Description. Male (Figs 14, 14h, 16–18): length: 8.4–10.8 mm, humeral width:
2.3–3.0 mm. Female (Figs 12–13, 15, 15h): length:10.5–13.0 mm, humeral width:
3.2–3.9 mm. Body black, in part provided with thick, white (dry and old specimens,
Figs 14–15) to yellow (alive or fresh specimens, Figs 12–13) pubescent maculae.
Head black, frons with two white or yellow stripes (almost fused in male, Fig.
14h) from inner side of antennae insertions along eyes and genae to clypeus (Fig.
15h), temple white or yellow (Fig. 12a), vertex with two parallel stripes (usually
fused) between upper eye lobes; antennae black, scattered with short, black bristles
on undersides of first seven segments. Prothorax with a medial white or yellow
stripe, each side white or yellow except a transverse black vitta (Fig. 12a). Scutellum
white or yellow. Elytra without surural stripes, each disc with 5 white or yellow
maculae: two spots at basal 1/4, the one near suture much bigger than the one near
margin; a moderate sized oval spot at middle, near suture; the fourth one smaller
than middle one, closer to lateral margin than to suture, at the centre of apical half;
an oblique transverse band just before apex. Ventral surface covered with dense
white or yellow pubescence, thinly so along middle. Legs black, thinly pubescent.
Pronotum and elytral bases with sparse, erect, black bristles.
Head hardly broader than prothorax, deeply, and in part closely punctured,
feebly concave at vertex. Eyes deeply emarginate, inferior eye lobes subequal to
(female) or 2 times as high as (male) genae below it, width much less than half of
frons. Antennae longer than body, male longer than female; scape thicknened apical
without cicatrix not a ridge; antennomere ratio (male): 12 : 3 : 18 : 15 : 14 : 13
: 13 : 12 : 12 : 11 : 12; (female): 13 : 3 : 21 : 17 : 16 : 15 : 14 : 14 : 13 : 12 : 13.
Prothorax almost as broad as long (male) or broader than long (female), swollen
laterally before middle, disc convex and somewhat deeply and closely punctured.
Elytra rounded at humeri, slightly narrowed apically, each with 2 humeral longitudinal
ridges beginning after humeri and reaching close to apex, truncated apically,
with short and small teeth at the suture, long and sharp spine at the outer angle,
surface with coarse and irregular punctures. Legs stout, middle tibiae grooved, hind
femur reaching middle to apex of third abdominal segment, first hind tarsal segment
longer than (male), or nearly as long as (female) following two segments
combined. Male claws: the anterior claws of the mid tarsi with a short (half of the
normal claw) tooth (Figs 17–18), fore and hind tarsi with simple claws (Fig. 16).
Female claws simple.
Male genitalia (Figs 19–21): Tegmen length about 1.9 mm; lateral lobes slender,
each about 0.6 mm long and 0.2 mm wide, with finely haired ridge at the base (in
ventral view, Fig. 20), apex obliquely rounded and with fine setae which are shorter
than lateral lobes; ringed part elbowed in the widest portion, converging; basal piece bifurcated distally; median lobe plus median struts moderately curved, subequal to tegmen
in length; the median struts about one half of the whole length of median lobe;
dorsal plate shorter than ventral plate; apex of ventral plage (Fig. 20) pointed, apex not
so sharp and not curved to right side; median foramen elongated with a projection in
lateral view (Fig. 19b); internal sac about 3 times as long as median lobe plus median
struts, with 4 pieces of basal armature, 2 bands of supporting armature and 3 rods; the
two longer rods each about 1.2 mm, shorter than tegmen, the short middle rod about
0.7 mm long. Ejaculatory duct single. Tergite VIII (Fig. 21c) longer than broad, apex
rounded, setae near lateral corner dense and long, and sparse and short around middle.
Female genitalia (Figs 22–23): spermathecal gland located at the base of spermathecal
capsule. Spermathecal capsule with a curved basal stalk and a rounded apical orb,
stalk more than twice the length of capsule.

Diagnosis. Differs from long spine elytron (Fig. 35) species G. laodice Thomson,
1879 (Fig. 27) and G. subalcyone Breuning, 1964 (Figs 28–29) in elytron having five
white or yellow maculae instead of six, and their positions different. Differs from G.
coomani and other short tooth elytron (Fig. 34) species in elytral apex having a long
and sharp spine at the outer angle. Differs from G. coomani also in male terminalia:
tergite VIII with apex rounded instead of truncated; lateral lobes of tegmen slender, the
length ratio of lateral lobes to tegmen much bigger; apex of ventral plate not so sharp
and not curved to right side.
