Biogeographical analysis within the family Phytoseiidae Berlese (Acari: Mesostigmata): an example from the large sub-genus Typhlodromus (Anthoseius) De Leon

Despite their great interest for pest management, the biogeography of the Phytoseiidae is still poorly known. This study focuses on the spatial distribution of one of the largest taxa within the family: the sub-genus Typhlodromus (Anthoseius) currently comprising 322 species. It also provides a description of five discrete morphological characters used to discriminate between species and easily observed. This survey is the first analysis of the combined distribution of both species and associated morphological characters within the family Phytoseiidae. It reveals the great utility of taxonomic data compilation and associated databases for aspects beyong alpha-taxonomy. The highest number of species of Typhlodromus (Anthoseius) was reported from the East Palearctic region and the lowest from the Neotropical province. This was quite surprising as the highest species diversity of Phytoseiidae is reported from this latter region. Several hypotheses are discussed to explain this observation. In provinces showing the highest number of Typhlodromus (Anthoseius) species, we usually also observed the most diverse morphological forms for the five characters considered. High endemism levels were observed in all the provinces considered, even those where only few species were reported (especially the Neotropical province). Possible synonymies are thus discussed, as species could have been described more than once in different biogeographic provinces. Furthermore, some hypotheses are discussed to explain the high species and morphological diversity of the sub-genus Typhlodromus (Anthoseius) in theWest and East Palaearctic regions. Further phylogenetic analyses are required to test these different hypotheses

First record of invasive Stenochrus portoricensis Chamberlin, 1922 (Arachnida: Schizomida: Hubbardiidae) from the Southern region of Brazil

Herein we report for the first time a schizomid for the Southern region of Brazil, Stenochrus portoricensis Chamberlin, 1922 (Schizomida: Hubbardiidae), found in association with termite nests. This is the southernmost record of any schizomid for the Neotropical region. We hypothesize that the species was recently introduced by the sudden population growth of Florianópolis – along with the intense touristic activity – which might have contributed to the inadvertent transportation of this species

Two new feather mite species (Acari, Pteronyssidae) from the white-barred piculet, Picumnus cirratus (Ayes, Piciformes)

Two new species of the feather mite family Pteronyssidae Oudemans, 1941 are described from the white-barred piculet, Picumnus cirratus Temminck from Brazil: Pterotrogus picumni sp. n. and Ramphastobius scutatus sp. n., representing the first mites described from this host. Pterotrogus picumni sp. n. can be readily distinguished from all previous species of the simplex group by having dorsal crest on femora I and II in both sexes. This is the first representative of the genus Pterotrogus Gaud, 1981 recorded on a host of the genus Picumnus Temminck. Ramphastobius scutatus sp. n. is unique among species of the genus by having in both sexes the prodorsal and scapular shields fused into a single propodonotal shield covering all prodorsum. An updated key to known species of the genus Ramphastobius Gaud, 1981 is presented.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP

A new genus and species of pterodectine feather mite (Acari: Proctophyllodidae) from Tod-Tyrants in Brazil (Passeriformes: Tyrannidae)

A new genus and species of feather mite, Hemitriccodectes furcatus gen. nov., sp. nov., is described from passerines of the genus Hemitriccus from Brazil: Hemitriccus furcatus, H. margaritaceiventer and H. striaticollis (Tyrannidae). The new genus belongs to the Pterodectes generic complex and most clearly differs from previously established genera of this complex by the following combination of features: trochanteral setae sRIII are present, and solenidia σ are absent from genua III. The new genus also lacks dorsal hysteroromal setae c1. © 2013 Versita Warsaw and Springer-Verlag Wien

Revision of Nathan Banks type specimens of Bdellidae Dugès (Acari: Trombidiformes) of the Museum of Comparative Zoology, Cambridge

In this article, seven Bdellidae Dugès (Acari: Trombidiformes) of the Museum of Comparative Zoology, originally described by Nathan Banks are studied: Cyta americana (Banks, 1902), Bdella tenella Banks, 1896, Bdella utilis Banks, 1914, Bdella californica Banks, 1904, Bdella cardinalis Banks, 1894, Bdella peregrina Banks, 1894 and Bdella brevitarsis Banks. Bdella tenella and Bdella californica are transferred to the genera Spinibdella and Bdellodes, respectively. Bdella brevitarsis, previously a nomen nudum, is herein described for the first time under the genus Hexabdella. http://zoobank.org/urn:lsid: zoobank.org:pub:A18C8C10-8C8A-4873-AF0B-D1A9164CD7E8 © 2013 Copyright 2013 Taylor & Francis
