Type material.

Holotype: ♂ (MHBU), China, Yunnan, Pingbian, Daweishan, 1900 m, 24.V.1996, leg. L. Y. Zheng.

Diagnosis.

The new species seems similar to L. putzi in the coloration, but differs in the following characters: fore and mid legs with a digitiform tooth on each anterior claw in male, while on both anterior and posterior claws in the latter; aedeagus with dorsal plate of each paramere wide (Fig. 9E ) and moderately longer than ventral process (Fig. 9F ), while narrower (Fig. 7B ) and distinctly long (Fig. 7C ) in L. putzi ; laterophyse feebly furcate at apices (Fig. 9F ), while acute in the latter (Fig. 7C ).

Description.

Male (Fig. 19C ). Head, prothorax and legs orange, mandibles dark brown at apices, antennae black, except for bases of antennomeres I yellow, pronotum with a small and round black marking in center of disc, scutellum yellow, elytra pale yellow and almost transparent, each with a black longitudinal band along apical two-thirds part, leaving a long triangular area pale yellow along suture, legs darkened at tarsi, meso- and metasterna and abdomen black, terminal two abdominal ventrites and sternites pale yellow. Body densely covered with yellow recumbent pubescence.

Head feebly narrowed behind eyes, surface densely and finely punctate; eyes moderately large and protruding, head width across eyes slightly wider than anterior margin of pronotum; antennae filiform, extending to apical third length of elytra when reclined, antennomeres II shortest, ~ 2 × longer than wide at apices, IV-XI nearly parallel-sided, each with a short smooth impression near apical part of outer margin, IV longest.

Pronotum subquadrate, feebly longer than wide, anterior margin feebly arcuate, lateral margins subparallel, posterior margin nearly straight, anterior angles obtuse-rounded, posterior angles nearly right-angled, disc convex on posterolateral parts, surface finely and feebly sparsely punctate than that on head.

Elytra ~ 4.4 × longer than pronotum, 3.12 × longer than width across humeri, outer margins nearly parallel, disc semi-lustrous, coarsely and densely punctate.

Legs slender, fore and middle legs with a digitiform tooth on each anterior claw, and hind claws simple.

Aedeagus: basal piece slightly longer than dorsal plate of each paramere (Fig. 9D-F ); ventral process of each paramere slender, slightly expanded at apices, slightly bent inwards and approaching to each other in ventral view (Fig. 9D ), inclining ventrally in lateral view, with apices slightly curved dorsally (Fig. 9F ); dorsal plate obviously longer than ventral process of each paramere, with apical margins rounded (Fig. 9E ); laterophyse feebly longer than ventral process, with apices bifurcate and directing dorso-outwards (Fig. 9D, F ).

Female. Unknown.

Body length: 10.2 mm; width: 2.2 mm.

Distribution.

China (Yunnan).

Etymology.

The specific name is derived from the Latin mimus (imitator), referring to its similarity to L. putzi Švihla, 2011.
