Description of three new muricids (Gastropoda: Muricidae: Muricinae) from the Philippines and Fiji

摘要

Three new species are described from the Philippines and Fiji, one in the genus Chicomurex Arakawa, 1964 and two in Chicoreus (Triplex) Perry, 1911. Chicomurex excelsus new species from the Philippines is compared with C. gloriosus (Shikama, 1977), C. pseudosuperbus Houart, Moe, and Chen, 2015, and C. venustulus (Rehder and Wilson, 1975), species that are or were confused with the new species. Chicoreus (Triplex) kaitomoei new species from Fiji is compared with C. aculeatus (Lamarck, 1822), C. rossiteri (Crosse, 1872), C. nohilis Shikama, 1977, C. njukyuensis Shikama, 1978, and C. cloven Houart, 1985; two of these were confused with the new species by recent authors and the others have a few similar shell characters. Chicoreus (Triplex) aquilus new species from Fiji is compared with C. ruhescens (Broderip, 1833), C. strigatus (Reeve, 1849), C. paini Houart, 1983, and C. dodongi Houart, 1995, species with an approximately similar size, a similarly narrow shell, high spire, moderately long siphonal canal, and small aperture.
