( Fig. 3 ) Material : 1 adult specimen, holotype (MNHN­Py 1027), station DW47, East coast of Taiwan , N/ O 'Fishery Researcher 1', TAIWAN 2000, 22º56.0'N 121º25.6'E , 498 m ; 02/08/ 2000 , coll. Bouchet, Richer­IRD & Chan. Description : a comparatively small Colossendeis , trunk ( Fig. 3 A, B) typical of the genus, glabrous, unarticulated and without tubercles on lateral processes or anterior of cephalon; lateral processes separated by less than their own diameter. Ocular tubercle a tall dome bearing a distal pointed “spire”; anterior eyes evident, unpigmented. Abdomen fusiform, held above the horizontal, extending to tip of first coxa of fourth leg. Proboscis longer than trunk, widest at one­third its length, thence tapering rapidly distally (form C2 of Fry and Hedgpeth, 1969 ); initially rising from the cephalon, distally turning down. Palp ( Fig. 3 A) of 10 articles, third and fifth articles (P3 and P5) of equal length, P6 to P10 subequal. Oviger of 10 articles, articles 4 and 6 elongate, slender; strigilis ( Fig. 3 C)with simply crenulate compound spines on articles 7 to 10, terminal claw nearly half length of tenth article, not forming pseudochela, but with flattened expansion along ventral margin. Third leg ( Fig. 3 D, E) coxae subequal, naked; long articles sparsely setose, femur shorter than first tibia, second tibia longest; tarsus two­thirds length of propodus, main claw one quarter length of propodus, these three together one fifth length of second tibia (‘brevitarsal’). FIGURE 3 . Colossendeis mycterismos sp. nov. , holotype, A, body, lateral; B, body, dorsal; C, distal oviger articles, with detail of terminal claw and compound spine; D, third leg; E, distal articles of third leg. Scale line = 2.5 mm for A and B, 1 mm for C and E, 4 mm for D. Measurements of holotype (mm) : trunk length (anterior of cephalon to tip of 4th lateral process) 4.1; width across 2nd lateral processes 1.7; proboscis length 5.33; palp article 3 (P3) 2.35, P5 2.35, P6 0.66, P7 0.66, P8 0.55, P9 0.55, P10 0.66; third leg, first coxa 0.59, second coxa 0.6, third coxa 0.59, femur 9.5, first tibia 12.24, second tibia 13.53, tarsus 1.0, propodus 1.5, main claw 0.4. Etymology : from the Greek ‘ mykterismos ’, meaning ‘turning up the nose, sneering’, alluding to the holotype holding its proboscis in a raised position (adjective). Remarks : There is no described species of Colossendeis with sixth and seventh palp articles subequal and tarsus two­thirds of the propodus length. With the third and fifth palp articles subequal, and a narrowly tapering proboscis, the present species resembles the Melanesian species C. pipetta and C. sinuosa ; however, both of those species have their proboscides distally tubular, and tarsus longer than propodus. Gonopores were not evident, so the gender of the present specimen is not known.
