encountered in marine surveys. In this study, a Leiochrides specimen was obtained during a survey conducted in the Beibu Gulf, northern South China Sea and described herein as a new species Leiochrides guangxiensis sp. nov. The new species differs from its congeners by having uniramous chaetiger 1, chaetigers 11–12 with notopodial capillaries and neuropodial hooks, abdominal hooks with seven teeth above the main fang in three rows, pygidium with four anal cirri, and branchial fascicles with up to 17 filaments. The taxonomic status of the monospecific genus Pseudoleiocapitella Harmelin, 1964 and Leiochrides norvegicus Fauchald, 1972 are discussed.

Field work has greatly increased the number of well-dated papiliophyllid corals available from Nevada. The established range of the family is expanded from Pragian and lower Emsian to Pragian and almost the entire Emsian. Ranges of species are calibrated against Johnson faunal intervals and a revised Pragian and lowermost Emsian conodont zonation proposed by Murphy for Nevada. Study of all reposited material has led to some revision of every member of the family. Eurekaphyllum, previously imperfectly known from a single specimen of vague stratigraphic origin, is shown to be a useful upper Emsian index. Nine reported occurrences of the family in Europe and Asia are re-examined and, except for a possible occurrence on Novaya Zemlya, all are rejected. The three named genera of the family are apparently endemic to the southwestern North American craton. Papiliophyllum elegantulum asymmetricum new subspecies, P. murphyi new species and Eurekaphyllum vescum new species are described by Pedder.

A New Species

A new species of terrestrial ascomycetes belonging to the genus Lonicericola (Pleosporales, Dothideomycetes) found on dead branches of Caprifolioideae sp. in Yunnan Province, China is described and illustrated. A new classification is proposed to accommodate the new taxon based on the interpreted results from multigenic phylogenetic inference and micro morphological comparisons. The analysis of a combined SSU, LSU, ITS rDNA and tef1 dataset significantly supports both the shared monophyletic origin of Lonicericola in Parabambusicolaceae as well as L. fuyuanensis as a distinct new species. Comparisons of the distinct morphology of the new species L. fuyuanensis with the type species of the genus, L. hyaloseptispora, and other genera of the family Parabambusicolaceae are made.

A new genus Arquatopotamon gen. n. of the family Potamidae Ortmann, 1896, is established and a new species, Arquatopotamon jizushanense sp. n. from Yunnan Province, China is described. The new genus is established based on the distinctive distal part of the male first gonopod, with arched-shaped subterminal and terminal segments (in mesioventral view) and female gonopores (vulvae) on thoracic sternites 5/6 and a combination of characters including the carapace and male telson, while it is similar to the five known genera in Yunnan Province and adjacent area, Tenuipotamon Dai, 1990, Pararanguna Dai & Chen, 1985, Trichopotamon Dai & Chen, 1985, Potamiscus Alcock, 1909 and Aparapotamon Dai & Chen, 1985, in having a third maxilliped exopod without a flagellum. Present molecular data based on a barcoding marker of 16S rDNA provide strong support for the genus as being new.

Spore Diversity

ABSTRACTThe Lower Devonian Posongchong Formation (Wenshan, Yunnan Province, southwestern China) consists of a series of continental deposits with an outstanding plant megafossil diversity. More than 20 years ago, this formation was interpreted as ‘Siegenian' (∼Pragian) in age based on palynology. However, such interpretation needs further evidence because of the known differences between the dispersed spore assemblages from South China and Euramerica/northwestern Gondwana. Here, we present new dispersed spore assemblages recently recovered from the Posongchong Formation. The isolated spore diversity is highly diverse, with 18 genera and 32 species. The recognised taxa include, among others, Ambitisporites avitus, Aneurospora conica, Aneurospora posongchongensis sp. nov., Aneurospora xujiachongensis, Apiculiretusispora plicata, Archaeozonotriletes chulus, Concentricosisporites agradabilis, Dibolisporites echinaceus, Emphanisporites rotatus, Gneudnaspora divellomedia, Latosporites ovalis, Retusotriletes triangulatus, Tetrahedraletes medinensis and Verrucosporites polygonalis, with Aneurospora and Retusotriletes being the most abundant forms. The known Posongchong palynoflora (previous spore data included) suggests that the Posongchong Formation assemblages can be correlated with the Pragian interval of the polygonalis–wetteldorfensis Oppel Zone (PoW). This age determination is supported by the presence of index species of PoW, such as Verrucosporites polygonalis, Dictyotriletes subgranifer and Camarozonotriletes parvus (sensu Steemans, 1989), the latter being known only from the Pragian of Belgium and Germany. Recent advances in the study of the marine faunas in the overlying sequences also indicate a Pragian age for the Posongchong Formation. This new investigation of the Posongchong palynoflora highlights differences of abundance at species level between the Gondwanan–Laurussian floras during the Early Devonian.
