A New Species, Caelorinchus sheni, and 19 New Records of Grenadiers (Pisces: Gadiformes: Macrouridae) from Taiwan
Mei-Luen Chiou, Kwang-Tsao Shao and Tomio Iwamoto (2004) This paper reports 1 new species, Caelorinchus sheni sp. nov., and 19 new records of grenadiers (Macrouridae) from Taiwan which were collected by bottom trawler and landed at the fishing harbors of Tashi and Nanfangao in northeastern Taiwan and Tungkang in southwestern Taiwan. The diagnostic characters for C. sheni sp. nov. are the prominent banding pattern on the body, the large mouth with conical teeth in a relatively long band, and the anterolateral snout margin incompletely supported by bone. Caelorinchus sheni is similar to C. quadricristatus and C. celaenostomus. The 3 species differ in details of the dentition, the shape of the preopercle and subopercle, banding patterns, and proportions. The species newly recorded in Taiwan are Bathygadus antrodes, B. garretti, B. nipponicus, Gadomus colletti, Caelorinchus asteroides, C. longissimus, C. productus, Hymenocephalus lethonemus, Hymenogadus gracilis, Kumba japonica, Lucigadus lucifer, Nezumia condylura, Pseudocetonurus septifer, Ventrifossa atherodon, V. divergens, V. longibarbata, V. macroptera, V. rhipidodorsalis, and V. saikaiensis. In addition to the description of the new species and 19 new records, color photos of each species and a diagnostic key for all 40 species in the family Macrouridae are provided.
