Revision of the African Neoperla Needham, 1905 (Plecoptera: Perlidae: Perlinae) based on morphological and molecular data Author Zwick, Peter 0000-0002-6730-0011 pleco-p.zwick@t-online.de Author Zwick, Andreas 0000-0002-7532-1752 andreas.zwick@csiro.au text Zootaxa 2023 2023-07-17 5316 1 1 194 http://dx.doi.org/10.11646/zootaxa.5316.1.1 journal article 10.11646/zootaxa.5316.1.1 1175-5326 8154005 BC922E16-2614-4F3D-AD82-87A845DE7E2B 78. Neoperla sjostedti Klapálek, 1909 The species is well defined morphologically and by DNA. However, since the amount of material suitable for molecular study differed much between the included three morphs, coverage is therefore very unequal. Two of the morphs fit the types of historical nominal species and are recorded as N. sjostedti sjostedti Klapálek,1909 and N. sjostedti needhami Lestage, 1921 , respectively. Both vary and females cannot reliably be identified. Male morphology suggests the taxa are essentially allopatric, with a suspected contact zone at Tukuyu, near Lake Malawi in the Great Rift Valley ( Fig. 458 , arrow) where intermediate morphs possibly occur. Of the third morph only the female is known, DNA and morphology agree between the eight individuals which form a homogeneous block within the complex. The morph is briefly described but not named.
