Revision of the colourful genus Parasetodes McLachlan, 1880 (Trichoptera, Leptoceridae)

Abstract

The rare and beautifully colourful old-world Parasetodes is a so-called set-aside genus with unsettled taxonomy. For instance, a recent survey (Malicky 2006) has synonymised all the Palaearctic and Oriental species to the type species Parasetodes respersellus (Rambur, 1842). The diverse forewing pattern, as a potential diagnostic character state is liable to disappear rapidly in alcohol or denuded and faded even on dry pinned specimens. In this revision we have delineated species by the ventral, surface-perpendicular profile of the dorsal arm of gonopod, the titillating plate, as well as by the lateral profile of the phallic organ and increased the species number of the genus from 12 to 45 describing 33 new species from the Palaearctic, Oriental, and Afrotropical fauna regions. Palaearctic fauna region: Parasetodes temirlik Oláh & Salokannel, sp. nov., Oriental fauna region: P. bali Oláh, sp. nov., P. baoloc Oláh, sp. nov., P. borneo Oláh & Mey, sp. nov., P. dalat Oláh, sp. nov., P. gunung Oláh & Mey, sp. nov., P. hoang Oláh, sp. nov., P. indicus Oláh, sp. nov., P. kambait Oláh & Johanson, sp. nov., P. lamdong Oláh, sp. nov., P. madacus Oláh & Johanson, sp. nov., P. maechaem Oláh & Mey, sp. nov., P. maehong Oláh & Mey, sp. nov., P. namgen Oláh & Johanson, sp. nov., P. nokrek Oláh & Mey, sp. nov., P. pahang Oláh, sp. nov., P. ratnapur Oláh, sp. nov., P. sinicus Oláh, sp. nov., P. tumbang Oláh & Me,y sp. nov., P. umran Oláh & Mey, sp. nov. Afrotropical fauna region: P. amboas Oláh, sp. nov., P. ambovom Oláh, sp. nov., P. barnardi Oláh, Johanson, Mey & Salokannel, sp. nov., P. caprivi Mey & Oláh, sp. nov., P. ikeleng Oláh & Johanson, sp. nov., P. kindam Oláh, sp. nov., P. mahajan Oláh & Johanson, sp. nov., P. meyan Oláh, sp. nov., P. rwandicus Oláh & Me,y sp. nov., P. sikasso Oláh & Johanson, sp. nov., P. tinko Oláh & Johanson, sp. nov., P. weytus Mey & Oláh, sp. nov., P. zambicus Oláh & Johanson, sp. nov. We have reinstated the species status of P. aquilonius Yang & Morse, 1997 stat. restit., P. ussuriensis Martynov, 1935 stat. restit., P. bakeri (Banks, 1913) stat. restit., P. kiangsinicus (Ulmer, 1932) stat. restit., P. maculatus (Banks, 1911) stat. restit., raised the taxonomic status from subspecies to species rank of Parasetodes tanganicanus Marlier, 1956 stat. nov., and transferred Triaenodes demoulini Jacquemart, 1966 to Parasetodes as P. demoulini (Jacquemart, 1966) comb. nov.
