Body narrow and elongate, head short, clypeus not surpassing apical half of first antennal segmentantennal segment:
subdivisions of the antennae, denoted by constrictions. All Tingidae have 4 segments.  
; antennae subequal to or shorter than the body, segment I five times or more longer than segment II; cephalic spinescephalic spine:
a spine on the head
present, confined to occipital spinesoccipital spine:
a cephalic spine (one of a pair) located on the occiput or arising a short distance forward so as to be between the eyes
and dorsomedial spinedorsomedial spine:
a single spine on the midline of the head
; 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)
parallel, not constricted, uninterrupted by a transverse carinatransverse carina:
a carina that runs across the body or body part, as opposed to longitudinally
; pronotum tricarinatetricarinate:
bearing both median carina and lateral carinae on pronotum
, lateral carinaelateral carina:
an elevated ridge located on either side of the pronotum
extends throughout the pronotumpronotum:
dorsal sclerite of the first thoracic segment
, height of median carinamedian carina:
an elevated ridge located on the midline of the pronotum
equal to 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
carinate or narrow, with 1-2 rows of areolaeareola:
a small enclosed space on a surface, such as an area enclosed by veinlets on wings
, not reflexedreflexed:
bent or curved backwards, as in a reflexed paranotum
, oriented subvertically, spines absent along paranotal margin, anterior margin not projecting anterad; 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
narrow, with 1-2 rows of areolaeareola:
a small enclosed space on a surface, such as an area enclosed by veinlets on wings
; discoidal cell level, short, not reaching the middle of hemelytrahemelytron:
one of the basally thickened forewings of Hemiptera
