| Related Species | Alpheus alpheopsides Coutière, 1905 [IWP]; A. paralpheopsides Coutière, 1905 [IWP]; A. aff. paracrinitus (Anker, pers. obs.) [IWP]; A. bengalensis Coutière, 1905 [IWP]; A. mitis Dana, 1852 [IWP]; A. paracrinitus Miers, 1881 [EA-CA-WA]; A. "subparacrinitus" Anker et al., in prep. [WA]; A. "coeruleocinctus" Anker et al., in prep. [EA]; A. fasciatus Lockington, 1878 [EP]; A. rostratus Kim and Abele, 1988 [EP]; A. "pararostratus" Anker et al., in prep. [EA]; A. "geminirostratus" Anker et al., in prep. [WA]. Alpheus tenuipes is extremely difficult to separate from A. paralpheopsides. A. bengalensis and A. aff. paracrinitus; it differs from those species mostly by the more slender appendages (including the major chela, see De Man, 1911). It differs from A. alpheopsides by the presence of small orbito-rostral process and longer, more slender rostrum (see Coutière, 1905). All Atlantic and eastern Pacific species, as well as A. aff. rostratus can be distiguished by color patterns and subtle morpholgical features, such as the somewhat more slender major cheliped. |
| Size | Body length to about 13 mm (De Man, 1911). |
