Ríos, Rubén & Duffy, J. Emmett, 2007, A review of the sponge‑dwelling snapping shrimp from Carrie Bow Cay, Belize, with description of Zuzalpheus, new genus, and six new species (Crustacea: Decapoda: Alpheidae), Zootaxa 1602 (1), pp. 1-89 : 7

Genus Zuzalpheus n. gen.

Synalpheus, Coutière 1908 and 1909 (in part, only species included in his Group Laevimanus)

Type species. Zuzalpheus kensleyi , n. sp., here designated.

Diagnosis. Carapace smooth, projected into ocular hoods covering eyes; anterior edge usually with a trispinose appearance due to acute rostrum; cardiac notch present. Rostrum, generally equal to or slightly overreaching ocular hoods. Scaphocerite with or without blade; when present, always shorter than adjacent lateral spine. Basal segment of antennular peduncle usually without tooth on mesioventral edge. Sixth abdominal somite without articulated plate. Telson lacking anal tubercles; distal margin broadly convex or reduced to narrow space between distal marginal spines. Third maxilliped slender, not forming operculum covering remaining mouthparts. First pair of pereopods unequal; major first pereopod, smooth, usually with superodistal edge of palm forming protuberance overhanging base of dactyl, this latter with massive molar-like tooth accommodated in cavity on internal edge of base of fixed finger. Minor first pereopod with distinct brush of dense distally curved setae on extensor surface of dactyl. Second pereopod with carpus 4 or 5-segmented. Third pereopods, with merus usually lacking spines on ventral margin; always with distinct mesial lamella on coxa. Third to fifth pereopods with dactyl biunguiculate. Epipods absent from all pereopods. Second to fifth pleopods in both sexes with only appendix interna. Lateral margin of uropodal exopods with one to several fixed teeth.

Etymology. From the Mayan ‘ Zuz ’ (brush), alluding to the synapomorphic brush of setae on the dactyl of the minor first chela, and the ending ‘ alpheus ’ common in the names of genera in the family Alpheidae . Gen- der, masculine.
