Both male and female individuals were observed emerging from these logs, as confirmed by the collecting researchers and forest station staff. This co-occurrence supports the association between the male and female specimens. Based on the field investigations conducted by the authors, to date the known distributional range of this new species has only been confined to its type locality. Notably, S. nitobei co-occurs with the new species in the same area, demonstrating two sympatric species (Fig. 19). The niche differentiation of these two species is reflected in their different host plants: S. chimera sp. nov. in Larix spp. and S. nitobei in Pinus spp. Phylogenetic analysis suggests that S. nitobei and S. chimera form sister groups, with each of the monophyletic lineage supported by high posterior probabilities (PP = 100). The observed K 2 P genetic distance of 0.07 between these two taxa, coupled with diagnostic morphological differences, provides conclusive evidence for the status of S. chimera sp. nov., given the current status of knowledge for Sirex . Although the current known distribution of S. chimera remains restricted, its preferred coniferous forest habitat is extensively distributed across northern China.</p></div>	https://treatment.plazi.org/id/F57DEB7A802C5543AB74E35E79FDBAF4	Public Domain	No known copyright restrictions apply.

Although initially collected during field surveys conducted several years ago and known to exhibit a broad distribution across western China, no formal records of this taxon were published prior to this study. Notably, this study is also the first formal description of the male of the species, even though only one specimen was obtained through several years’ fieldwork. This taxon historically classified as a subspecies of S. cyaneus, our phylogenetic analysis suggests that S. dux and S. nitidus form a monophyletic group, which is sister to S. cyaneus . Based on the molecular findings and consistent morphological differentiation, we propose reinstating S. dux stat. rev. as a distinct species.</p></div>	https://treatment.plazi.org/id/F8A8C4EAA20F505EAA5FFC3636E08F85	Public Domain	No known copyright restrictions apply.

Earlier studies mistakenly classified different color variants of it as distinct species (i. e. S. rufiabdominis Xiao &amp; Wu) because their appearance varies greatly. After studying series of specimens (including type series of S. rufiabdominis Xiao &amp; Wu), we discovered that these color variants are merely individually and continuously with no structural differences. Molecular phylogenetic analysis also confirms that they belong to the same species. Therefore, based on both morphological characters and molecular data, we propose S. rufiabdominis Xiao &amp; Wu as a junior synonym of S. nitobei Matsumura, i. e. S. rufiabdominis Xiao &amp; Wu, 1983 syn. nov. Another confusing case is S. sinicus Maa, which was named based on single male holotype from Beijing, where S. nitobei also occurs. By comparing the original description (Maa, 1949) with our examined specimens (the type specimen of S. sinicus has not been examined), we found no significant differences between S. sinicus and S. nitobei . We propose S. sinicus Maa as a junior synonym of S. nitobei Matsumura, i. e. S. sinicus Maa, 1949 syn. nov. Additionally, Xiao and Wu (1983) reported S. imperialis W. F. Kirby, 1882 in China based on specimens deposited in the Chinese Academy of Forestry. Our rechecking of these specimens also identifies them as S. nitobei, confirming that S. imperialis does not occur in China.</p></div>	https://treatment.plazi.org/id/D71D0462A4085794914246157AFC8E02	Public Domain	No known copyright restrictions apply.

This absence could suggest local habitat alterations or undetected ecological requirements. Specimens determined as this species by Xiao are deposited in the collection of the Chinese Academy of Forestry, but their collection date was 1984 (postdating to the original records). This raises questions about their connection to the initial discovery. The ovipositor was not exposed in either of the examined female specimens, preventing examination of this structure.</p><p>Females of this taxon show striking morphological similarity to S. dux, with which it has a substantial range overlap. However, the males of the two species exhibit notable morphological differences (e. g. yellowish hind femur in S. tianshanicus while darkish in S. dux). Detailed comparisons revealed that there are no consistent differences for the standard diagnostic features between the females. A potential distinguishing character is the shape of the median basin on tergum IX (flat-elliptical in Chinese S. dux, cushion-shaped in type specimens of S. dux and S. tianshanicus), but it appears variable across populations, diminishing its diagnostic value. Notably, multiple morphological measurements (including ratio-based characteristics) showed overlapping ranges between these two species across studies. Currently, leg coloration (bright yellow in S. dux while reddish brown in S. tianshanicus) serves as the only provisional diagnostic character for the female specimens, as ovipositor comparisons remain unavailable for S. tianshanicus specimens.</p></div>	https://treatment.plazi.org/id/C198BE2ACEA25CAD88A800AF0C6D6B29	Public Domain	No known copyright restrictions apply.

It is also worth noting that there are conflicting descriptions of the abdominal colors in literature. In Xiao and Wu (1983) and Xiao et al. (1992), it is indicated that abdomen is blackish without metallic reflections. However, the terga II – VII are dull yellowish-brown and terga VII – IX blackish in the description of Quinlyn et al. (2019) (In the original description, abdomen dark bluish, dorsal segments II – VII completely silky, VIII – IX glossy). Existing descriptions of the morphological features align perfectly within the variation range of S. nitobei . This suggests that the species might be merely a synonym of S. nitobei, but this suspicion needs to be confirmed by the examination of the type specimen.</p></div>	https://treatment.plazi.org/id/77DDB09A4BC85503B140E1F73DBB0454	Public Domain	No known copyright restrictions apply.
