Diagnosis

Brueelia doisuthepensis sp. nov. is most similar to Brueelia yunnanensis 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 ); 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 ); gonopore more slenderly crescent shaped in Br. doisuthepensis sp. nov. ( Fig. 55 View Figs 52–56 ) than in Br. yunnanensis sp. nov. ( Fig. 104 View Figs 101–105 ); proximal part of 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 species name is derived from the type locality.

Material examined

Holotype (ex Alophoixus ochraceus ochraceus ) THAILAND • ♂; Chiang Mai Province, Doi Su Thep ; 10 Apr. 1962; K. Thonglongya leg.; 745; BPBM.

Paratypes THAILAND • 1 ♀; same collection data as for holotype; BPBM .

Type host

Alophoixus ochraceus ochraceus (Moore, 1858) – ochraceous bulbul ( ochraceus ).

Description

Both sexes

Head flat dome-shaped ( Fig. 52 View Figs 52–56 ), lateral margins of preantennal area convex, frons broadly flattened. Marginal carina slender, shallowly displaced and translucent at osculum, median margin of lateral sections weakly undulated. Ventral anterior plate not pigmented and therefore not visible. Head chaetotaxy as in Fig. 52 View Figs 52–56 ; pos located far behind eye. Lateral margins of postantennal head more or less parallel, temples rounded, occiput slightly rounded. Thoracic and abdominal segments as in Figs 50–51 View Figs 50–51 . Pigmentation nearly uniform, pale yellow, but marginal carina, preantennal nodi, proepimera, metepisterna, and lateral sections of tergopleurites slightly darker.

Male

Thoracic and abdominal chaetotaxy as in Fig. 50 View Figs 50–51 ; ss not visible on segments V–VII in single examined male, but may be present. Basal apodeme short and broad ( Fig. 53 View Figs 52–56 ), only slightly constricted at mid- length. Proximal mesosome roughly rectangular ( Fig. 55 View Figs 52–56 ), not visibly narrowed posteriorly. Mesosomal lobes broad, intensely rugose in medio-distal end, and with most of ventral surface scaly; 2 pmes sensilla latero-distal to gonopore. Gonopore crescent shaped, with no lateral extensions. Penile arms do not reach beyond distal margin of mesosomal lobes. Parameres elongated distally ( Fig. 54 View Figs 52–56 ); pst1–2 as in Fig. 54 View Figs 52–56 . Measurements as in Table 1 View Table 1 .

Female

Abdomen of single examined female slightly distorted, and here illustrated approximately. Thoracic and abdominal chaetotaxy as in Fig. 51 View Figs 50–51 . Subgenital plate as in Fig. 56 View Figs 52–56 , with 2 short, slender vms and 4 short, thorn-like vss on each side; 4 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements as in Table 1 View Table 1 .
