and adjacent region of head and narrow borders of first somite also 

 reddish. Antennse blackish. Legs dusky reddish brown. Anal 

 valves reddish brown along their contiguous mesal margins. 



Body Spirobolus-like in general form and appearance. Of 

 uniform diameter throughout excepting the first few and last few 

 somites. Surface in general appearing smooth and shiny but each 

 somite excepting the first and last marked below on each side with 

 a series of strong longitudinal strise which do not extend up on the 

 sides, the striation extending farther dorsad caudad of the suture 

 than in front of it. 



First repugnatorial pore on the sixth somite. Pores large, each 

 in front of and well removed from the transverse suture. 



Head with a pronounced vertigial sulcus connected from its 

 anterior end to each eye by means of a finer transverse sulcus. 

 Below this the surface is roughened by singular sulci which are 

 more prominent laterally, but the smooth antennae short, clavate, 

 with the first two articles normally lying in a deep groove in front 

 of and below the eye; first four articles sparsely hairy, the re- 

 maining ones densely clothed; sensory cones pale, distinct. 



Eyes black, triangular, trans versally-elongate; ocelli in 5 or 6 

 series; 30 to 40 in number. Setigerous foveolae 3 + 3. 



Plate of first somite large, extending over head to the transverse 

 suture betweens eye and normally covering greater part of an- 

 tennae. Anterior margin curving broadly moderately forward on 

 the sides, the lower anterior corner evenly rounded, the caudal 

 corner projecting somewhat caudad and more narrowly rounded. 

 The lower anterior and the ventral border elevated and set off by 

 a suture, which does not extend across mid-dorsal region. No 

 other distinct sulci. 



Last somite a complete annulus much larger above than below 

 with the caudal dorsal margin evenly rounded and surpassed by the 

 anal valves. Anal valves ventrally smooth. 



Seventh somite in male moderately produced below. Genopods 

 well exposed. Coleopods simple, thin plates, each of which is 

 moderately narrowed distad and narrowly rounded at the apex; 

 below apical portion the mesal border of each is bent subcaudad. 

 Phallopods exceeded by the caleopods. Each with distal division 

 narrowly subconical, distally curving mesad, the tip somewhat 

 obliquely truncate.
