Scripps Inst. Oceanogr. Univ. California, San Diego, 2000, 31. [p.202, Fig.50]. Female (79,01°10'N, 11°36'W): a, habitus (left side); b, c, urosome (left, dorsal, respectively); d, forehead (dorsal); e, f, genital somite (left, ventral, respectively); g, masticatory edge of right Md (posterior); h, masticatory edge of left Md (posterior); i, left Mx2 (posterior); j, right Mxp (anterior). Nota: in left Md, ventralmost tooth about 2 times length of corresponding tooth on right Md; masticatory edge between 2nd and 3rd, ventralmost teeth flat with a small round swelling close to 3rd.

Paraheterorhabdus (Paraheterorhabdus) illgi female: 1 - Left caudal ramus distinctly longer than right and completely fused with anal segment (Fig.50-c) 2 - Dorsally, posterolateral corners of prosome angular (Fig.50-c). 3 - Laterally, 2nd urosomal somite (Fig.50-b) without a swelling along ventral margin. 4 - Laterally, posterior slope of genital prominence slightly convex (Fig.50-e). 5 - Genital somite about as long as wide (Fig.50-c). 6 - Ventrally, genital operculum (Fig.50-f) longer than wide.

Type locality: 79,01°10'N, 11°36'W. | | | N: | 2 | | | Lg.: | | | (88) M: 2,52; (824) F: 3,56-2,84; M: 3; {F: 2,84-3,56; M: 2,52-3,00} | | | Rem.: | This species is named in honour of Professor Paul L. Illg, specialist in parasitic copepods, well known at Laboratore Arago (Banyuls-sur-Mer, France). After Park (2000, p.80) the species can be distinguished from the congeners by the relatively short ventralmost of the left Md; the 3rd lobe of Mx2 with a seta and spine of similar length, the 4th lobe with 2 spines of greatly different length, spines of the 5th and 6th lobes with long unserrated distal sections; the coxa of Mxp with a relatively long 1st posterior distal seta, and the basis with a proximal medial margin fringed with setules. The female is very characteristic, having a small and narrow genital operculum and the male having an elongate and slightly curved medial projection on the 2nd segment of the right exopod | | | Last update : 27/01/2015 | |
