Comment:
The aedeagus of the above material is identical to the illustrations of the aedeagus provided with the original description of
L. sibynium
from Sichuan. According to
ZHENG (1988)
, the reddish elytral spot occupies approximately one third of the elytral surface, whereas it is very small, sometimes even indistinct, in the material from
Taiwan
, but this difference is probably an expression of intra- rather than interspecific variation.
The species is separated from all other
Lobrathium
species
known from
Taiwan
by the sexual characters (
Figs 91-96
), from most species also by the slender and long elytra, which are approximately as long as the pronotum.
The above specimens were collected from moss and vegetation at the margin of ponds in an old coniferous forest, in old flood debris and leaf litter on river banks, as well as by sifting leaf litter on a road margin in a mixed forest at altitudes of
1550-2200 m
.
