Insights into the distribution and ecology of the funnelweb spider Macrothele calpeiana in Portugal

  Insights into the distribution and ecology of the funnelweb spider Macrothele calpeiana in Portugal Abstract Biodiversity surveys are critical to prevent decline and extinction of ill-/unknown species through timely conservation action. This is particularly relevant when the species are neither iconic nor flagships, therefore lessening the potential for accessing conservation means, such as in the case of the mygalomorph spider Macrothele calpeiana. The species is endemic to southern Iberia but its distribution and ecology is barely documented in Portugal. Therefore, we made a comprehensive survey throughout its estimated range in the south of the country. The species is spread unevenly and patchily throughout low mountainous terrain in south/southwest Portugal, preferably along shale/ greywacke/clay roadside banks. It seems rare in the surrounding limestone area to the south and absent from the peneplain to the north. The webs were found in groups averaging 10.0±15.2 webs/site a...

New species and records of Otiothops MacLeay, 1839 (Araneae, Palpimanidae) from caves of the Carajás region, state of Pará, Brazil

Abstract

In this paper, we describe three new species of the palpimanid spider genus Otiothops MacLeay, 1839 from caves of the Carajás region, in the state of Pará, Brazil, based on specimens of both sexes: O. fatimae sp. nov. (♂♀), O. luizi sp. nov. (♂♀) and O. daselva sp. nov. (♂). Otiothops baculus Platnick, 1975 and O. curua Brescovit, Bonaldo & Barreiros, 2007 are also recorded from the same cave areas for the first time, and their distributions are updated.
