Zanchius annulatus Distant, 1904
.</p><p>Zonodorus Distant, 1909: 522 (syn. Carvalho 1952: 79).</p><p>Uzeliella Poppius, 1911: 31 (syn. Carvalho 1952: 79).</p><p>Poppiella Bergroth, 1911: 188 (new name for 
Uzeliella Poppius, 1911).</p><p>Habrocoris Wagner, 1951: 153 (syn. Linnavuori 1964: 329).</p><p>Diagnosis.</p><p>Differs from other orthotyline genera by dorsum being generally greenish, shiny, spindle-shaped, sparsely or normally covered with shiny setae (vs dorsum being gradually widened caudad;  Latizanchius Liu &amp; Zheng, 2001); head short and vertical; frons convex; clypeus not or only barely visible dorsally; compound eyes protuberant, set forward on head, removed from anterior pronotal margin; first antennal segment distinctly short, shorter than head width across eyes; exposed part of mesoscutum wide; hemelytra hyaline or subhyaline, wide and rounded; cuneus somewhat small relative to corium (updated from Schuh (1974) and Yasunaga (1999)).</p><p>Discussion.</p><p>The genus  Zanchius has traditionally been diagnosed based on external morphology, particularly its greenish dorsum and head structure with compound eyes that are conspicuously set forward. Species exhibiting these characters have been assigned to  Zanchius within  Orthotylini . However, the diversity in pygophore structure and the male and female genitalia (e. g. Figs 2, 3) within  Zanchius raises questions regarding its monophyly.</p><p>Additionally, Liu and Zheng (2001) established the genus  Latizanchius, primarily distinguishing it from  Zanchius based on differences in body shape and the ratio between the first antennal segment and head width. Notably, the genital structures of  Latizanchius also exhibit significant variation (Liu and Zheng 2001).</p><p>Zanchius is a species-rich group within  Orthotylini, and the female genitalia are scarcely studied. As the need for monophylogical assessment has already been emphasized for other genera of  Orthotylinae (e. g.  Pseudoloxops Kirkaldy, 1905; see Yasunaga et al. 2022; Kim et al. 2024), a similar evaluation is required for  Zanchius . Future studies should test the monophyly of  Zanchius and its allied genera, as well as reassess the placement of species currently assigned to  Zanchius .</p><p>After the recognition of natural groups within  Orthotylinae (e. g. the  Falconia,  Zanchius groups) by Schuh (1974), it has been proposed that the  Zanchius group should be upgraded to a new tribal level, as it possesses distinct morphological characters that differentiate it from the traditional  Orthotylini (e. g. a dorsally flattened head with small, anteriorly directed eyes set apart from the pronotum, delicate and often semitransparent forewings; Yasunaga and Duwal 2017).</p><p>Recently, Bolshakova and Konstantinov (2022) provided a molecular phylogeny of the  Orthotylinae, revealing that the  Zanchius group is indeed monophyletic and separated from other  Orthotylini members. Additionally, Bolshakova and Konstantinov (2022) presented the morphological characters of its representatives.</p><p>In our study, we conducted a review of the genus  Zanchius in Vietnam, providing not only previously known morphological features but also new insights into the largely unstudied female genitalia. Notably, the interramal lobe extends far beyond the interramal sclerite (Fig. 3 B, D), a character shared with other members of the  Zanchius group (e. g.  Malacocoris Fieber, 1858 and Filicicapsus Bolshakova &amp; Konstantinov, 2022; see Bolshakova and Konstantinov 2022: fig. 6 b, d). Although further examination of female genitalia from a greater number of species within  Zanchius is necessary given the genus’s size, these data will serve as a foundation for the potential elevation and diagnosis of the  Zanchius group at the tribal level.</p></div>	https://treatment.plazi.org/id/CDE4E6DBDC9E5D97A5B2F9B749F4F9A9	Public Domain	No known copyright restrictions apply.

This conclusion is drawn notwithstanding the antennal segment measurement for  Z. quinquemaculatus (antennal segment lengths = 0.25: 1.25: 0.8: 0.8) reported in the original description by Zou (1987), which differ from our observation. Furthermore, our direct examination revealed two spiculi in the endosoma, whereas only one spicule was described by Zou (1987). We infer that one spicule was overlooked in Zou’s (1987) description.</p><p>Notes on habitat sharing</p><p>In our investigation, the four species of the genus  Zanchius were observed to be exclusively associated with the host plant  Mallotus barbatus ( Euphorbiaceae), which had been damaged solely by auchenorrhynchan species (Fig. 4). This suggests that the presence of  Zanchius species on the host plant may be linked to the damage caused by the phytophagous species, which likely serve as prey for these opportunists. While other plant species exhibited signs of damage from auchenorrhynchans,  Zanchius species were found only on specific host plants where both the damage and the phytophagous insects were present. This may indicate a strong host plant association, in which damage by auchenorrhynchans plays a role in attracting  Zanchius species, possibly due to the availability of prey or specific ecological conditions provided by these plants (Messelink et al. 2012). Previous studies have reported that other  Zanchius species (e. g.  Z. tarasovi Kerzhner, 1988) are also found on host plants affected by auchenorrhynchan species, indicating that this association is not unique to the species observed in our study (Yasunaga 1999).</p><p>Among the four species of the genus  Zanchius observed in this study,  Z. marmoratus was collected in significantly greater numbers compared to the other species and is known to have a wider geographical distribution. These findings suggest that  Z. marmoratus may possess a competitive advantage over the other species when sharing the same host plant. Moreover, given the extensive distribution of the host plant,  Mallotus barbatus (rainging from India to China), it is plausible that  Z. marmoratus (or the genus  Zanchius as a whole) has the potential for a broader geographic range.</p><p>While our observations confirm a strong association between the four  Zanchius species and  Mallotus barbatus, the possibility of a broader host plant range should not be overlooked. Some  Zanchius species, including  Z. tarasovi, have been documented on phylogenetically diverse plant lineages, which may suggest a connection to the zoophytophagous nature of the genus. Given this broader host association in other  Zanchius species, the four species examined in this study may also utilize additional host plants, despite our current observations being limited to  Mallotus barbatus . Further investigations are needed to determine the extent of their host plant flexibility and its ecological implications.</p></div>	https://treatment.plazi.org/id/0DD446054B3F5449A11B41DA2C784B9E	Public Domain	No known copyright restrictions apply.
