New fossil Ochteridae (Hemiptera: Heteroptera: Ochteroidea) from the Upper Mesozoic of north‐eastern China,with phylogeny of the family

Specimens of the velvety shore bugs (Hemiptera: Ochtheridae) occur in the Early Cretaceous Yixian Formation in north‐eastern China. We describe two new genera and three new species –Pristinochterus ovatus Yao, Zhang & Ren sp. nov., Floricaudus multilocellus Yao, Ren & Shih gen.n. et sp.n. and Angulochterus quatrimaculatus Yao, Zhang & Ren gen.n. et sp.n. – from this deposit. A cladistic analysis based on a combination of fossil and extant taxa, and their morphological characters, clarifies the phylogenetic status of the new fossils and allows the reconstruction of relationships within the family Ochteridae. Two main clades within Ochteridae are recognized from the cladistic analysis: Pristinochterus Yao Cai & Ren and Floricaudus Yao, Ren & Shih gen.n. form a monophyletic lineage; and Angulochterus Yao, Zhang & Ren gen.n. emerges as a sister group to all extant velvety shore bugs. A key to all fossil and extant genera of Ochteridae is provided.     

New Paleocene large cassiduline foraminifera (Cassidinidae fam. nov., Miscellanacea) from Egypt and its phylogeny

Larger foraminifera of the Late Paleocene–Early Eocene lower slope to toe-of-slope deposits of the southern Galala, Egypt, are described. Sulcocassidina nakkadyi n. gen. et sp. (base) and Vacuolicassidella dakhlensis n. gen. et sp. (top) represent a phylogenetic line related to the family Cassidinidae (new family), superfamily Miscellanacea (new superfamily) in the latest Paleocene (shallow benthic zone 4) of the southern Galala, Egypt. In addition, Oscucassidella cassis n. gen. et sp., Pellatispiroides youssefi n. gen. et sp. and Chordcassidella ainshamsiana n. gen. et sp. are described and illustrated. Genus: Pomerolina n. gen. (Type species: Alveolina meandrina Carter, 1861, is newly erected and it belongs to Cassidinidae. In this family, the chambers are initially arranged streptospirally, whereas in later stages they are planispirally enrolled. Lateral chamberlets (retral process) are separated from the laminae by a passage and a marginal crest is added during growth.     

Revision of basal calanoid copepod families,with a description of a new species and genus of Pseudocyclopidae

A newly discovered plesiomorphic genus and species of calanoid copepod ( P inkertonius ambiguus gen. et sp. nov. ) taken with an epibenthic sledge from the flanks of the Chatham Rise, east of New Zealand, at a depth of about 900 m, could not be assigned to any known genus or family based on available diagnoses. A morphology‐based cladistic analysis of all genera previously placed in the Epacteriscidae, Pseudocyclopidae, Ridgewayiidae, Boholinidae, and the new taxon is presented. The Pseudocyclopidae and Epacteriscidae are confirmed as monophyletic families, and the family names Ridgewayiidae and Boholinidae become synonyms of Pseudocyclopidae. There are no grounds upon which more than a single basal superfamily, the Pseudocyclopoidea, can be recognized. The superfamily Pseudocyclopoidea, and families Pseudocyclopidae, Epacteriscidae, and the new genus are diagnosed. P inkertonius ambiguus gen. et sp. nov. is placed within the Pseudocyclopidae. Genetic data adds to the definition of the new taxon and confirms the basal position of the Pseudocyclopoidea in a revised Calanoida phylogeny. This phylogeny contributes to an improved resolution of the relationships among the Centropagoidea, Megacalanoidea, Bathypontioidea, Eucalanoidea, and Clausocalanoidea, as well as providing testable hypotheses for future work. © 2014 The Linnean Society of London

Phylogeny and classification of Corylophidae (Coleoptera: Cucujoidea) with descriptions of new genera and larvae

Abstract Phylogenetic relationships within the family Corylophidae were investigated. Twenty ingroup taxa and six outgroups were included in a cladistic analysis, based on 48 characters derived from adult and larval morphology. Phylogenetic analysis confirms that Corylophidae are monophyletic within the superfamily Cucujoidea and may be subdivided into two subfamilies: the Australian Periptycinae and the cosmopolitan Corylophinae containing 10 tribes: Foadiini trib.n. , Cleidostethini, Aenigmaticini, Parmulini, Sericoderini, Peltinodini, Orthoperini, Corylophini, Teplinini and Rypobiini. All currently recognized family‐group taxa are thoroughly diagnosed, and keys to their identification based on adults and larvae are provided. Two new genera and three species are described: Weirus gen.n ., containing only W. tozer sp . n . (Australia: Queensland), and Stanus gen.n. , with the two species S. bowesteadi sp.n . (New Zealand) and S. tasmanicus sp.n. (Tasmania). The larvae of Pakalukodes bimaculatus?lipiński et al. from Queensland and of Stanus bowesteadi sp.n. from New Zealand are described and illustrated for the first time.     

A new Early Cretaceous snakefly (Raphidioptera: Mesoraphidiidae) from El Soplao amber (Spain

A virtually complete specimen of the family Mesoraphidiidae (Insecta: Raphidioptera) is described as Cantabroraphidia marcanoi n. gen., n. sp. It was found in early Albian amber from a new deposit named El Soplao within the Las Peñosas Fm. in northwestern Cantabria (Spain). It has been compared to all adult fossils placed in the Mesozoic family Mesoraphidiidae. Some taxonomical comments are provided, and we propose to restore the genus Yanoraphidia Ren 1995 and the combination Yanoraphidia gaoi Ren 1995 stat. rest., provisionally retained in the family Mesoraphidiidae.     

New fossils from China elucidating the phylogeny of Praesiricidae (Insecta: Hymenoptera)

A new subfamily of Praesiricidae (Pamphilioidea), Decorisiricinae subfam.n. , is erected based on three new genera: Decorisiricius gen.n. , Limbisiricius gen.n. and Brevisiricius gen.n. Two new species – Decorisiricius patulus gen. et sp.n. and D. longus sp.n. – from the Lower Cretaceous Yixian Formation and three species –Limbisiricius aequalis gen. et sp.n. , Limbisiricius complanatus sp.n. and Brevisiricius partialis gen. et sp.n. – from the Middle Jurassic Jiulongshan Formation, are described. Based on these well‐preserved new fossil specimens and previously published data, the nonmonophyly of Praesiricidae is confirmed and the phylogenetic relationships of species of Praesiricidae are analysed for the first time. Two main clades within Praesiricidae are recognized from the cladistic analysis: Decorisiricinae subfam.n. forms a monophyletic lineage, with the remaining members of Praesiricidae plus Megalodontes (Megalodontesidae) forming its sister group. The two subfamilies Archoxyelydinae and Praesiricinae are discarded with no strong supported synapomorphic characters based on phylogenetic research. A key to all genera of Praesiricidae is provided.

Protalveolate phylogeny and systematics and the origins of Sporozoa and dinoflagellates (phylum Myzozoa nom. nov.)

The protozoan infrakingdom Alveolata comprises the phyla Ciliophora and Miozoa. The name Myzozoa—sucking life—is introduced here to replace Miozoa (protalveolates, dinoflagellates, Sporozoa, apicomonads) as both subphyla (Dinozoa, Apicomplexa) are commonly or ancestrally myzocytotic feeders. We studied ultrastructurally two contrasting myzocytotic flagellates: Colpodella tetrahymenae sp. n. (predatory on Tetrahymena), with an inner membrane complex like Sporozoa, and Voromonas (=Colpodella) pontica gen. et comb. nov., with discrete cortical alveoli like Dinozoa; we also sequenced 18S rDNA of both of these flagellates and of two highly divergent isolates of Oxyrrhis. Phylogenetic analysis shows early divergence between Colpodella, Voromonas and Alphamonas edax and supports the independent origin of dinoflagellates, Perkinsea and Apicomplexa (Sporozoa, Apicomonadea) from myzocytotic protalveolate flagellates. Oxyrrhis is probably a highly modified dinoflagellate, not a protalveolate with primitive chromatin and ciliary organization. The rapid basal radiation of Myzozoa is poorly resolved; the predatory colpodellids sensu stricto are probably sisters of Sporozoa. We discuss early cellular diversification of Myzozoa (=Miozoa) and revise its classification, establishing a new class Myzomonadea for Voromonas, Alphamonas and Chilovora (=Bodo) perforans gen. et comb. nov., three new peridinean subclasses (Oxyrrhia, Gonaulacoidia, Suessioidia), and five new orders: Acrocoelida for Acrocoelus; Voromonadida for Voromonas and Alphamonas; Chilovorida for Chilovora; Rastromonadida for Rastromonas and Parvilucifera; and Algovorida for Algovora, a new genus for Colpodella turpis and Colpodella pugnax sensu Simpson and Patterson. We suggest that the flattened inner membrane complex of Apicomplexa evolved in association with trichocyst loss by fusion of already flattened myzomonad cortical alveoli as an adaptation for actomyosin-based host penetration and gliding motility.     

Taxonomic status of the species of the green algal genusNeochloris

Komárek has recently reviewed the various species assigned to the green algal genusNeochloris Starr (Chlorococcales, Chlorococcaceae) and removed those with uninucleate vegetative cells to a new genus,Ettlia. Watanabe & Floyd, unaware ofKomárek's work, also reviewed the species ofNeochloris and distributed them among three genera—Neochloris, Chlorococcopsis gen. nov., andParietochloris gen. nov.—on the basis of details of the covering of the zoospore and the arrangement of the basal bodies of the flagellar apparatus. This paper reconciles these two treatments and makes additional recommendations at the ranks of genus, family, order, and class.     

Phylogeny of Evanioidea (Hymenoptera,Apocrita), with descriptions of new Mesozoic species from China and Myanmar

The phylogeny of the superfamily Evanioidea is presented using morphology and DNA sequence data of selected extant and fossil genera by employing two phylogenetic methods, maximum parsimony and Bayesian inference. Based on our new results, the monophyly of Evanioidea is corroborated. Evanioidea, Anomopterellidae, Othniodellithidae, Andreneliidae and Evaniidae are monophyletic families, while Praeaulacidae, Aulacidae, Baissidae and Gasteruptiidae are paraphyletic families. In addition, four new genera (Sinuevania gen.n. , Curtevania gen.n. , Exilaulacus gen.n. , Heterobaissa gen.n. ) with five new species (Sinuevania mira sp.n. , Curtevania enervia sp.n. , Exilaulacus loculatus sp.n. , Exilaulacus latus sp.n. , Heterobaissa apetiola sp.n. ), and five additionally new species (Newjersevania longa sp.n. , Newjersevania brevis sp.n. , Cretevania tenuis sp.n. , Cretevania venae sp.n. , Praeaulacus rectus sp.n. ) and one new combination [Cretevania mitis (Li, Shih & Ren, 2014a) comb.n. ] are described based on well‐preserved fossils from the Middle Jurassic Jiulongshan Formation in Inner Mongolia, China, the Early Cretaceous Yixian Formation in Liaoning, and mid‐Cretaceous amber from Myanmar. This study documents the diversification of one major lineage of the mid‐Mesozoic parasitoid revolution that dramatically changed food‐web relationships in terrestrial ecosystems.

Paramesopsocidae,a new Mesozoic psocid family (Insecta: Psocodea “Psocoptera”: Psocomorpha)

Paramesopsocus lu n. gen., n. sp. and Paramesopsocus adibi n. sp. are respectively described from the Early Cretaceous amber of Lebanon and from the Late Jurassic limestone of Karatau (Kazakhstan). They are placed within the suborder Psocomorpha, and in the Mesozoic extinct family Paramesopsocidae n. fam. A cladistic phylogeny for Psocomorpha is given including our fossil taxa. The discovery of these new taxa demonstrates the necessity of a deep cladistic redefinition of the currently admitted major subdivisions of this suborder.     

New fossil mantidflies (Insecta: Neuroptera: Mantispidae) from the Mesozoic of north‐eastern China

Abstract:  Three new genera and four new species of the extinct mantidfly subfamily Mesomantispinae (Insecta: Neuroptera: Mantispidae) are described from the Lower Cretaceous Yixian Formation of Liaoning and the Middle Jurassic Jiulongshan Formation of Inner Mongolia: Archaeodrepanicus nuddsi gen. et sp. nov., A. acutus gen. et sp. nov., Sinomesomantispa microdentata gen. et sp. nov., (Yixian Formation) and Clavifemora rotundata gen. et sp. nov. (Jiulongshan Formation). The specimens described herein represent the first Mesozoic mantidfly compression fossils to have body parts preserved, including the specialized raptorial forelegs articulated to the prothorax anteriorly, an autapomorphy of the family. These new taxa further confirm the placement of the subfamily Mesomantispinae within the family Mantispidae; however, the monophyly of Mesomantispinae has not been confirmed, and it is likely that it will prove to be paraphyletic.     

The oldest known clerid fossils from the Middle Jurassic of China,with a review of Cleridae systematics (Coleoptera)

Three fossil beetles recorded from Inner Mongolia, China (Callovian, Middle Jurassic, approximately 165 Ma) are assigned to Cleridae and constitute the earliest known representatives of this family. Two of the fossils are described as Protoclerus korynetoides gen. et sp.n. and the third as Wangweiella calloviana gen. et sp.n. Ninety‐six morphological characters of the larvae and adults of 17 extant clerid representatives and seven cleroid families as outgroups were analysed under maximum parsimony with, and without, fossil species included in the matrix. The results indicate that Protoclerus gen.n. is a separate lineage within the family, whereas Wangweiella gen.n. is sister to the rest of Epiclininae. The resulting trees are compared with the most recent morphological and molecular phylogenies of Cleridae. The trees presented appear congruent with the latest molecular phylogenies. The evolution of Cleridae, as well as their biogeography and systematics, are briefly reviewed. A complete list of clerid fossil species described to date is provided.

Feather mites (Astigmata: Psoroptidia) parasitising the rock ptarmigan <Emphasis Type="Italic">Lagopus muta</Emphasis> (Montin) (Aves: Galliformes) in Iceland

Four new species of feather mites are described from the Icelandic rock ptarmigan Lagopus muta islandorum (Faber) in Iceland. These are Metamicrolichus islandicus n. sp., Myialges borealis n. sp. (Epidermoptidae), Strelkoviacarus holoaspis n. sp. (Analgidae) and Tetraolichus lagopi n. sp. (Pterolichidae). This is the first report on feather mites associated with the Icelandic rock ptarmigan. Brief comments on the systematics and biology of corresponding feather mite genera are given. For two species, originally described in Pterolichus Robin, 1868 (Pterolichidae), new combinations are proposed, i.e. Tetraolichus gaudi (Černy, 1971) n. comb. and T. microdiscus (Trouessart, 1887) n. comb.
