Holotype ( ♂ ). JAPAN : Honshu , Saitama Pref. , Chichibu City , Otaki , near Mameyaki-bashi (bridge), 35.911 , 138.821 , UV lighting, 28 Jun 2014 , T. Tago ( AMNH _ PBI 00378766 ) ( NWHS ). Diagnosis. Currently known by a single male specimen. Recognized by its moderate size; almost immaculate, yellowish green dorsum; relatively narrow head and wide vertex; and structure of the male genitalia. Externally very similar to N. flavoviridis (Yasunaga) ( Fig. 3A ), N. hoberlandti (Kulik) ( Fig. 3B ), N. kawasawai Yasunaga (female unknown), N. makiharai (Yasunaga) ( Fig. 16O ) or N. nozakii Yasunaga ( Fig. 7E–F ) (female unknown); exact identification of these similar species with uniformly pale green and small- to moderate-sized bodies requires dissection and careful examination of the male genitalia. Description. Holotype male : Body elongate ovoid, moderate in size; basic coloration pale yellowish green ( Fig. 4G–H , fading to stramineous in dry-preserved specimen), almost immaculate; dorsal surface shining, with uniformly distributed, pale, simple, semierect setae ( Fig. 14J ). Head uniformly pale, relatively narrow. Antenna pale brown; segment III slightly longer than head width across eyes; segments III and IV brown. Labium shiny pale reddish brown, slightly exceeding apex of mesocoxa; apical 1/3 of segment IV dark brown. Pronotum, scutellum and pleura pale; scent efferent system creamy white. Hemelytron immaculate; membrane pale smoky brown, with pale veins. All coxae and legs pale brown; metafemur with two pale brown, incomplete rings; apex of each tarsomere III darkened; meta-tarsomere II about as long as III ( Fig. 14L ); pretarsal structure as in Fig. 14M . Abdomen uniformly pale. Male genitalia (7A–D, 14N–O): Right paramere short, with bulbous sensory lobe ( Fig. 7A–B ); left paramere with weak apical protuberance on sensory lobe; vesica with sharp, straight spiculum and slender, sword-like ventral sclerite ( Fig. 7C–D , 14O ). Female: Unknown. Measurements : See Table 1 . Etymology. Named for Chichibu City, the type locality of this new species, combined with Latin adjective montis [= of mountain]. Distribution . Japan (Honshu: Saitama Pref. ). Biology. Unknown.
