A new genus of Amaurobiidae, Himalmartensus, is described from Nepal, and includes three species: the type species H. martensi new species, H. ausobskyi new species, and H. nepalensis new species. Members of this new genus can be separated from other amaurobiid genera by the combination of the following characters: the presence of a colulus, a single chilum, smooth trichobothrial bases, and simple tracheal tubes. Both promargin and retromargin of Himalmartensus chelicerae have 5–8 teeth and the female epigynum is modified with long and looping copulatory ducts. The spinnerets of all three new species are described and tracheal tubes of H. martensi are examined. Spinnerets, colulus, chilum and tracheal tubes of Himalmartensus are compared to similar genera, including amaurobiids, agelenids, and cybaeids. Himalmartensus is defined as a member of the family Amaurobiidae because of its similarity to the amaurobiids Rubrius and Macrobunus.
