The female of the new species can be differentiated from all other species in the T. flavidorsalis species - group by the following combination of characters: a pair of cambered eigynal teeth close together in T. borneoensis sp. nov. (Figs 1A, 2B), whereas rounded halfway and far apart from each other in other species (e.g., T. cangshan in Fig. 3F); copulatory opening located anteriorly in T. borneoensis sp. nov., whereas copulatory duct located in other species; ventro-mesal median lobe with a posterior epigynal hood in T. borneoensis sp. nov., whereas epigynal hood within median lobe in other Taira species; spermathecae tortuous in T. borneoensis sp. nov. (Figs 1B, 2C), whereas simple in other species of this group. Description. Female. Total length 8.09–11.64. Holotype (Fig. 2A) total length 8.00.
