Caridina jeani, a replacement name for Caridina typus var. brevirostris J. Roux, 1911 from Eastern Indonesia (Crustacea: Decapoda: Atyidae)

Caridina typus var. brevirostris Roux is shown to be specifically different from Caridina typus H. Milne Edwards, 1837. A new name Caridina jeani is thus proposed for the species as the name Caridina brevirostris is preoccupied by C. brevirostris Stimpson, 1860. The species is re-described and illustrated in detail based on syntypic specimens. It differs markedly from Caridina typus by possessing sexual dimorphism on the third and fourth pereiopods. A lectotype is designated.
