How many species of mite-harvestmen (Opiliones, Cyphophthalmi) are there in Austria?

Der bodenbewohnende Milbenkanker Cyphophthalmus duricorius Joseph, 1868 (Fam. Sironidae) galt mehr als 60 Jahre lang als die einzige in Österreich vorkommende Art der Weberknecht-Unterordnung Cyphophthalmi. Neuere Aufsammlungen zeigen jedoch, dass mindestens zwei weitere Cyphophthalmi-Arten in Österreich existieren: 1) Siro cf. crassus Novak & Giribet, 2006 wurde an einer Lokalität in der SW Steiermark nahe der slowenischen Grenze gefunden und repräsentiert eine zweite Gattung von Sironiden in Österreich. 2) Ein weiterer, morphologisch distinkter Sironide („Sironidae gen. et sp. nov.?“) − derzeit noch unbeschrieben und taxonomisch nicht zugeordnet − stammt aus Böden im Grenzgebiet Steiermark-Kärnten. Obwohl bislang kein syntopes Vorkommen belegt ist, können alle drei Arten in einem kleinen Areal von wenigen Quadratkilometern gefunden werden.For the last 60 years, the mite-harvestman Cyphophthalmus duricorius Joseph, 1868, a soil-dwelling sironid, has been considered to be the only representative of the opilionid suborder Cyphophthalmi in Austria. However, novel data from recent collections confirm the presence of at least two further Austrian cyphophthalmid species. (1) Siro cf. crassus Novak & Giribet, 2006 occurs in at least one location in SW Styria near the Slovenian border and hence represents a member of a second genus of Austrian sironids. (2) A further morphologically distinct sironid (“Sironidae gen. et sp. nov.?”) – so far undescribed and systematically not placed in detail – was collected in the borderland between Styria and Carinthia. All three species can be found in a small area of a few square-kilometers; although no syntopic occurrence was recorded

CDR2L Is the Major Yo Antibody Target in Paraneoplastic Cerebellar Degeneration

The pathogenesis of Yo‐mediated paraneoplastic cerebellar degeneration (PCD) is unclear. We applied cerebrospinal fluid and serum from PCD patients as well as CDR2 and CDR2L antibodies to neuronal tissue, cancer cell lines, and cells transfected with recombinant CDR2 and CDR2L to elucidate which is the major antigen of Yo antibodies. We found that Yo antibodies bound endogenous CDR2L, but not endogenous CDR2. However, Yo antibodies can bind the recombinant CDR2 protein used in routine clinical testing for these antibodies. Because Yo antibodies only bind endogenous CDR2L, we conclude that CDR2L is the major antigen of Yo antibodies in PCD.publishedVersio

Naphthoquinones and Anthraquinones from Scent Glands of a Dyspnoid Harvestman, Paranemastoma quadripunctatum

Extracts of Paranemastoma quadripunctatum (Opiliones, Dyspnoi, Nemastomatidae) contained seven components, all of which likely originated from the secretion of well-developed prosomal scent glands. The two main components (together accounting for more than 90% of the secretion) were identified as 1,4-naphthoquinone and 6-methyl-1,4-naphthoquinone. The minor components were 1,4-naphthalenediol, two methoxy-naphthoquinones (2-methoxy-1,4-naphthoquinone, and 2-methoxy-6-methyl-1,4-naphthoquinone) and two anthraquinones (2-methyl-9,10-anthraquinone and a dimethyl-9,10-anthraquinone). While some chemical data on scent gland secretions of the other suborders of Opiliones (Cyphophthalmi, palpatorean Eupnoi, and Laniatores) already exist, this is the first report on the scent gland chemistry in the Dyspnoi. Naphthoquinones are known scent gland exudates of Cyphophthalmi and certain Eupnoi, methoxy-naphthoquinones and anthraquinones are new for opilionid scent gland secretions
