Diagnosis. The new species is closely allied to L. thaianus Maruyama, 2008 ( Fig. 1B View FIGURE 1 ) from Thailand in general habitus. L. sinicus sp. nov. can be readily separated from L. thaianus by the slenderer 1 st dorsal antennal denticle, the slightly longer antennal 2nd dorsal denticle, shoulders of pronotum more convex and metatibia almost straight ( Fig. 2C View FIGURE 2 ).
Description. Body ( Fig. 1 View FIGURE 1 ) 4.66–7.12 mm; reddish-brown, but mouthparts and legs slightly paler.
Head ( Fig. 1 View FIGURE 1 ) with shallow longitudinal groove along the midline; frons almost rounded, slightly convex apically; temples weakly protruded laterad; dorsal surface sparsely covered with minute, recumbent setae; eyes large, somewhat prominent; neck narrow, strongly constricted.
Antennae ( Fig. 2A, B View FIGURE 2 ) with segment I parallel-sided; antennal club not articulated except for 1 st article ; posterior margin with five produced denticles, 2nd to 5th dorsal denticles apically with short trichome brush; anterior margin with 1st to 4th projections shallowly emarginate, 5th ventral projection small, sometimes almost fused with 4th ventral projection ( Fig. 2B View FIGURE 2 : arrow), 6th ventral projections minutely convex; each projection with a few short setae at apex; surface sparsely covered with minute, recumbent setae.
Pronotum ( Fig. 1 View FIGURE 1 ) broad, about 2.13 times as wide as long; distinctly wider than head; divided by a transverse cleft; without longitudinal groove; shoulders gently convex; lateral projection well developed, rounded at apex; disc sparsely covered with minute, recumbent setae.
Elytra ( Fig. 1 View FIGURE 1 ) with 7 to 12 pairs of long setae on lateral margins of apical half; shoulders well protruded; surface sparsely covered with minute, recumbent setae.
Legs ( Figs. 1 View FIGURE 1 , 2 View FIGURE 2 C-D) thin; tibiae nearly straight; tarsi slender, sparsely covered with short setae.
Male. Pygidium with sharp edge, with a few short setae at apex; disc smooth, sparsely covered with minute, recumbent setae. Aedeagus shaped as in Fig. 2E View FIGURE 2 .
Female. Pygidium with a more pronounced triangular shape.
Measurements. BL, 4.66–7.12; HW, 1.22–1.57; ACL, 1.26–1.73; PL, 0.72–1.02; PW, 1.70–2.18; EL, 3.50–4.84.
Etymology. Name after China.
Distribution. China (Guangdong, Guangxi, Yunnan).
Biology. Individuals of Lebioderus sinicus were collected from colonies of Carebara ant( Fig. 5A View FIGURE 5 ). The ant nests were located under rock or at the bottom of trees and most adults were found at chambers containing ant larvae. The adults were not injured by the alarmed ants. One specimen from Wutongshan ( Fig. 5B View FIGURE 5 ) was found under the streetlight at night.
Host ant. Carebara sp.
