Yasunaga, Tomohide, 2012, Review of the phyline plant bug tribe Auricillocorini from Asia, with descriptions of a new genus and nine new species from Japan, Nepal and Thailand (Hemiptera: Heteroptera: Miridae: Phylinae), Zootaxa 3530, pp. 1-24 : 20

Wygomiris nanae new species

( Figs. 3 , 9 , 10 C–D)

Diagnosis. Recognized by the large size, long labium, roughened pronotum with a narrow collar, distinctly long, erect setae on the hemelytron, and well developed dorsal and ventral labiate plates of the bursa copulatrix; these diagnostic characters enable this new species to be distinguished from the sympatric, most closely related congener, P. indochinensis Schuh.

Description. Female: Body generally chestnut brown, elongate oval, comparatively large in size; dorsal surface weakly shining, with simple, semierect setae, long, erect setae and sericeous, reclining setae. Head tinged with yellow, weakly shining; clypeus weakly projected. Antenna yellowish brown, terete; apical 1/3 of segment II and entire III mahogany brown. Labium chestnut brown, reaching apex of metacoxa. Pronotum somewhat roughened, with uniformly distributed, simple, semierect setae; collar pruinosed, narrower than base of antennal segment II; ostiolar peritreme 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 dull chestnut brown. Female genitalia ( Fig. 9 ): Bursa copulatrix toughened, with developed dorsal and ventral labiate plates; sclerotized ring enlarged, somewhat twisted posteriorly. Male: Unknown.

Measurements. Ƥ: Total body length 3.6; length from apex of clypeus to cuneal fracture 2.70; head width across eyes 0.71; vertex width 0.30; lengths of antennal segment IIV 0.19, 0.90, 0.57 [IV missing]; labial length 1.20; mesal pronotal length 0.63; basal pronotal width 1.08; width across hemelytron 1.39; and lengths of metafemur, tibia and tarsus 1.13, 1.50, 0.30.

Etymology. Named after Nana-Siri Rungrueang, who helped our field investigations much.

Distribution. Thailand (Nakhon Nayok Prov.).

Biology. Unknown; only a single female adult collected at light is currently available.
