Acalypta

Taxonomy

Acalypta Westwood, 1840

Type species: Tingis carinata Panzer

Diagnostic characters

Several morphological characters that usually remain constant within tingid genera vary considerably between polymorphic forms within this Holarctic genus. The polymorphic differences include size and convexity of the pronotumpronotum:
dorsal sclerite of the first thoracic segment
, spacing of the coxae, form and length of the hemelytrahemelytra:
one of the basally thickened forewings of Hemiptera
, presence or absence of the hindwings, and general habitus.

Characters diagnostic for the genus: head short, clypeus not surpassing apical half of first antennal segment; cephalic spinescephalic spines:
a spine on the head
present, less than 5 spines; antenniferous processesantenniferous processes:
the socket in which antenna is inserted in the head; also known as antennophore, antennal tubercles, or antennal process
prominent; pronotumpronotum:
dorsal sclerite of the first thoracic segment
uni- or tricarinatetricarinate:
bearing both median carina and lateral carinae on pronotum
; paranotumparanotum:
lateral extension of pronotum; may be carinate, explanate, or reflexed
widely expanded, not reflexedreflexed:
bent or curved backwards, as in a reflexed paranotum
; pronotal hoodhood:
term used to describe the modified anterior area of the pronotum, which is sometimes tectiform and sometimes bulbous, with numerous intermediate conditions.
tectiform, not bulbous; hemelytrahemelytra:
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
; discoidal areadiscoidal area:
area of the forewing posterior to the subcostal area
flat, extending beyond the middle of hemelytrahemelytra:
one of the basally thickened forewings of Hemiptera
