Wygomiris nanae Yasunaga, 2012: 20 (original description).
Type material examined. HOLOTYPE: ♀, THAILAND: NAKHON NAYOK: Sarika (lodge garden), 14°18′39″N 101°18′00″E, at light, 13 Mar 2009, T. Yasunaga (AMNH _PBI 00379518) (DOAT). Additional material examined. VIETNAM: SON LA PROVINCE: Moc Chau, 940 m alt., 20°49′N 104°42′E, light trap, 19 Jun 1997, M. Tomokuni, 2 ♁♁ (NSMT); Dao Cao Pha, 420 m E of Ban Song, 21°09′39″N 103°35′46″E, 23 Jun 1997, M. Tomokuni, 1 ♀ (NSMT).
Differential diagnosis. Most closely related to P. mingorum Schuh, 1984; distinguished by its uniformly dark brown body; smaller eyes; wider vertex; weakly shining, matte pronotum; densely distributed, silvery, reclining setae on hemelytron (Figs 161−163); tapered apical part of left paramere hypophysis (Fig. 188) and longer apical branches on endosoma (Fig. 190), in addition to developed female genital chamber (Fig. 191). Although YASUNAGA (2012) supposed W. nanae as the closest relative of W. indochinensis Schuh, 1984, W. mingorum is now considered to be sister to W. nanae, judging from the similar shape of endosoma bearing three apical branches. In external appearance, W. nanae can be readily distinguished from W. indochinensis and W. mingorum by the uniformly dark brown coloration and dense dorsal vestiture (Figs 161, 163); the latter two species have contrasting two-tone pattern (SCHUH 1984, YASUNAGA 2012) as seen in W. phormictes sp. nov. (Fig. 170).
Redescription. Male. General coloration and shape similar to those of female. Macropterous; body almost uniformly chestnut or dark brown, elongate oval, comparatively large in size; dorsal surface rather matte, with simple, semierect setae, long, erect setae and wooly, reclining setae. Head tinged with red, weakly shining. Antenna reddish brown. Labium reddish brown, reaching apex of mesocoxa. Pronotum somewhat roughened, with uniformly distributed, simple, semierect setae; collar pruinose, narrower than base of antennal segment II; scent efferent system widely ivory white, with a median knob. Hemelytra somewhat lighter than pronotum and scutellum, with uniformly distributed, silvery, reclining setae and sparsely distributed, simple, long, erect setae; membrane smoky brown. All coxae and legs brown, partly tinged with red; meso- and metacoxae lighter.Abdomen shiny chestnut brown, partly reddish except for posterior margin of each sternum (Fig. 161). Male genitalia (Figs 186–190): Pygophore with distinct PS (Fig. 186). Left paramere with apically tapered hypophysis (Fig. 188); endosoma three-branched, with a wide membranous area along secondary gonopore (Fig. 190).
Measurements (♁♁/ ♀♀, mm) [holotype from Thailand]. Total length of body 3.43–3.78 / 3.43 [3.60]; head width including eyes 0.72–0.75 / 0.71 [0.71]; vertex width 0.30 / 0.33 [0.33]; lengths of antennal segments I–IV 0.25–0.26, 0.93, 0.60, 0.48 / 0.24 [0.19], 0.87 [0.90], 0.57 [0.57], 0.51 [?]; labial length 1.20–1.22/ 1.08 [1.20]; basal width of pronotum 1.09–1.16 / 1.19 [1.08]; maximum width across hemelytron 1.32–1.35 / 1.49 [1.39]; and lengths of metafemur, tibia and tarsus 1.09–1.14, 1.65, 0.30 / 1.10 [1.13], 1.59 [1.50], 0.29 [0.30].
Biology. Unknown; all available specimens were collected by UV lightings around arable lands or secondary forests.
Distribution. Thailand (Nakhon Nayok) (YASUNAGA 2012), Vietnam (Son La) (this paper).
