Diagnosis.

Carapace surface rugose, with a coarse reticulate sculpturing throughout. Carapace flat (height well less than half the length), with ocular area and front part of thorax on a plane, and fovea well back of PLE, 1.3-1.5 × further from front of carapace than is the back of the PLE. Legs robust, especially the first pair. Embolus begins at prolateral basal corner of bulb; epigyne with central septum. Tip of abdomen black.

Two of the species ( P. bakau and P. kohi ) are distinctive for their black-and-white banding, three others ( P. decorus , P. mandai , and P. planolancis ) are more simply marked with brown and black, while the last ( P. api ) is a red-orange-black ember.

The four new species described here extend the range of Piranthus eastward as far as Borneo. The two previously described species, P. decorus (Thorell 1895; Caleb and Sanap 2017) and P. planolancis ( Malamel et al. 2019; Nafin et al. 2020), are from Myanmar and India. A video of a living female of P. planolancis (specimen AS19.5940) is available in Maddison (2020).
