This study describes a new species of Choniomyzon copepod obtained from a longlegged spiny lobster in Taiwan, named Choniomyzon taiwanensis n. sp. The new species is characterized by distinctive morphological features and host preference.
Simple Summary This study reports an undescribed species of the Choniomyzon copepod obtained from a longlegged spiny lobster Panulirus longipes longipes (Milne-Edwards, 1868), collected from Hualien Port, Eastern Taiwan. We illustrated morphological features of the specimen to determine its taxonomic identification. The new species reported here is the first record of Choniomyzon species from spiny lobster in Taiwanese waters. Choniomyzon taiwanensis n. sp. is described based on specimens collected from examining external egg masses of spiny lobster Panulirus longipes longipes (Milne-Edwards, 1868), obtained from Hualien, Taiwan. The new species differs from its congeners in possessing the following characteristics: (1) small prosome (about 0.84 mm); (2) armature of antennule being 1, 1, 2, 2, 1, 1, 1, 2, 1, 1+1 (aesthetasc), 4, 6+1 (aesthetasc); (3) five-segmented antenna; (4) second segment of antenna bearing 1 inner seta; (5) two-segmented maxilla. Based on the evidence of distinctive morphological features and host preference, Choniomyzon taiwanensis n. sp. is a new species. Until now, four species of Choniomyzon have been known living on decapods, and the new species reported here is the first record of Choniomyzon species from spiny lobster in Taiwanese waters.
