Termitaradus panamensis sp. nov. 
Male, female: Colour of alcohol specimens pale yellowish. 
Very similar save in details, to the Indian T. annandalei Silv., 
from which it differs in the smaller number of lobules on the 
marginal lobes, and in the shape of the flabella, which are elon- 
gate and lanceolate, the broadest part being nearer base than 
apex, the apex itself being very sharply pointed. The dorsal 
surface of the body is minutely papillated, marked into in- 
numerable polygonal areas (chiefly irregular hexagons) by lines 
of slightly larger papillae, and supplied with numerous pores. 
The tibial comb is similar to that described and figured by
