Atrichopogon mendax (as var. of A. flaviceps ) Kieffer, 1922: 156 (description of female, holotype from Taihoku). Syn.

Diagnosis. Female eyes bare; proximal flagellomeres cylindrical; paratergite with 1 seta; scutellum with 6 bristles.

Description. Female. Body brown, legs yellow. Eyes bare, fused along the distance of 5 ommatidia. Proximal flagellomeres cylindrical ( Fig. 1 H), AR 2.46–2.51; flagellum brown, pedicel and first flagellomere yellow. Proboscis long, mandible with 34 distinct teeth, lacinia smooth. Palpus slender ( Fig. 1 B); 3rd palpal segment with sensory pit on distal half. Scutum with numerous long setae, each with distinct dark spot at base. Paratergite with 1 seta. Halter dark brown. Scutellum with 6 bristles. Wing length 1.46–1.58 mm, CR 0.76– 0.77, macrotrichia in all cells, not numerous ( Fig. 2 B). TR (I) 2.5–2.6, TR (II) 2.4, TR (III) 2.2–2.4. Seminal capsule single, slightly ovoid, with short neck, 0.120–0.139 mm long ( Fig. 1 O).

Male unknown.

Material examined. Atrichopogon flaviceps : lectotype female, present designation, labeled as follows: Tainan, Formosa, H. Sauter, Holotypus, X 0 8 [October 1908]. Atrichopogon flaviceps var. mendax , holotype female, Taihoku, Formosa, H. Sauter, 1912, Kieffer det., Typus. SDEI.

Discussion. The description of var. mendax mentions only one female which we treat as the holotype. Atrichopogon flaviceps was described from 6 females. We hereby designate the preserved female as the lectotype. The preserved female types of A. flaviceps and A. mendax represent one species, therefore A. mendax is recognized here as a junior synonym of A. flaviceps .
