The species name is an adjective referring to the type locality.
Diagnosis.
Thaiderces ngalauindahensis sp. nov. is similar to T. rimbu , but males can be distinguished by lamina connected to the embolus ( Fig. 10D View Figure 10 ) (vs. the absence of lamina connected to the embolus in T. rimbu ) and the embolic stalk is slanted at a 30° incline ( Fig. 10D View Figure 10 ) (vs. embolic stalk rather round and curved in T. rimbu ).
