ItemDescription of a new species of rariphotic Parapercis (Perciformes: Pinguipedidae) from the Solomon Islands (American Museum novitates, no. 3978)(American Museum of Natural History., 2021-09-30) Sparks, John S.; Chaloux, Nicholas; Schelly, Robert C.; Gruber, David F.; Sparks, Tate S.; Phillips, Brennan T.A new species belonging to the pinguipedid genus Parapercis is described herein from a single specimen collected via a remotely operated vehicle (ROV) from rariphotic depths in the Western Province of the Solomon Islands. Parapercis rota, new species, is readily distinguished from all other congeners by a unique pigmentation pattern comprising four large, rounded, orangish-olive saddles dorsally on the flank, each with a distinct, large, dorsomedial white spot completely enclosed within the saddles, plus a fifth saddle on the caudal peduncle with only a small white dorsomedial dot; 10 discrete broad, dark orangish-olive oval vertical bars below the lateral midline; a single row of dark spots on the soft dorsal fin; caudal fin lined dorsally and ventrally with stripes of yellowish-olive pigmentation extending the length of the fin; and two prominent dark brown to black spots at the caudal-fin base. ROV-based collecting systems are a promising and relatively affordable technology for studying ichthyological diversity on deeper reef habitats, particularly those beyond the reach of technical SCUBA. The discovery and description of P. rota adds to the growing number of Parapercis species that are known to occur in mesophotic and deeper waters. ItemRevision of the Congo River Lamprologus Schilthuis, 1891 (Teleostei, Cichlidae), with descriptions of two new species. American Museum novitates ; no. 3451(New York, NY : American Museum of Natural History, 2004) Schelly, Robert C.; Stiassny, Melanie L. J.The Congo River Lamprologus are revised and two new species are described. Lamprologus teugelsi, n.sp., from Malebo Pool and the lower Congo River rapids, and L. tigripictilis, n.sp., from the lower Congo River rapids, are readily distinguished from the remaining Congo River Lamprologus based on counts, measurements, osteology, and color pattern. Monophyly of the Congo River Lamprologus species is tentatively accepted and a key to the group is provided. All available collection localities for re-identified Lamprologus material from the Congo River are plotted for each species. Maps of collection localities reveal large distributional voids, suggesting that Congo River lamprologine diversity remains incompletely sampled.
