Abstract
During several excursions to the Chin Hills of Myanmar from 2001 to 2015, rich collections of caddisflies were made which form the basis of the present taxonomic and biogeographic study. A total of 106 species were identified including seven new species. They are described as Arctopsyche subflavasp. nov., Hydromanicus abdominalissp. nov., Cheumatopsyche janosolahisp. nov., Lepidostoma subpanaitossp. nov., Aplatyphylax pumilussp. nov., Adicella natmataungensissp. nov. and Triaenodes mindatensissp. nov. Illustrations of the male genitalia and images of the adults are provided. Two species names were recognised as junior synonyms: Hydropsyche athamas Malicky & Chantaramongkol, 2000, = Hydropsyche januha Oláh & Barnard, 2008, syn. nov.; Hydropsyche khasigiri Oláh & Barnard, 2008, = Hydropsyche kiogupa Oláh & Schefter, 2008, syn. nov. In an attempt to determine the biogeographic character of the fauna, the known ranges of all resident species were plotted into three longitudinal transects from 85°–95°E, 95–98°E and 98°–108°E, ranging from the eastern Himalayas to northern Vietnam. About half of the species have ranges extending over all three transects. The fauna is equally composed of western and eastern species qualifying the Chin Hills as part of a transition zone including palearctic elements. Most of the species, which are widely distributed in south-east Asia, are members of the suborder Annulipalpia. The investigations of the authors yielded 77 autochthonous species, which have been unrecorded from the country including the newly-described taxa. This brings the number of species records from Mynamar to 304.
Highlights
Local inventories are key data resources for measuring insect diversity, recognising ranges of taxa and planning conservation activities
The purposes of the present article are to summarise all data on Trichoptera collected by the author and Stefan Naumann (SN) in the Chin Hills including the National Park (NTNP) and to provide further new taxa descriptions. This information was used as an initial attempt to recognise species distribution patterns in SE Asia and to determine the biogeographic character of the fauna of the Chin Hills
Caddisflies were collected during various months in the Chin Hills from 2001 to 2015
Summary
Local inventories are key data resources for measuring insect diversity, recognising ranges of taxa and planning conservation activities. This task was accomplished by Wityi et al (2015), who retrieved and compiled all species description from the various publications of Martynov, Mosely, Kimmins, Schmid, Malicky and others They provided the first synopsis of the Trichoptera of Myanmar, based on literature, but with the addition of results from their own fieldwork in the Chin Hills in Myanmar from 2012–2014. The purposes of the present article are to summarise all data on Trichoptera collected by the author and SN in the Chin Hills including the NTNP and to provide further new taxa descriptions This information was used as an initial attempt to recognise species distribution patterns in SE Asia and to determine the biogeographic character of the fauna of the Chin Hills. The traditional way of life of the local Chin people and extensions of other agricultural activities are major threats to the National Park (see Fig. 2H)
