Baguoidea yunnanensis Qin & Zhang , sp. n.

( Figs. 15–27 )

Type material. Holotype, male ( NWAFU), 16 Jul. 1999, 800– 1000 m, Yaoqu, Mangla, Xishuangbanna, Yunnan Province, coll. Irena Dworakowska.

Description. Size. male 3.8 mm.

Ground color red. Vertex with irregular off-white patch medially at each side; eyes greyish with dark patches as in Fig. 15 ; ocelli surrounded by yellowish patches. Scutellum with small yellow patch medially. Fore wing transparent in apical third; hind wing transparent with red tinge basally.

Abdodminal apodemes reaching midlength of segment V ( Fig. 27 ). Male pygofer with about 14 rigid setae on each side of pygofer lobe and posterior setae longer terminally; dorsal lobe-like structure rounded ( Fig. 19 ); ventral pygofer appendage sinuate and bent dorsocaudad, dorsally slightly expanded before apex, apically irregularly serrated at ventral margin ( Figs. 19, 20 ). Subgenital plate with ventral margin curved dorsad in apical half, with row of 8 blunt macrosetae in basal group, 41–43 marginal microsetae, 9 lateral macrosetae in one row on disc followed by about 24 densely and irregular scattered macrosetae apically and numerous fine microsetae arranged in 2–4 irregular rows ( Fig. 26 ). Parameres with 9 apical teeth, about 11 setae and a few sensory pits ( Fig. 25 ). Aedeagal shaft with paired apical processes directed laterad, each with 5 teeth (2 near apex + 3 at tip) ( Figs. 22, 23 ). Anal tube process strongly narrowing in apical part ( Fig. 24 ).

Remarks. Baguoidea yunnanensis Qin & Zhang sp. n. differs from B. rubra Mahmood in having a row of lateral macrosetae on the pygofer disc followed by densely and irregular scattered macrosetae apically (two rows of lateral macrosetae on disc followed by densely and regular apical macrosetae in B. rubra ), and the fine microsetae of the plate numerous in 2–4 irregular rows (fine microsetae few in number in B. rubra ). The new species also differs from B. rufa (Melichar) in having the fore wing mottled with red (red in basal 2/3 and transparent in apical third) (entirely red in B. rufa ), and the aedeagal shaft with paired apical processes each having 2 teeth near apex and 3 teeth at tip (all teeth are restricted to very tip in B. rufa ).

Etymology. The species name alludes to the locality of the type material (Yunnan Province).

Distribution. Currently known only from southwest China (Yunnan Province).
