Body length: 13–33.3mm.
Eyes: eye interommatidial setaeseta:
a sclerotized hair-like projection of the cuticle
present, eye deeply emarginateemarginate:
notched at the margin
> half width, eye ommatidial density coarse.
AntennaeAntenna:
in larval and adult insects, paired segmented appendages, borne one on each side of the head, functioning as sense organs and bearing a large number of sensilla
: antennal length reaches between basebase:
the part of any appendage or structure that is nearest the body
and end of elytraelytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
or reaching/surpassing end of body, antennal flagellar segments elongateelongate:
much longer than wide
, scapescape:
the first proximal segment of the antenna
smooth/punctate at apexapex:
end of any structure distad to the base
, antennal segment 3 > scapescape:
the first proximal segment of the antenna
.
Pronotumpronotum:
the upper and dorsal part of the prothorax
: pronotumpronotum:
the upper and dorsal part of the prothorax
shape transversetransverse:
broader than long
, pronotumpronotum:
the upper and dorsal part of the prothorax
lateral armature absent or acute spinespine:
a protuberance with an acute (sharp) distal end
.
Prosternum: prosternal process dilated at apexapex:
end of any structure distad to the base
, procoxal cavities open posteriorly.
ElytraElytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
: elytral length reaching or close to end of abdomen, elytral apicesapex:
end of any structure distad to the base
rounded or truncatetruncate:
cut off squarely at the tip
, emarginateemarginate:
notched at the margin
or with tooth or spinespine:
a protuberance with an acute (sharp) distal end
, elytral color black, brown, or reddish, elytral color pattern present or absent.
Legs: visible tarsomeres: 4, femora clavateclavate:
thickening gradually toward the tip
or slender, protibial spurs: 2, tarsal claws simple.
Mallocera
Eurysthea is variable in many of these characters but can be diagnosed by the brown to reddish color, usually a yellowish maculamacula:
a spot or mark
on the elytraelytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
, erect white setaeseta:
a sclerotized hair-like projection of the cuticle
on the elytraelytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
and usually femora, and often (but not in all species) a lateral pronotal spinespine:
a protuberance with an acute (sharp) distal end
positioned on the posterior third.
