Alpheus praecox Herrick 1888: 34   ; De Grave & Anker 2010: 53.

Material examined. USA: 1 male, 4 ov. females, 1 female, OUMNH. ZC.2012-07-073, Florida Keys, Bahia Honda, Seven Mile Bridge near Marathon, ocean side, in Spheciospongia vesparium   (among other sponges, e.g., Ircinia sp.   ), 0.5 m, coll. A. Anker, A.L. Rhyne, 19.04.2004 [fcn 04-002A]; 12 males, 7 ov. females, 3 juveniles, MNHN-IU-2010-4151, same collection data [fcn 04-002B].

Description. For description and illustrations see Coutière (1909) and Dardeau (1984); see also Ríos & Duffy (2007).

Size range. Males, 3.0– 4.4 mm cl; females, 3.6–4.5 mm cl.

Colour in life. Semitransparent with pinkish tinge; major chela fingers darker ( Ríos & Duffy 2007).

Type locality. Curaçao   .

Distribution. Western Atlantic: Florida [Alligator Harbor, Crystal River, Florida Bay, Florida Keys etc.]; Gulf of Mexico; Bahamas [Eleuthera, Cay Sal Bank]; Caribbean Sea: Lesser Antilles, Virgin Islands, Haiti, Cuba, Jamaica, Yucatan, Panama, etc. ( Coutière 1909; Dardeau 1984; Ríos & Duffy 2007; Macdonald et al. 2009; present study; see map in Fig. 52 View FIGURE 52 ).

Ecology. Shallow reef flats or seagrass flats with rubble and sponges; depth range 1–20 m; obligate sponge symbiont and apparently a specialist of the loggerhead sponge Spheciospongia vesparium   ; usually in heterosexual pairs.

Remarks. Synalpheus pectiniger   can be distinguished from all other species of the S. gambarelloides   group by the shape of the major chela, especially the very strong, sharp, anterodorsally directed distal tooth, and the pollex being much shorter than the dactylus ( Coutière 1909; Dardeau 1984). The only other western Atlantic species with the pollex much shorter than the dactylus is S. disparodigitus Armstrong, 1949   , in which, however, the distal tooth is a bulbous tubercle with a small, anteriorly directed point. The two species also differ in the shape of the orbital teeth and rostrum, as well as the armature of the fingertips of the minor cheliped and the number of lateral teeth on the uropodal exopod ( Armstrong 1949). These important differences suggest that S. disparodigitus   and S. pectinger   are not closely related and that a similar configuration of the major chela fingers evolved at least twice in the S. gambarelloides   group. This is also supported by the molecular data showing a distant relationship between S. pectiniger   and S. occidentalis Coutière, 1909   , an eastern Pacific species that appears to be morphologically close to S. disparodigitus   ( Morrison et al. 2004; Hultgren & Duffy 2011).

The taxonomic status of Alpheus praecox Herrick, 1888   was recently clarified by De Grave & Anker (2010), who after a meticulous study of Herrick’s and Coutière’s descriptions and the associated collecting data (including description of host sponges) found it to be a senior synonym of S. pectiniger   . However, for the sake of taxonomic stability, A. praecox   was designated a nomen oblitum and placed in the synonymy of S. pectiniger   .
