Paralanceola anomala Barnard, 1930 (Figs 6 & 7) Paralanceola anomala Barnard, 1930: 398 –400, fig. 52. Hurley 1969: 33. Vinogradov et al. 1982: 47 –48, fig. 4. De Broyer & Jazdzewski 1993: 106. Type material The unique type of P. anomala is in the BMNH (1954.5.1.1.), on one microscope slide. Material examined The unique type, a male about 6 mm long, from the Pacific sector of the Antarctic [71 ° 41 S, 166 ° 47 W], (Terra Nova Stn. 282), 0–1000 m, 7 Jan. 1913: one microscope slide of dissected appendages. Diagnosis Based on Barnard’s (1930) description and on examination of remains of the type. Males reach lengths of at least 6 mm. Head without rostrum. Eyes minute, consisting of four ocelli with crystal cones. Antennae 1; callynophore conical, similar in length to peduncle; with two small terminal articles, the terminal one more than twice as long as the preceding one, narrowing distally, tipped with one seta. Antennae 2; length 2.5 –3.0x A 1; seven (or 8?)­articulate; peduncular article elongate, relatively enlarged; flagellum very long, whip­like, consisting of six, very slender, elongate articles, the first is the longest and the terminal one is relatively short with three short setae terminally. Mandibular palp; length third article 1.3 x articles 1 & 2 combined. Maxillae 1; palp with four, short, robust setae terminally and row of fine setae along inner margin; outer lobe with five robust setae, two slightly shorter than others. Maxillae 2; inner lobe with three, and outer lobe with four, relatively long, robust, dentate setae. Maxilliped; outer lobes with dentate inner margin; inner lobes slender, length about 0.5–0.7 x outer lobes. Pereopods 3 & 4 similar in length, slightly shorter than P 5 (> 0.8 x). Pereopod 6 similar in length to P 7; both about 0.9 x P 5. Pereopods 5–7 with retractile and hooded dactyls. Uropod 1; peduncle reaching just beyond limit of peduncle of U 2. Telson length about 0.7 x peduncle of U 3. Description of holotype Based on Barnards (1930) description and on ...
