Diagnosis
Brueelia yunnanensis sp. nov. is most similar to Brueelia doisuthepensis sp. nov., with which it shares the following characters: abdominal segment IV with 1 ps on each side in both sexes (Figs 50–51, 99–100); abdominal segment VII with 2 ps on each side in both sexes (Figs 50–51, 99–100); female abdominal segment VI with 1 ps on each side (Figs 51, 100); male tergopleurite IV without aps (Figs 50, 99); male tergopleurite VIII with 1 tps on each side (Figs 50, 99); proximal mesosome rectangular (Figs 55, 104).
These two species can be separated by the following characters: differences in head shape (Figs 52, 101), with Br. yunnanensis sp. nov. having proportionately wider temples, with a blunter angle at mts3 than in Br. doisuthepensis sp. nov.; the portion of the temple margin between mts3–5 is more flattened in Br. yunnanensis sp. nov., making the head look somewhat angular; lateral margins of preantennal head are more straight in Br. yunnanensis sp. nov. (Fig. 101) than in Br. doisuthepensis sp. nov. (Fig. 52); rugose area of mesosome covering more than half of mesosomal lobes in Br. doisuthepensis sp. nov. (Fig. 55), but covering only distal margin of mesosomal lobes in Br. yunnanensis sp. nov. (Fig. 104); posterior cutout of the gonopore larger in Br. doisuthepensis sp. nov. (Fig. 55) than in Br. yunnanensis sp. nov. (Fig. 104); parameres more elongated in Br. doisuthepensis sp. nov. (Fig. 54) than in Br. yunnanensis sp. nov. (Fig. 103); female subgenital plate with distinct distal ‘neck’ connecting plate to cross-piece in Br. doisuthepensis sp. nov. (Fig. 56), but with shorter connection in Br. yunnanensis sp. nov. (Fig. 105). Apparent differences in female vulval chaetotaxy may be due to the small number of specimens examined, and may overlap.
Etymology
The specific epithet is derived from the type locality.

Type host
Alophoixus flaveolus burmanicus (Oates, 1899) – white-throated bulbul.
Description
Both sexes
Head rounded pentagonal (Fig. 101), frons narrow and flattened, lateral margins of preantennal area slightly convex. Marginal carina broad, of irregular width, narrowing at frons, and moderately displaced but not much widened at osculum. Head chaetotaxy as in Fig. 101; pos situated far behind eye. Temples somewhat angular, with area between mts3-5 flattened; occiput convex. Thoracic and abdominal segments as in Figs 99–100. Pigmentation yellowish brown, only markedly darker at head nodi, proepimera, metepisterna, and lateral margins of tergopleurites.
Male
Thoracic and abdominal chaetotaxy as in Fig. 99. Basal apodeme roughly rectangular, but proximal margin not visible; slightly constricted at about mid-length (Fig. 102); proximal end not clearly visible in examined specimens. Proximal mesosome convexly rectangular, elongated (Fig. 104). Mesosomal lobes narrowing anteriorly, with rugose area limited to near posterior margin; 2 pmes sensilla posterior to gonopore on each side. Gonopore crescent shaped, stout. Penile arms do not reach posterior margin of mesosome. Parameres stout, elongated, with pst1–2 as in Fig. 103. Measurements as in Table 1.
Female Thoracic and abdominal chaetotaxy as in Fig. 100. Subgenital plate very broad, roughly quadratic, but with broad connection to wide cross-piece (Fig. 105). Vulval margin bulging somewhat medianly
(Fig. 105), with 3–5 short, slender vms and 4–5 short, thorn-like vss on each side; 4–5 short, slender vos on each side; distal 1 vos median to vss. Measurements as in Table 1.
