NUMBER 543 45 *55. Urocaridella vestigialis, new species FIGURE 17 DIAGNOSIS.—Carapace with apex of branchiostegal spine removed from margin by about length of spine (Figure 17a); 3rd abdominal somite with moderately convex dorsal profile (Figure \7b); 5th abdominal pleuron sharply acute at posteroventral angle (Figure 17 b); telson with posterior margin acutely triangular but without distinct endpiece (Figure \7d); antennal scale fully 3 times as long as wide (Figure 17g); mandibles with vestigial, socketed palps, better formed on right side than left (Figure \7h-j); 1st pereopod with fingers about as long as palm (Figure 17r), chela shorter than carpus (Figure \7q); 2nd pereopod with fingers about as long as palm (Figure 175), palm shorter than carpus (Figure 17s); 3rd pereopod with propodus 4 times as long as dactyl (Figure 17M); 4th pereopod with propodus 4*/2 times as long as dactyl (Figure 17w); 5th pereopod with propodus more than 5 times as long as dactyl (Figure 17y); postorbital carapace length of female 6.4 mm. MATERIAL.—INDONESIA. Selat Butung, Celebes: sta 5642; 4° 31'40"S, 122°49'42"E; 68 m; gray mud; 14 Dec 1909 (1100-1117); 12' Agassiz beam trawl: 1 female [6.4], holotype (USNM 252657). TYPE LOCALITY.—Same as above. RANGE.—Known only from the type locality. REMARKS.—As indicated in the key, both U. antonbrunii and U. vestigialis differ from the type species, U. urocaridella, in lacking a narrowly triangular posterior endpiece on the telson; in lacking a well-developed palp on the mandible; in having the fingers of the first pereopod about as long as, rather than longer than, the palm, and the chela shorter than, rather than twice as long as the carpus; in having the fingers of the second pereopod about as long as, rather than distinctly longer than the palm, and the palm no longer than the carpus; and in having the propodus of the walking legs less than four, rather than four to to more than five times as long as the dactyl. Urocaridella vestigialis differs from U. antonbrunii in having the branchiostegal spine less far removed from the carapace margin; in having the dorsal profile of the third abdominal somite simply convex rather than subrectangular; in having the pleuron of the fifth abdominal somite sharply acute rather than rounded posteroventrally; and in having the mandibular palp vestigial rather than completely absent. ETYMOLOGY.—Derived from the Latin vestigium (trace or vestige), in reference to the vestigial mandibular palp. Pontoniinae Kingsley, 1878:64. •PONTONIINAE Kingsley, 1878 DIAGNOSIS.—Telson typically armed with 3 pairs of posterior spines. RANGE.—All tropical and subtropical, occasionally temperate, seas, especially on tropical reefs, often in association with other reef organisms; littoral to 1820 meters. REMARKS.—Although only about half of the more than 60 currently recognized pontoniine genera are here reported from the Philippine-Indonesian region, that apparent representation is certain to increase as the rich coral-reef fauna of the area is further investigated; several of the genera not yet known from the region occur in neighboring waters, especially in the Indian Ocean and on the Great Barrier Reef of Australia. For that reason, we have rashly attempted the following checklist of all of the genera and species and key to all of the genera known at least through 1989 in the hope that they may be helpful to the study of an incompletely known area and that the subsequent correction of their shortcomings may eventually produce a better product than might otherwise be probable.
