Zora Spinimana
''Zora spinimana'' is a prowling spider of the family Miturgidae with a Palearctic distribution. It is the type species of the genus ''Zora (spider), Zora''. Description The females are 5-7.7 mm in length, the males 4.5–5 mm. The epigyne has a small groove and a larger spermatheca. The species is very similar to ''Zora silvestris'' but the brown lateral bands on the carapace are narrower than the yellow bands, whereas in ''Z. silvestris'' the brown lateral bands are wider than the yellowish bands. ''Z. spinimana'' is slightly larger than ''Z. silvestris'' and the overall yellow colour of ''Z. spinimana'' has a warmer hue. ''Z. spinimana'' has three pairs of ventral spines on metatarsus I and II, but ''Z. silvestris'' has only two.

Carl Jakob Sundevall
Carl Jakob Sundevall (22 October 1801, Högestad – 2 February 1875) was a Swedish zoologist. Sundevall studied at Lund University, where he became a Ph.D. in 1823. After traveling to East Asia, he studied medicine, graduating as Doctor of Medicine in 1830. He was employed at the Swedish Museum of Natural History, Stockholm from 1833, and was professor and keeper of the vertebrate section from 1839 to 1871. He wrote ''Svenska Foglarna'' (1856–87) which described 238 species of birds observed in Sweden. He classified a number of birds collected in southern Africa by Johan August Wahlberg. In 1835, he developed a phylogeny for the birds based on the muscles of the hip and leg that contributed to later work by Thomas Huxley. He then went on to examine the arrangement of the deep plantar tendons in the bird's foot. This latter information is still used by avian taxonomists. Sundevall was also an entomologist and arachnologist, for which (for the latter field) in 1833 he publish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
