Abstract

Four new species of amblyceran chewing lice of the Myrsidea Waterston, 1915 are described from hosts of the babbler families Leiothrichidae, Paradoxornithidae and Timaliidae in China. They are: Myrsidea attenuata n. sp. from maesi maesi (Oustalet, 1890), Myrsidea zhangae n. sp. from berthemyi (Oustalet, 1876), Myrsidea liopari n. sp. from Lioparus chrysotis amoenus (Mayr, 1941) and L. chrysotis swinhoii (Verreaux, 1871), and Myrsidea suthorae n. sp. from Suthora verreauxi verreauxi Sharpe, 1883. A checklist of host-louse associations for identified and unidentified Myrsidea species known from babblers is provided.

Key words: Phthiraptera, Amblycera, Menoponidae, Myrsidea, new species, Leiothrichidae, Paradoxornithidae, Timaliidae, babblers, China

Introduction

The genus Myrsidea Waterston, 1915, is the most speciose genus of chewing lice, with over 350 described species (Price et al. 2003; Valim & Weckstein 2013). Myrsidea is a cosmopolitan genus, occurring primarily on perching (Passeriformes). Most species are known from a single host species, and species associated with multiple host species typically occur on closely related hosts (Price et al. 2003; but see Sychra et al. 2014). The term “babblers” includes a diverse assemblage of species, covering members of several closely related families (Leiothrichidae, Paradoxornithidae, , Timaliidae), most of which are found in tropical and sub- tropical Asia, including China (e.g. Arlott 2017). Collectively, these families comprise about 300 species (Clements et al. 2018). However, only 28 species of Myrsidea are presently known from hosts of these four families (Price et al. 2003, 2006; Khan et al. 2009; Najer et al. 2012). The known species of Myrsidea are distributed across most of the babbler diversity, but none had been described from and allies (Paradoxornithidae). We here describe the first two species of Myrsidea from parrotbills and allies, as well as two new species from other Chinese bab- blers.

Most specimens were collected following the method described by Gustafsson et al. (2019); however, collections of lice have been carried out by several people over nearly a decade and, therefore, the methods used varied. Lice have been slide-mounted following the technique in Gustafsson et al. (2019). All specimens are deposited in the collec- tion of the Guangdong Institute for Applied Biological Resources, Guangzhou, Guangdong, China (GIABR). Morphological characters and measurements follow the methodology outlined by Valim & Weckstein (2013). Abdominal setal counts of species of Myrsidea are not consistent in the literature, with some authors (e.g. Price et al. 2006; Najer et al. 2012) including the setae of the post-spiracular complex among the tergal setae, while other authors (e.g. Tandan 1972) excluding them. We here follow Clay (1966) and Valim & Weckstein (2013) by count- ing all marginal setae except the post-spiracular setae on tergum I, but only counting the variable setae between the setae of the post-spiracular complex on subsequent segments. We also follow Clay (1966) and Valim & Weckstein (2013) when counting sternal setae, excluding the two antero-lateral setae on each side of sternum II. In most spe- cies treated here, the setae of the lateral sternal brushes are indistinguishable from those on the posterior margin. Therefore, we follow Clay (1966) including all sternal setae on the posterior margin in the total for posterior mar- ginal setae, with all anterior setae (median + brush setae) included within parentheses after the number of posterior marginal setae. All measurements are given in millimeters, as ranges (mean value, when n ≥ 10). Abbreviations used are: ANW = female anus width; AW = abdominal width (taken at segment IV); dhs = dorsal head seta (sensu Clay 1969); GL = male genitalia length; GSL = male genital sclerite length; HL = head length (taken at midline); ls5 = labial seta 5 (sensu Clay 1966); MSPL = metasternal plate length (taken at midline); MSW = mesothorax width; MTW = meta- thorax width; POW = preocular width; PRW = prothorax width; PSPL = prosternal plate length (taken at midline); TL = total length (at midline); TW = head width (taken at temples). Host follows Clements et al. (2018).

Myrsidea sp. 6; Chu et al. 2019: 338.

Type host: Garrulax maesi maesi (Oustalet, 1890) – (Leiothrichidae). Type locality: Nanling Reservation, Ruyang County, Guangdong Province, China. Diagnosis. Myrsidea attenuata is identified as M. assamensis Tandan, 1972, in the keys to males in Tandan (1972). The same type of genital sclerite, with a single median attenuation, is also found in Myrsidea agarwali Khan et al. 2009. These species can be separated by the thoracic and abdominal chaetotaxy (Table 1), particularly the number of setae on the metanotum and on terga I–II (and in male also tergum III). In addition, Myrsidea attenuata can be separated from M. assamensis by number of setae in the femoral brush of femur III: 19–23 setae in female and 16–21 setae in male in M. attenuata (Figs 1–2), but 24–27 setae in female and 22–25 setae in male in M. assamensis. Males of Myrsidea attenuata can be separated from those of M. agarwali by having distinct gaps between the two median-most seta on each side of terga III–V that are distinctly larger than the gaps between the more lateral tergal setae on the same segments (Fig. 1); in M. agarwali, the tergal setae on these segments are evenly spaced. Also, the genital sclerite of M. agarwali appears to lack the distal attenuated section of the median part, which is present in M. attenuata (Fig. 5). Description. Female (n=3). Habitus as in Fig. 2.

Etymology. The specific epithet is derived from “attenuare”, Latin for “to make slender”, referring to the middle section of the genital sclerite. Remarks. In all females, the dorsal side of the abdomen has been displaced slightly to one side due to mount- ing, so that the pleurites are visible only on the ventral side. Our illustration of the abdomen is as seen on the slides, without any symmetrical reconstruction.

Myrsidea zhangae Lei, Chu, Dik, Zou, Wang & Gustafsson, new species (Figs 5, 9, 12–14)

Myrsidea sp. 7; Chu et al. 2019: 338.

Type host: Ianthocincla berthemyi (Oustalet, 1876) – (Leiothrichidae). Given as “Garrulax caerulatus” in Chu et al. (2019: 338), see below. Type locality: Badagongshan, Sangzhi County, Hunan Province, China. Diagnosis. Myrsidea zhangae is identified as M. monilegeri in the key of Tandan (1972). Females of M. monilegeri are unknown, but males of these two species can be separated by the following characters: femoral brush with 26–29 setae in M. monilegeri, but with 18–22 setae in M. zhangae; tergum I with 7 setae in M. monilegeri, but with 3–4 setae in M. zhangae (one specimen of M. zhangae has 9 setae on tergum I); tergum III with 13 setae in M. monilegeri, but with 6–9 setae in M. zhangae; anterior pleural setae present on segments III–VI in M. monilegeri, but only rarely present, and then only on one side, on segments III and V–VI in M. zhangae; sternum II with 27 anterior setae and 20 marginal setae in M. monilegeri, but with 6–11 anterior setae and 10–14 marginal setae in M.

New species of Myrsidea from babblers Zootaxa 4878 (1) © 2020 Magnolia Press · 109 zhangae; genital sclerite with median section longer than lateral sections and lateral sections slender distally in M. monilegeri, but genital sclerite with median section shorter than lateral sections, and lateral sections conspicuously widened distally in M. zhangae.

Tandan (1972) described two females from Garrulax monileger schauenseei that could not be placed unambig- uously in M. monilegeri, and he considered that future collections may resolve this issue. Assuming that Tandan’s females are conspecific with M. monilegeri, the female M. zhangae can be separated M. monilegeri by the follow- ing characters: femoral brush with 27–33 setae in specimens from G. m. schauenseei, but with 23–25 setae in M. zhangae; tergum I with 11 setae in specimens from G. m. schauenseei, but with 4 setae in M. zhangae; each aster of sternum II with 5 setae in material from G. m. schauenseei, but with 4 setae in M. zhangae; sternum II with 2–4 anterior setae and 15 marginal setae in material from G. m. schauenseei, but without anterior setae and with 9–12 marginal setae in M. zhangae. However, much of sternum II is obscured by gut contents in all females examined, and the anterior setae of G. m. schauenseei are said to be medio-lateral, which may suggest that those of M. zhangae are located very medianly and thus overlooked.

(2019: 338), the host given in the collection data associated with specimens of Myrsidea sp. 7 (now M. zhangae) is Garrulax caerulatus (Hodgson, 1836). However, this bird species is restricted to western Yunnan and north Myanmar (Arlott 2017). It appears that the collectors of the lice misidentified the host bird, which was likely Ianthocincla berthemyi, a species that does occur in Hunan, and which is morphologically similar to Garrulax caerulatus. More collections of lice are needed from both bird species to establish the correct identity of the type host of M. zhangae.

New species of Myrsidea from babblers Zootaxa 4878 (1) © 2020 Magnolia Press · 115 Myrsidea liopari Lei, Chu, Dik, Zou, Wang & Gustafsson, new species (Figs 6, 10, 15–17)

Myrsidea sp. 10; Chu et al. 2019: 338.

Type host: Lioparus chrysotis amoenus (Mayr, 1941) – golden-breasted fulvetta (Paradoxornithidae). Type locality: Ailaoshan, Jingdong County, Yunnan Province, China. Other hosts: Lioparus chrysotis swinhoii (Verreaux, 1871). Diagnosis. The male genital sclerite and lack of hypopharyngeal sclerite of M. liopari places this species close to M. bharat Tandan & Clay, 1971, and M. sabthai Tandan & Clay 1971. As female terga I–II are enlarged in M. liopari, this places this species closest to M. bharat in the key of Tandan & Clay (1971). These two species can be separated by the following characters: female tergum I with 10–11 setae in M. liopari (Fig. 16), but with only 2 setae in M. bharat; female terga IV–V with prominent gaps in the setal rows separating the 2 median setae from the other setae in M. liopari (Fig. 16), but with complete or near complete setal rows in M. bharat; tergum IX with 8–12 inner posterior setae in M. liopari (Fig. 16; see below), but with only 2 inner posterior setae in M. bharat. Males of M. liopari differ from those of M. sabthai by having fewer setae on most terga; there is some overlap on terga I–III, but terga IV–VI have a maximum of 12 setae each in M. liopari, whereas these terga have a minimum of 14 setae each in M. sabthai. Males of M. liopari may have 4 inner posterior setae on tergum IX (Fig. 15), whereas in M. bharat there appears to be only 2; however, some examined specimens of M. liopari have only 2 inner posterior setae in total, or have 1 on one side and 2 on the other.

Etymology. The specific epithet is derived from the genus of the type host. Remarks. The female head shape of Myrsidea liopari appears to differ among specimens, including those col- lected from the same host individual, with some of the females having a head shaped as that illustrated for the male (Fig. 15). We have illustrated a female with a rounder anterior head (Fig. 16) to highlight the morphological varia- tion within this species. Specimens from Sichuan (host subspecies L. chrysotis swinhoii) differ from specimens from the type host subspecies by females having 10–12 inner posterior setae on tergum IX (8–9 in specimens from type host). There appears to be no correlation between head shape and locality. Moreover, other characters, including setal counts, are similar among specimens with different head shapes. More specimens and genetic data are needed to confirm whether these specimens represent cryptic species or natural variation in head shape. Since there are no significant morphological differences among specimens collected from the two host subspecies, all specimens are considered conspecific.

Myrsidea suthorae Lei, Chu, Dik, Zou, Wang & Gustafsson, new species (Figs 7, 11, 18–19)

Myrsidea sp. 11; Chu et al. 2019: 338.

Type host: Suthora verreauxi verreuaxi Sharpe, 1883 – golden (Paradoxornithidae). Type locality: Laojunshan, Pingshan County, Sichuan Province, China. Diagnosis. Males of Myrsidea suthorae key to couplet 6 in the key of Tandan (1972), but it does not fit any of the two given options. One is M. singularis, but M. suthorae differs by the shape of its unique genital sclerite, and by a proportionately broader genitalia than M. singularis (see Fig. 11 and fig. 53 in Tandan 1972); however, the abdominal chaetotaxy of these two species is very similar and may entirely overlap. The second option in couplet 6 leads to M. sikkimensis Tandan, 1972, M. sehri Ansari, 1951 and M. erythrocephali; however, these three species have no more than 4 setae on tergum I, whereas M. suthorae has at least 8. Moreover, M. suthorae can be separated from all these species by the presence of 2 setae on sternite II in M. suthorae (absent in the other species), and the presence in M. suthorae of 8–9 inner posterior setae on tergum IX (only 2 inner posterior setae in the other spe- cies).

122 · Zootaxa 4878 (1) © 2020 Magnolia Press lei et al. Discussion

A large number of babbler species are found in China (MacKinnon & Phillipps 2016). The chewing lice parasitis- ing these hosts are generally poorly known, with only 28 species of Myrsidea described from babblers worldwide (Tandan & Clay 1971; Tandan 1972; Rai 1978; Price et al. 2006; Khan et al. 2009; Najer et al. 2012). Only five species have been reported from China (Price et al. 2006; Chu et al. 2019) and four more are described in this pa- per, including the first species from hosts of the family Paradoxornithidae. However, this quantity represents only a small part of the true diversity of Myrsidea lice living on Chinese babblers, and additional species are likely to be recorded and described. In Appendix 1, we have summarised the known distribution of Myrsidea species parasitis- ing babblers worldwide. Some species of Myrsidea can be grouped together based on the structure and shape of their genital sclerites. Among the Myrsidea parasitising babblers, species with similar genital sclerites often parasitise closely related hosts. For example, species of Myrsidea with M-shaped genital sclerite (Figs 8–9) mainly parasitise hosts in the Leiothrichidae, particularly the genera Garrulax and Ianthocincla, which form a monophyletic clade in the phylogeny of Cai et al. (2019). However, some Myrsidea species with M-shaped genital sclerite are also found on hosts of the genus Trochalopteron, which is more distantly related to Garrulax and Ianthocincla (Cai et al. 2019). The species included in Garrulax, Ianthocincla and Trochalopteron all have large bodies, which would suggest that host size may also influence host distribution patterns in Myrsidea. By contrast, other types of genital sclerites (e.g. Fig. 10) are more widely distributed among species of Myrsidea from babblers in the families Leiothrichidae, Paradoxornithidae and Timaliidae (e.g. Myrsidea chilchil Ansari, 1951 and Myrsidea satbhai Ansari, 1951, see Tandan & Clay 1971). Furthermore, some types of genital sclerites (e.g. that of Myrsidea falcatae Price et al., 2006) are remarkably similar to those found in Myrsidea parasitising non-babbler hosts (e.g. thrushes, Turdidae; see Clay 1969). This would suggest that host switching of lice among hosts of differ- ent families may have played a role in the evolutionary history of Myrsidea parasitising babblers. More research is needed before the significance of the association between different types of genital sclerites in species of Myrsidea parasitising babblers and their host distribution can be assessed adequately, including analysis of molecular data. The finding of a previously unknown type of genital sclerite in Myrsidea suthorae (Fig. 11) sug- gests that much remains to be discovered in this genus of lice.

Zosteropidae Yuhina gularis omeiensis Riley, 1930 Myrsidea sp. [3] [1] Unidentified species of Myrsidea reported by McClure et al. (1973). In many cases, the specimens reported by McClure et al. (1973) are likely conspecific with species of Myrsidea described subsequently from the same host. For instance, M. fal- catae was described by Price et al. (2006) from specimens collected by McClure et al. (1973). As we have not seen any of the specimens reported by McClure et al. (1973), we list their unidentified species separately, because we cannot establish whether they represent known or unknown species. [2] Chu et al. (2019). [3] Gustafsson et al. (2019). [4] Alcippe morrisonia was given as the type host of this species by Price et al. (2006), but this host species is now considered to be endemic to Taiwan, with other species in the same complex occurring on the mainland (Zou et al. 2007; Song et al. 2009; Clements et al. 2018).
