(Figs. 1–20)

Type materials. Holotype. Male, China, Yunnan, Tengchong, 8 May, 2012, coll. Yanghui Cao by light trap. Paratypes. 2 males, same data as holotype.

Description. Length, male 5.8–6.0 mm.

Color. General color of body yellow. Vertex orange. Crown with small beige to tan depression on each side of coronal suture, coronal suture yellowish brown (Figs. 1, 3). Eyes dark brown (Figs. 1–4). Ocelli surrounded with milky patch (Figs. 1, 3, 4). Face with longitudinal yellow stripe medially not reaching end of anteclypeus, remaining area of face yellow to whitish (Fig. 4). Pronotum orange centrally, laterally yellow, anterior margin and arcuate area behind eyes marked with small creamy patches (Figs. 1, 3). Mesonotum centrally and basal angles with triangular beige patches (Figs. 1, 3). Fore- and hind wing subhyaline (Figs. 1, 2). Abdomen brown dorsally with irregular sordid yellow patches laterally on each tergite, beige ventrally. Legs yellow except apex of tibiae to tarsus in fore- to hind legs sordid cyan (Fig. 2).

Male basal abdominal apodemes not exceeding middle of segment 6 (Fig. 7). Male pygofer in profile almost triangular, strongly sclerotized dorsally, terminal process bent basoventrad at nearly right angle, hook-shaped, not exceeding end of lobe, along caudoventral margin bearing 46–49 rigid microsetae divided into two groups, lower group arranged in 3 rows; dorsal bridge nearly 1/4 total length of the lobe, apically membranous (Figs. 5, 6, 10–12). Subgenital plate exceeding end of pygofer side, broad at base, A-group setae absent, B-group setae (50–52) arranged in 3–5 rows occupying nearly half length of dorsal margin, C-group setae (19–20) sharply terminated, starting near base and reaching apex of plate, somewhat arranged in two rows in basal half, D-group setae numerous, long, irregularly arranged in 3–6 irregular rows (Figs. 5, 6, 10, 17, 20). Paramere narrowed in caudal 2/3, medially bearing a few fine setae and sensory pits, apex curved at nearly right angle, blunt, and bearing tiny teeth on ventral side (Figs. 5, 6, 10, 17, 19). Aedeagal shaft tubular, broad at base and strongly narrowed distad, apical 2/5 slightly sinuate, apex slightly expanded, poorly sclerotized and rugose, dorso-basal lamella of shaft narrowed dorsad, gonopore apical (Figs. 5, 6, 10, 15, 16). Connective nearly trapezoidal, anterior margin straight medially, caudal margin emarginate in middle (Figs. 6, 18). Anal tube membranous, ventro-basal appendages long, reflexed caudad in profile, in ventral view overlapped near apices (Figs. 5, 6, 10, 13, 14).

Remarks. This new species differs from Flaviata variata Lu & Qin, 2014 in having a longer body (5.8–6.0 mm compared to 5.0–5.2 mm in F. variata) (Figs. 1, 2); dorsal process of pygofer not surpassing the end of the lobe (surpassing end of the lobe in F. variata) (Figs. 5, 10–12); anal tube appendages long and reflexed caudad in profile, in ventral view overlapped near apices (anal tube appendage short, not reflexed caudad in profile and not overlapped in ventral aspect in F. variata) (Figs. 10, 13, 14); and paramere blunt-tipped with tiny teeth apically on ventral side (attenuate and without teeth in F. variata) (Fig. 19).

Etymology. The specific epithet alludes to the long anal tube appendage.

Distribution. China (Yunnan).
