Material examined. Holotype (♂). TAIWAN: Nantou Co., Mt. Yu-Shan (1900 m alt.), 23.48, 120.93 4 Jul 1986, K. Baba ( NMNS) ( AMNH _ PBI 00378770 View Materials ) . Paratypes: TAIWAN: same data as for holotype, 1♀ ( TYCN) . Taiwan: Nantou Hsien, Puli , 12 May 1987, S. Gotoh, 1♀ ( TYCN) ; Puli, Habun River , 24.02, 121.13, UV lighting, 20 May 1988, S. Gotoh, 1♂ ( TYCN) .
Diagnosis. Recognized by its moderate sized, elongate oval body ( Fig. 5F View FIGURE 5 ); reddish brown head with pale striae on frons ( Fig. 5G View FIGURE 5 ); darkened apical 1/3 of clypeus; dark brown thoracic pleura and abdomen; and reddish brown metafemur.A combination of these diagnostic characters enables this new species to be distinguished from any other Asian congeners.
Description. Body moderate in size, subparallel-sided (♂)/ elongate-ovoid (♀); dorsum pale green, partly tinged with red ( Fig. 5A View FIGURE 5 ), with densely distributed, pale, simple, reclining setae. Head shiny reddish brown, with pale striae on frons ( Fig. 5B View FIGURE 5 ); basal transverse carina of vertex narrower than pronotal collar; apical 1/3 of clypeus fuscous. Antenna pale brown; apical 1/3–1/4 of segment II, entire III and IV darker. Labium shiny pale brown, slightly exceeding apex of mesocoxa. Pronotum immaculate; thoracic pleura dark brown; scent efferent system creamy yellow, with dark margin, somewhat triangular ( Fig. 18B View FIGURE 18 ); scutellum pale brown. Clavus widely darkened; membrane smoky brown, with pale veins and a semitransparent, pale spot posterior to apex of cuneus. All coxae and legs pale; base of each coxa more or less brownish; metafemur reddish brown; apical part of each tarsomere III darkened; meta-tarsomere II longer than III ( Fig. 18C View FIGURE 18 ); pretarsal structure as in Fig. 18D View FIGURE 18 ; parempodia developed. Ventral side of abdomen widely dark brown (♂)/ pale brown (♀).
Male genitalia ( Figs. 11A–C View FIGURE 11 , 18E–H View FIGURE 18 ): Parameres as in Figs. 11A–B View FIGURE 11 , 18E–F View FIGURE 18 ; left paramere with developed, spatulate process at apex of hypophysis ( Fig. 18E View FIGURE 18 ); vesica with short, broad, almost straight spiculum weakly curved apically and rather wide ventral sclerite ( Figs. 11C View FIGURE 11 , 18G–H View FIGURE 18 ).
Female genitalia ( Figs. 11D–E View FIGURE 11 , 18I–K View FIGURE 18 ): Sclerotized rings thin-rimmed, rather ovoid, mesially separated to each other ( Fig. 11D View FIGURE 11 ); posterior wall as in Figs. 11E View FIGURE 11 , 18J–K View FIGURE 18 ; spinules on interramal sclerite rather sparsely distributed mesially ( Fig. 18J View FIGURE 18 ); interramal lobe small, semi-circular ( Fig. 11E View FIGURE 11 , 18J View FIGURE 18 ); lateral lobe with uniformly distributed, scaly microstructures ( Fig. 18K View FIGURE 18 ).
Measurements: See Table 1 View TABLE 1 .
Etymology. Named after the late Dr. Kintaro Baba, who provided quite a few Taiwanese mirid specimens; a noun in genitive case.
Distribution. Taiwan (Nantou).
Biology. Unknown.
Remarks. In Taiwan, three species originally described by Poppius (1915) under Lygus (sensu lato), L. bipuncticollis , L. matsumurae and L. v-nigrum , are now placed in Neolygus (cf. Schwartz & Kerzhner 1997; Lu and Zheng 1998b; National Museum of Natural Science 2023); of these, L. bipuncticollis is not a genuine member of Neolygus (Yasunaga in prep.). The present work adds four new species to the Taiwanese fauna.
