Hypselostoma piconis — van Benthem Jutting 1950: 24, 42, fig. 13; Maassen 2001: 77. Type material examined. Malaysia • 1 paratype; from the type locality; Raffles Museum, Singapore ex. coll.; RMNH.Moll.140161. Additional material examined. Malaysia • 9 shells; Perak, 8–10 km northeast from Sungai Siput, east from Batu Lima, cave temple; 04°51.985'N, 101°07.333'E; 70 m a. s. l.; 07 Jan. 2013; A. Hunyadi leg.; coll. HA. Type locality. “ Sungei Siput, Perak ”, Malaysia. Differential diagnosis. Hypselostoma piconis is strikingly similar to H. luctans from which it can be separated by the appearance of the apertural barriers, most importantly the concrescent angular and parietal lamellae, which are separate in H. luctans. Distribution. This species is known only from the type locality and its surroundings. Remarks. The fact that the major difference between H. piconis and H. luctans is the appearance of the barriers on the parietal side further supports the indistinctness of Gyliotrachela and its synonymy with Hypselostoma.
