, length of segment I two or three times longer than segment II; cephalic spinescephalic spine:
a spine on the head
present; bucculaebuccula:
an elevated ridge on either side of the first labial segment
closed anteriorly; rostral sulcusrostral sulcus:
shallow furrow on either side of rostrum (labium)
uninterrupted by a transverse carinatransverse carina:
a carina that runs across the body or body part, as opposed to longitudinally
, broadly cordate or enlarged on metasternum; pronotum tricarinatetricarinate:
bearing both median carina and lateral carinae on pronotum
, height of median carinamedian carina:
an elevated ridge located on the midline of the pronotum
equal to or greater than that of lateral carinaelateral carina:
an elevated ridge located on either side of the pronotum
; pronotal hood tectiformtectiform:
tent-like or roof-shaped
, not bulbous, not extending beyond the apex of head; paranotumparanotum:
lateral extension of pronotum; may be carinate, explanate, or reflexed
narrow, expanded throughout with one or two areolaeareola:
a small enclosed space on a surface, such as an area enclosed by veinlets on wings
; spines absent along paranotal margin, anterior margin not projecting anterad; posterior process of pronotumpronotum:
dorsal sclerite of the first thoracic segment
short, with rounded or triangular apex; hemelytrahemelytron:
one of the basally thickened forewings of Hemiptera
with claval areaclaval area:
parallel-sided and sharply pointed anal area of hemelytron
weakly developed, almost entirely covered by posterior margin of pronotumpronotum:
dorsal sclerite of the first thoracic segment
; costal areacostal area:
area of the costa delineated by the first longitudinal vein of the wing, usually running along the anterior margin
broad, with 3 or more rows of areolaeareola:
a small enclosed space on a surface, such as an area enclosed by veinlets on wings
; discoidal areadiscoidal area:
area of the forewing posterior to the subcostal area
level, discoidal cell closed behind, very short, not extending beyond basal one-third of hemelytrahemelytron:
one of the basally thickened forewings of Hemiptera
; hypocostal laminaehypocostal lamina:
a ridge produced ventrally along costal margin
not extending beyond the apex of abdomen; distance between procoxae narrower than distances between meso- and metacoxae (Drake and Hambleton 1946bDrake and Hambleton 1946b:
