Readily identified by relatively fine, sparse punctuation on elytra, with distance between each puncture greater than width of one puncture (
Figs 19, 20
). The numerous small tufted tubercles with black hairs longitudinally along each costa, giving the entire elytra a distinctly spotted appearance. Elytra with a uniform yellowish colour on a dark brown integument giving a more or less green lustre, interrupted with a transversal oblique black band (or squareshaped spots) below middle but not covering the area between costae 1 and 2. The posterior margin of tergite VII in the male notched in the middle, with short, yellowish hairs. Similar to
L. ocellatus
,
L. holzschuhi
and
L. multipunctellus
but different in having sparse and weak punctures on elytra, short and blunt lateral spines on pronotum, distinctly spotted costae, and lack of whitish pubescence on elytra. Male genitalia distinctly different from the other 3 species mentioned earlier. Crescent-shaped sclerites at proximal end of basal segment very fine, the fork-like median sclerite well developed and similar to the median sclerite of
L. campbelli
.
Examined male: length
9.1 mm
, width
3.1 mm
. HT male: length
9.5 mm
, width
3.5 mm
according to
Hayashi (1974)
.
Aedeagus:
Approx.
1.5 mm
long, relatively slender, narrowed and weakly curved towards apex, dorsal ridge not wider than the ventral ridge towards apex (
Fig. 67
). Crescent-shaped sclerites at proximal end of basal segment very fine, and median fork-like sclerite inside the internal sac well developed (the sclerotized shaft weakly twisted); surrounding intersegmental membrane with coarse, square-shaped micro-reticulation (
Fig. 44
).
Tegmen:
Approx.
1.8 mm
, parameres slender and slightly flattened dorso-ventrally, well separated medially along inner margin and towards apex (
Fig. 81
). Apex evenly rounded along entire posterior margin, with fringes made up of relatively long, yellowish hairs on the edge of apex on the last 1/3 of the parameres. Very weak micro-reticulation towards apex. Base of tegmen extended and strongly curved dorso-ventrally on middle.
Tergite VIII:
Approx.
0.65 mm
long, yellowish with brownish pigmentation on entire surface. Anterior part with short, fine, yellowish hairs distally towards the posterior margin (
Fig. 95
). Entire surface with weak, but clearly visible, micro-reticulation.
Remarks:
This species is endemic to the island of
Taiwan
(
Fig. 99
).
