Type material. Holotype ♀ (SWUC-T-AM-12-01), MALAYSIA (Borneo), Sabah, 33 Miles Jalan Tambunan, Penampang , 05°48.739′N 116°20.522′E, 1583 m, 15.X.2015, Z.Z. Gao, G.Q. Huang and L.Y. Wang GoogleMaps . Paratypes: 29 ♀ (SWUC-T-AM-12-02~30), with same data as holotype GoogleMaps .

Etymology. The specific epithet refers to the type locality; adjective in apposition.

Diagnosis. 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 View FIGURE 1 , 2B View FIGURE 2 ), whereas rounded halfway and far apart from each other in other species (e.g., T. cangshan in Fig. 3F View FIGURE 3 ); 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 View FIGURE 1 , 2C View FIGURE 2 ), whereas simple in other species of this group.

Copulatory opening located anteriorly. Copulatory ducts short, merging with spermathecae. Spermathecae tortuous and compact. Fertilization ducts short, located posteriorly.

Male unknown.
