Crepis longipes Jullien 1882

Abstract

Crepis longipes Jullien, 1882 (Figs 18–22, Table 6) Crepis longipes Jullien, 1882: 522, pl. 17, figs 60, 61; Prenant & Bobin 1966: 366, fig. 119; d’Hondt 1973 a: 367; 1974: 29; Reverter-Gil et al. 2011: 2, figs 1-4; Souto et al. 2014: 136, fig. 3 C, D. Material examined. MNCN 25.03 / 3932, locality DW 110; MNHN IB- 2013 - 622, locality DW 117. Remarks. Reverter-Gil et al. (2011) recently redescribed type and other material of Crepis longipes from the Iberian continental shelf. Although the authors stated that one of the Travailleur stations from which Jullien (1882) originally recorded the species was Galicia Bank, this was a mistake owing to a wrong interpretation of the geographic position. During the Travailleur campaign the longitude was referenced to the Paris meridian, which nowadays makes it necessary to correct the original reading to the Greenwich meridian (Ryland 1969). After corrections, that station is situated on the continental slope of northern Iberia. Nevertheless, we are able to demonstrate here that C. longipes does, indeed, occur on Galicia Bank, which marks the first record of this species off the continental shelf. SD, standard deviation; N, number of measurements Souto et al. (2014) described the ovicell and operculum of C. longipes for the first time; both characters were also observed in the specimens from Galicia Bank (Figs 18, 19, 22), and are identical with the previously recorded material. Ovicells are terminal, the ooecium being formed by a distal kenozooid that is concealed from frontal view, and which distally buds the caudal part of the next autozooid in a row. Several specimens were found at four Galicia Bank localities ranging from 770 to 860 m depth. The colonies mainly encrust coral skeletons but also rocks, while one colony was found on a piece of slightly lithified foraminiferal sand.Published as part of Souto, Javier, Berning, Björn & Ostrovsky, Andrew N., 2016, Systematics and diversity of deep-water Cheilostomata (Bryozoa) from Galicia Bank (NE Atlantic), pp. 401-459 in Zootaxa 4067 (4) on pages 412-413, DOI: 10.11646/zootaxa.4067.4.1, http://zenodo.org/record/25794
