Salmoneus serratidigitus (Coutière, 1896)

Jousseaumea latirostris Coutière, 1896:382 [type locality: Red Sea].

Jousseaumea serratidigitus Coutière, 1896:382 [type locality: Red Sea].

Jousseaumea Sibogae De Man, 1910:303 [type locality: Banda Sea south of Kepulauan Lucipara, Indonesia; reef].

Salmoneus sibogae.—D.M. and A.H. Banner, 1979:239.

Salmoneus serratidigitus.—D.M. and A.H. Banner, 1981:58, figs. 7, 8.—Wicksten, 1983:40.

DIAGNOSIS.—Rostrum rather narrowly acute, overreaching 2nd antennular segment, unarmed ventrally, not carinate dorsally; carapace with orbital teeth horizontal, not upturned, reaching fully as far as midlength of 1st antennular segment, without dorsolateral crests; telson with posterior margin broadly emarginate or with narrow, U-shaped notch; antennal scale reaching level of distal end of antennular peduncle; major chela with movable finger not noticeably overreaching fixed finger, bearing 10–16 teeth on opposable margin; 3rd pereopod with dactyl simple, about as long as propodus; maximum carapace length to base of rostrum about 6 mm.

RANGE.—Red Sea, eastern Africa, Madagascar, Aldabra, Seychelles, Philippines, Indonesia, and Baja California, Mexico; shallow water. Just when the passage of time begins to cast doubt on the documentation of the record of the occurrence of six specimens of S. serratidigitus in the Gulf of California (Coutière, 1899:463, 544, and D.M. and A.H. Banner, 1981:65), because of the apparent absence of the species anywhere in the intervening Pacific Ocean and the presence of a related species (S. mauiensis) in Hawaii, Wicksten (1983:40) records another specimen from Cabo San Lucas. Such are the happenings that contradict the apocryphal boredom of taxonomic research!

Homaralphaeus Bate, 1876:378 [nomen nudum].

Homaralpheus Bate, 1888:539 [type species, selected by Holthuis, 1955:93: Alpheus minus Say, 1818:245; gender, masculine].

Synalpheus Bate, 1888:572 [type species, by monotypy: Synalpheus falcatus Bate, 1888:574 (= Alpheus Comatularum Haswell, 1882:762); gender: masculine].

Alpheinus Borradaile, 1899:415 [type species, by monotypy: Alpheinus tridens Borradaile, 1899:415; gender: masculine].

DIAGNOSIS.—Rostrum acute in lateral aspect; carapace without high carina throughout length of dorsal midline; abdomen without triangular flap articulated at posterolateral angle of 6th somite; telson not terminating posteriorly in triangular tooth; eyes concealed from dorsal view; mandible with palp and molar process; 3rd maxilliped not unusually broadened to form partial operculum over other mouthparts; 1st pereopods dissimilar and unequal, carried extended with movable finger dorsal or lateral, not ventral, major chela usually with molar-like tooth on movable finger, 2nd pereopod with fingers about as long as palm, carpus with 4 or 5 articles; pereopods without strap-like epipods on any pair; no appendix masculina on 2nd pleopod of male.

RANGE.—Virtually all tropical and subtropical and some temperate seas; intertidal to at least 250 meters.
