(Figs. 1–8)
Diagnosis. This species is characterized by the presence of five longitudinal veins in the forewing, the subtriangular female epiproct, and the narrow subtriangular gonapophyses.
Female. Coloration (in alcohol). Body generally creamy white or pale creamy yellow. Head pale yellow with posterior clypeus slightly darker. Antennae yellow. Legs creamy white with tibiae and tarsi pale brown. Forewing hyaline; veins brown. Abdomen yellow, with brown markings on each notum; genital segments pale yellow.
Morphology. Body length 1.34–1.40 mm (n = 8); length from postclypeus to wing tip 1.21–1.34 mm.
Head (Fig. 1) narrowly elongate, with distinct epicranial suture and epicranial arms; head length 0.55 mm, head width 0.41 mm, about 1.35 times as long as wide. Compound eyes ovoid; IO: 0.92 mm, D: 0.56 mm, IO/D: 1.63. Antenna (Fig. 2) length 2.24 mm, with 28 segments, 2.17 times as long as forewing, 0.93–1.85 times as long as body; length of flagellar segments: f1: 0.15 mm, f2: 0.13 mm, f3: 0.14 mm. Lacinia (Fig. 3) distally with two large teeth and two small teeth.
Legs with pulvillus absent; tarsal claw with one preapical teeth (Fig. 4); length of tarsomeres of hind leg: t1: 0.28 mm, t2: 0.13 mm, t3: 0.16 mm, relative lengths of hind tarsomeres: 2.2: 1.0: 1.2. Forewing (Fig. 5) length 1.03 mm, forewing width 0.21 mm, about 4.29 times as long as wide; short, narrow, spear-like, reaching end of abdomen, pterostigma absent, with several short setae on veins and margins. Venation reduced into only five longitudinal veins; R1 short, not reaching costal margin; Rs simple, ending at about distal 1/4 of costal margin; M simple, slightly longer than R, ending near wing tip at posterior margin; R and M fused for a short distance at about proximal 1/3, forming a long proximal cell; Cu1 proximally fused with M, nearly ending at midlength of posterior margin; Cu2 strongly reduced into a indistinct short vein; 1A short, ending at about proximal 1/6 of posterior margin. Hindwing reduced into a small membranous flap with veins absent.
Abdomen ovoid. Epiproct (Fig. 6) subtriangular, sparsely setose, medially much more sclerotized. Paraproct subtriangular with posterior margin medially curved, a spine present near midlength of posterior margin; trichobothrial field with 22 trichobothria. Subgenital plate broad, posterior margin arcuate, medially without any incision. Ovipositor reduced; gonapophyses (Fig. 7) narrow, elongate, and subtriangular, proximally acutely narrowed and strongly curved hook-like. Spermatheca (Fig. 8) ovoid without sclerotization.
Male. Unknown.
Material examined. Holotype female, CHINA: Yunnan Province, Yuxi, domestic habitat, 18.VIII.2006, Kaijian Yang (CAU). Paratypes 7 females, same data as holotype (CAU).
Distribution. China (Yunnan Province).
Etymology. The new species is named after its type locality, Yunnan, China.
Remarks. The new species appears to be closely related to D. domestica in having similar venation of the forewing, but it can be distinguished by the subtriangular female epiproct and the narrow subtriangular gonapophyses. In D. domestica, the female epiproct is subtrapezoidal and the gonapophyses broad and subquadrate.
