No full text31 pages : illustrations (some color), color maps ; 26 cm. Part of the Oonopidae PBI project. (Introduction)Four new species of oonopid spiders are described from Madagascar, divided between the genera Silhouettella and Noideattella: S. perismontes, sp. nov., S. perisalma, sp. nov., N. omby, sp. nov., and N. sylvnata, sp. nov. A new diagnosis for Silhouettella is provided, its type species, S. curieusei, from the Seychelles is redescribed, and its morphology thoroughly documented with digital images.
New Indian banyan plant bug.
No full text15 pages : illustrations (some color) ; 26 cm.A new genus and new species of the plant bug, Chimairacoris lakshmiae Yasunaga, Schuh, and Cassis are described from Bangalore, India. This morphologically and ecologically specialized mirid belongs to the subfamily Phylinae on the basis of genitalic structures and is currently considered best placed in the subtribe Oncotylina of the tribe Phylini. Its morphological convergence with termatophyline mirids and placement within the Phylinae are discussed. It is associated with psyllid leaf galls on Indian banyan, Ficus benghalensis. The gall-producing psyllid, Trioza sp., and a mealybug, Phenacoccus parvus, are confirmed as prey of this unique mirid. A similar phenomenon observed in some Montandoniola spp. (Anthocoridae) and Fingulus species (Miridae: Deraeocorinae), which are associated with thrips species of the genus Gynaikothrips (Thysanoptera: Tubulifera) on Ficus microcarpa, is also documented
New notoungulates from the early Oligocene.
No full text24 pages : illustrations ; 26 cm.Here we describe two new notoungulate taxa from early Oligocene deposits of the Abanico Formation in the eastern Tinguiririca valley of the Andes of central Chile, including a notostylopid (gen. et sp. nov.) and three basal toxodontians, cf. Homalodotheriidae, one of which is formally named a new species. The valley's eponymous fossil mammal fauna became the basis for recognizing a new South American Land Mammal "Age" intervening between the Mustersan and Deseadan of the classical SALMA sequence, the Tinguirirican. As a temporal intermediate between the bracketing SALMAs (Deseadan and Mustersan), the Tinguirirican is characterized by a unique cooccurrence of taxa otherwise known either from demonstrably younger or more ancient deposits, as well as some taxa with temporal ranges restricted to this SALMA. In this regard, two of the notoungulates described here make their last known stratigraphic appearances in the Tinguiririca Fauna, Chilestylops davidsoni (gen. et sp. nov.), the youngest notostylopid known, and Periphragnis vicentei (sp. nov.), an early diverging toxodontian, the youngest representative of the genus. A second species of Periphragnis from the Tinguiririca valley is provisionally described as Periphragnis, sp. nov., but is not formally named due to its currently poor representation. A specimen referred to Trigonolophodon sp. cf. T. elegans also is described. This taxon is noteworthy for also being reported from Santiago Roth's long perplexing fauna from Cañadón Blanco, now considered Tinguirirican in age. A phylogenetic analysis of notostylopids identifies Chilestylops as closely related to Boreastylops lumbrerensis from northern Argentina
Molecular and morphometric phylogenetics of Dryinidae and Bethylidae (Hymenoptera, Chrysidoidea)
No full textix, 166 pages : illustrations (chiefly color)Aculeata (Hymenoptera) is largely known for its bees, ants, and social wasps, from which most people would immediately recognize honey bees and paper wasps. However, sister to the clade of Apoidea and Vespoidea is the much smaller, and infinitely more enigmatic Chrysidoidea, which contains seven extant families that are relatively understudied. Unlike the other superfamilies, Chrysidoidea is exclusively parasitic -- although this behavior ranges from ectoparasitoidism to endoparasitoidism to cleptoparasitism (targeting solitary wasps and bees), as seen in Chrysididae (the cuckoo wasps). Dryinidae, which contains about 1700 species worldwide in 16 subfamilies, are parasitoids of Auchenorrhyncha (leafhoppers, planthoppers, and their allies) and are known to attack major rice and fruit crop pests. In Chapters II and III, the relationships within the family were investigated at the subfamily level. In Chapter II, a phylogeny reconstructed from 18S, 28S, Cytochrome Oxidase I (COI) and Cytochrome b (CytB) resulted in the resurrection of Thaumatodryinus to Thaumatodryininae to preserve the monophyly of Dryininae. Chapter III examined the utility of landmark analysis in parsimony using the methods implemented by Catalano et al. (2010) and subsequent publications. The trees constructed from the landmark analyses were incongruent with the combined molecular and morphological phylogeny, but landmark analyses could be utilized effectively to reconstruct species-level phylogenies for Dryinus and Gonatopus, both of which were found as nonmonophyletic in Chapters II and III. Chapters IV and V focused on Epyris, the largest genus within the subfamily Epyrinae, and Bethylidae as a whole. Epyris has long been suspected of being a taxonomic wastebasket, but the molecular phylogeny reconstructed from 16S, 18S, 28S, COI, and CytB is the first phylogeny to sample the worldwide breadth of its species diversity. Epyris was shown to be nonmonophyletic, although the type specimen, Epyris niger Westwood, was recovered in a clade with a distinct synapomorphy of large, nearly touching, scutellar pits. In Chapter V, five new species from Epyris sensu stricto were described from Western Australia and Queensland, and a key was provided to the known female Epyris of Australia.Richard Gilder Graduate School at the American Museum of Natural History
Scale insects in amber with phylogeny for fossil Coccoidea.
Get PDF80 pages : illustrations (some color) ; 26 cm.Coccoids are abundant and diverse in most amber deposits around the world, but largely as macropterous males. Based on a study of male coccoids in Lebanese amber (early Cretaceous), Burmese amber (Albian-Cenomanian), Cambay amber from western India (early Eocene), and Baltic amber (mid-Eocene), 16 new species, 11 new genera, and three new families are added to the coccoid fossil record: Apticoccidae, n. fam., based on Apticoccus Koteja and Azar, and including two new species A. fortis, n. sp., and A. longitenuis, n. sp.; the monotypic family Hodgsonicoccidae, n. fam., including Hodgsonicoccus patefactus, n. gen., n. sp.; Kozariidae, n. fam., including Kozarius achronus, n. gen., n. sp., and K. perpetuus, n. sp.; the first occurrence of a Coccidae in Burmese amber, Rosahendersonia prisca, n. gen., n. sp.; the first fossil record of a Margarodidae sensu stricto, Heteromargarodes hukamsinghi, n. sp.; a peculiar Diaspididae in Indian amber, Normarkicoccus cambayae, n. gen., n. sp.; a Pityococcidae from Baltic amber, Pityococcus moniliformalis, n. sp., two Pseudococcidae in Lebanese and Burmese ambers, Williamsicoccus megalops, n. gen., n. sp., and Gilderius eukrinops, n. gen., n. sp.; an Early Cretaceous eitschatidae, Pseudoweitschatus audebertis, n. gen., n. sp.; four genera considered incertae sedis, Alacrena peculiaris, n. gen., n. sp., Magnilens glaesaria, n. gen., n. sp., and Pedicellicoccus marginatus, n. gen., n. sp., and Xiphos vani, n. gen., n. sp. Interpretation of fossil coccoids is supported by a parsimony phylogenetic analysis based on 174 morphological characters (both adult males and females) and 112 taxa (69 Recent and 43 extinct)

Review of bopyrids parasitic on caridean shrimps.
No full text85 pages : illustrations ; 26 cm.A review of 37 bopyrid isopods known to infest 43 species of caridean shrimps in China is presented, based on literature records and new material. Synonymies are provided for all species, with descriptions and detailed illustrations given for species represented by material examined herein. Bopyrids recorded as new species or new Chinese records belong to the subfamilies Argeiinae (2 or 3 species, depending on the identity of Argeia sp.: Argeia pugettensis Dana, 1852, Argeia sp., Stegoalpheon kempi Chopra, 1923), Pseudioninae (2 species: Paranikione sibogae, n. gen. n. sp., and Paranikione distorta, n. sp.), Bopyrinae (13 species: Bathygyge grandis Hansen, 1897, Bopyrella articulata, n. sp., Bopyrinella parameces, n. sp., Bopyrione multifeminae, n. sp., Bopyroides hippolytes (Kröyer, 1838), Bopyroides shiinoi Rybakov and Andeev, 1991, Parabopyrella cuspidata, n. sp., Parabopyrella distincta (Nierstrasz and Brender à Brandis, 1923), Parabopyrella elongata (Shiino, 1949), Parabopyrella hodgarti (Chopra, 1923), Parabopyrella perplexa Markham, 1990, Parabopyrella symmetros, n. sp., and Septembopyrina tozeumaophila, n. gen., n. sp.), and Hemiarthrinae (2 species: Eophrixus caudatus, n. sp., and Sigyn branchialis, n. gen, n. sp.), collected from the South China Sea (7 species), East China Sea (3 species), Yellow Sea (4 species), and East and South China seas (2 species). Three new genera and 10 new species are described, with an additional four species newly recorded from Chinese waters. The genus Argeia is reviewed and a new genus is erected for Argeia lowisi Chopra, 1923, and Argeia nierstraszi Shiino, 1958. Capitetragonia Pearse, 1953, is recognized as the senior synonym of Probopyria Markham, 1985. The genus Parabopyriscus and species Parabopyriscus stellatus are deemed to be available from Markham, 1982, not Markham 1985. Hemiarthrus filiformis Chopra, 1923, is transferred to Hyperphrixus Nierstrasz and Brender à Brandis, 1931. The species composition of Eophrixus Caroli, 1930, is reviewed, the type species designation is clarified, and two species of Hypophryxus Shiino, 1934, are transferred into this genus. A key to all genera of Argeiinae and Bopyrinae and keys to species of seven bopyrine genera are provided, as is a list (with hosts) of the 82 bopyrid and ionid species currently known to infest Chinese noncaridean decapods
New pterosaur from Romania.
No full text16 pages : illustrations (some color), map ; 26 cm.We describe a pterosaurian cervical vertebra collected from Maastrichtian sediments at the Pui locality in the Hațeg Basin, Romania. This specimen, a medium-sized, robust fourth cervical, is distinctive in morphology and represents a new, as yet unrecognized, azhdarchid pterosaur size class within the Haţeg Island fauna: it most likely belongs to a new taxon which we opt not to name here. The vertebra is referred to Azhdarchidae based on clearly preserved diagnostic features characteristic of this group and differs in proportions and anatomical details from the recently named azhdarchid Eurazhdarcho langendorfensis Vremir et al., 2013a, from the Sebeș region of the Transylvanian basin. We take issue with claims that all Maastrichtian Romanian azhdarchids (and other penecontemporaneous azhdarchids and azhdarchoids) should be uncritically assumed to be synonymous: it ignores anatomical characters that allow the specimens concerned to be differentiated and is based on an erroneous "one stratum, one species" philosophy contradicted by empirical data from other azhdarchoid assemblages. It has been suggested that the absence of small to medium-sized pterosaurs in Upper Cretaceous sediments is indicative of an evolutionary trend. However, evidence from the Hațeg Island fauna may indicate instead that smaller-sized pterosaurs were indeed present in this interval but remain underrepresented due to rare preservation and collection
