Remarks. I. nepalicum  is closely related to three very similar apterous and endemic Nepalese species of the I. pictum  species group: I. nepalense  , I. jaljalense  , and I. jumla  sp. n. In a previous key ( Kocian, 2003), the absence of an ocular puncture and seta was used for distinguishing I. nepalicum  from similar species. In the material listed above we found specimens of I. nepalicum  with similarly developed ocular puncture and seta as in I. nepalense  . Therefore, a reliable identification is possible only based on the male sexual characters, above all the chaetotaxy of the male sternite VIII in combination with the shapes of the internal structures of the aedeagus. The shape of large paired sclerites in the internal sac of the aedeagus is characteristic in lateral view, but well visible only when extruded ( Figs 25–27 View Figure ). However, since none of the previously studied specimens of I. jaljalense  shows a well visible extruded internal sac of aedeagus, the validity of this species requires revision.
