DD58067BCE64FFA1FF10FB752F121616.taxon	diagnosis	Diagnosis. Recognized by its rather ovoid, weakly ant-mimetic body that is not strongly constricted at the middle; sparsely distributed, dark, semierect setae on the dorsum; somewhat clavate antennal segment II; brown hemelytra with a continuous median band of scale-like setae; weakly splayed-out left paramere with rather elongate hypophysis (Fig. 2 A); and slender, J-shaped vesica with a small, bifurcate median process (Fig. 2 B). This new species is most similar in general appearance to P. miyamotoi Linnavuori (Fig. 1 E), from which P. boninanus can be distinguished by the following characters: vertex wider [versus less than 0.6 mm in miyamotoi]; anterior half of scutellar margin with silvery setae [versus anterior 1 / 3 with clustered silvery setae]; short anterior band of silvery setae at an angle of 55 ° to claval commissure (Fig. 1 A) [versus 30 – 35 ° (Fig. 1 E)]; left paramere cup-shaped, with elongate hypophysis (Fig. 2 A) [versus splayed-out with short hypophysis (Fig. 2 C)]; and vesical bifurcate median process smaller, situated rather basally (Fig. 2 B) [versus broader and situated at apical 1 / 3 (Fig. 2 D)].	en	Polhemus, Dan A., Yasunaga, Tomohide (2021): A new species of the plant bug genus Pilophorus Hahn from the Ogasawara (Bonin) Islands, Japan (Hemiptera: Heteroptera: Miridae: Phylinae).

Legs uniformly reddish-brown, all segments clothed with very short, recumbent, gold setae; all tibiae bearing erect, dark brown spines, lengths of these spines not exceeding the width of the respective tibia on which they occur. Ventral surface: Pale shining reddish-brown, ostiolar peritreme prominent, dull yellowish-brown, abdomen missing. Genitalia (Fig. 2 A – B): Left paramere cup-shaped, with blunt, broadly rounded basal lobe (sensory lobe) and slender, tapering distal process (hypophysis) tapering to slight hook apically (Fig. 2). Structures of J-shaped vesica as shown in Fig. 2 B (not removed from phallotheca); median process small, bifurcate. Macropterous female: Overall length 3.90, length from tip of tylus to cuneal fracture 3.00, maximum width (across base of cuneus) 1.50; similar to male in general structure and coloration (Figs. 1 C – D), with following exceptions: ventral abdomen shining blackish brown, with ovipositor sheath extending 0.65 its length posteromedially.	en	Polhemus, Dan A., Yasunaga, Tomohide (2021): A new species of the plant bug genus Pilophorus Hahn from the Ogasawara (Bonin) Islands, Japan (Hemiptera: Heteroptera: Miridae: Phylinae).

DD58067BCE64FFA1FF10FB752F121616.taxon	discussion	Discussion. The Ogasawara Islands (also referred to as the Bonin Islands) are a set of subtropical oceanic islands known to harbor a unique fauna and flora, with a number of endemic organisms (cf. Ministry of the Environment Government of Japan, 2007 – 2011; UNESCO World Heritage Centre, 1992 – 2001). More than ten heteropterans are regarded to be endemic to the island-group, whereas some introduced bugs (predaceous species in particular) threaten the indigenous species (Yasunaga, 1995, 2000, 2001; Yasunaga et al., 1993). Currently, the following sixteen species of the Miridae are known to inhabit the Ogasawara Islands [* considered endemic; † NT: Near Threatened rank in the official Red List of Japanese Ministry of Environment]: Fulvius anthocoroides (Reuter, 1875), Campylomma boharti Carvalho, 1956 *, C. boninensis Carvalho, 1956 *, C. livida Reuter, 1885, Moissonia punctata (Fieber, 1861), Tytthus chinensis (Stål, 1860), Pilophorus boninanus n. sp. *, Sthenaridea piceonigra (Motschulsky, 1863), S. rufescens (Poppius, 1915), Anthophilolygus bakeri (Poppius, 1915), Creontiades brevis Yasunaga, 1997 *, C. coloripes Hsiao, 1963, Lygocorias boninensis (Yasunaga, 1992) * †, Paurolygus sp. (Schwartz & Yasunaga, unpublished data), Taylorilygus apicalis (Fieber, 1861) and Trigonotylus tenuis Reuter, 1893. Our pair of specimens of Pilophorus from this archipelago were previously recorded as P. perplexus by Carvalho (1956) and P. setulosus (Fig. 1 F, 2 F – G) by Schuh (1984), both of which are predominantly associated with deciduous broadleaf trees in temperate or cold temperate climatic zones (cf. Schuh & Schwartz, 1988; Yasunaga, 2001). Some subsequent works (Yasunaga, 2001; Yasunaga & Duwal, 2016; Yasunaga et al., 2021) doubted the occurrence of such species on these isolated subtropical islands. The present new species was also suspected to have been introduced to the islands from another part of Japan or the Nearctic Region (as Ogasawara was administered by the United States after World War II from 1945 to 1978). However, the present examination of the male genitalia verifies that Pilophorus boninanus n. sp. does not match any other congeners known from Japan and adjacent regions. In addition, no Nearctic Pilophorus species is conspecific with it, based on the diagnostic characters including the male genitalia and in the key to the New World Pilophorus congeners provided by Schuh & Schwartz (1988). In the key to Japanese Pilophorus species (Yasunaga et al., 2021), the specimens from the Ogasawara Islands will key out to P. miyamotoi Linnavuori, but P. boninanus n. sp. can be distinguished by the characters mentioned in above diagnosis. The current preponderance of evidence suggests that P. boninanus n. sp. is endemic to Ogasawara Islands, although further field investigation is encouraged to acquire additional specimens and biological data that will allow clarification of its plausible phylogenetic position.	en	Polhemus, Dan A., Yasunaga, Tomohide (2021): A new species of the plant bug genus Pilophorus Hahn from the Ogasawara (Bonin) Islands, Japan (Hemiptera: Heteroptera: Miridae: Phylinae).
