Rediscovery of Metacnemis angusta (Selys) in the Western Cape, South Africa, with description of male and redescription of female (Zygoptera: Platycnemididae)

M. angusta was described from a 2 type in 1863, which has since been lost. The only other specimen is another 9 taken in 1920 in the Western Cape, South Africa. The sp. was feared extinct, but a population was discovered in November 2003. The 3 is described here as a neotype, along with a redescription of the 2 as a paratype. Although the conservation status of the sp. has improved, it is still threatened, principally by invasive alien trees.
