Poecilochroa Senilis
''Poecilochroa'' is a genus of ground spiders that was first described by Niklas Westring in 1874. Description As Gnaphosidae, ''Poecilochroa'' have large cylindrical spinnerets. They are nocturnal, spending the day in silken retreats and going out at night to hunt. ''Poecilochroa'' are divided into two gnaphosid groups based on their abdomen colouration: those with plain abdomens are in the ''Echemus'' group, while those with black and white abdomen are in the ''Herpyllus'' group. Males of both groups have well-developed dorsal scuta. Habitat ''Poecilochroa'' occur in various habitats including on and under stones and dead leaves, on vegetation, in steppes, grasslands, dry fields, stream beds and forest floors. Species it contains thirty-nine species and one subspecies: *'' Poecilochroa albomaculata'' (Lucas, 1846) – Western Mediterranean *'' Poecilochroa alcala'' Barrion & Litsinger, 1995 – Philippines *''Poecilochroa anomala'' (Hewitt, 1915) – South Africa *'' ...

Niklas Westring
Niklas Westring (13 November 1797, in Gothenburg – 28 January 1882) was a Swedish entomologist and arachnologist. He started out with the intention to study medicine but this was frustrated by the death of his father. His full-time profession from 1816 was as a customs officer in Gothenburg, where he was customs administrator from 1834 to 1856. When he retired he spent most of his time working on natural history, especially from 1840 to 1862, during which time he also became a conservator at the Göteborg Natural History Museum. He is best known for his book ''Araneae suecicae descriptae'' in 1862 in which he described 308 species of spider found in Sweden. Of these, 124 had already been described by Carl Linnaeus, Charles De Geer and Carl Jakob Sundevall. He appears to have been something of a mentor to Tamerlan Thorell who lived in Gothernborg until he went to university at Uppsala and was familiar with Westring's collection of spiders and how to identify them since he had be ...
