    Långsprötad silverfisk i museer, bibliotek och arkiv i Sverige2018Report (Other academic)
    Abstract [sv]

    Det finns flera syften med denna rapport. Ett är att klargöra utbredningen av långsprötad silverfisk i Sverige, i såväl privatbostäder som i museer, arkiv och bibliotek. Den långsprötade silverfiskens biologi redogörs det också för i detalj utifrån befintlig litteratur. Dels för att synliggöra potentiella angreppspunkter för framtida bekämpningsåtgärder, dels för att utforma en biologiskt understödd riskbedömning för verksamheter som arbetar med samlingar och arkiv. Väldigt knapphändig information har tidigare funnits för beskrivning av typiska silverfiskskador i samlingar och arkiv. Dokumentationen i denna rapport bidrar därför till en ökad förståelse kring hur svårupptäckta skadorna kan vara och synliggör potentiella risker med att angrepp lämnas utan åtgärd. Ytterligare frågeställningar som berörs gäller artens fenologi i Sverige, dess fortsatta spridning samt skadepotential.

    Dyster svävfluga åter i farten i Dalarna2007In: Fauna och flora : populär tidskrift för biologi, ISSN 0014-8903, Vol. 102, no 3, p. 50-54Article in journal (Other (popular science, discussion, etc.))
    Abstract [en]

    Villa occulata was found in a bog in the province of Dalarna, Sweden in 2005 and 2006. Extended search for the species in 2007 showed it to be regularly present in similar mires in the same area. This indicates that the species is resident in Sweden and opens the possibility for further studies of its poorly known distribution and biology. The species seems to be confined to bogs which may explain why it has gone largely unnoticed. The paper summarizes the present state of knowledge.

    Studies on species of Holarctic Pardosa groups (Araneae, Lycosidae). VI. On the identity of Pardosa luciae Tongiorgi with notes on P. trailli (O. P.-Cmbridge) and some other species in the P. nigra-group2004In: Denisia, ISSN 1608-8700, Vol. 12, p. 281-290Article, review/survey (Refereed)
    Abstract [en]

    The identity of Pardosa luciae Tongiorgi, said to occur in the Swiss Alps, is discussed. It is argued that the description was based on a misplaced male palp of the Nearctic species P. uintana Gertsch. Consequently, P. luciae is removed from current synonymy with the European species P. trailli (O. P.-Cambridge) which is known from Britain and Scandinavia (distribution meapped). Within the P. nigra group of species, P. trailli (with Lycosa carnifex Collett here placed as junior synonym), P. eiseni (Thorell) and P. uintana constitute a close group of species sharing a helical configuraton of the apical part of the embolus. Characteristics of these species and of P. giebeli (Pavesi), endemic to the Central European Alps, are illustrated.

    Fixation of Lycosa fidelis =. Pickard-Cambridge, 1872 as the type species for the genus Wadicosa Zyuzin, 1985 (Araneae: Lycosiadae), with a redescription of the species2009In: Contributions to Natural History, ISSN 1660-9972, Vol. 12, p. 813-828Article, review/survey (Refereed)
    Abstract [en]

    The name Lycosa or Pardosa venatrix has been used since Simon in 1882 to denote a widespread Palearctic species. The nominal species Lycosa venatrix Lucas, 1846 was originally designed as the type species for the genus Wadicosa Zyuzin, 1985. It has, however, been recognized that the species long known as venatrix was misidentified: the species so named by Lucas is evidently not a species of Wadicosa. Therefore, we now fix Lycosa fidelis O. P.-Cambridge, 1872, the species actually involved in the misidentification, as the type species for Wadicosa. An emended diagnosis for the genus Wadicosa is given, as well as a redescription of W. fidelis. The presence of some hitherto unrecorded structures in the male palp is emphasized. A hypothetic view on the mating mechanism in W. fidelis is presented.
