(Figs. 13–14)  
 Holotype. China. Xishuangbanna female [China / Yunnan /Xishuangbanna/ 15 June 1957 / L. Zang] (IZAS).   
 Description. Female: length: 4.5 mm (n ¼ 1). width: 2.5 mm (n ¼ 1). Head: medium-sized; punctures small; glabrous; frons 0.22 as broad as head across eyes, glabrous. Rostrum: length: 3.4 mm (n ¼ 1); 0.76 as long as body; cylindrical, as broad at base as apex; punctures small; almost straight from base to midpoint then abruptly deflected back to posterior; scrobe lateral; scape inserted in basal half. Antennae: length: scape 1.2 mm; funiculus segment one 0.4 mm, two 0.2 mm, three 0.2 mm, four 0.15 mm, five 0.15 mm, six 0.1 mm, seven 0.15 mm; club 0.4 mm, funicle 1.35 mm (n ¼ 1); scape 0.88 as long as funicle; scape as long as funicular segments 1–4; club medium-sized, oval, acuminate, as long as funicular segments 5–7. Thorax: length: 1.5 mm (n ¼ 1), width: 2.0 mm (n ¼ 1); 0.75 as long as broad; disc trapezoidal, broad at base, angled on straight line to constriction; clothed with narrow, elongate, testaceous scales; pleuron with clavate testaceous scales; anteroventral with short, broad, white scales; mesosternal intercoxal process not visible; scutellum small, as long as broad, clothed with white scales; mesepimeron densely clothed with clavate, testaceous scales; mesepisternum clothed with clavate, testaceous scales; metepisternum clothed with narrow, elongate, testaceous scales; procoxae clothed with clavate white scales; metasternum clothed with narrow, clavate, testaceous and white scales. Elytra: length: 2.0 mm (n ¼ 1); striae deep with small punctures and narrow, elongate, testaceous scales and a few white scales laterally; crosshatched setae prominently erect, piceous; disc flat in lateral view. Legs: length of hind femur 2.0 mm (n ¼ 1), tooth large, wedge shaped; pro- and mesofemoral teeth medium; profemur bent basally with robust club; meso- and metafemur with moderate-sized club, moderately broad basally, clothed with narrow, elongate, white scales; tibiae almost straight except for base; pro- and mesouncus large, twice as long as tarsal claw, metauncus small. Abdomen: sternite 1 longer than 2 behind coxal cavity; sternites 3 and 4 equal in length, combined longer than 5; sternite 5 truncate apically; all sternites clothed with clavate, white scales laterally and with narrow, elongate, white scales medially. Pygidium: small. Genitalia: not dissected.   
 Remarks. This species is very distinctive and stands alone from the remainder of this group by its piceous pronotum and fuscous elytra. It is described from a unique, female, poorly, pinned specimen and appears similar to the genus Labaninus in the shape of the profemora, but has the metauncus in the position of Curculio rather than off set as in the male of Labaninus and has a complete second abdominal suture where as abdominal sternites 1 and 2 appear fused medially in Labaninus.   
 Etymology. Named in honor of the collector ‘‘L. Zang.’’
