Caridina longirostris H. Milne Edwards, 1837 described from specimens supposedly from La Macta River near Oran, Algeria, is an emblematic species of the {\textquoteleft}C. nilotica complex{\textquoteright}. Until now this species was thought to have a wide distribution in the Indo-Pacific region. Recently, numerous specimens identified as C. longirostris were collected from various Indo-West Pacific localities. In the context of integrative taxonomy, both old and newly collected specimens were morphologically and genetically studied. Four species allied to C. longirostris are here identified: C. appendiculata Jalihal \& Shenoy, 1998, C. brevidactyla Roux, 1920, C. gracilipes De Man, 1892 and C. meridionalis Roux, 1926. Detailed re-descriptions of these four species are given as well as their geographical and ecological distributions. Caridina nilotica var. brevidactyla is revalidated as the species C. brevidactyla, and C. coulaborensis Richard\&Clark, 2014, C. fritzi Richard \& Clark, 2014 and C. solamulieres Richard \& Clark, 2014 are considered junior synonyms of C. meridionalis. The position of these species in the troublesome {\textquoteleft}C. nilotica complex{\textquoteright} is clarified and some species are synonymised. A key is provided to facilitate identification.
