Alcippe hueti hueti David, 1874 – Huet’s fulvetta (Leiothrichidae) [see Remarks].</p> <p>Type locality. Dinghushan, Dinghu District, Zhaoqing, Guangdong, China.</p> <p>gnosis. In the key to species in Gustafsson et al. (2019a), Guimaraesiella (Cicchinella) corrugata keys out to Guimaraesiella (Cicchinella) mcgrewi Gustafsson et al., 2019a based on the extent of the dorsal preantennal suture, the structure of the male genitalia, and the fusion of female tergopleurites IX+X and XI. However, these two species can be separated by the following characters: lateral margins of preantennal head more convex in G. (C.) corrugata (Fig. 3) than in G. (C.) mcgrewi; parameral heads with single-pointed median ends of the median extensions in G. (C.) corrugata (Figs 5, 8), but with double-pointed median ends in G. (C.) mcgrewi; gonopore small with triangular lateral extensions in G. (C.) mcgrewi, but large and complicated, without triangular extensions but with large, rough areas bearing what appears to be 1–2 sensilla on each side in G. (C.) corrugata (Figs 7, 11); rugose nodi submarginal in G. (C.) corrugata (Figs 7, 11), but marginal in G. (C.) mcgrewi; patterns of thickenings of distal mesosome in G. (C.) corrugata (Figs 4, 7, 10, 11) different from those of G. (C.) mcgrewi; male tergopleurite VIII with two tps on each side in G. (C.) mcgrewi, but with 1 tps on each side in G. (C.) corrugata (Fig. 1); female subgenital plate with extensive reticulation in G. (C.) corrugata (Fig. 12), but without reticulation in G. (C.) mcgrewi.</p> <p>Description. Both sexes. Head sub-triangular, frons concave (Fig. 3). Marginal carina interrupted laterally and medianly; width of carina irregular, widest near preantennal nodi. Dorsal preantennal suture reaches lateral margins of head and ads, but does not cut off dorsal anterior plate medianly. Head chaetotaxy as in Fig, 3; pos situated ventrally in male, more dorsally in female. Preantennal nodi large, bulging, somewhat pointed medianly, but shape variable among specimens. Antennae not sexually dimorphic or with scape only slightly stouter in male. Preocular nodi much larger than postocular nodi. Temporal marginal carina narrow, with undulating median margin. Gular plate pointed anteriorly. Thoracic and abdominal segments as in Figs 1–2. Measurements as in Table 1.</p> <p>Male. Thoracic and abdominal chaetotaxy as in Fig. 1. One tps on each side of tergopleurite VII. The genitalia differ between two populations: specimens from Dinghushan (including holotype) as in Figs 4–7, and those from Dadongshan with parameres as in Figs 8–9 and mesosome as in Figs 10–11. Mesosome longer than wide, with rounded proximal end protruding laterally (Dinghushan specimens, Fig. 7); lateral margins deeply concave at about mid-section in specimens from Dinghushan (Fig. 7), but almost straight in specimens from Dadongshan (Figs 10–11); distal margin of mesosome flat or slightly convex, with wide dorsal thickening, curved at lateral ends (Figs 4, 10). Mesosome with a ventral, distal pair of submarginal elongated nodi associated with prominent rugose areas on antero-lateral ends on both sides, and 2 pmes microsetae on each side of elongated nodi (Figs 7, 11). Gonopore large, tube-like, arising in anterior end of mesosome; 1–2 ames sensilla on more or less protruding areas on each side of gonopore. Parameres with pointed heads (Figs 5–6, 8–9), ventrally with densely corrugated area on the distal base of head. Parameral blades bulky, curved in specimens from Dadongshan (Figs 8–9) but more straight in specimens from Dinghushan (Figs 5–6); pst1–2 as in Figs 5–6 and 8; pst1 positioned ventrally in specimens from Dinghushan, but dorsally in specimens from Dadongshan. However, in both cases pst2 seta is situated near the lateral margin, and may in fact be marginal in unmounted specimens.</p> <p>Female. Thoracic and abdominal chaetotaxy as in Fig. 2. Subgenital plate rectangular anteriorly, with distal part gently narrowing to slender connection with complete cross-piece (Fig. 12). Irregular reticulation present in distal half of subgenital plate, less prominent in more anterior parts as in Fig. 12. Vulval margin with 4 short, slender vms and 6 short, thorn-like vss on each side; 4 short, slender vos on each side of subgenital plate; distal 1 vos one each side median to or slightly anterior to row of vss.</p> <p>Etymology.

Ex Alcippe hueti hueti: Holotype ♂, Dinghushan, Dinghu District, Zhaoqing, Guangdong, China, 18 March 2019, D.R. Gustafsson, L. Lei, C. Adam, G. Chisamera, Bird-ID J4116, Louse-ID GD-PHTH- 00265 (IZGAS). Paratypes. 1♂, same data as holotype, Louse-ID GD-PHTH-00266 (IZGAS). 2♂, 2♀, same locality and collectors as holotype, 17 Mar. 2019, Bird-ID J4109, Louse-ID GD-PHTH-00267–70 (IZGAS).</p> <p>Non-types: 2♂, 2♀, Dadongshan, Nanling Mountains, Guangdong, China, 11 Mar. 2019, D.R. Gustafsson, L. Lei, C. Adam, G. Chisamera, Bird-ID J4077, Louse-ID GD-PHTH-00271–4 (IZGAS).</p> <p>Remarks. The six males examined differ between the two localities in overall size, particularly in the head, with specimens from Dadongshan being bigger than specimens from Dinghushan. Also, the shape of the male genitalia is different between specimens from the two localities, in particular the mesosome and parameres, which are illustrated separately from each population (Figs 4–7 and 8–11). The distal parameres of the male genitalia are partially everted, approximately to the same degree, in the two illustrated specimens; therefore, differences in their morphology are unlikely to be due to artifacts of position. However, the asymmetry of the gonopore in the Dinghushan specimens may be due to slide mounting, and this structure is likely more similar between specimens from the two populations.</p> <p>It is unclear whether differences in the shape of the mesosome and parameres are taxonomically significant. Since the two collection localities are placed on different mountain ranges, it is possible that the lice on Alcippe hueti hueti differ between ranges, even if the host species and subspecies are the same. More collections in the mountain ranges of South China are needed to establish whether the louse populations from different ranges are effectively isolated from each other, even if the hosts may not be.</p> <p>Moreover, at the time of collection, we had reason to suspect that some of the birds caught at Dadongshan may have originated from further north, as they were morphologically different (DRG pers. obs.). Species of Alcippe in South China form a complex of closely related and morphologically similar taxa. It is possible that some of the hosts at Dadongshan belonged to Alcippe davidi Styan, 1896, the species living in central China, north of the Nanling Mountains; however, this could not be established in the field. Since the specimens of Guimaraesiella described here were taken from birds identified as A. hueti hueti in the field at Dinghushan, this host and locality are regarded as type host and type locality of G. (C.) corrugata. However, if more than one species of Alcippe is regularly present in Dadongshan, at least during the winter, it is conceivable that G. (C.) corrugata may occur on both host species. More collections from birds on the north side of the Nanling Mountains, including birds positively identified as A. davidi, are needed to confirm this hypothesis.</p> <p>Notably, intraspecific differences in size appear to be common among lice belonging to the Brueelia -complex. Gustafsson &amp; Bush (2017: 66) noted that, in general, head dimensions were smaller in specimens of Acronirmus gracilis (Burmeister, 1838) from southern localities than specimens more northern localities, and that lice from migratory swallows collectively contained both small-headed and large-headed lice. Also, Gustafsson &amp; Bush (2017: 172) noted that heads of Traihoriella binhchauensis (Najer &amp; Sychra [in Najer et al.], 2014) showed the same pattern, lice from more southern localities had smaller heads than those from more northern localities. A similar pattern is also seen in a poorly differentiated complex of species in the genus Sturnidoecus Eichler, 1944 (Gustafsson &amp; Bush 2017: 234). Collectively, these examples suggest that differences in size alone may not be a good indicator of species limits in the Brueelia -complex.</p> <p>Furthermore, Gustafsson &amp; Bush (2017: 267) noted that Southeast Asian populations of Rostrinirmus ruficeps (Nitzsch [in Giebel], 1866) were morphologically identical to populations from other parts of Eurasia, except for significant differences in the male genitalia. In particular, mesosomes of Southeast Asian lice are asymmetrical, whereas those from other parts of Eurasia are symmetrical. As most species in the Brueelia -complex are known from only one or a few localities, even in cases where more than one host specimen has been examined, the extent of such male genitalic differences occurring among louse populations in different parts of the host’s range is unknown.</p> </div>	http://treatment.plazi.org/id/617087CC6B6DE25BC0BEFCD8E1E5FF4A	Public Domain	No known copyright restrictions apply.

The species epithet is formed by “ petilus ”, Latin for “slender”, and “lorica ”, Latin for “cuirass” or “corselet”, here referring to the connection between the female subgenital plate and the cross-piece, which is narrower in G. (Cicchinella) petilorica than in most other species of G. (Cicchinella).</p> <p>Type material. Ex Alcippe nipalensis nipalensis: Holotype ♂, Wudian Village, Huyu Township, Ruili City, Dehong Prefecture, Yunnan Province, China, 7 Jan. 2013, Yuchun Wu &amp; Yanhua Zhang, bird ID J0654 GD-PHTH-00470 (IZGAS). Paratypes: 1♀, Banyan King, Daonong Village, Nabang Township, Yingjiang County, Dehong Prefecture, Yunnan Province, China, 27 Dec. 2012, Yuchun Wu &amp; Yanhua Zhang, bird ID J0525, GD-PHTH-00472 (IZGAS). 2♀, same locality and collectors, 28 Dec. 2012, bird ID J0537, GD-PHTH-00474–475 (IZGAS). 1♀, same locality and collectors, 30 Dec. 2012, bird ID J0574, GD-PHTH-00476 (IZGAS). 2♀, same locality and collectors, 27 May 2013, bird ID J1391, GD-PHTH-00479–480 (IZGAS). 1♀, same data as previous, except bird ID J1392, GD- PHTH-00481 (IZGAS).</p> <p>Remarks. The name of the Alcippe species occurring where lice were collected differs among different sources (e.g. Arlott 2017; Zheng 2017; Clements et al. 2019; Liu &amp; Chen 2021; Gill et al. 2021). No additional data from the hosts examined (e.g. feathers, photos, DNA) are available to confirm their identity, and none of the authors were present when the type material of G. (Cicchinella) petilorica was collected. Therefore, we accept the name of the type host as Alcippe nipalensis nipalensis, noting that further collections are necessary to confirm it.</p> </div>	http://treatment.plazi.org/id/617087CC6B66E253C0BEFF4FE5F4FE62	Public Domain	No known copyright restrictions apply.

Guimaraesiella (Cicchinella) yuhinae keys to couplet 8 in the key of Gustafsson et al. (2019a), but it has a combination of characters that does not fit with either choice in the couplet: the gonopore of G. (C.) yuhinae is not crescent-shaped, and the marginal thickening is displaced medianly at the concavity (Fig. 33). The choices in couplet 8 are G. (C.) ambusta Gustafsson et al., 2019a on one hand, and six other species on the other. Among these six species and from the characters listed in couplet 9, G. (C.) yuhinae is most similar to G. (C.) retusa Gustafsson et al., 2019a.</p> <p>However, Guimaraesiella (Cicchinella) yuhinae can be separated from G. (C.) ambusta and G. (C.) retusa by the following combination of male genitalic characters: proximal mesosome rounded in G. (C.) yuhinae (Fig. 33), but rectangular in the other species; ventral sclerite of G. (C.) yuhinae seemingly detached from more distal part and flanked by sublateral thickenings (Fig. 33), but without such structures in the other species; gonopore of G. (C.) yuhinae shaped as in Fig. 33, with small oblique thickenings at distal end, but shaped differently in the other species.</p> <p>In addition, Guimaraesiella (Cicchinella) yuhinae can be separated from G. (C.) ambusta by the following characters: head, especially preantennal area, proportionately wider in G. (C.) yuhinae (Fig. 30) than in G. (C.) ambusta; male tergopleurite V with 3 ps on each side in G. (C.) yuhinae (Fig. 28), but with 2 ps on each side in G. (C.) ambusta; dorsal thickenings of mesosome much longer than wide, essentially longitudinal, in G. (C.) yuhinae (Fig. 31), but wider than long and essentially latitudinal in G. (C.) ambusta; female subgenital plate relatively broader, reticulation more extensive, and vulval margin more flattened in G. (C.) yuhinae (Fig. 34) than in G. (C.) ambusta. Furthermore, Guimaraesiella (Cicchinella) yuhinae can be separated from G. (C.) retusa by the following characters: male abdominal segment IV with 2 ps on each side in G. (C.) yuhinae (Fig. 28), but with 1 ps on each side in G. (C.) retusa; lateral thickenings of mesosomal lobes displaced at concavity in G. (C.) yuhinae (Fig. 33), but not in G. (C.) retusa; connection between female subgenital plate and cross-piece narrower and vulval margin more flattened in G. (C.) yuhinae (Fig. 34) than in G. (C.) retusa.</p> <p>Description. Both sexes. Head trapezoidal, rather broad (Fig. 30), lateral margins of preantennal area more or less straight, frons broadly concave. Dorsal preantennal suture reaches dsms, ads and lateral margins of head. Marginal carina broad, with irregular inner margin, preantennal nodi large, bulging. Head chaetotaxy as in Fig. 30. Antennae sexually monomorphic. Preocular nodi larger than postocular nodi. Marginal temporal carina narrow, widening along posterior margin of head. Gular plate somewhat elongated. Thoracic and abdominal segments and chaetotaxy as in Figs 28–29. Measurements as in Table 1.</p> <p>Male. Sternal plate II hidden by gut content in all examined specimens, and not illustrated. Genitalia with basal apodeme relatively broad, rectangular, with more or less straight lateral margins (Fig. 31). Proximal mesosome rounded (Fig. 33), ventral sclerite small, with pointed proximal end, and seemingly no connection to more distal thickenings of the mesosome; lateral to ventral sclerite are large thickenings of unclear homology. Gonopore as in Fig. 33, with small oblique sclerites in distal end. Mesosomal lobes with postero-lateral point distal to concavity, and more or less rounded distal margins; marginal thickening displaced medianly at concavity; lpmes situated marginally in concavity. Dorsal thickenings of mesosome long. Parameral heads as in Fig. 32; distal parameres folded dorsally in all males examined, so exact shape difficult to ascertain; apparently elongated and attenuated distal to pst2; pst1–2 as in Fig. 31.</p> <p>Female. Subgenital plate roughly triangular, with extensive reticulation (Fig. 34) and moderately wide connection to cross-piece. Vulval margin more or less gently rounded, with 3 long, slender vms and 6–8 short, thorn-like vss on each side; 3–5 long, slender vos on each side of subgenital plate; distal 1 vos median to vss.</p> <p>Etymology. The species epithet is derived from the genus of the type host. This name ultimately derives from “ yuhin ”, the Nepali name for Yuhina gularis Hodgson, 1836, also known as the stripe-throated yuhina.</p> <p>Type material. Ex Yuhina flavicollis rouxi: Holotype ♂, Pingshan Village, Husa Township, Longchuan County, Dehong Prefecture, Yunnan Province, China, 8 Aug. 2013, Yanhua Zhang &amp; Chuying Cui, bird ID J1418, GD- PHTH-00410 [marked with black dot on slide] (IZGAS). Paratypes: 1♂, 5♀, same data as holotype, GD-PHTH- 00410–412 (IZGAS).</p> <p>Remarks. Guimaraesiella (Cicchinella) yuhinae is the first species of Guimaraesiella described from a species of Yuhina, and the first species of a louse in the Brueelia -complex recorded from a member of the family Zosteropidae. In figures 28 and 29, the setae of the femora, tibiae, and tarsi II–III of legs II and III have not been illustrated because they were not clearly visible due to the legs being shrunken and distorted during the slide-mounting of all specimens examined.</p> </div>	http://treatment.plazi.org/id/617087CC6B63E250C0BEFDCFE089FD37	Public Domain	No known copyright restrictions apply.
