Remarks. Trichodromeus jaegeri was originally described based on several specimens from two localities in Gandaki Province, central Nepal. New faunistic data extends the previously known boundaries of the distribution of the species ( Fig. 47 ). The apical portion of the median lobe of some specimens ( Figs 41–42 ) is distinctly narrower than that in specimens from Gandaki Province (fig. 7 in Shavrin (2021)). It is here recorded from Karnali Province of Nepal for the first time.
