A NEW SPECIE OF THE GENUS Leptus (TROMBIDIFORMES: ERYTHRAEIDAE) PARASITIZING Panstrongylus megistus (INSECTA: HEMIPTERA: REDUVIIDAE) UMA NOVA ESPÉCIE PARA O GÊNERO Leptus (TROMBIDIFORMES: ERYTHRAEIDAE) PARASITANDO Panstrongylus megistus (INSECTA: HEMIPTERA: REDUVIIDAE) F.C. Jacinavicius 1, R. Bassini-Silva 1,2 , R. Haitlinger 3, R.H.P. Moraes 1 & D.M. Barros- Battesti 1,2 1Laboratório Especial de Coleções Zoológicas; Instituto Butantan, São Paulo, SP; 2Departamento de Medicina Veterinária Preventiva e Saúde Animal, FMVZ-USP, São Paulo, SP; 3Department of Invertebrate Systematics and Ecology, Institute of Biology, Wrocław University of Environmental and Life Sciences, Poland. Twenty nine species of the genus Leptus are known from Neotropical region. In Brazil there are 9 known species: L. adaminae Haitlinger, L. alberti Haitlinger, L. cyryli Haitlinger, L. fozicus Haitlinger, L. iguacuicus Haitlinger, L. mariani Haitlinger, L. onnae Haitlinger, L. stieglmayri (Oudemans) and L. stolae Haitlinger. Larvae of velvet mites are ectoparasites of arthropods while adults are predators. Some larvae of Leptus were collected on bloodsucking bug, Panstrongylus megistus (Burmeister) from Jardim Amaralina, São Paulo city, State of São Paulo. The bloodsucking bugs are considered vectors of Chagas Disease in Brazil. The velvet mites were prepared in Hoyer´s medium and measured under microscope NIKON Eclipse E200 coupled to NIS-Elements BR measurements system, v.3.33.13. Drawings were prepared in Inkscape program. Here we present the diagnosis of this new species of Leptus : 1 palpgenuala and 1 palpfemorala; 4 setae between coxae II-III; fD=45; fV=36; NDV= 81; GL = 222; AL= 66-71; PL=72-73; Palpal se tal formul a: O-1B-1B-3B-2N-4B-1ω; number of setae on Ta I-II-III (24-25-25); on Ti I-II-III (14-14-15) and Ge I-II-III (8-8-8). The Holotype (IBSP 12052) and 8 Paratypes (IBSP 12023) of Leptus n. sp. are deposited at the Coleção Acarológica do Instituto Butantan (IBSP). The host was also deposited at the Coleção Entomológica do Instituto Butantan (IBSP 1006). This is a new species of Leptus and P. megistus is recorded for the first time as a host for this genus.

The Natural History Museum in Görlitz has a long history of soil-zoological research, so that it was only logical that the Bibliographia be extended by this third, important soil-mite group.

Collier of Invertebrate Fossils: Conodonta SMITHSONIAN CONTRIBUTIONS TO PALEOBIOLOGY NUMBER 9 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of profes sional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These publications are distributed by mailing lists to libraries, laboratories, and other in terested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.

The literature databank on Actinedida presently comprises 5,171 papers on 1,624 species. Since the literature of the Actinedida is vast, we have excluded as in past volumes two major taxa from the database: Eriophyidae and the paraphyletic group “Hydracarina”, since these are available elsewhere. The Tarsonemidae have been included since 2006, uniting the Bibliographia Actinedida with the Bibliographia Tarsonemidologica formerly published by RACK and MAHUNKA. The publications cited here reflect the worldwide research interest on the taxonomically difficult Actinedida. The present volume includes publications by researchers from 31 countries and 6 continents. The majority of first authors listed in this year’s volume come from Brazil (14%), Japan (11%), the USA (10%) and India (6%). However, contributions come from many disparate countries, including Turkmenistan, Sri Lanka, Iran and Turkey.

The former species was found in the soil and vegetation of a mesophytic meadow, whereas the latter was registered walking alive in a dry insect collection box.

Mites Associated with Forest Insects
MITES ASSOCIATED WITH FOREST INSECTS PREPARED BY: JOHN C. MOSER FOR WILLAMETTE INSTITUTE FOR BIOLOGICAL CONTROL, INC. MONROE, OR 97456 JANUARY 1995 INTERIOR COLUMBIA BASIN ECOSYSTEM MANAGEMENT PROJECT CONTRACT # 43-OEOO-4-9278 Narativ2 1994: Dee 9,10,12,Jan 10,11,12,13,25 Reply to Roger Sandquist’s DG memo of Dee 8, requesting the expansion of the narrative report for the key environmental factors and partial correlations, the key ecological functions, special habitats, and management scenarios. Figures 1 and 2 and other selected sections from the draft of Narrativ.CRB forwarded to Sandquist Nov 21 is included in this draft of Narativ2; other sections of the original Narrativ.CRB are incorporated in the comment sections of CRBFORMS 1-7. The food chain relationships may be complex as illustrated by Kinn (1971) for the bark beetle, Ips paracunfisus (Fig. 1). This emphasizes that one cannot just discuss the mites without also taking into consideration the host insect, fungi, and nematodes. They all interact and depend on one another in the galleries; this is best illustrated by the keystone species, Tarsonemus n. sp. and its mutualism with the bark beetle mycangial fungus. Fig. 1. Food chain relationships among some of the mites species, fungi, and nematodes found in the galleries of Ipsparuconjks. Broken lines indicated possible food relationships. (After Kinn, 1971). The association/predation index devised by Wilson (1980) is a useful tool for predicting the impact of mites on their phoretic hosts. Figure 2 (after Stephen et al.) shows that the closer the phoretic relationship between a mite and bark beetle (as measured by the index of association), the less threat that mite may be to the beetle.
