Trentepohlia fuscoapicalis is a small species of the sub- 

 genus that is apparently closest to T. curfipennis (Speis.), 

 likewise from Cameroun. This latter species is rust-yellow 

 with the abdominal segments narrowly ringed with brown ; 

 the wings with a large brownish-yellow stigma and with the 

 apex suffused with yellowish.
