Description
Summary:Haploniscus angustus Lincoln, 1985 Haploniscus angustus Lincoln, 1985b: 676 –679, figs 11–12. — Kussakin 1988: 390–392, fig. 329.— Kavanagh 2009: 29. Material examined. BIOICE stn. 2579, RV Håkon Mosby, RP sled, 15 July 1993, 67°0575N. 24°4327W, 996 m, - 0.58°C, 1 specimen (IMNH 36862). BIOICE stn. 2856, RV Bjarni Saemundsson, RP sled, 29 August 1995, 62°2050N, 16°5930W, 2074 m, 2.34°C, 3 specimens (IMNH 36863); BIOICE stn. 2859, RV Bjarni Saemundsson, RP sled, 29 August 1995, 61°5022N, 16°5286W, 2270 m, 2.37°C, 1 specimen (IMNH 36864); BIOICE stn. 3659, RV Håkon Mosby, RP sled, 24 July 2004, 67°4761N, 19°3638W, 806 m, -0.53°C, 2 specimens (IMNH 36865). Remarks. Only females of H. angustus were found, which occurred on both sides of the GIF Ridge (Fig. 10 C). The species has earlier been reported from several stations in the northern part of the Rockall Trough and the Porcupine Sea-Bight (Lincoln 1985b; Kavanagh 2009). Svavarsson (1988) reported specimens of H. ingolfi from the Nordic Seas lacking a terminal process on the sixth article of antenna 2, which is one of the characteristics of H. ingolfi. Those specimens may possibly belong to the present species which does not have such process, rather than belonging to H. ingolfi.
