Type material.

(2 ♂♂). Holotype: CHINA: ♂: 'China: Guangxi, Hechi City, Mulun N. R. (木论自然保护区), 25°12'14"N, 108°5'46"E, mixed leaf litter, sifted, 460 m, 27.VII.2015, Chen, He, & Hu leg.' (SNUC). Paratype: China: 1 ♂, same label data as holotype, (SNUC).

Diagnosis of male.

Length 2.75-2.77 mm; antennomeres IX–XI elongate, lacking modification; long metaventral processes narrowed apically; protibia with acute apical spine; metacoxa with large, apically narrowing and blunt ventral projection.


Male (Figure 7B). Length 2.75-2.78 mm. Head slightly longer than wide, HL 0.59-0.60 mm, HW 0.52-0.53 mm; eyes small, each composed of about 18 facets. Antennal scape about 4.0 times as long as wide, antennomeres V–VII slightly longer than II–IV and VIII, antennomeres IX–XI simple (Figure 9A). Pronotum (Figure 9B) about as long as wide, PL 0.55-0.56 mm, PW 0.55-0.56 mm. Elytra much wider than long, EL 0.66-0.70 mm, EW 0.93-0.95 mm. Metaventral processes (Figure 9C) long, narrowed apically, with short, distinct protuberance above metacoxae. Protrochanter and profemur simple (Figure 9D); protibia with small but distinct spine (Figure 9E) at apex; mesotrochanter and mesofemur simple (Figure 9F); metacoxa (Figure 9G) with blunt, apically narrowed ventral projection. Abdomen slightly wider than elytra, AL 0.93-0.94 mm, AW 0.97-0.98 mm; tergite IV about twice as long as tergite V; sternite IX as in Figure 9H. Length of aedeagus (Figure 9 I–K) 0.37 mm; median lobe asymmetric at apex, narrowing apically; parameres strongly curved in lateral view.

Female. Unknown.


China: Guangxi Province (Figure 11B).


The new species is named after the type locality, i.e., Mulun Nature Reserve.

Comparative notes.

The new species is placed as a member of the L. chinensis  -group based on the simple male antennomeres IX–X. The form and proportions of antennomeres IX–XI are similar to L. chinensis  ( Löbl) and L. inornatus  Yin & Li. However, both known species lack a projection on the ventral margin of metacoxa in the males, where there is a large, apically narrowed projection for the new species.
