  ABSTRACT: The plant bug tribe Halticini (Heteroptera: Miridae) is revised. The genus Coridromius Signoret, 1862 is removed from the Halticini to form the new monogeneric tribe Coridromiini. A generic reclassification of the Halticini is given, comprising 25 genera: Acratheus Distant, 1910; Anapus Stål, 1858; Barbarosia Kiyak, 1995; Chorosomella Horváth, 1906; Compositocoris Schwartz, Schuh & Tatarnic, 2008; Dampierella Tatarnic, 2009; Dasyscytus Fieber, 1864; Dicyphopsis Poppius, 1914; Dimorphocoris Reuter, 1890; Ectmetopterus Reuter, 1906; Euryopicoris Reuter, 1875; Goodeniaphila Tatarnic, 2009; Halticus Hahn, 1833; Labops Burmeister, 1835; Microtechnites Berg, 1883; Myrmecophyes Fieber, 1870; Nanniella Reuter, 1904; Namaquacapsus Schuh, 1974; Orthocephalus Fieber, 1858; Pachytomella Costa, 1890; Piezocranum Horváth, 1877; Plagiotylus Scott, 1874; Schoenocoris Reuter, 1890; Scirtetellus Reuter, 1890, and Strongylocoris Blanchard, 1840. Microtechnites is reinstated from synonymy with Halticus, and Platyporus Reuter, 1890 is proposed as a new junior synonym of Anapus. The following new combinations are proposed for ten species formerly placed in Halticus: Ectmetopterus bicoloratus (Kulik, 1965), Ectmetopterus comitans (Josifov & Kerzhner, 1972), Ectmetopterus fuscous (Zou, 1985), Ectmetopterus maculipes (Zou, 1985), Ectmetopterus niger (Zou, 1985) and Microtechnites bractatus (Say, 1832), Microtechnites canus (Distant, 1893), Microtechnites chrysolepis (Kirkaldy, 1904), Microtechnites minutus (Reuter, 1885), and Microtechnites spegazzini (Berg, 1883). New combinations for two species formerly placed in Cafayatina Carvalho & Carpintero, 1986 are also proposed: Microtechnites altigena Carvalho & Carpintero, 1986 and Microtechnites inesalti (Carvalho & Carpintero, 1986). Revised diagnoses are provided for each genus. Redescriptions are provided for all but the most recently described genera. A key to the genera of Halticini is provided. Colour habitus photos of the type species for most genera are given. Scanning electron micrographs of salient characters and illustrations of male and female genitalia are provided for exemplars of each of the genera. Based on our phylogenetic analysis, we define a monophyletic Halticini, with the exclusion of Coridromius. Within the Halticini, Halticus is found to be sister to the remainder of the tribe.© 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 164, 558–658.

• Article: Systematic revision of Sabellariidae (Polychaeta) and their relationships with other polychaetes using morphological and DNA sequence data

  ABSTRACT: The affinities of honeycomb or sandcastle worms (Sabellariidae, Polychaeta) and other polychaetes are studied using morphological and DNA sequence data (18S rDNA, 28S rDNA, and EF-1 alpha). Maximum-parsimony analyses were performed including 20 terminals and 7155 aligned characters. The monophyly of Sabellariidae is confirmed and well supported and sister-group relationships with Spionida are suggested but only poorly supported. Phylogenetic relationships within Sabellariidae are also assessed for the first time, using morphological data. Maximum-parsimony analyses of 30 terminals and 31 characters were performed with and without weighting the less homoplasious characters. Implied weighting resolved polytomies recovered after non-weighting datasets and suggest that the established sabellariid subfamilies are not monophyletic and that the number of parathoracic segments is homoplastic. Instead, some opercular features and chaetal characters not often incorporated in descriptions are here shown to be phylogenetically informative and support some of the clades recovered. We provide a description of morphological features of sabellariid and previously related groups together with illustrations that will, we hope, be used as a baseline for further systematic and taxonomic studies in the group and as a framework for future molecular studies. Generic diagnoses and a description and a key to genera are provided.© 2012 The Linnean Society of London, Zoological Journal of the Linnean Society, 2012, 164, 245–284.

• Article: The skull of the Upper Cretaceous baurusuchid crocodile Baurusuchus albertoi Nascimento & Zaher 2010, and its phylogenetic affinities

  PAULO MIRANDA NASCIMENTO, HUSSAM ZAHER
  [show abstract] [hide abstract]
  ABSTRACT: We here describe the cranial remains of Baurusuchus albertoi Nascimento & Zaher, 2010, a Baurusuchidae from the Upper Cretaceous of Brazil that is known from a partially complete and articulated skeleton. The cranial anatomy provided important new information that allowed a more accurate analysis of its phylogenetic affinities. Phylogenetic results suggest that B. albertoi is the sister-group of a clade formed by Baurusuchus pachecoi and Baurusuchus salgadoensis. Characters that place B. albertoi within the family Baurusuchidae are: antorbital portion of the jugal more than two times higher than the infratemporal part; rod-shaped infratemporal bar of the jugal; dorsal process of the quadratojugal extensively contacting the postorbital; posterolateral process of squamosal totally deflected ventrally; cervical neural spines anteroposteriorly large; spool-shaped vertebral centra; cranial table as wide as ventral portion. Baurusuchus albertoi differs from the remaining two species of the genus by having a more excavated triangular depression of the jugal suborbital portion, an area that is also more ventrally developed; a vertical and lateromedially thin retroarticular process; and descending expansion of the lateral edge of the squamosal anteriorly concave.© 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163, S116–S131.

• Article: A new cretaceous notosuchian (Mesoeucrocodylia) with bizarre dentition from Brazil

  [show abstract] [hide abstract]
  ABSTRACT: A new species of Notosuchia, Labidiosuchus amicum gen. et sp. nov., is described based on an incomplete lower jaw (DGM 1480-R) from the Upper Cretaceous Marília Formation (Maastrichtian) recovered from a quarry near the Peirópolis municipality, Minas Gerais State, Southeastern Brazil. The mandibular symphysis is long, strong anterodorsally projected and ‘Y-shaped’. The bizarre dentition is formed by at least eight teeth placed in a symphyseal tooth battery, some located lateral to each other. The first pair is larger than all others and procumbent. Some teeth are obliquely implanted (anterolabially to posterolingually) and have sub circular to elliptical outline. At least the posterior teeth are single cuspidate with acute apex. Labidiosuchus amicum shows a rather bizarre dentition, increasing the taxonomic diversity and potential feeding strategies of notosuchian crocodylomorphs.© 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163, S109–S115.

• Article: Phylogenetic analysis, taxonomic revision, and dental ontogeny of the Cretaceous Zhelestidae (Mammalia: Eutheria)

  ABSTRACT: The eutherian, family-level clade Zhelestidae is consistently although weakly supported in five phylogenetic analyses that we performed on all Cretaceous eutherians. Additionally in the fifth analysis, which included some placentals, Zhelestidae is placed as a stem eutherian clade rather than grouping within the crown clade Placentalia as argued in some previous studies but not others. The subfamily Zhelestinae, Dzharakuduk (Turonian –?Coniacian ages), Kyzylkum Desert, Uzbekistan includes Zhelestes temirkayzk, Aspanlestes aptap, Parazhelestes mynbulakensis (= Sorlestes budan), Parazhelestes robustus, Eoungulatum kudukensis. Additional taxa for the time being recognized as Zhelestidae incertae sedis are: Sheikhdzheilia rezvyii (Cenomanian, Uzbekistan), Borisodon kara gen. nov. (=‘Sorlestes’kara) (Turonian, Kazakhstan), Lainodon orueetxebarriai (Campanian or Maastrichtian, Spain), Labes quintanillensis (Maastrictian, Spain), Labes garimondi (Campanian, France), Gallolestes pachymandibularis (Campanian, Mexico), Gallolestes agujaensis (Campanian, USA), and Avitotherium utahensis (Campanian, USA). Eozhelestes mangit (Cenomanian, Uzbekistan) is a questionable zhelestid (?Zhelestidae), possibly stem to Zhelestidae. Paranyctoides (Asia and North America) is often linked to Zhelestidae. Alostera, previously referred to Zhelestidae, is a eutherian of unknown affinities. Associated skull fragments permitted the first reconstruction of a zhelestid (Aspanlestes) skull. Abundant dentulous and edentulous dentaries allowed examination of dental replacement from the canine posteriorly in Dzharakuduk zhelestids as follows: [dc, p1, dp2, p3, dp4, dp5]-> m1-> p2-> c, p4, m2-> p5-> m3.

• Article: The concept of genus within the family Phytoseiidae (Acari: Parasitiformes): historical review and phylogenetic analyses of the genus Neoseiulus Hughes

  ABSTRACT: Systematic studies on the family Phytoseiidae were first conducted at the beginning of the 20th century but increased greatly after the Second World War. Various classifications have been proposed based on different characters such as: dorsal, ventral, and leg chaetotaxy; the shape of ventrianal and sternal shields; the shape of the insemination apparatus (spermatheca) and spermatodactylus; the number of teeth on the movable digit of chelicera; and dorsal and ventral adenotaxy. The genus concepts developed over the last five decades can be divided into two main categories or hypotheses. The first, supported mainly by Chant and McMurtry, focuses on dorsal and ventral chaetotaxy, and the genera so defined usually include a great number of species. The second category, proposed by Athias-Henriot, considers the shape of the insemination apparatus as the key character, and the genera so defined usually include a limited number of species. From a diagnostic point of view, both classifications have a valid structure, but the question investigated herein was: which of the two classifications or hypotheses fits phylogenetic evolution? To answer this, we conducted molecular phylogenetic analyses (using the genes ITS and 12S rRNA) on the genus Neoseiulus, which has been subjected to classification based on the two main genus concepts. The results showed that the first hypothesis (Chant and McMurtry) leads to polyphyly of the genus Neoseiulus, while the second (Athias-Henriot) leads to paraphyly of the genus. The results show that acarologists who first decided that the insemination apparatus was of evolutive importance could be correct as the shape of the insemination apparatus seems to better fit evolutive clades than dorsal and ventral chaetotaxy. The morphology of this organ, however, must be more accurately studied to better define homologies. The present paper investigates the two main hypotheses proposed until now for classification of Phytoseiidae and thereby opens the way for improved classification.
