Outside Japan, Gussakovskij (1935) included Ussurijskij kraj (Primorskij kraj) in the distribution of this species without giving collection data and Stroganova (1968) noted its occurrence in Sikhote-Alin. For the distribution of X. alnivora, Stroganova (1968) wrote “ Gussakovskij (1935) noted its presence in Primorskij kraj (Shkotovo) ”, whereas Gussakovskij (1935) never mentioned this. I was not able to confirm these Russian records of X. ogasawarai by examining the specimens.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).

5F5DF91E88018F0AFF34DF494CD37430.taxon	biology_ecology	Host plants. Juglandaceae: Juglans mandshurica Maxim. var. sachalinensis (Komatsu) Kitam., Pterocarya rhoifolia Siebold et Zucc. Sapindaceae: Acer sieboldianum Miq., Acer palmatum Thunb., Aesculus turbinata Blume. These hosts have been confirmed chiefly by the examined specimens (see Appendix). A long series of specimens from Sapporo are labeled “ Itaya ”, a Japanese name for Acer pictum Thunb. or some species of maples closely related to it. Part of these specimens was referred to by Kono & Sugihara (1939), who recorded Acer palmatum as a host plant of this woodwasp. Xiphydria ogasawarai apparently feeds on several species of Acer.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).

5F5DF91E88018F0AFF34DF494CD37430.taxon	discussion	Remarks. This species can be recognized by the black malar space and legs (Figs 1 A, B, 2 A, B), small number of the antennomeres (13 – 16 [usually 14 or 15]) (Fig. 3 A), and the creamy white lateral spots usually only on the terga 4 – 6 of the abdomen (Fig. 1 A, B) in the female, and by the mostly black malar space and antennae (Fig. 1 C) and the triangular, medially keeled tergum 9 of the abdomen (Fig. 3 B) in the male. Matsumura (1927) described Xiphydria alnivora on the basis of one female and one male from Sapporo, Hokkaido, without designating types. Watanabe (1956) designated the female with “ a determination label in Matsumura’s own handwriting ” (p. 6) as a lectotype and the male as an “ allolectotype ”. Although Watanabe (1956) did not mention it, the lectotype female does not agree with the original description in the number of antennomeres; the lectotype has 16 antennomeres, whereas the original description reads “ Antenna 19 jointed ” (p. 206). This discrepancy caused confusion, as the character was used in the key by Gussakovskij (1935) to separate X. alnivora from X. ogasawarai. According to Matsumura’s original description, X. alnivora has black legs and 19 antennomeres and occurs in Sapporo, Hokkaido. I have not found any specimens agreeing with these features in Matsumura’s collection or elsewhere. Xiphydria ogasawarai has black legs and occurs in Sapporo but has only 13 – 16 (usually 14 or 15) antennomeres, whereas X. nagasei has black legs and 16 – 20 (usually 17) antennomeres but it has been found only in central and western Honshu. Matsumura’s statement, “ Antenna 19 jointed ”, is most probably a lapsus. I would agree with Watanabe (1956) in treating the specimen having 16 antennomeres as the lectotype of X. alnivora and treat X. alnivora as a synonym of X. ogasawarai. The male “ allolectotype ” of X. alnivora actually belongs to X. palaeanarctica. I have studied the female specimen from Mt. Kanmuri, Hiroshima Prefecture, Japan, which was recorded as X. ogasawarai by Takeuchi (1938, 1955), and found it to be X. nagasei.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).

5F5DF91E88008F0DFF34DE8F4A057454.taxon	biology_ecology	Host plant. Unknown. Matsumura’s (1927) material of this species from Sapporo, identified as X. jezoensis or X. alnivora, was collected on Alnus trees, which may be a host plant. Kojima et al. (1962), Okutani (1967) and others recorded several species of plants as hosts of X. palaeanarctica, but their concept of X. palaeanarctica actually referred to X. ogasawarai or a mixture of X. ogasawarai and X. palaeanarctica. There is no reliable host record of X. palaeanarctica based on the reared (emerged) adults or observations of the oviposition.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).

5F5DF91E88008F0DFF34DE8F4A057454.taxon	discussion	Remarks. This species can be recognized by the black malar space (Fig. 2 D), large number of the antennomeres (16 – 20 [usually 17 or 18]) (Fig. 3 C), mainly reddish brown legs (Fig. 1 D, E), and the creamy white lateral spots usually on the terga 3 – 8 of the abdomen (Fig. 1 D, E) in the female, and by the black malar space, partly creamy white antennae (Fig. 1 F) and the apically roundly produced, dorsally rounded tergum 9 of the abdomen (Fig. 3 D) in the male. In Japan, X. palaeanarctica is very rare and has been found only in Hokkaido. Beside a series collected in Sapporo about a century ago (type series of X. jezoensis), I have examined only three specimens, one each collected in 1926, 1958 and 2016 (see Appendix). I was not able to examine the specimen recorded by Togashi (1991). Conde’s (1935) female specimen from Primorskij kraj was identified as X. jezoensis and apparently fits X. palaeanarctica, although it has only 15 antennomeres. The 24 female antennae of X. palaeanarctica I have examined have 16 to 19 antennomeres. More material is needed for full understanding of the range of actual variation. I have examined a female specimen from Hakugan (= Baekam), North Korea, on which Takeuchi (1938) based his first record of X. palaeanarctica from Korean Peninsula. The species treated as X. palaeanarctica by Esaki et al. (1939) is a misidentification of X. eborata Konow, 1899 (Shinohara & Kameda 2019). From the type material of X. alnivora, Watanabe (1956) designated a female specimen as a lectotype and a male specimen as an “ allolectotype ”. Actually the lectotype female belongs to X. ogasawarai while the “ allolectotype ” male belongs to X. palaeanarctica.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).

Legs black, with tibiae and tarsi mostly pale brown; abdomen with creamy white lateral spots on terga 4 – 7. Both antennae with 18 antennomeres; tergum 9 apically roundly produced, dorsally rounded, without median longitudinal keel (Fig. 3 F). Variation. In both sexes: The large creamy white mark extending from inner orbit through malar space and gena up nearly to the lateral vertex is sometimes narrowly interrupted at the posterior part of the malar space. The lateral part of clypeus is often marked with dark amber or creamy white. Female: The length without ovipositor varies from 12.5 to 19.0 mm (partly estimated from damaged specimens without tip of abdomen). The antennal flagellomeres 4 and 5 are sometimes also partly black. There are 16 – 20 (usually 17) antennomeres (n = 11), with the pedicel 1.1 – 1.3 (usually 1.2) × length of the flagellomere 2 (n = 6). The abdomen has the creamy white lateral spots usually on the terga 3 – 8, the spot on the tergum 3 sometimes missing. The sawsheath length is about 0.9 – 1.0 × the basal plate length (n = 4). Male: The length ranges from 10.0 to 14.0 mm. The antenna is black, with most of the flagellum (flagellomeres 3 – 5 to 12 – 14) largely creamy white, with 16 – 18 antennomeres (n = 8). The abdomen sometimes has an additional obscure spot on the tergum 3 or 8.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).

5F5DF91E88078F0EFF34DEB34B2A7574.taxon	discussion	Remarks. This new species can be recognized by the creamy white malar space (Fig. 2 F), large number of the antennomeres (16 – 20 [usually 17]) (Fig. 3 E), mainly black legs (Fig. 1 I), and the creamy white lateral spots usually on the terga 3 – 8 of the abdomen (Fig. 1 I) in the female, and by the creamy white malar space, largely creamy white antennae (Fig. 1 H) and the apically roundly produced, dorsally rounded tergum 9 of the abdomen (Fig. 3 F) in the male. In the keys to Xiphydria species of East Asia or Japan (Gussakovskij 1935; Takeuchi 1938; Togashi 1991), X. nagasei may run to X. alnivora. However, as discussed under X. ogasawarai, the characters given for X. alnivora in those keys are erroneous and X. ogasawarai and X. alnivora are synonymous. Xiphydria ogasawarai and X. nagasei are similar in having black legs but are distinguished by the characters given above. Xiphydria nagasei has been collected only on the mountains in central Honshu (Saitama and Kanagawa Prefectures) and western Honshu (Hiroshima Prefecture). This is now the only species of Xiphydria endemic to Honshu.	en	Shinohara, Akihiko (2019): The Xiphydria palaeanarctica group from Japan (Hymenoptera, Xiphydriidae).
