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:

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 blunt tubercule. 
Prosternum: prosternal process not 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
, elytral color black or metallic, elytral color pattern absent. 
Legs: visible tarsomeres: 4, femora slender, rarely clavateclavate:
thickening gradually toward the tip
, protibial spurs: 2, tarsal claws simple. 

Form elongateelongate:
much longer than wide
, slender, somewhat flattened. Eyes feebly embracing antennal insertions; 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
narrow, third segment distinctly longer than fourth, last segment of male appendiculateappendiculate:
bearing appendages
or divided, of female normal. Pronotumpronotum:
the upper and dorsal part of the prothorax
wider than long, sides rounded or obtusely angulate at middle, constricted at basebase:
the part of any appendage or structure that is nearest the body
; intercoxal process of presternum short, narrow, pointed behind; mesosternal processmesosternal process:
a prolongation of the mesosternum extending between the mesocoxae
large, narrowing and obtusely rounded behind. Femora slender; first segment of posterior tarsitarsus:
the leg segment distal to the apex of the tibia, bearing the pretarsus; consists of one to five tarsomeres (including pretarsus)
slender, more than twice as long as broad (Linsley 1964Linsley 1964:

Similar genera

Batyle, Turanium

Differential diagnosis

Batyle is superficially similar to Pronocera, but 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
are dense with erect setaeseta:
a sclerotized hair-like projection of the cuticle
and the procoxal cavities are angulate externally. Turanium has a bald groove under tarsomeres 1–3 while Pronocera is completely setosesetose:
furnished or covered with setae or stiff hairs
.

Distribution

Holarctic conifer forests

Recorded host plants

New World: Picea spp., Pinus spp.

Old World: Abies, Larix, Pinus, Picea

Remarks

Three species. The genus Pronocera is found in areas with conifer forest in the Holarctic and all species feed on conifers.
