Abstract. Five species ofthe genus Nisotra Baly are known from China. Nisotra
xinjiangana, n. sp., is described, and Nisotra dohertyi Maulik and Nisotra nigripes
Jacoby are newly recorded from China. A key to the known Chinese species is given.
The habitus of the new species and the aedeagus and the spermatheca of all species
are illustrated.
Key Words: Alticinae, Nisotra, new species, new record, China
The genus Nisotra was proposed by Nisotra Baly, 1864
Baly in 1864, with the type species Haltica Nisotra Baly 1864: 437 (type species:
gemella Erichson. At present, more than Haltica gemella Erichson, 1834, by
70world speciesare known. Amongthem,
original designation).
