Comments.
This species is closely related to
L
.
succinctus
and
L
.
pavettae
. However, it can be differentiated from these by the shape of the pelta, the metanotal sculpture, and differences in length of the pronotal setae. In the
holotype
of
L
.
succinctus
the anteroangulars and anteromarginals are subequal, but in the
holotype
of
L
.
pavettae
the anteroangulars are longer than the anteromarginals. In
L
.
acaciae
the anteromarginals are longer than the anteroangulars. The metanotum has reticulate sculpture and pointed setae in
L
.
succinctus
and
L
.
pavettae
, but has longitudinal lines and expanded setae in
L
.
acaciae
.
