125 Additions to the ichthyofauna of Nepal, with a redescription of Neoeucirrhichthys maydelli (Teleostei: Cobitidae) David R. Edds* and Heok Hee Ng ** An increase in ichthyological activity in Nepal over the past 25 years has raised the number of fish species re- ported for the country. We provide details of the distribution of new records for 10 additional species captured from 25 sites during recent ichthyological exploration throughout Nepal: Puntius terio, Psilorhynchus gracilis, Lepidocephalichthys menoni, Neoeucirrhichthys maydelli, Glyptothorax alaknandi, G. botius, G. garhwali, Nangra assamen- sis, Sisor rheophilus, and Anabas cobojius. Given that these species are relatively rare in Nepal, and that their ecol- ogy is poorly understood throughout their range, we also provide notes on their microhabitat use. Neoeucirrhich- thys maydelli, an inadequately-studied species, is rediagnosed and redescribed from the Nepalese material. Ichthyol. Explor.

E-mail: dbsnhh@nus.edu.sg Introduction Kottelat & Whitten (1996) categorized Nepal as one of the countries in Asia where “some (fish) data are available, but their quality and the exist- ing geographical gaps justify extensive field work.” Here, we provide new records for 10 spe- cies captured during recent ichthyological explo- rations in Nepal that are not included in the previous compilations of fishes known to occur in the country. Among the new records is Neoeu- cirrichthys maydelli, a poorly-known species of cobitid loach. Since the Nepalese material repre- sents the first collection of this species in thirty years, N. maydelli is rediagnosed and redescribed in this study. Materials and Methods Fishes were captured by seine, cast net, or electrofisher, and preserved in 10 % formalin solution. Voucher specimens were deposited at: KU, University of Kansas Natural History Museum and Biodiversity Research Center, Lawrence; OSUS, Oklahoma State University Collection of Vertebrates, Stillwater; Tribhuvan Univer- sity Natural History Museum, Swayambhu, Kath- mandu, Nepal; and Fisheries Development Division, Balaju, Kathmandu. For each species, data provided include museum collection number, number of speci- mens, personal collection number, and range of sizes (SL). Where available, habitat data are also presented. Water depth and current speed were measured at 10 points along a transect across the sampled area. Current speed was measured with a Gurley pygmy meter no. 625 (Gurley Precision Instruments, Troy, New York,
