Kim, Il-Hoi & Boxshall, Geoff A., 2021, Copepods (Cyclopoida) associated with ascidian hosts: Ascidicolidae, Buproridae, Botryllophilidae, and Enteropsidae, with descriptions of 84 new species, Zootaxa 1, pp. 1-286 : 42

Buprorides gen. nov.

Diagnosis (female). Cephalosome depressed, subcircular, well-defined from trunk somites by constriction. Urosome wider than long, with small rounded abdomen; caudal rami absent. Rostrum present. Antennule 5-segmented; first segment with 2 setae. Antenna 3-segmented, with 1, 4, and 6 setae on first to third segments, respectively. Labrum broad. Mandible consisting of coxa and 1-segmented palp; coxa with well-developed gnathobase; palp armed with 3 setae distally. Maxillule bilobed; inner lobe (precoxa) with spinulose spines on medial margin; outer lobe (palp) narrower than inner lobe, armed with 4 setae. Maxilla consisting of syncoxa and allobasis; syncoxa broad, with single large mediodistal endite tipped with 2 elements; allobasis with several setae. Maxilliped plate-like, unarmed. Legs 1-4 biramous with 2-segmented rami, armed only with setae; coxa lacking inner seta; intercoxal sclerite not discernible. Basis of leg 1 lacking inner distal element. Leg 5 expanded, lobate, extending over posterior margin of abdomen, armed with 5 naked setae distally.

Type species. Buprçrẚdes trẚlçbatus gen. et sp. nov. by original designation.

Etymology. The new genus is named after Buprçrus, the type genus of the family, and the suffix - ẚdes. Gender masculine.

Remarks. In all three species of Buprçrus, the maxilliped is armed with 4 setae and legs 1-4 have single-segmented endopods. Buprçrẚdes gen. nov. can be distinguished from Buprçrus, because the maxilliped is unarmed and legs 1-4 have 2-segmented endopods. There are other notable differences between the genera, such as, the possession of 3 setae on the mandibular palp in Buprçrẚdes gen. nov. compared with 1 or 2 setae in Buprçrus, and the presence of 6 slender setae on the terminal segment of the antenna rather than 5 setae (some spiniform) in BuprçrusK

The type species of Buprçrẚdes gen. nov. and Buprçrus nçrdgaardẚ are associated with compound ascidians, but the other two species of Buprçrus are associated with solitary ascidians.
