Etymology.
The species is named so, as it has bright green spots on pronotum and hemelytra. From Latin “viridis” means “green” and “macula” means “mark” or “spot”.

Differential diagnosis.
The two known species differ in male genitalic structure. In
W. viridimaculatus
the dorsal process of the phallotheca is semioval and smooth (
Fig. 6
A), the apex of the left paramere is straight (
Fig. 6
E), and the large endosomal spicule has two processes (
Figs. 6
B, C). In
W. mchughi
the dorsal process of the phallotheca is oval and serrate (
Fig. 3
A), the apex of the left paramere is curved downwards (fig, 3E), and the large endosomal spicule has three processes (Figs. B, C). Externally the species can be distinguished by the relative length of the labial segments. In
W. viridimaculatus
LII
is almost as long as LI and
LIII
is longer than
LII
, whereas in
W. mchughi
LII
is longer than segment I and
LIII
is as long as segment II.
Description.
Male
. Total length 4.0–4.4.
Head
: yellowish with vertex pale green, reddish pattern on head as in generic description; spots on dorsal side sometimes reddish brown.
Eye:
brownish with reddish tinge.
Antennae
: AI uniformly coloured or with pale brown indistinct band basally; AII pale green with brownish bands as in generic description; AIII gradually changing colour from pale green basally and pale brown apically; AIV uniformly pale brown or pale green at base.
Labium
: LII pale yellow or pale green; LIII uniformly yellow; LIV brownish; pale brown at base.
Pronotum:
as in generic description, with yellow stripes distinct, sometimes with bright green markings.
Scutellum:
pale green, colour pattern as in generic description.
Mesoscutum
: whitish or pale green, colour pattern as in generic description.
Thoracic pleura
: mesopleuron uniformly yellow, or upper part yellow and inferior part reddish.
Legs:
tibiae yellow with tiny reddish markings, sometimes with brownish apex; tarsal segments I and III brownish; segment II yellow or pale brown.
Hemelytron:
as in generic description, with or without bright green markings. VESTITURE: As in generic description. STRUCTURE: Mostly as in generic description; labium reaching middle of abdomen; LII almost as long as LI and LIII longer than LII; body 4.5–5.0x as long as width of pronotum; vertex 2.2–2.8x as wide as eye; segment II 1.7–1.9x as long as width of head, 1.1–1.2x as long as width of pronotum; pronotum 1.9–2.4x as wide as long and 1.5–1.6x as wide as head. GENITALIA: left paramere with apex straight (
Fig. 6
E); phallotheca with semioval and smooth dorsal process (
Fig. 6
A); large endosoma spicule with two processes (
Figs. 6
B, C).
Female
.
Total length 2.8. Colouration, vestiture and genitalia as in generic description. STRUCTURE: As in generic description; body 3.8x as long as width of pronotum; vertex 3.2x as wide as eye; segment II 1.7x as long as width of head, 1.3x as long as width of pronotum; pronotum 1.8x as wide as long and 1.4x as wide as head.
