A lectotype is designated for the Tibetan species Deronectes emmerichi Falkenström, 1936 (Currently Boreonectes emmerichi (Falkenström)), and its habitus, as well as the median lobe and parameres of its aedeagus, are figured along with additional comparative material. Material of B. emmerichi from Sikkim (BMNH) represents the first record of a Boreonectes Angus, 2010 species from India. The karyotype of B. emmerichi is described as having 26 pairs of autosomes plus sex chromosomes which are X0 (♂), XX (♀). The karyotype is most like that of B. macedonicus (Géuorguiev, 1959), but with slight differences. Additional chromosomal information is given for B. griseostriatus griseostriatus (De Geer, 1774) in the French Alps, B. g. strandi (Brinck, 1943) on the Kola Peninsula, B. multilineatus (Falkenström, 1922) in the Pyrenees and B. ibericus (Dutton & Angus, 2007) in the Spanish Picos de Europa.
