title: Two new species of the Simulium batoense species-group of Simulium (Gomphostilbia) (Diptera: Simuliidae) from Peninsular Malaysia.
abstract: Two new black fly species, Simulium (Gomphostilbia) tekamense and Simulium (Gomphostilbia) jerantutense, are described based on adult females emerged from pupae in Peninsular Malaysia, and assigned to the binuanense subgroup of the batoense species-group in the subgenus Gomphostilbia. Simulium (G.) tekamense sp. nov. is characterized in the female by the subcosta with 0-2 hairs, and presence of a  deep notch on the apex of the mediolongitudinal ridge of the cibarium, and in the pupa by one of two paired gill filaments of the middle triplet much thicker than the counter filament. Simulium (G.) jerantutense sp. nov. is characterized in the female by the short claw tooth 0.46 times the length of the claw, and in the pupa by the gill filaments arranged as [2+1+(1+2)]+2 filaments from dorsal to ventral. Taxonomic notes are given to distinguish these new species from related species.
