Tragoniodes gallowayi Gustafsson, Li, Tian, Ren, Sun & Zou, 2025, new species

Tragoniodes gallowayi new species (Figures 16–22) Type host: Tragopan temminckii (Gray, 1831) —Temminck’s tragopan. Type locality: Sichuan Province, China. Diagnosis. Tragoniodes gallowayi can be separated from T. spinicornis by the following characters: head proportionately wider with shorter preantennal area in T. gallowayi (Fig. 18) than in T. spinicornis; female pedicel slender with distal bulge in T. spinicornis, but more evenly broad in T. gallowayi (Fig. 19); male abdominal segment VI with two tcs on each side in T. gallowayi (Fig. 16), but with one tcs on each side in T. spinicornis; female tergopleurites II–IV each with more tcs on each side (II: 7; III 5–6; IV: 6–7) in T. spinicornis, than in T. gallowayi (Fig. 17; II: 5; III–IV: 3 each); bifid structure of ventral basal apodeme with concave proximal margin and longer distal appendages in T. gallowayi (Fig. 21), but with bilobed anterior margin and shorter distal appendages in T. spinicornis; vulval margin concave in T. spinicornis, but convex in T. gallowayi (Fig. 22). Descriptions Both sexes. Head relatively wide, preantennal area rather short (Fig. 18); frons gently rounded. Marginal carina narrow, with sinuous inner margin. Head chaetotaxy as in Figs 17–18; os sexually dimorphic; both sexes with extensive dorsal head sensilla (more than 30 on each side) roughly forming a U-shape across much of head. Temples sexually dimorphic. Thoracic and abdominal segments and chaetotaxy as in Figs 16–17. Male. Scape swollen and elongated compared to female, with posterior margin bearing squamous horn in proximal half (Fig. 18); marginal seta distal to this horn thorn-like, and much of posterior margin of scape distal to horn also squamous; pedicel narrowing slightly distally, somewhat curved; flagellomere I much extended distally into curved horn with squamous inner surface. Ocular seta long, similar to mts1 and mts 3 in length. Temples roughly rounded, but with irregular margin; occipital process absent.Abdominal chaetotaxy (Fig. 16): tergopleurites II–Vi with two tcs on each side; tergopleurite VII with one tcs on each side; tergopleurites II–VII with numerous tps microsetae, the medial of which may be intercalated with tcs; tergopleurite VIII with dense row of short setae, presumably comprising the tps and tcs; tergopleurites II–VII with 3–4 psc on each side, and tergopleurite VIII with lateralmost two setae in row longer than others; ventral surface of abdomen with 3–4 sts on each side of segments III–VI, one central sts on each side on segments VII–VIII, and rows of microsetae on segments II–VI, some of which may be intercalated with sts. Basal apodeme long, clearly more than half the length of genitalia (Fig. 20). Bifid structure with concave anterior margin, roughly triangular lateral lobes, and long distal appendages roughly parallel and reaching to distal half of parameres (Fig. 21). Mesosome comparatively slender. Measurements as in Table 1. Female. Antennae slender, with pedicel almost as broad as scape and somewhat bulbous distally (Fig. 19). Coni short (Fig. 19). Ocular seta short, similar to pos in length (Fig. 17). Temples expanded into acute angles; occipital process present. Abdominal chaetotaxy (Fig. 17): tcs: II: 4–5 on each side, III–IV: 3 on each side, V: two on each side, VI–VIII: one on each side; tergopleurites II–VIII with tps microsetae in rows, the medial of which may be intercalated with tcs; tergopleurites II–VIII with 3–4 psc on each side, the median-most 1–2 are microsetae; ventral surface of abdomen with 2–3 sts on each side of segments III–IV, four sts on each side of segments V–VI, and one sts on each side on segments VII–VIII; rows of microsetae, some of which are intercalated with sts, on segments II–VII, separated into setae following posterior margin of lateral accessory sternal plates and more central ones. Vulval margin slightly convex centrally (Fig. 22), with 15–23 marginal setae, the medial of which are shorter and sometimes more spike-liken than lateral ones, and 16–24 scattered microsetae in subgenital area. Bifid inner structure as in Fig. 22. Measurements as in Table 1. Etymology: The specific epithet is in honour of our colleague Terry D. Galloway (University of Manitoba, Canada), in recognition of his long-standing research on the lice of Canada and Manitoba in particular, producing novel insights on the biology, ecology and population dynamics of lice from several hosts.
