A new species of Peacock Spider from Western Australia.


Peacock Spiders, Maratus spp., are a group of small Jumping Spiders, Salticidae, found only in Australia. The group gets its name from the bright colours and elaborate courtship dances of the male Spiders. The males have flaps on the sides of their abdomens which they open to increase the area of body used in the display, further increasing their resemblance to Peacocks.

In a paper published in the journal Peckhamia on 8 June 2014, Jürgen Otto of St. Ives, New South Wales, and David Hill of Simpsonville, South Carolina, describe a new species of Peacock Spider from the Warwick Open Space and Gnangara Mound areas to the north of Perth in Western Australia.

The new species is named Maratus clupeatus, meaning ‘shield-bearing’, a reference to the shape of the male’s fan (abdomen with opened flaps) which resembles a medieval shield when raised during the mating display. Only the male of the species is described, these reach about 4.1 mm in length, and are black or dark brown in colour, with white hairs on the limbs and an area of brown scales on the head. The abdomen is brightly coloured, being light blue or blue-green to purple with orange or red-orange patterning.

  1. Herpes Virus is a terrible virus, if not for my Husband and the help of the great Dr.Alabi my life would have been a mess! I was diagnose with Herpes virus in 2012, my husband encouraged me, and told me not to lose hope, I manage to give birth to a baby Boy who was free from this virus, and my Husband was always there for me! One day he came to me and told me that he have found a man who can cure me. Base on scientist, they said there is no cure for Herpes virus; he told me that he has seen many testimonies about him on the internet. We decided to contact him, we filled his Herbal home form, and he asked us to buy some local root and herbs items which we did! and he prepared for me a herbal medicine and 14 days later he asked me to go for medical test, faithfully hopefully i went for the medical test, and Behold, I was cured, from this virus and its was not found in my Body system again...
