Menemerus guttatus

Species of spider

Menemerus guttatus is a species of jumping spider in the genus Menemerus that lives in Morocco. The spider has been found in the High Atlas mountains in gravel rivers. It displays complex courtship patterns. The species was first described in 1999 by Wanda Wesołowska, one of over 500 descriptions she has made during her lifetime. The spider is small, with a dark brown, nearly black carapace that is between 2.8 and 3.5 millimetres long and a dark brown abdomen between 2.5 and 5.6 millimetres long. The female is larger than the male. It can be distinguished from other species in the genus by the pattern on its abdomen, which consists of two lines of white patches that converge to the back of the spider. Otherwise, it is the copulatory organs that most identify the species. The male has a distinctive relatively wide and short embolus and lamella and two similar appendages at the base of the palpal bulb, or apophyses. The female has a complex internal structure of the epigyne including crescent-shaped chambers and circular spermathecae.
