The species was originally credited to Penang, localized 

 from a specimen collected by Lobb. There is not the slightest

 Penang. I have here proposed the new generic name Hosean- 

 tli us for this endemic monotypic Bornean genus, as the generic- 

 name proposed by Ridley is invalidated by Hosea, Dennst.
