Genitalia examined in
three males
and
two females
.
DIAGNOSIS. A fairly slender species with pronotum uniform red to black; elytra subparallel-sided, black, with a fairly wide transverse median band which is alternatively dentate anteriorly and posteriorly. Head entirely red to black between pronotum and frontoclypeal suture, with supra-antennal plates, sides of neck, and often also distinct to vague subtransverse patch on a level with anterior margin of eye pale. Female tergite VII with 9–12 straight apical setae, sternite VII mostly bisetose in male. Median lobe of aedeagus (
Figs 29–30
) with apex strongly bent ventrad, pointed, more or less coarsely sculptured ventrally. Internal sac without right distal basal bulb, in lateral view with a preapical frontal bulb.
REDESCRIPTION. BL
15–17.7 mm
(in specimens examined). Body pattern as in
Figs 98–102
: elytron with humeral spot small or medium-sized; transverse median band reaching lateral margin or (mostly) not, more or less strongly dentate, often with teeth blunt or rounded apically; pale lateral margin missing to rather wide, merged into pale apical margin yet not reaching humerus. Head and pronotum glabrous, without or with several individual short setae, with setigerous punctures imperceptible.
Pronotum rather small and short, as wide as or barely wider than long, subcordate, broadest two fifths from apex, with sides subsinuate a fifth from base and rounded before; basal angles nearly right, with extreme apices blunted. Base slightly wider than apex. Lateral bead and groove distinct throughout.
Abdomen (
Figs 2
,
12
): Tergite VII punctate as in
S. javanus
, larger punctures being sparser, finer and unevenly spaced in some males.
Internal sac of aedeagus (
Figs 29–30
) in lateral view has body straight, with microtrichia moderately developed over the body which is incrassate medially and thence slightly separated from proximal basal bulbs; these in anterodorsal view more or less projecting laterad; left distal basal bulb only present; it is triangular, about as large as apex of median lobe in dorsal view.
Female gonocoxite IX (
Fig. 64
) and reproductive tract as for
S. javanus
.
GEOGRAPHIC DISTRIBUTION. Throughout Hindustan (including
Sri Lanka
,
Pakistan
,
Nepal
, and
Bhutan
) and western Indochina east to
Laos
and south to the Malay Peninsula. The record of the species in
Laos
[
Andrewes, 1930
] makes its occurrence not improbable in central or northern
Vietnam
.
HABITATS AND HABITS. No exact data.
COMMENTS. According to the descriptions,
S. lissoderus
is distinctive from
S. picicollis
in only having the head and pronotum entirely pale (
vs
. infuscated). My comparison of the
holotype
of
S. lissoderus
and a
syntype
of
S. picicollis
from
Siam
, as depicted in
Venugopal and Thomas [2019
:
Figs 2A and 2C
, respectively] with both each other and the specimens listed above has revealed no differences except in body colour. Because diferently coloured males from one and the same population as well as from different populations have similar aedeagi, the two names are here considered as conspecific and only referred to as different colour morphs, either pale (forma ‘lissodera’) or melanistic (forma ‘picicollis’).
