Notes on Hypselostomatidae (Gastropoda: Eupulmonata: Pupilloidea) from Myanmar

Abstract

In this paper we report specimens from Ava (Inn Wa), Myanmar, that are almost identical to the holotype of Boysidia (Bensonella) tianxingqiaoensis T.-C. Luo, D.-N. Chen & G.-Q. Zhang, 2000, a species originally described from Guizhou, China, c. 1020 km to the northeast. This species and Hypselostoma bensonianum W.T. Blanford, 1863 are moved to the genus Gyliotrachela. Additionally, Gyliotrachela muangon Panha & J.B. Burch in Panha et al., 2004 is reported for the first time from the territory of Myanmar. These 3 species are the only representatives of Gyliotrachela known from this country. We illustrate each of them as well as Hypelostoma tubiferum (Benson, 1856), the type species of that genus.
