Mucro bidentate; tip of basal spine reaching apex of subapical tooth; distal smooth section of dens slightly longer than mucro in length (Fig. 19 E View Figure 19 ).

Etymology.

The name is composed of the locality name Wuxi plus the Latin suffix “ - ensis, ” meaning pertaining or originating, referring to its type locality, Wuxi County.

Habitat.

Found in litter of subtropical forests, mainly composed of leaves of Buxus sinica , Ilex yunnanensis , Pinus armandii , and Rosa corymbulosa .

Remarks.

The new species can be easily distinguished from other species by its color pattern, although it is somewhat similar to the New Zealand species L. dorsalis ( Salmon, 1941) . However, only the posterior part of Abd. IV is brown pigmented in the former, and almost the whole part of Abd. IV is pigmented in the latter. The main differences between the new species and the other Chinese species of the genus in chaetotaxy are listed in Table 3 View Table 3 .
