Calanoid Copepods from the Caribbean Sea and Gulf of Mexico. 2. New Species and New Records from Plankton Samples

Bulletin of Marine Science -Miami- (Impact Factor: 1.31). 05/1970; 20(2):472-546.

ABSTRACT Twenty-eight new species of calanoid copepods and the male of Bathypontia minor (Wolfenden, 1906) are described from specimens found in vertically collected samples of plankton obtained in the Caribbean Sea and Gulf of Mexico. Diagnoses or systematic remarks are presented for 16 other species of calanoid copepods. Fifty-eight species of calanoid copepods not previously known from the Caribbean Sea and Gulf of Mexico are reported. A key is included for the identification of the species of Spinocalanus.

    • "Here and below the most primitive state of characters described for the genus are given; ii) 15 setae on maxillule praecoxal arthrite in Monacilla (Schulz 1989), vs. fewer in other spinocalanids; iii) 6 setae on maxillule coxal endite in Spinocalanus (Damkaer 1975; Brodsky et al. 1983; Schulz 1989), vs. fewer in other spinocalanids; iv) 6 setae on maxillule distal basal endite in Teneriforma (Schulz 1989), vs. fewer in other spinocalanids; v) 16 setae on endopod and 11 setae on exopod of maxillule in Monacilla, Spinocalanus, Mimocalanus (but 23 on endopod in M. crassus Park, 1970); exopod setation of this type also in Mospicalanus (Damkaer 1975; Schulz 1989, 1996), vs. fewer in other spinocalanids; vi) maxilla with 9 setae (2+7) on endopod fused to distal basal endite in Monacilla and Spinocalanus (Schulz 1989), vs. fewer in other spinocalanids; vii) praecoxal endites of maxilliped syncoxa with 1, 2, 3 setae in Monacilla and Spinocalanus (Schulz 1989), vs. fewer in other spinocalanids; viii) coxal endite of maxilliped syncoxa with 4 setae in Monacilla and Mimocalanus (Brodsky et al. 1983; Schulz 1989), vs. fewer in other spinocalanids. Typically, pelagic Spinocalanidae share some primitive characters with more derived benthopelagic spinocalanid genera: i) the primitive type of antenna exopod setation 1, 1–1–1, 1, 1, 1, 1, 1, and 3 setae, is shared by pelagic Monacilla, Spinocalanus, and Teneriforma and the benthopelagic genus Kunihulsea (Park 1970; Schulz 1989, 2004); ii) the most primitive condition in the armature of the proximal basal endite of maxillule (4 setae) is found in the pelagic genera Monacilla, Spinocalanus, Mimocalanus, and Mospicalanus as well as the benthopelagic Methanocalanus (Schulz 1989, 1996; Park 1970; Ivanenko et al. 2007); iii) the most primitive armature of the proximal praecoxal endite of maxilla (7 setae) is shared by the pelagic Monacilla and the benthopelagic genus Methanocalanus (Schulz 1989; Ivanenko et al. 2007).

    ABSTRACT: Two species of a new spinocalanoidean genus, Caudacalanus, are described from female specimens collected during the German expeditions ANDEEP I-II in 2002 and DIVA-1 in 2000 at abyssal depths above the seabed in the Southern Ocean and tropical waters of the South Atlantic. Segmentation and setation of swimming legs of the new genus are typi- cal of the superfamily Spinocalanoidea. Caudacalanus gen. nov. shares the derived morphology of the oral parts and P1 basis and endopod with a monophyletic group of genera, viz. Arctokonstantinus, Foxtonia and Sognocalanus. Arctokon- stantinidae is available for this lineage. The new genus differs from other spinocalanoideans by strong asymmetry of the caudal rami, with the right ramus nearly twice as long and wide as the left; setation of maxillule exopod reduced to 0-1 seta; maxilla basis lacking any setae; and maxilliped basis with 1 seta and endopod reduced to 3 segments.

    ABSTRACT: On the SOND Cruise of R.R.S. 'Discovery' in 1965 a day and a night series of horizontal hauls were made with a modified Indian Ocean Standard Net (N113 H) fitted with a catch dividing bucket (C.D.B.). The hauls were of 1 h duration, made at approximately 50 m depth intervals from 960 to 40 m, at a position off Fuerteventura in the Canary Islands. This paper is one of a series by various authors on the vertical distributions of the animal groups sampled (Angel, 1969; Clarke, 1969 a; Baker, 1970; Badcock, 1970; Foxton, 1970a, b). Details of the cruise and of the hydrology of the area are given by Currie, Boden & Kampa (1969), and Foxton (1969) gave details of the sampling methods.
