( Figs 1C–D View FIGURE 1 , 2A–H View FIGURE 2 , 7A–C View FIGURE 7 , 8A–B View FIGURE 8 , 9A–F View FIGURE 9 , 10A–B View FIGURE 10 )

Material examined. Holotype (♂). THAILAND: Nakhon Ratchasima, Wang Nam Khiao, Udom Sap, Sakaerat Environmental Research Station , along trekking route, 14.506, 101.920, on polyporaceous fungus (pileus), 27 Oct 2008, T. Yasunaga [final instar nymph when collected, emerged on Oct 28–29] ( DOAT) GoogleMaps . Paratypes: THAILAND: Same data as for holotype, 1♂, 2♀ ( TYCN) GoogleMaps .

Diagnosis. Recognized by its small size; generally shiny fuscous body partly with red-orange antenna, cuneus and femora; shiny dorsum covered with moderately sparse, fine, reclining setae ( Figs 2B–C View FIGURE 2 , 9B–C View FIGURE 9 ); shallow, sparse punctures on head ( Fig. 9A View FIGURE 9 ); C-shaped left paramere without basal process ( Fig. 8A–B View FIGURE 8 ); and basally inflated, rather short right paramere ( Fig. 8A–B View FIGURE 8 ).

The final instar nymph has a generally orange-brown coloration and wholly darkened antennomeres II and III ( Fig. 2D–E View FIGURE 2 ), which enable it to be distinguished from that of P. kerzhneri ( Fig. 2J–K View FIGURE 2 ).

Description. Male: Macropterous. Body oval, subparallel-sided, small; dorsal surface weakly shining, punctate, with uniformly distributed, pale, short, simple, reclining setae ( Figs 9A–C View FIGURE 9 ). Head fuscous, not porrect, partly pale brown and somewhat tapered anteriorly ( Fig. 1C View FIGURE 1 ); vertex and frons sparsely and shallowly punctate ( Fig. 9A View FIGURE 9 . Antenna pale orange-brown, rather short; antennomere I with creamy extreme apex, about as thick as apical part of II; basal half and apex of antennomere II, and whole antennomeres III and IV dark brown; apical 1/3 of antennomere II incrassate; antennomere III shorter than IV ( Figs 2B, C View FIGURE 2 ). Labium reddish brown, exceeding apex of metacoxa and reaching abdominal sterna VII–VIII; apical part of segment IV darkened ( Fig. 1D View FIGURE 1 ). Pronotum weakly shining, uniformly punctate ( Fig. 9A View FIGURE 9 ); scutellum weakly arched, sparsely punctate ( Fig. 9B View FIGURE 9 ); pleura shiny dark brown, almost glabrous; propleuron sparsely punctate except on its anterior margin; metathoracic scent efferent system greyish brown, with somewhat elongate peritreme ( Figs 1D View FIGURE 1 , 9D View FIGURE 9 ). Hemelytron weakly shining, with uniformly distributed, minute punctures and short, reclining setae; cuneus orange-brown; membrane including veins pale smoky brown. All coxae and femora pale orange-brown; tibial spines pale brown; tarsomere I shorter than II or III; claw with apical tooth. Abdomen reddish brown. Male genitalia ( Figs 8A–B View FIGURE 8 , 9E–F View FIGURE 9 ): Left paramere tumid, C-shaped, without basal process; right paramere rather inflated at basal half. Structure of vesica not confirmed as available specimens are teneral.

Female: Similar in overall appearance to male but body larger, with longer appendages ( Table 1 View TABLE 1 ). Body ovoid. Antennomere II slender, linear, not strongly incrassate apically. Female genitalia: Not examined, as available specimens are teneral.

Measurements: See Table 1 View TABLE 1 .

Etymology. Named for the type locality, Sakaerat in Nakhon Ratchasima Prov., Thailand; a noun in apposition.

Distribution. Thailand (Nakhon Ratchasima) ( Fig. 12 View FIGURE 12 ).

Biology. The present new species was found from the pileus of polyporaceous fungus ( Fig. 2A View FIGURE 2 ) under a tropical dry forest zone. The first author captured several final instar nymphs by hand-challenging, and the samples were reared and successfully developed into adults within a few days (cf. Fig. 2F–H View FIGURE 2 ).
