Abstract: Galliphilopterus latifrons sp. nov. urn:lsid:zoobank.org:act: B649A017-1C0B-4F62-8760-7C9F1C1FABDB Figs 1–7; Tables 1–2 Differential diagnosis Galliphilopterus latifrons sp. nov. can be separated from G. brunneopectus by the following characters: frons broader and hyaline margin more extensive in G. latifrons (Fig. 3) than in G, brunneopectus; dorsal anterior plate with more rounded, narrower anterior end in G. brunneopectus than in G. latifrons (Fig. 3); mesosome with prominent antero-lateral lobes and broad distal end with lateral extensions in G. latifrons (Figs 4–5), but without anterior lobes and with a narrower distal end without lateral extensions in G. brunneopectus; basal apodeme strongly constricted anteriorly in G. brunneopectus, but of more or less even width throughout in G. latifrons (Figs 4–5); both sexes of G. brunneopectus have a total of 8 sternal setae on the pterothorax, whereas both sexes of G. latifrons have 2–4 setae (Figs 1–2). The female subgenital plate present but poorly sclerotised in G. latifrons (Fig. 7), but not illustrated for G. brunneopectus; a reexamination of the type series of G. brunneopectus is necessary to confirm whether this plate is present in G. brunneopectus, and if so if the shape differs between species. Etymology The specific epithet is derived from ‘ latus ’, Latin for ‘broad’, and ‘ frons ’, Latin for ‘forehead’, referring to the wider and flatter frons of this species compared to G. brunneopectus. Type material Holotype (ex Arborophila gingica) CHINA • ♂; Fujian Province; 8 Apr. 1980; collector unknown; box E0026198, slide 86; NHMC. Paratypes (ex Arborophila gingica) CHINA • 1 ♂, 3 ♀♀; Fujian Province; 8 Apr. 1980; collector unknown; box E0026198, slide 77; NHMC • 3 ♀♀; same data as for preceding; box E0026198, slide 86; NHMC. Type host Arborophila gingica (Gmelin, 1789) – White-necklaced Partridge (Galliformes: Phasianidae). Type locality Fujian Province, China. Description Both sexes Frons broadly flattened, hyaline margin extensive, bulging laterally and extended lateral to marginal carina (Fig. 3). Marginal carina interrupted medianly and laterally, postmarginal carina slender. Dorsal preantennal suture continuous with hyaline margin and reaching lateral margin of head; suture probably also completely separating dorsal anterior plate, but plate with medio-posterior extension overlapping and obscuring median section of suture above mandibles. Preantennal nodi broad, but ill-defined laterally and posteriorly. Head chaetotaxy as in Fig. 3; s1–5 present; pos clearly ventral in examined males, but more lateral in females; illustrated on ventral side for both sexes. Coni longer than scape. Antennae sexually monomorphic. Marginal temporal carina and pre- and postocular nodi slender. Temporal carina extends anteriorly to near antennal socket. Gular plate with convex lateral margins. Thoracic and abdominal segments and chaetotaxy as in Figs 1–2. Pterothorax and tergopleurites II–VIII divided medianly. Leg chaetotaxy as in Figs 1–2; that of male based partially on paratype specimens as holotype has distorted legs. Sternites and ventral sections of tergopleurites absent. Abdominal chaetotaxy variable among specimens and between sides of specimens (Table 2). Genital opening dorsal. Male Subgenital plate and tergopleurites IX–XI absent or too poorly sclerotised to be visible (Fig. 1). Basal apodeme of roughly even width throughout (Figs 4–5), distally with prominently concave margin. Proximal mesosome with antero-lateral extensions. Mesosome widens slightly distally, with distal end shaped as in Figs 4–5. Gonopore not visible; ames and pmes not clearly visible in examined specimens, but lighter spots that appear to be apertures of sensilla present on ventral side as in Fig. 5. Ventral mesosome with narrow, sclerotised ridge in anterior part, seemingly articulating with parameral heads. Parameres slender, with bulging parameral heads (Fig. 6); pst1 dorsal sensilla situated at about half-length of paramere; pst2 microseta situated on lateral margin of paramere near distal tips. Measurements as in Table 1. Female Subgenital plate vaguely visible as slightly darker area as in Fig. 7, but ill-defined in examined specimens; it is unclear whether this character would be more visible in fresh material. Vulval margin almost flat, with distinct cone-shaped fold present medianly; 6–9 short, slender vms and 2–6 stout, short vss on each side; in one female one vms is a macroseta; vss not clearly visible in all specimens; subgenital plate and cone-shaped fold with 11–14 thorn-like vos on each side, most of which are associated with fold, and there directed anteriorly. Measurements as in Table 1.
