Abstract

The male and female imago of Molleriella kaputu n. sp. are described and figured based on specimens collected in NE Tanzania in 1990. The new species can be separated from M. calcarella Sæther and Ekrem by having a slightly narrower, parallel sided anal point and weaker setae on the inferior volsella, longer C extension and distinctly shorter tibiae. The specimens were caught in Malaise traps at about 1500 m altitude in the Mazumbai Forest Reserve in the West Usambara Mountains.Article submitted 17. June 2014, accepted 29.

Highlights

  • The West Usambara Mountains belong to the Eastern Arch, a chain of isolated mountains stretching from the Taita Hills in southern Kenya and the East and West Usambara and Pare mountains in northeastern Tanzania to the Uluguru and Udzungwa mountains in southern Tanzania

  • The new species is very similar to M. calcarella Sæther and Ekrem in morphological features, but can be distinguished by having slightly more narrow, nearly parallel sided anal point while M. calcarella has a wider, slightly spatulate anal point

  • As the material of M. kaputu was collected in Malaise traps, this species too might well be terrestrial, having originated in the moss or wet soil along the Kaputu Stream
