Diagnosis

Males of Phintella siginjai Dhiya’ulhaq sp. nov. are most similar to those of Phintella fodingensis Wang, Mi & Peng, 2023 by the claw-shaped RTA but can be easily distinguished (as well as from those of all other congeners) by the presence of VTA and needle-shaped embolus with median bump ( Fig. 34A–E View Fig ).

Etymology

The specific epithet refers to Keris Siginjai, a legendary keris (traditional dagger) which is the symbol of Jambi City. Noun in apposition.
