Material examined. Holotype (♂). TAIWAN: Nantou Co., Mt. Yu-Shan (1900 m alt.), 23.48, 120.93 4 Jul 1986, K. Baba ( NMNS) ( AMNH _ PBI 00378771 About AMNH ) . Paratypes: TAIWAN: same data as for holotype, 1♀ ( TYCN) .
Diagnosis. Recognized by its moderate-sized, ovoid body ( Fig. 5H–I View FIGURE 5 ); orange-brown basic coloration without greenish tinge; widely darkened clavus and apical part of corium. Due to its unique color pattern, this new species is easily distinguished from Taiwanese congeners. Most closely related to N. roseus (Yasunaga, 1991) ( Fig. 1H View FIGURE 1 ) known from Japan and Korea, N. formosaroseus can be distinguished from N. roseus by its smaller size; paler general coloration ( Fig. 5H–I View FIGURE 5 vs. 1H); smaller, flattened peritreme of the scent efferent system ( Fig. 19C View FIGURE 19 vs. 19L); shorter and sparser setae on metatarsus ( Fig. 19D View FIGURE 19 vs. 19M); more developed apical protuberance of left paramere sensory lobe ( Fig. 19G View FIGURE 19 vs. 19N); and slenderer, more strongly curved spiculum and narrower ventral sclerite ( Fig. 19I View FIGURE 19 vs. 19O).
Description. Body oval, relatively stout, moderate in size; basic coloration orange-brown, lacking greenish tinge; dorsal surface with uniformly distributed, pale, simple, reclining setae. Head pale orange-brown; basal transverse carina of vertex about as thick as pronotal collar. Antenna pale brown; apical 1/3 of segment II, entire III and IV dark brown. Labium pale reddish brown, slightly exceeding apex of mesocoxa. Pronotum, scutellum and thoracic pleura uniformly pale orange-brown; scent efferent system creamy yellow, with small, flattened peritreme ( Fig. 19C View FIGURE 19 ). Hemelytra pale orange-brown; clavus and apical part of corium widely darkened; membrane smoky brown, with pale veins and a semitransparent, pale spot posterior to apex of cuneus. All coxae and legs pale brown; base of each coxa more or less brownish; apical part of each tarsomere III darkened; meta-tarsomere II as long as III ( Fig. 19D View FIGURE 19 ); pretarsal structure as in Fig. 19E View FIGURE 19 ; parempodia narrow. Ventral side of abdomen pale orange-brown.
Male genitalia ( Figs. 11F–H View FIGURE 11 , 19G–I View FIGURE 19 ): Parameres with conical protuberances at apex of sensory lobes ( Figs. 11F–G View FIGURE 11 , 19G–H View FIGURE 19 ); right paramere stout; vesica with long, slender, C-shaped spiculum and narrow ventral sclerite ( Figs. 11H View FIGURE 11 , 19I View FIGURE 19 ).
Female genitalia (11I, 19J–K): Sclerotized rings small, elongate ovoid, mesially separated to each other ( Fig. 11I View FIGURE 11 ); spinules on interramal sclerite densely distributed anteriad ( Fig. 19J–K View FIGURE 19 ); interramal lobe wide, somewhat angular laterally.
Measurements: See Table 1 View TABLE 1 .
