 the fifth with a length about three-fourths its diameter; terminal 

 segment slightly produced, broadly oval. Palpi; the first segment

 slightly expanded apically, bidentate, with a rudimentary median 

 tooth; skin finely shagreened; posterior extremity broadly rounded. 



Male. Length 1.75 mm. Antennae dark brown, basally with 

 silvery scales; 17 segments, the fifth with a length a little greater 

 than its diameter; terminal segment much reduced, subglobose. 

 Palpi; the first segment short, irregularly subquadrate, expanded 

 distally, the second short, stout, suboval, the third a little longer, 

 broadly rounded, the fourth one-fourth longer than the third, sub-
