( Figs 146–154 , 170–173 ) Type material. HOLOTYPE : ♀ , THAILAND : NAKHON RATCHASIMA: Wang Nam Khieo , Sakaerat Environmental Research Station , 14°30′27″N , 101°55′39″E , 410 m alt., UV light trap , 22 Mar 2014 , T.Yasunaga ( DOAT ) ( AMNH _ PBI 00380645 ). Differential diagnosis. Most similar in general appearance and similarly small size (body length <3.0 mm) to W. kaliyahae Yasunaga, 2012 , from which this new species is readily distinguished by the following characters: pale brown antennal segments I and II ( Fig. 170 ); short antennal segment II that is shorter than head width across eyes; relatively shiny pronotum; golden brown anterior part of hemelytron ( Fig. 171 ); constricted middle margin of embolium ( Figs 149 , 171 ); possession of noticeable stridulatory device (FWS+MFP, Figs 149–150, 152–153 ); pale coxae ( Fig. 172 ); short metafemur almost equal in length to mesofemur ( Fig. 173 ); mesotibia longer than mesofemur; and metatarsomere II as long as III ( Fig. 151 ). Description. Female ( holotype ). Macropterous; body small ( 2.7 mm ); dorsal surface relatively shining, with sparsely distributed, simple upright setae and woolly reclining setae. Head dark brown, weakly shining.Antenna pale brown, partly tinged with red, generally short; segments III and IV dark brown. Labium shiny reddish brown, slightly exceeding apex of mesocoxa. Pronotum and propleuron shining, dark brown; epimeron and episternum shiny reddish brown; scent efferent system pale somber brown; scutellum dark brown, somewhat shagreened, flat. Hemelytron dark brown, with anterior part contrastingly golden brown as in Figs 170–171 , constricted at middle; embolium with rather developed FWS ( Figs 149–150 ); membrane smoky brown, with pale, translucent basal 1/3. Coxae and legs pale brown; protibia, base of mesotibia, apical half of metafemur and whole metatibia reddish brown ( Fig. 173 ); mesofemur as long as metafemur; mesotibia slightly longer than metatibia; metatibia somewhat inflated; MFP distributed on median metafemur ( Fig. 152 ), with each plectrum hemispherical ( Fig. 153 ). Abdomen widely shiny dark brown; abdominal sterna II–IV paler. Female genitalia: Not examined. Measurements (mm). Female ( holotype ): Total length of body 2.70; head width including eyes 0.60; vertex width 0.29; lengths of antennal segments I–IV 0.15, 0.53, 0.35, 0.35; labial length 0.98; basal width of pronotum 0.92; maximum width across hemelytron 1.08; lengths of mesofemur and tibia 0.78 and 1.05; and lengths of metafemur, tibia and tarsus 0.78, 1.10, 0.27. Male . Unknown. Etymology. From Greek, phormictes (or phormiktes = harper), referring to presence of the stridulatory device of this new species; noun in apposition. Biology. A female adult ( Fig. 170 ) was attracted to UV light trap at tropical dry-evergreen forest zone (cf. https:// www.tistr.or.th/sakaerat/sakaeratE/Environment/environment.htm). Distribution. Thailand : Nakhon Ratchasima (this paper).
