In general appearance similar to
L
.
rufopunctata rufopunctata
Rougemont, 2000
. Body dark brown to black; each elytron with yellow irregular roundish spot in middle; legs and antennae brown; ocelli, mouthparts, base of antennomeres I–III and tarsi yellow. Habitus as in
Fig. 2
. Measurements of antennomeres (length/width,
holotype
): I: 0.22 × 0.10; II– III: 0.15 × 0.05; IV: 0.14× 0.05; V–VI: 0.15 × 0.05; VII–VIII: 0.16 × 0.05; IX 0.15 × 0.07; X: 0.13 × 0.07; XI: 0.20 × 0.07. Pronotum 1.1 times wider than head. Elytra 1.8 times longer than pronotum.
Male. Aedeagus (
Fig 5
) very long, with median lobe gradually narrowing towards apex; parameres moderately wide, reaching apex of aedeagus; endophallus with moderately long paired parallel structures, with two small slightly curved sclerites in apical part. Aedeagus laterally as in
Fig. 6
.
Comparative notes.
Male and female genital characters of the new subspecies as in
L
.
r. rufopunctata
, but body size, some proportions of the forebody and coloration differ from the
type
form from the mainland
China
(Zhejiang (Moganshan, Hangzhou), Jiangsu (Nanjing), Beijing (Panshan, Yingtaogou); for details see
Rougemont 2000
) as follows: body smaller (

.
rufopunctata
– from 4.40 to 5.00 mm), coloration much paler (body of

.
r
.
rufopunctata
black, legs fuscous black), pronotum slightly wider, elytra slightly wider and shorter. The length of the aedeagus of the larger-body
L
.
r. rufopunctata
is the same (
1.20 mm
) as the new subspecies (one-third shorter in length of body!). The median lobe of the aedeagus of
L
.
r
.
taiwanica
subsp. n.
is somewhat wider, the apex of the aedeagus is slightly narrower, and the apical paired sclerites of the endophallus are slightly longer and not curved compared to that of

Etymology.
The new subspecies is named after
Taiwan
where the
type
series was collected.
Bionomics.
Specimens taken by submerging various edge vegetation into water of a small pond in coniferous forest (Smetana, pers. comm.).
