Lebbeus acudactylus new species Figs. 4 D, 7–9 Type Material: Holotype female, postorbital carapace length 9.6 mm; with bopyrid parasite. Aleutian Islands, Alaska (51.86 ° N, 174.92 °W), trawl, 155 m. 13 June 2000. K.P. Maslenikov collector. National Museum of Natural History, Smithsonian Institution, USNM 1092260. Also allotype, 9.0 mm, with bopyrid parasite, Gulf of Alaska (56.12 ° N, 157.76 °W), trawl, 166 m. 12 June 2005. K.P. Maslenikov, collector, USNM 1092261. Paratype female, 7.1 mm, Aleutian Islands, Alaska (52.28 °N, 174.76 °W), trawl, 163 m. 15 June 2000. K.P. Maslenikov collector. California Academy of Sciences (CASIZ 174053). Description: Integument smooth, somewhat thick. Rostrum moderately long, horizontal, 0.45–0.60 carapace length (Fig. 8 A); greatly exceeding cornea and basal article of antennular peduncle and sometimes exceeding second article. Carapace and rostrum with 4–5 dorsal teeth, three postorbital; rostrum with 1–3 ventral teeth. Supraorbital spine moderate; suborbital and antennal spines strong, pterygostomian spine distinct. Abdomen smooth. Pleura of abdominal somites 1–4 rounded; pleura of fourth and fifth abdominal somites with posteroventral spines. Telson 1.5–1.6 times length of sixth somite, with 3–4 pairs of dorsolateral spinules and 14–15 terminal spinules (Fig. 9 E). Eye diameter 0.17–0.2 carapace length; cornea pigmented and slightly dilated; ocellus present. Basal article of antennular peduncle (Fig. 9 A) with one distal, dorsal spine and a strong subdistal, ventromesial spine; stylocerite barely exceeding basal article or reaching to middle of second article of antennular peduncle. Second article with large dorsolateral spine on distal margin; third article with dorsal spine. Dorsolateral flagella with 15–23 thickened segments; distal portion slender, with at least 5 segments; tip of ventromesial flagella broken but probably subequal to dorsolateral flagella. Basicerite of antenna with rounded dorsal lobe and strong ventrolateral spine; carpocerite reaching third article ...
