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 View Figs 50–51 , 99–100 View Figs 99–100 ); abdominal segment VII with 2 ps on each side in both sexes ( Figs 50–51 View Figs 50–51 , 99–100 View Figs 99–100 ); female abdominal segment VI with 1 ps on each side ( Figs 51 View Figs 50–51 , 100 View Figs 99–100 ); male tergopleurite IV without aps ( Figs 50 View Figs 50–51 , 99 View Figs 99–100 ); male tergopleurite VIII with 1 tps on each side ( Figs 50 View Figs 50–51 , 99 View Figs 99–100 ); proximal mesosome rectangular ( Figs 55 View Figs 52–56 , 104 View Figs 101–105 ).

These two species can be separated by the following characters: differences in head shape ( Figs 52 View Figs 52–56 , 101 View Figs 101–105 ), 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 View Figs 101–105 ) than in Br. doisuthepensis sp. nov. ( Fig. 52 View Figs 52–56 ); rugose area of mesosome covering more than half of mesosomal lobes in Br. doisuthepensis sp. nov. ( Fig. 55 View Figs 52–56 ), but covering only distal margin of mesosomal lobes in Br. yunnanensis sp. nov. ( Fig. 104 View Figs 101–105 ); posterior cutout of the gonopore larger in Br. doisuthepensis sp. nov. ( Fig. 55 View Figs 52–56 ) than in Br. yunnanensis sp. nov. ( Fig. 104 View Figs 101–105 ); parameres more elongated in Br. doisuthepensis sp. nov. ( Fig. 54 View Figs 52–56 ) than in Br. yunnanensis sp. nov. ( Fig. 103 View Figs 101–105 ); female subgenital plate with distinct distal ‘neck’ connecting plate to cross-piece in Br. doisuthepensis sp. nov. ( Fig. 56 View Figs 52–56 ), but with shorter connection in Br. yunnanensis sp. nov. ( Fig. 105 View Figs 101–105 ). 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.

Description

Both sexes

Head rounded pentagonal ( Fig. 101 View Figs 101–105 ), 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 View Figs 101–105 ; 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 View 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 View Figs 99–100 . Basal apodeme roughly rectangular, but proximal margin not visible; slightly constricted at about mid-length ( Fig. 102 View Figs 101–105 ); proximal end not clearly visible in examined specimens. Proximal mesosome convexly rectangular, elongated ( Fig. 104 View Figs 101–105 ). 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 View Figs 101–105 . Measurements as in Table 1 View Table 1 .

Female Thoracic and abdominal chaetotaxy as in Fig. 100 View Figs 99–100 . Subgenital plate very broad, roughly quadratic, but with broad connection to wide cross-piece ( Fig. 105 View Figs 101–105 ). Vulval margin bulging somewhat medianly

( Fig. 105 View Figs 101–105 ), 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 View Table 1 .
