On some Ctenarytaina species (Hemiptera, Psylloidea) from Gunung Kinabalu (Malaysia, Sabah)

Gunung Kinabalu is famous for its exceptionally diverse fauna and flora, rich in endemism. An example is the psyllid genus Ctenarytaina that is represented by four, apparently endemic species. Here two new Ctenarytaina species, C. lienhardi sp. nov. and C. smetanai sp. nov., are described from Gunung Kinabalu. The new taxa are diagnosed, illustrated and their relationships to other species in the genus are discussed. Ctenarytaina daleae Burckhardt is redescribed. The species develops on Leptospermum species (Myrtaceae) and not Syzygium as previously suggested.
