designation.) 
Ctenonomia CAMERON. 
Journ. Straits Branch Roy, Asiatic Soc., vol. 39, p. 178, 1903. 
Type.—Ctenonomia carinata CAMERON, 1903. (Monobasic.)

Ctenoplectra Kirsy (=Ctenoplectra F. SmiruH, 1858). 
In Kirby and Spence, An introduction to entomology, vol. 3, p. 681, 1826. 
No species. 
Type.—Ctenoplectra chalybea F. SmirH, 1858. (Present designation; first 
species included. ) 
Proposed as a “subgenus near Saropoda” Latreille. 
Isogenotypie with Ctenoplectra F. Smith. 
Since the only character given by Kirby for Ctenoplectra (the crescent-shaped 
inner calear of the hind tibia, with its inner edge finely pectinate) is in 
agreement with Smith’s description and illustration of that structure in 
his species chalybea, that species is transferred to Ctenoplectra Kirby and 
designated its type. Apparently Ctenoplectra Kirby has, until now, been 
a genus without species.
