Type
species:
Luciola circumdata
(
Motschulsky 1854
)
designated by
Ballantyne & Lambkin 2009: 30
.
Diagnosis.
A genus with relatively large species (usually
10 mm
or longer) having a broad pronotum with laterally divergent margins, and convex sided elytra which are often brightly coloured, many with dark brown to black elytra having pale margins. Known larvae are terrestrial. Males distinguished from all other
Luciolinae
by the asymmetrical T8 which is emarginate on its left side (
Ballantyne & Lambkin 2009
fig. 7); all but one species have bipartite LO in
V7.
Females are macropterous and those examined have no bursa plates; in two species the median oviduct plate is subtriangular in outline; larvae have laterally explanate tergal margins (
Fu
et al.
2012a: 22
).
Remarks
.
Asymmetricata
was erected for two species transferred from
Luciola
(
As. circumdata
Motsch. 1854
from
Thailand
and
Cambodia
, and
As
.
ovalis
[
Hope 1831
] from
India
) and characterised primarily by the asymmetrical male abdominal T8 (
Ballantyne & Lambkin 2009: 30
). The species were keyed and distinguished by the nature of the light organs in
V7
(either bipartite or entire). Two further species with a similar configuration of T8 and bipartite LOs in
V7
viz.
As
.
humeralis
(
Walker 1858
)
comb. nov.
and
As
.
bicoloripes
(
Pic 1927
)
comb. nov.
are transferred from
Luciola
. Three species (
Luciola doriae
Olivier 1885
,
L
.
impressa
Olivier 1910b
and
L. notatipennis
Olivier 1909a
) are synonymised with
As
.
humeralis
comb. nov.
However, the variability of the dorsal colour patterns indicated below could indicate further variability
As
.
humeralis
comb. nov.
(interpretations were made from dead museum specimens where it may be difficult to interpret the original colour pattern). Assessing this variability requires examination of aedeagal and aedeagal sheath patterns.
Ballantyne & Lambkin (2009)
suggested the possibility of a gradation from entire to bipartite LO in
V7
because of the anterior emargination of the LO in
V
7
in
As. circumdata
. On the basis of specimens examined here it appears that the LO in
V7
exists in two distinct forms either bipartite or entire (see below) but that there is no evidence of a gradation between the two different forms.
