Biology of the Antarctic Seas 78-80
“Colossendeis elephantis, new species Fig. 3
Material examined. Eltanin: 8-610 (one specimen (holotype), USNM 234696), 13-1146 (one specimen (paratype), USNM 234697).
Islas Orcadas: 575-81 (one specimen (paratype), USNM 234698).
Distribution. The early Eltanin and Islas Orcadas specimens were taken in the vicinity of the South Sandwich Islands in deep water: 8-610 in 2573-2684 m, and 575-81 in 2384-2402 in. The other Eltanin specimen (13-1146) was taken in the Antarctic sector (66°S) of the southeast Pacific Basin in 4789-4795 m.
Description. A moderately large species: leg span of holotype, about 280 millimeters. Trunk with rather long lateral processes separated by about their diameters. Trunk about 0.55-0.6 as long as proboscis which is widely inflated at midpoint and distally, with slight distal clowncurve. Ocular tubercle small, low, rounded, blind. Abdomen short, extending only little beyond tips of fourth lateral processes.
Palps long, robust, sixth and seventh segments long, distal 3 segments with eighth slightly shorter than subequal ninth and tenth. All armed with few tiny setules. Oviger robust, strigilis terminal segment with several rows of denticulate spines of equal size, without terminal spine forming subchela with terminal claw. Claw very narrow, well curved, little longer than segment diameter.
Legs slender, glabrous, femora the longest segments, tarsus about 0.3 longer than propodus, claw very slender, about 0.8 as long as propodus. Sex pores not seen.
Measurements (in millimeters): Holotype: trunk length, 13.1; trunk width (across second lateral processes), 9.8; proboscis length, 23.2; abdomen length, 3.0; third leg, three coxae, 12.1; femur, 34.0; tibia 1, 29.1; tibia 2, 24.4; tarsus, 19.5; propodus, 9.8; claw, 6.3.
Some measurements of the Islas Orcadas paratype, presumably a female: trunk length, 16.8; trunk width, 9.9; proboscis length, 27.2; abdomen length, 3.2.
Etymology. The name (Latin: elephant's, of an elephant, or elephantine) refers to the long broad elephantine proboscis.
Remarks. This species has sonic similarities to C. colossea in its broadly inflated proboscis, slender legs, and long, thick palps with their distal 3 segments almost equal in length. It differs from that species in having a slightly downcurved proboscis which is not present in C. colossea. It also has a shorter abdomen, a small blind ocular tubercle, and much longer propodal claws. Its grossly swollen proboscis is not found in any other Antarctic species except for the much shorter and spinose proboscis of C. avidus, and perhaps that of C. australis.” (Child 1995b, p.78-80)
