03E36B5BAF50FF9337C2FE22FD78FE4D.taxon	materials_examined	Diagnosis. The species of this genus are recognized by small body size; variously colored body and dorsum (pale, or yellow, or orange, or pale and black); simple vestiture, usually with pale setae on dorsal and ventral surfaces; presence of distinct red spots or markings on apices of embolium and cuneus; long labium surpassing metacoxa and reaching abdominal segments, except R. albescens with a short labium reaching the apex of the metacoxa; enlarged metafemora, large pulvillus; and semi-coiled or coiled endosoma with an attenuated apex and sub-apically located secondary gonopore (see detailed description in Schuh 1984, pg. 424). Distribution. Pacific Islands, Oriental and Palearctic regions. Discussion. The host association of most Rubrocueocoris species are unknown as many were collected at light. According to references, the genus occurs on wide range of host plants, such as R. nigriceps taken on the flowering tree, Castanopsis indica (Roxb.) Miq. (Fagaceae) (Duwal et al. 2010), and R. calvertae, collected on Macaranga tanarius (L.) Müll. Arg. (Euphorbiaceae) and Pipturus sp. (Urticaceae) (Henry 2017), R. albescens on Pterostyrax corymbosus Siebold & Zucc (Styracaceae), and R. quercicola on Quercus dentata Thunb. (Fagaceae) (Kerzhner 1988). Rubrocuneocoris is one of the six genera placed in the tribe Decomiini (Schuh & Menard 2013) and is now known to contain ten species, including a new species described herein. The members of the genus are variably colored with the dorsum pale white or yellow, or with dark patterns (black or fuscous) or orange; usually with distinct red spots or markings on apices of the embolium and cuneus. In general, Rubrocuneocoris can be confused with Decomia Poppius (1915) due to similar dark markings but the latter genus is easily recognized by the semi-hyaline or hyaline hemelytra. Species of Rubrocuneocoris are found with two types of endosoma. The one we describe here from Vietnam is close to the Chinese species with having simple, stout endosoma, which is different from others. Therefore, we conclude species of Rubrocuneocoris probably arose from two lineages. However, further investigations of more taxa and genomic data are necessary to help clarify their taxonomic status. We note that a species of Rubrocuneocoris described from China, R. lanceus Li & Liu 2008, was transferred to the genus Atractotomoidea Yasunaga 1999 by Yasunaga & Duwal (2015) because it possesses similar morphological and genitalic structure as the type species A. castanea Yasunaga, 1999. However, four species of Rubrocuneocoris described from Taiwan by Lin (2006): R. falcis, R. maculosus, R. nodus, and R. trifidus, were not treated by Yasunaga & Duwal (2015). Also, Henry (2017) mentioned in his diagnostic note that the species described from Taiwan have black, gray, or red spots on the dorsum which is unlike the dorsum of most species included in Rubrocuneocoris. Consequently, we have concluded, based on the dorsal habitus photographs and illustrations of the male genitalia, that the four Taiwanese species are not congeneric with species of Rubrocuneocoris. The recent revised classification by Schuh & Menard (2013) place Atractotomoidea and Rubrocuneocoris in different tribes, Nasocorini and Decomiini respectively. The hind femora in members of the Nasocorini bear a row of distinct spicules on the dorsal distal margin and the dorsal setae and other body vestiture are variable, with either erect or sub-erect pale or black simple setae and with or without scale like setae. Most species of Atractotomoidea have uniformly distributed minute dark spots on the dorsum, simple pale sub-erect setae covering the dorsum and the labium usually only reaches the apices of the metacoxa. As in other genera of Nesocorini, the species of Atractotomoidea bear a row of spicules on dorsal distal margin of the hind femora (we confirmed this feature on two specimens of Atractotomoidea present in our collection). The endosoma is mesially coiled or semi-coiled, with 2 to 3 apical straps, the secondary gonopore is removed from the apex of the endosoma, and the female genitalia have a asymmetrical anterior wall as in Duwal et al. (2010, pg. 41, cf. Fig. 18) in Atractotomoidea monticola Duwal et al., 2010 and A. orientalis Duwal et al. 2010. In contrast, members of tribe Decomiini have a single type of appressed simple pale setae as mentioned in Schuh & Menard (2013). The species of Rubrocuneocoris do not have spots on the dorsum except for distinct red spots or markings on the apices of embolium and cuneus and labium usually reaches the abdominal segments, except in R. albescens, which has a short labium reaching metacoxa. The endosoma is coiled or semi-coiled and variously structured apically, with the secondary gonopore mesial or sub-apical. In the female genitalia, the anterior wall is symmetrical and has a unique circular sclerite on the dorsal labiate plate as presented in Duwal et al. (2010, pg. 42, cf. Fig. 19) and Fig 4 E – F. Although, Lin (2006) did not mentioned a row of spicules on dorsal distal margin of the metafemur, other characters described above, together with male genital structures, suggest that four species of Rubrocuneocoris documented from Taiwan undoubtedly represent the members of Atractotomoidea. Therefore, we propose the following new combinations: Atractotomoidea falcis (Lin 2006) n. comb.; A. maculosus (Lin 2006) n. comb.; A. nodus (Lin 2006) n. comb.; and A. trifidus (Lin 2006) n. comb.	en	Duwal, Ram Keshari, Schwartz, Michael D., Yasunaga, Tomohide (2019): A new species of the plant bug genus Rubrocuneocoris (Hemiptera: Heteroptera: Miridae: Phylinae) from Vietnam.

Phallotheca (Fig 2 F): Large, bent at strong right angle. Parameres: Left (Fig. 2 C): With typical phyline form. Right (Fig. 2 D – E): Small, lanceolate. Female. Unknown. Measurements. (n = 2 ♂). Total body length 2.38 – 2.40; length from apex of clypeus to cuneal fracture 1.6 – 1.64; width of head across eyes 0.58 – 0.60; vertex width 0.28; lengths of antennal segments I-IV 0.18, 0.68 – 0.70, 0.3 – 0.32, 0.26 – 0.28; labial length 0.92 – 0.94; mesal length of pronotum 0.40 – 0.42; basal width of pronotum 0.88 – 0.90; maximum width across hemelytron 1.00 – 1.04; and lengths of metafemur, tibia and tarsus 0.86 – 0.90, 1.14 – 1.20, 0.30 – 0.32. Etymology. Named for type locality of this new species, Vietnam. Distribution. Vietnam (North) Biology. Unknown. Remarks. The general habitus and semi-coiled endosomal structure of Rubrocuneocoris vietnamensis are very similar to R. wudingensis Li & Liu. In the new species the endosoma has an elongated membranous structure with toothed edge, covering and surpassing the basal half of the secondary gonopore; in R. wudingensis, the membranous structure is not continuous to cover the basal half of the secondary gonopore. The orientation of the ventral strap on the anterior surface of the endosoma is similar in the two species but the apex of the strap in R. vietnamensis does not bears any spicules as in R. wudingensis (Fig. 2 A – B, and cf. Fig. 19 (Li & Liu 2008 )). Further, the new species is distinguished externally by pale spines and small brown spots on the tibia whereas in R. wudingensis dark spines are apparently present (Li & Lui 2008). However, we are uncertain about the true coloration of the metatibial spots in R. wudingensis; they probably bear dark spots (brown if not black), which are obvious in the dorsal habitus image (cf. Li & Liu 2008, p. 69 Fig. 4) and are larger than in the new species. The lateral margin of hemelytron in R. vietnamensis is orange red whereas in R. wudingensis the margin and corium are unicolorous. Morphologically, Rubrocuneocoris anandros Yasunaga & Duwal differs from R. vietnamensis by red or sanguineous spots or marks or stripes on head, antennal segment II, pleura, and protibia; R. calvertae Henry by dark brown antennal segment I and yellowish-brown segments II – IV, dark brown pleura and white spots on distal half of hind femur; R. albescens Yasunaga by pale dorsal coloration and shorter labium extending to the metacoxa; R. quercicola by the reddish- or orange-yellow venter; R. bifidus Schuh by yellowish white dorsal coloration; R spiculatus Schuh by deep red abdomen laterally and reddish metafemur; and R. acuminatus Schuh and R. nigriceps Duwal et al. by dark (or fuscous) head and thorax.	en	Duwal, Ram Keshari, Schwartz, Michael D., Yasunaga, Tomohide (2019): A new species of the plant bug genus Rubrocuneocoris (Hemiptera: Heteroptera: Miridae: Phylinae) from Vietnam.

03E36B5BAF54FF9537C2FC2BFD83F836.taxon	materials_examined	Diagnosis. Recognized by its light creamy yellow coloration; almost uniformly darkened antennal segment I; apical part of each femur speckled with sanguineous maculae; and stout endosoma sigmoid and twisted with serrated apical margins. Total body length 3.3 mm, maximum width across hemelytron 0.97 – 1.05 mm. Habitus images and brief diagnoses of both sexes were provided by Yasunaga (2001 b). Description. MALE GENITALIA (Fig. 4 A – D): Endosoma (Fig. 4 D): Stout, strongly sigmoid and twisted at middle, with serrated apical margin. Phallotheca (Fig 4 A): Comparatively elongate, tapered towards apex, not strongly curved nor bent. Parameres: Left (Fig. 4 B): Typical phyline form. Right (Fig. 4 C): Small, with rather wide sensory lobe. FEMALE GENITALIA (Fig. 4 E – I): Genital chamber roundly margined; sclerotized rings U-shaped; posterior wall simple, with interramal sclerite V-shaped. Measurements. (n = 1 ♂ / 2 ♀).

Remarks. As suggested by Yasunaga (2001 a), Rubrocuneocoris albescens is most closely related to R. quercicola known from the Korean Peninsula and Russian Primorsky Territory, based on the present examination of the male genitalia. However, R. albescens has the different color pattern (generally creamy yellow dorsum, uniformly dark antennal segment I and reddish apical part of each femur) and medially twisted endosoma that is not coiled, in addition to being associated with Pterostyrax corymbosus Siebold & Zucc (Styracaceae), whereas R. quercicola was reported from Quercus dentata Thunb. (Fagaceae) (Kerzhner 1988). Type material. Holotype, ♀.
