Abstract
A new species of Baetidae, Gratia baibungensis sp. n., is described and illustrated based on nymphal stage collected from the southeastern Tibet (Xizang) and the genus is reported for the first time from China. This new species can be readily differentiated from its congeners by the absence of a protuberance on the posterior margin of the abdominal tergum X, glabrate simple submarginal setae on the labrum, and the posterior margin of sterna VI–IX having much longer spatulate setae.
Highlights
The Eastern Himalayas is situated between the west of central Nepal and east of Myanmar, through southeastern Tibet in China to northeastern India
The present study deals with an undescribed species of the genus Gratia collected from southeastern Tibet
The genus Gratia resembles Jubabaetis Müller-Liebenau in appearance by the presence a regular row of ciliate bristles on the dorsal margin of the femur, the protuberance on the posterior margin of abdominal terga, and the terminal filament reduced to one segment (Müller-Liebenau 1980)
Summary
The Eastern Himalayas is situated between the west of central Nepal and east of Myanmar, through southeastern Tibet in China to northeastern India. In southeastern Tibet, as a part of the Eastern Himalayas, the aquatic insect. You (1987) reported 13 mayfly species in Tibet, of which only 4 species were collected from the southeastern Tibet. In 2010, we conducted an exploration on the aquatic insect fauna in southeastern Tibet. Except for some species which are probably endemic to this region, most of mayfly fauna elements belong to the Indo-Malayan ecozone. The present study deals with an undescribed species of the genus Gratia collected from southeastern Tibet
