Mey (2017: 182) included a list of synonymizations of many of his proposed genera with those of Gustafsson &amp; Bush (2017), published a mere month earlier. As these synonymizations were included in the same publication as the original descriptions, the latter are not considered available under Article 11.5 of the Code, which states that to be available, “a name must be used as valid for a taxon when proposed”. Moreover, Article 11.6.3 of the Code states that names “first published after 1960 and treated as a junior synonym on that occasion cannot be made available from that act”. The existence of a question mark before the synonymy of Timalinirmus in Mey’s addendum does not matter, as this still indicates that Mey (2017) was not confident in the validity of this taxon (Yanega, in litt.).</p><p>Thus, the question before us is not whether either of these two new species should be placed in Resartor or “ Timalinirmus ”, but whether there are any data supporting separation of “ Timalinirmus ” from Resartor, in which case a new genus name would be needed for this genus. Based on genetic data presented here, and our re-examination of the original description of the type species of “ Timalinirmus ” and the only other species in this genus, we find no basis for separation between these and the rest of Resartor, beyond differences in head shape. In all previously known species of Resartor, the head is conspicuously longer and more trapezoidal than in the known species of “ Timalinirmus ”.</p><p>However, the species described here, and the genetic data in Fig. 2, suggest that the head shape of Resartor is more variable than previously thought (e.g., Gustafsson et al. 2018). We therefore conclude that the species previously placed in “ Timalinirmus ”, as well as both new species described here, belong to Resartor . Notably, this action does not require any modifications to the morphological circumscription of Resartor; more specimens of Resartor curvus (Gustafsson et al., 2022) comb. nov. are needed to establish whether the detached cross-piece of the female subgenital plate of this species is truly detached, or whether that was an artifact of slide-mounting for specimens examined by Gustafsson et al. (2022). The characters listed in Table 1 are sufficient to separate all known members of Aratricerca, Resartor, and Turdinirmoides . Furthermore, this suggests that the two undescribed species of “ Timalinirmus ” shown in the photographs published by Mey (2017) belong to Turdinirmoides, as suggested by Mey (2017: 182), who synonymized Timalinirmus with this genus.</p><p>Included species</p><p>Resartor acutitemporalis sp. nov.</p><p>Resartor albofulvus Gustafsson et al., 2018</p><p>Resartor apimimus Gustafsson et al., 2018</p><p>Resartor aterrimus Gustafsson et al., 2018</p><p>Resartor breviceps sp. nov.</p><p>Resartor curvus (Gustafsson et al., 2022) comb. nov.</p><p>Resartor effronte (Ansari, 1956)</p><p>Resartor elugeus Gustafsson et al., 2021</p><p>Resartor extraneus Gustafsson et al., 2018</p><p>Resartor grammatoptiliphagus (Mey, 2017)</p><p>Resartor guangxiensis Gustafsson et al., 2018</p><p>Resartor hrabali (Najer &amp; Sychra in Najer et al. 2012) comb. nov.</p><p>Resartor impressifrons (Ansari, 1956)</p><p>Resartor himalayana (Mey, 2017)</p><p>Resartor longisuturalis Gustafsson et al., 2018</p><p>Resartor novofacies (Ansari, 1956)</p><p>Resartor seminudus Gustafsson et al., 2018</p><p>Resartor weigoldi (Mey, 2017)</p><p>Host distribution</p><p>Most species are known from hosts in the Leiothrichidae ( Passeriformes Linnaeus, 1758), but some species also infest Paradoxornithidae Horsfield &amp; Moore, 1854 and Timaliidae Vigors &amp; Horsfield, 1827 .</p><p>Geographical range</p><p>All known species are limited to South and Southeast Asia, with the species described here from Central China being at the northeastern extreme of the range.</p></div>	https://treatment.plazi.org/id/F6558783FFDDFF8F9D6AFD907B65094A	Public Domain	No known copyright restrictions apply.

Whereas in all previously described species (except R. acutitemporalis), the preantennal area is elongated, with almost parallel, barely convex or in some species, concave lateral margins (Fig. 1A–B), in R. breviceps the preantennal area is not elongated, with more markedly convergent and convex lateral margins. Moreover, whereas in other species of Resartor, the temples are angular, in R. breviceps, the temples are gently rounded. In these characters, and overall habitus, R. breviceps is more reminiscent of species in the genera Turdinirmoides (Fig. 1C) or Aratricerca (Fig. 1D). However, R. breviceps can be separated from species in these genera based on having characters typical for Resartor in Table 1, and lacking the characters typical for Turdinirmoides and Aratricerca in that table (see Figs 5–6).</p><p>Etymology</p><p>Specific name is constructed from ' brevis', Latin for 'short', and ' caput', Latin for 'head', referring to the unusually small head of this species, compared to other members of the genus.</p><p>Type material</p><p>Holotype (ex Erythrogenys gravivox cowensae) CHINA • ♂; Hubei Province, Enshi, Erxianyan Provincial Wetland Nature Reserve; 26 Apr. 2024; Zhengzhen Wang leg.; bird ID J5674; louse ID GD-PHTH-01337; IZGAS.</p><p>Paratypes (ex Erythrogenys gravivox cowensae) CHINA • 2 ♂♂; same data as for holotype; louse ID GD-PHTH-01338–9; IZGAS • 2 ♂♂, 6 ♀♀; Hunan Province, Badagongshan, “ Tea Station ”; 23 Jul. 2012; Dongdong Su leg.; bird ID J0098; louse ID GD-PHTH-00404–7; IZGAS • 3 ♀♀; same data as for preceding; bird ID J0103; louse ID GD-PHTH-00408–9; IZGAS .</p><p>Type host</p><p>Erythrogenys gravivox cowensae (Deignan, 1952) – black-streaked scimitar-babbler.</p><p>Type locality</p><p>Erxianyan Provincial Wetland Nature Reserve, Enshi, Hubei Province, China.</p><p>Description</p><p>Both sexes</p><p>Preantennal head not much longer than postantennal head (Fig. 6A), frons concave, lateral margins of preantennal head clearly convex.
