FLABELLIFERA • L1MNOR11DAE 193 RECORDS Flamefish Apogon maculatus: Puerto Rico. Belted cardinalfish Ap- ogon townsendi: Puerto Rico. Renocila waldneri Williams and Williams, 1980 Figure 85D DIAGNOSIS Ovigerous 9 15.3-19.3 mm, 6 5.0-10.8 mm. Posteroventral angle of pereonite 5 moderately produced, of pereonites 6-7 more strongly produced, that of pereonite 7 overlapping pleonites 1 and 2. Pereopods 1-3 without swelling on dactyli. Pereopods 6 and 7 subequal in length. Uropodal exopod slightly longer than endopod. Pleotelson basally wider than long; posterior margin broadly and evenly rounded. Color: dorsal surface of body uniform brown; appendages yellowish brown. Attached to dorsum of body close to dorsal fin. RECORDS Harlequin bass Serranus tigrinus: Dominican Republic. Family Limnoriidae Harger, 1879 DIAGNOSIS Body ovate in cross section, often becoming more setose posteri orly. Cephalon subspherical, freely articulating with pereonite 1; eyes lateral. Antennules and antennae well separated at bases. Mandible with strong in cisor; lacking molar and well-defined lacinia mobilis, but with species- distinctive lacinioid bristle or seta; palp usually of three articles. Maxillipe- dal palp of five articles; endite well developed. Coxae present on pereonites 2-7. Pleon consisting of five free pleonites plus pleotelson; latter subcircular, set obliquely to axis of body, usually with anterolateral crests. Uropod with strong protopod inserted ventrolaterally. Key to genera of Limnoriidae 1. Uropodal rami very unequal 2 Uropodal rami subequal Paralimnoria 2. Mandibular incisors possessing rasp and file Limnoria Mandibular incisors lacking rasp and file Phycolimnoria
194 FLABELLIFERA • LIMNORIIDAE REMARKS This family includes a number of species that are of considerable economic importance. Given that species of Limnoria are wood borers, wooden structures such as wharf pilings that are immersed in sea water and even in water of reduced salinity are vulnerable to attack by these gribbles. Prolonged exposure can lead to weakening and eventual collapse of these structures (see Ray, 1959). Even creosote-treated wood is not fully protected; Limnoria tuberculata will bore into such wood to where the creosote has not penetrated. The isopods rasp at the wood fibres with the rasp and file structures of the mandibles, usually following the grain of the wood. With this boring activity, saprophytic fungi and bacteria invade the wood and assist in the breakdown process. Limnoria lack cellulase-secreting microflora in their gut, but proba bly secrete a cellulase themselves (Boyle and Mitchell, 1978). It is also prob able that the fungi and bacteria, the latter often densely aggregated on the setae of the isopod, form part of the animals' diet. In the natural environ ment, Limnoria perform an important role in the breakdown of dead wood, especially in mangrove areas. Sexual dimorphism of the pleotelson does occur in some species. This as pect of the morphology, however, has hardly been investigated. Limnoria Leach, 1814 DIAGNOSIS Antennular flagellum of four articles. Antennal flagellum of three to five articles. Incisor of right mandible equipped with filelike struc ture on upper surface; incisor of left mandible with rasplike structure. Rami of pleopod 5 lacking marginal setae. Uropodal exopod much shorter than endopod, bearing terminal claw. Pleotelson smooth, or variously ornamented with tubercles and ridges. Limnoria indica Becker and Kampf, 1958 Figure 86A,B DIAGNOSIS 6 3.0 mm, ovigerous 9 3.0 mm. Pleonite 5 with submedian pair of strong rounded ridges, converging slightly posteriorly. Pleotelson basally with two pairs of submedian tubercles and pair of lateral tubercles. RECORDS Cozumel, Mexico; Man o'War Cay, Belize. India; Hong Kong; Philippines; east coast of Australia.
