| Summary: | Asterocheres intermedius (Hansen, 1923) Ascomyzon intermedium Hansen 1923: 6. Asterocheres intermedius: Stock 1966b: 152; Johnsson 1998: 91. Material examined. Holotype Ψ (ZMUC. CRU-6873/8357) collected during the “Danish Ingolf Expedition” in Davis Strait, Station 25 (63º30΄N, 54º25΄W), at 582 fathoms (ca. 1.06 km). Hosts. Unknown. Distribution. Atlantic Ocean (Hansen 1923). Remarks. Hansen (1923) omitted some taxonomically important appendages, such as the mandible and fifth legs (the latter lost in the type specimen), in his description of A. intermedius. Unfortunately, this species has not been recorded again, and only the antennule and antenna could be observed in the damaged, dissected holotype. Our observations of the pre-oral appendages differed from the original description as follows: 1) the antennule, despite being cleanly broken in half in the holotype, consists of 21 rather than 20 free segments; and 2) the endopod of the antenna is comprised of 3 instead of 2 segments. Despite these ... : Published as part of Bandera, Eugenia & Conradi, Mercedes, 2009, Redescription of Asterocheres suberitis Giesbrecht, 1897 and A. tenerus (Hansen, 1923) (Copepoda: Siphonostomatoida), including notes on A. abyssi (Hansen, 1923) and A. intermedius (Hansen, 1923), pp. 41-52 in Zootaxa 1980 on page 43, DOI: 10.5281/zenodo.185273 ... |
