Remarks. The striking colour of this species in the Hving condition led the collectors 

 to give it the name of " Harlequin" Pycnogon (see St. 148). Traces of the red markings 

 are still apparent in a few of the specimens. 



In small specimens, although the genital apertures are present, it is not easy to 

 distinguish the sexes. In adult females the genital opening is situated obliquely on a 

 round, blunt eminence that is very conspicuous in some specimens (e.g. from St. 160).

Description. Trunk non-segmented, lateral processes separated by approximately 

 their own diameter. Ocular tubercle conical; eyes, especially anterior pair, well 

 developed. 



Proboscis a trifle shorter than trunk, diameter at distal end approximately 1-5 times

Abdomen short, reaching to middle of first coxa, considerably expanded in centre. 



Palp with second slightly longer than fourth segment ; fifth, sixth and seventh segments 

 subequal and each rather shorter than eighth or ninth. 



Oviger with fourth joint equal to sixth; terminal claw half as long as tenth segment; 

 spines in principal row on each of the four distal segments relatively broader than in
