Busonia serrata Xue & Zhang , sp. nov.

( Figs. 2 E–H, 5A–E)

Description. Length (including wings): male 2.9mm.

Crown and lower part of face ochraceous, face dorsad of antennal bases ochraceous with brown tinge ( Figs. 2 G, H). Pronotum ochraceous, lateral areas more brownish. Mesoscutum and scutellum light chocolate brown, basal triangles darker. Forewing hyaline with light brown tinge, broad band along costa except for a subapical triangle, dark brown ( Fig. 2 F). Mesepimeron dark brown. Legs pale ochraceous, hind leg spinulation reddish brown.

Male genitalia. Pygofer with height more than length, dorsal margin with posterior dorsally projected lobe. Appendage of segment X slender directed ventrally and posteriorly, in posterior view not crossing over each other. Subgenital plate narrow, long, with a few hair-like long setae; about as long as posterior margin of pygofer ( Fig. 5 A). Connective with two arms square, manubrium slender, central lobe broad and lamellate. Style tooth on ventral margin nearer to basal apex than to distal apex, with row of sparsely distributed setae. Aedeagus with atrial region as long as shaft, posterior rim of atrium broad, almost as broad as long, shaft curved anteriorly, with gonopore all along its length projecting beyond curvature of the shaft in lateral view; margins of gonopore finely serrate ( Figs. 5 D, E).

Etymology. The specific epithet refers to the finely serrate margins of the aedeagal gonopore.

Material examined. Holotype: ♂, MALAYSIA: Sarawak (Borneo), Gunung Mulu Nat`L Park, S Miri, N4°02′ 329″ E114°48′ 46.7″, 30–50m, 2006-x-16-22, coll. J.R. Cryan & J.M. Urban, light ( INHS).

Remarks. Busonia serrata sp. nov. can at once be distinguished from all other known species of Busonia by the finely serrate gonopore margin. It also differs from B. curvata sp. nov. (see below) by the aedeagal shaft lateral margin not curved anteriorly in ventral view.
