Description. See Pocock (1890) for original description (diagnosis), and Crosnier & Forest (1966), Banner & Banner (1982) and Abele & Kim (1986) for illustrations, and Anker et al. (2006) for a colour photograph (see also Fig. 11 View FIGURE 11 A, B).

Distribution. Pantropical (but see below). Amphi-Atlantic: São Tomé & Príncipe; Equatorial Guinea: Annobon Island; Ascension Island; throughout Caribbean Sea; Florida; Brazil: Fernando de Noronha, Atol das Rocas , Trindade & Martin Vaz Archipelago ( Christoffersen 1998 and references therein; present study). Indo- Pacific: Madagascar to Hawaii, French Polynesia and Clipperton Island ( Banner & Banner 1982).

Ecology. Coral reefs and rocky reefs with abundance of dead corals and coralline algae; dwelling deep in crevices of coral rocks and clumps of coralline algae; intertidal to about 30 m.

Remarks. Metalpheus rostratipes is a crevice-dwelling snapping shrimp found mainly in rock-algal and coralrock substrates on offshore reefs and oceanic islands. The species was previously known from Brazil based on records from Fernando de Noronha and is now recorded from two other oceanic islands, Atol das Rocas and Trindade Island. It is presently not known from the Brazilian continental coast.

Metalpheus rostratipes View in CoL is currently regarded as a widely distributed pantropical species ( Crosnier & Forest 1966; Banner & Banner 1982). A comparison of several male specimens from Trindade Island (western Atlantic), São Tomé Island (eastern Atlantic) and Line Islands (western Pacific) did not yield any substantial morphological differences. Their colour patterns are also very similar or nearly identical (A. Anker, pers. obs.). As for other pantropical species or species complexes, a comprehensive genetic analysis (COI or 16S genes) is desirable for M. rostratipes View in CoL , in order to evaluate the genetic differences between the Atlantic and Indo-West Pacific populations.

Anker et al. (2006) showed, after performing a cladistics analysis of all alpheid genera known at that time, that Metalpheus View in CoL may be nested (together with two other genera) within Alpheus View in CoL , thus making the latter genus paraphyletic. However, generic rearrangements in Alpheus View in CoL and related genera (including Metalpheus View in CoL ) must await a more comprehensive phylogenetic analysis, including molecular datasets.
