Type material. Holotype: MAlE, HUAI LAO POO CAVE (15°57.680'N, 98°52.510'E, ElEVATION 534 M), UMPHANG SUBDISTRICT, UMPHANG DISTRICT, Tak, Thailand, 16 NOVEMBER 2016, H. ZHAO, Y. LI AND Z. CHEN lEG GoogleMaps . Paratypes: 3 FEMAlES, SAME DATA AS HOlOTYPE .

Etymology. THE SPECIFIC NAME REFERS TO THE TYPE lOCAlITY, AND IS A NOUN IN APPOSITION.

Diagnosis. THIS SPECIES CAN BE EASIlY DISTINGUISHED FROM All KNOWN CONGENERS IN THE P. halabala SPECIES-GROUP BY THE PRESENCE OF A SMAll, SClEROTIZED, SERRATED RETROlATERO-VENTRAl APOPHYSIS SUBDISTAllY ON THE PROCURSUS (ARROW 1 IN FIG. 3B View FIGURE 3 ; FIG. 3D View FIGURE 3 ) AND BY THE PRESENCE OF TWO lARGE VENTRAl SClERITES ON THE VUlVA (ARROW 2 IN FIG. 5B View FIGURE 5 ).
