Three New Species

AbstractSystematic paleontology of three new species of Petalocrinidae (Crinoidea) are documented from the carbonate-dominated units of the Shihniulan and equivalent Leijiatun formations (Llandovery, Silurian) of the Baisha, Fengxiang, and Shuibatang sections in Guizhou (China). New taxa are from the Upper Yangtze Epicontinental Sea of the South China Block. The new taxa include Petalocrinus stenopetalus new species, Spirocrinus circularis new species, and S. dextrosus new species. They have a narrow spatial and temporal (Aeronian) distribution. Evolutionary patterns of the four genera of Petalocrinidae are outlined based on the specialized characters of the fused arm plates. Phylogenetic analysis was used to assess morphological relationships within the Petalocrinidae. Petalocrinus inferior represents the plesiomorphic condition for the group and nests as a sister group of P. stenopetalus n. sp. and the Spirocrinus species used in this analysis and the clade exclusively comprised of Sinopetalocrinus. The phylogenetic analysis suggests that Petalocrinus, as currently defined, might be a paraphyletic genus.

Patch Group

The genus Liolaemus is a group of lizards with more than 230 recognized species, which have been grouped in differentclades and subgroups. One of the monophyletic groups is the one of Liolaemus boulengeri or “the patch group”; this cladeitself is integrated by several monophyletic groups: the groups Liolaemus anomalus, Liolaemus wiegmanii, Liolaemusdarwinii and Liolaemus melanops. The latter group is constituted almost exclusively by Patagonian lizards, and it is ourfocal group. In the present work we describe three new species belonging to the Liolaemus melanops group. One of thenew taxon described, Liolaemus tromen sp. nov., is related to the Liolaemus fitzingerii clade, inhabits in the Center-Westof Neuquén Province, and was confused initially with Liolaemus hermannunezi, a mountain Chilean species. The secondspecies described, Liolaemus purul sp. nov., belongs to the Liolaemus telsen clade, inhabits in the center and north-westof Neuquén Province, and was confused first with Liolaemus boulengeri and then with Liolaemus loboi. While the thirdspecies, Liolaemus dumerili sp. nov., is basal of the L. goetschi group, inhabits in the center-south of Río Negro provinceand was considered as Liolaemus melanops. In addition, we present a phylogenetic analysis based in the morphology and we contribute with a dichotomic key for males of the Liolaemus melanops group.

Three New Species

Phylogenetic analysis was used to evaluate evolutionary relationships within the Cambrian suborder Olenellina Walcott, 1890; special emphasis was placed on those taxa outside of the Olenelloidea. Fifty-seven exoskeletal characters were coded for 24 taxa within the Olenellina and two outgroups referable to the “fallotaspidoid” grade. The Olenelloidea, along with the genusGabriellusFritz, 1992, are the sister group of the Judomioidea Repina, 1979. The “Nevadioidea” Hupé, 1953 are a paraphyletic grade group. Four new genera are recognized,Plesionevadia, Cambroinyoella, Callavalonia, andSdzuyomia, and three new species are described,Nevadia fritzi, Cirquella nelsoni, andCambroinyoella wallacei. Phylogenetic parsimony analysis is also used to make predictions about the ancestral morphology of the Olenellina. This morphology most resembles the morphology found inPlesionevadiaandPseudojudomiaEgorova in Goryanskii and Egorova, 1964.

New Distribution

The further collection and study of Chinese wolf spiders, family Lycosidae Sundevall, 1833, expand the known distribution of the subfamily Artoriinae Framenau, 2007 from Yunnan to Guangxi, Guizhou, and Sichuan Provinces of South China. Sinartoria gen. nov. is described to include two new species, S. damingshanensis sp. nov. (type species) and S. zhuangius sp. nov. In addition, a new Artoria species, A. hamata sp. nov. is described and new distribution records for A. ligulacea (Qu, Peng & Yin, 2009) and A. parvula Thorell, 1877 are provided. Within the Artoriinae, Sinartoria gen. nov. appears to be most similar to the South American Lobizon Piacentini & Grismado, 2009, but their relationship will remain contentious without a comprehensive phylogenetic analysis of artoriine genera.

Three New Species

Three novel fungal species, Talaromyces gwangjuensis, T. koreana, and T. teleomorpha were found in Korea during an investigation of fungi in freshwater. The new species are described here using morphological characters, a multi-gene phylogenetic analysis of the ITS, BenA, CaM, RPB2 regions, and extrolite data. Talaromyces gwangjuensis is characterized by restricted growth on CYA, YES, monoverticillate and biverticillate conidiophores, and globose smooth-walled conidia. Talaromyces koreana is characterized by fast growth on MEA, biverticillate conidiophores, or sometimes with additional branches and the production of acid on CREA. Talaromyces teleomorpha is characterized by producing creamish-white or yellow ascomata on OA and MEA, restricted growth on CREA, and no asexual morph observed in the culture. A phylogenetic analysis of the ITS, BenA, CaM, and RPB2 sequences showed that the three new taxa form distinct monophyletic clades. Detailed descriptions, illustrations, and phylogenetic trees are provided.

Three New Species

Two new genera and three new species of cave-adapted ground beetles belonging to the tribe Trechini are established and described: Wulongius qilingergen. nov. and sp. nov. from limestone cave Qiankou Dong (Chongqing: Wulong), Qianotrechus congcongaesp. nov. from cave Shigao Dong (Chongqing: Nanchuan), and Qianlongius zhouigen. nov. and sp. nov. from cave Qianlong Dong (Guizhou: Songtao). Wulongius qilingersp. nov. is a small aphaenopsian beetle with a thin and elongated body, while Qianlongius zhouisp. nov. is a semi-aphaenopsian with a stout body. Both new genera are not closely related to any genus of Trechini occurring in the South China Karst, and so their systematic positions remain unclear.

The Early Cambrian olenelline trilobites are a diverse clade and have been the subject of several phylogenetic analyses. Here, three new species of Bradyfallotaspis Fritz, 1972 (B. coriae, B. nicolascagei, and B. sekwiensis) and one new species of Nevadia Walcott, 1910 (N. saupeae) are described from the Sekwi Formation of the Mackenzie Mountains, Northwest Territories, Canada. In addition, new specimens potentially referable to Nevadia ovalis McMenamin, 1987 were recovered that may expand that species’ geographic range, which was thought to be restricted to Sonora, Mexico. The results of a phylogenetic analysis incorporating several olenelline taxa, including Judomia absita Fritz, 1973 from the Sekwi Formation, are also presented herein. This species has been assigned to various olenelline genera, including Judomia Lermontova, 1951 and Paranevadella Palmer & Repina, 1993. Phylogenetic analysis suggests this species is closely related to Judomia tera Lazarenko, 1960 from Siberia. This phylogenetic relationship provides further support for the hypothesis that a close biogeographic relationship existed between Laurentia and Siberia during the Cambrian.
