Diagnosis
Brueelia leiae sp. nov. is most similar to Br. doisuthepensis sp. nov. and Br. yunnanensis sp. nov., with which it shares the following characters: abdominal segment IV in both sexes with ps, and abdominal segment VII in both sexes with 2 ps on each side (Figs 50–51, 92–93, 99–100); female abdominal segment VI with 1 ps on each side (Figs 51, 93, 100); male tergopleurite IV without aps and tergopleurite VIII with only 1 tps on each side (Figs 50, 92, 99).
Brueelia leiae sp. nov. can be separated from the other two species by the broader frons (Figs 52, 94, 101), more rounded proximal mesosome (Figs 55, 97, 104), and cup-shaped female subgenital plate with rounded lateral margins (Figs 56, 98, 105). In Br. leiae sp. nov., male tergopleurite VII has 1 tps on each side (Fig. 92), but this is absent in the other two species (Figs 50, 99).
In addition, Br. leiae sp. nov. can be separated from Br. doisuthepensis sp. nov. by the following characters: marginal carina wider in Br. leiae sp. nov. (Fig. 94) than in Br. doisuthepensis sp. nov. (Fig. 52); differences in the shape of the mesosomal lobes (Figs 55, 97); shape of the vulval margin (Figs 56, 98).
Moreover, Br. leiae sp. nov. can be separated from Br. yunnanensis sp. nov. by the following characters: overall head shape (Figs 94, 101); shape of mesosomal lobes (Figs 97, 104); extent of rugose area on distal mesosome (Figs 97, 104).
Etymology
The specific epithet is in honor of Ms Lujia Lei, formerly a student of DRG’s at the Guangdong Institute for Zoology, as a small compensation for her hard work in the field and in the lab, braving torrential rain,
sleepless mountain nights, hundreds of brown shrikes, terrestrial leeches and the possibility of snakes. Reliable, diligent, and all-round great students like her are rare.
Material examined
Holotype (ex Ixos mcclellandii similis) CHINA • ♂; Yunnan Province, Wenshan Zhuang and Miao Autonomous Prefecture, Malipo County, Daping Township, Gaojingliang Village; 15 Jun. 2016; Y. Wu and X. Chu leg.; J3100; GD-PHTH-00276; GIABR.
Paratypes CHINA • 1 ♂, 2 ♀♀; same collection data as for holotype; GD-PHTH-00277–00279; GIABR.
Type host
Ixos mcclellandii similis (Rothschild, 1921) – mountain bulbul.
Description
Both sexes
Head flat dome-shaped (Fig. 94), lateral margins of preantennal area convex, frons flattened to slightly concave. Marginal carina broad, moderately displaced and widened at osculum; width more or less even throughout except for near frons. Ventral anterior plate small, somewhat rectangular. Head chaetotaxy as in Fig. 94; pos located far behind eye. Temples rounded, occiput convex. Thoracic and abdominal plates as in Figs 92–93. Pigmentation pale yellowish brown, except head carinae and nodi, proepimera, and lateral sections of tergopleurites darker brown.
Male
Thoracic and abdominal chaetotaxy as in Fig. 92. Basal apodeme more or less rectangular, not constricted at mid-length (Fig. 95); proximal section not visible in examined specimens. Proximal mesosome elongated, rounded (Fig. 97). Mesosomal lobed rounded, broad, with extensive rugose areas in medio-distal ends; 2 pmes sensilla postero-lateral of gonopore on each side. Gonopore large, crescent shaped. Penile arms reach to distal margin of mesosome. Parameres elongated, with pst1–2 as in Fig. 96. Measurements as in Table 1.
Female
Thoracic and abdominal chaetotaxy as in Fig. 93. Subgenital plate slender, truncated obovate (Fig. 98). Vulval margin straight, slightly convex medianly (Fig. 98), with 0–2 short, slender vms and 3–6 short, thorn-like vss on each side; 3–4 short, slender vos on each side of subgenital plate; distal 1 vos median to vss. Measurements as in Table 1.
Remarks
One examined female has an aps on one side of tergopleurite VII, but this is absent on the other side and on both sides in the other female; we have not illustrated this seta, as aps are usually absent in females of Brueelia spp., and is here presumably an aberration.
