A catalog of the described Opilioacaridae species and their type depository institutions is presented. Opilioacaridae comprises 53 valid taxa (with 2 subspecies and 3 fossil species) distributed in 13 genera. The zoogeographical distribution, described life stages and years of description are also provided and discussed. Recent work on the American continent has resulted in a great diversity from these zoogeographical zones, but the family has a worldwide distribution. In addition, we move Neocarus ojastii Lehtinen, 1980 into Caribeacarus, i.e., Caribeacarus ojastii (Lehtinen, 1980) n. comb.

Abstract Bryozoans with calcified frontal shields formed by the fusion of costae, collectively constituting a spinocyst, are traditionally assigned to the family Cribrilinidae. Today, this family is regarded as nonmonophyletic. In the Argentine Cenozoic, cribrilinids were until recently represented by only two fossil species from the Paleocene of Patagonia. This study describes the first fossil representatives of Jolietina and Parafigularia: J. victoria n. sp. and P. pigafettai n. sp., respectively. A fossil species of Figularia, F. elcanoi n. sp., is also described. The material comes from the early Miocene of the Monte León and Chenque formations (Patagonia, Argentina). For comparison, we also provide redescriptions of the remaining extant species of Jolietina: J. latimarginata (Busk, 1884) and J. pulchra Canu and Bassler, 1928a. The systematic position of some species previously assigned to Figularia is here discussed. Costafigularia n. gen. is erected, with Figularia pulcherrima Tilbrook, Hayward, and Gordon, 2001 as type species. Two species previously assigned to Figularia are here transferred to Costafigularia, resulting in C. jucunda n. comb. and C. tahitiensis n. comb. One species of Figularia is reassigned to Vitrimurella, resulting in V. ampla n. comb. The family Vitrimurellidae is here reassigned to the superfamily Cribrilinoidea. The subgenus Juxtacribrilina is elevated to genus rank. Inferusia is regarded as a subjective synonym of Parafigularia. Parafigularia darwini Moyano, 2011 is synonymized with I. taylori Kuklinski and Barnes, 2009, resulting in Parafigularia taylori n. comb. Morphological data suggest that these genera comprise different lineages, and a discussion on the disparities among cribrilinid (sensu lato) spinocysts is provided.

The record of the fossil representatives of the family Juliidae is updated. The new genus Candinia is proposed, in the subfamily Juliinae, for two fossil species somewhat intermediate between Julia and Berthelinia. The new species Candinia pliocaenica is recorded from the lower Pliocene shallow marine deposits near Siena (Tuscany, Italy). This is the first record of Sacoglossa in the Mediterranean Basin. Based on the very specialized life habits of the Juliidae, it is suggested that subtropical Caulerpa algal prairies inhabited the Mediterranean during the early Pliocene, likely becoming extinct in this basin because of the mid-Pliocene climatic deterioration.

The stable fly, Stomoxys calcitrans (L.) is a blood-sucking muscid fly species, with a worldwide distribution and high veterinary-medical importance. In this study, four mite species were collected from stable flies in Hungary. One mite species (Trichotrombidium muscarum (Riley, 1878)) from the family Microtrombidiidae was parasitic on the flies, collected in high numbers from their bodies. The other three species were found in small numbers on the flies, which they use only for transportation. The latter included the phoretic female of Pediculaster mesembrinae (Canestrini, 1881) (Acari: Siteroptidae), the phoretic deutonymph of the Halolaelaps sexclavatus (Oudemans, 1902) (Acari: Halolaelapidae) and Macrocheles subbadius (Berlese, 1904) (Acari: Macrochelidae). This is the first record of an association between the stable fly and two mite species (Trichotrombidium muscarum and Halolaelaps sexclavatus). A new, completed list and identification key of known stable fly associated mites are also provided.

Background: Molluscum contagiosum virus (MCV) is a large double-stranded DNA virus that is a member of the family Poxviridae, and which has a worldwide distribution. As with other poxviruses, MCV does not appear to develop latency but evades the immune system through the production of viral specific proteins. Objective: To evaluate the therapeutic efficacy of imiquimod 5% cream for MCV. Methods: Thirteen children >5 and <10 years old, 19 immune-competent adults and four adults with advanced, but stable HIV-1 disease with >10 MCV lesions were treated with topical 5% imiquimod cream three times weekly for up to 16 weeks. Results: Fourteen of 19 immune-competent adults, four of four adults with HIV-1 disease, and six of 13 children had resolution of their MCV lesions in <16 weeks of imiquimod therapy. Children tended to have more pruritus and inflammatory reactions with imiquimod, although most treated lesions appeared to respond. The development of new MCV lesions resulted in a lower overall resolution of the lesions in children. Imiquimod appeared to be the most efficacious in patients with HIV-1 disease and in the genital area in immune-competent adults. Conclusion: Although topical imiquimod appears to have some efficacy in the therapy of MCV, in children the pruritus correlated relatively well with the development of new lesions. In adults, areas that would be expected to have better penetration appeared to respond more consistently. Although the HIV-1-positive patients had the largest clinical lesions at the onset of therapy, as a group they had the best overall response to therapy.

Abstract U. agropyri causes flag smut on leaves of species in the family Poaceae. As a pathogen of grasses, it appears to have a wide host range (Mordue and Waller, 1981) and a worldwide distribution (UK CAB International, 1991). However, some authorities do not include the pathogen on wheat [Triticum aestivum], identified as Urocystis tritici, within U. agropyri. Rossman et al. (2006) place U. agropyri in the category of a "Threat to Major Crop Plants" and wheat and wheat straw imports are restricted in North America (Anon., 2005; CFIA, 2008). If the widespread species includes the wheat pathogen, then it is already present on all continents with agriculture and in major wheat-growing areas (Purdy, 1965), so it has already been introduced and may be difficult to exclude from additional areas. Both smuts are seed- and soil-borne, causing systemic infections that can be perennial in weeds and graminaceous crops, including turfgrasses. The spore balls are windborne (Purdy, 1965) and prevention of spread among wild grasses on land is not amenable to control.

AbstractThe nemonychid, Libanorhinus succinus gen. & sp. n. represents the first weevil to be reported from Lebanese amber and the first formal description of a representative of the family Nemonychidae from any amber source. The specimen is placed in the extinct subfamily Eobelinae on the basis of its elytral punctures lined up to form striae, the presence of scutellar strioles and the possession of simple claws. The vertex of the head, antennal insertions at about the apical quarter of the rostrum and abdominal ventrites distinguish it from previously described fossil species in the Eobelinae. Since many extant nemonychids feed and develop in the male cones of representatives of the Araucariaceae, the present fossil could have developed in the cones of this resin-producing tree family.

A protonymph of the snout mite genus Odontoscirus Thor, 1913, O. cretacico sp. nov., is described and illustrated from Cretaceous amber of Myanmar is described and illustrated, constituting the earliest fossil species described of the family Bdellidae (ca. 99 Ma). After reexamining the literature and recollected specimens from type localities, we conclude that the following five recent species do not belong to the genus Biscirus and should be transferred to Odontoscirus: O. anomalicornis (Berlese 1916) comb. nov., O. symmetricus (Kramer 1898) comb. nov., O. uncinatus (Kramer 1898) comb. nov., O. norvegicus (Thor 1905) comb. nov., and O. insularis (Willmann 1939) comb. nov. The implications of the fossil record of the family is discussed.

AbstractOligoneuriidae is a Pantropical family of Ephemeroptera, with 68 species described in 12 genera. Three subfamilies are recognized: Chromarcyinae, with a single species from East Asia; Colocrurinae, with two fossil species from Brazil; and Oligoneuriinae, with the remaining species distributed in the Neotropical, Nearctic, Afrotropical and Palaearctic regions. Phylogenetic and biogeographical analyses were performed for the family based on 2762 characters [73 morphological and 2689 molecular (COI, 16S, 18S and 28S)]. Four major groups were recovered in all analyses (parsimony, maximum likelihood and Bayesian inference), and they were assigned to tribal level, namely Oligoneuriini, Homoeoneuriini trib. nov., Oligoneuriellini trib. nov. and Elassoneuriini trib. nov. In addition, Yawari and Madeconeuria were elevated to genus level. According to Statistical Dispersal-Vicariance (S-DIVA), Dispersal Extinction Cladogenesis (DEC) and divergence time estimation analyses, Oligoneuriidae originated ~150 Mya in the Gondwanan supercontinent, but was probably restricted to the currently delimited Neotropical region. The initial divergence of Oligoneuriidae involved a range expansion to Oriental and Afrotropical areas, sometime between 150 and 118 Mya. At ~118 Mya, the family started its diversification, reaching the Nearctic through dispersal from the Neotropical region and the Palaearctic and Madagascar from the Afrotropical region.

The mammalian order Xenarthra (including the living Neotropical armadillos, anteaters, and tree sloths) has figured importantly in recent hypotheses of interordinal relationships among eutherian mammals. It has been suggested that the group shares a common ancestry both with the extant Old World order Pholidota (i.e. the pangolins or scaly-anteaters) and the extinct North American group Palaeanodonta. Furthermore, these three groups have been linked together into a monophyletic Cohort Edentata, which has been hypothesized to represent the sister-group to all other eutherians. This placement of edentates relative to the remainder of Eutheria has been supported in part by a purported difference in the morphology of the stapes in the two groups- edentates possessing a primitive, imperforate/columelliform morphology, other placentals a derived, perforate/stirrup-shaped morphology.A recent study of stapedial morphology among mammals by Novacek and Wyss (1986) suggests that within the Xenarthra itself a perforate stapes is found among armadillos, but that the pilosa in particular (the clade including anteaters and sloths) and the order as a whole are characterized primitively by an imperforate stapes. Our studies of the xenarthran ear region (Patterson et al., in press) have uncovered new ontogenetic and paleontological evidence which contradict the findings of Novacek and Wyss. Among adults of the two extant tree sloth genera, the stapes lacks a stapedial foramen. However, in both genera, this adult imperforate morphology is derived from a perforated juvenile stapes. Novacek and Wyss ignored fossil species in their consideration of the xenarthran stapes. It has long been known that extinct ground sloths of the family Mylodontidae possessed a large stapedial foramen. Unfortunately, until now no stapes were known from the remaining ground sloth families, the Megatheriidae and the Megalonychidae. We have uncovered a complete left stapes of an early Miocene megatheriid ground sloth Eucholoeops ingens. This stapes possesses a well-developed stapedial foramen. We believe that this new paleontological evidence, combined with our information on the ontogeny of the stapes in the living genera, clearly indicates that a perforate stapes is primitive for sloths. Moreover, when we plot distributions of stapedial morphologies of both living and fossil edentates onto a phylogeny of the Edentata, we can demonstrate that the a large stapedial foramen is primitive for the Xenarthra as a whole, and probably for the entire Cohort Edentata. Such a distribution makes it unlikely that stapedial morphology can be used to separate edentates from other eutherian mammals.
