Nothorhina

Subfamily

Spondylidinae

Diagnosis - adult

Body length: 7–13mm. 
Eyes: eye interommatidial setaeseta:
a sclerotized hair-like projection of the cuticle
present, eye entire/shallowly emarginateemarginate:
notched at the margin
, 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
, 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 scapescape:
the first proximal segment of the antenna
≥ segment 3. 
Pronotumpronotum:
the upper and dorsal part of the prothorax
: pronotumpronotum:
the upper and dorsal part of the prothorax
shape longer than wide, pronotumpronotum:
the upper and dorsal part of the prothorax
lateral armature absent. 
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 brown, elytral color pattern absent. 
Legs: visible tarsomeres: 4, femora slender or robust, protibial spurs: 1, tarsal claws simple.

Characterized by narrow elongateelongate:
much longer than wide
body, oval nonemarginate eyes, and not very long thin 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
. Pronotumpronotum:
the upper and dorsal part of the prothorax
elongateelongate:
much longer than wide
, with almost parallel sides, and sharp median longitudinal, slightly punctatepunctate:
set with fine, impressed points or punctures appearing as pin-pricks
prominence (Cherepanov 1988).

Tetropium

Differential diagnosis

The parallel-sided, longitudinally rectangular pronotumpronotum:
the upper and dorsal part of the prothorax
with medial prominence is diagnostic. Can be differentiated from Tetropium by the undivided setosesetose:
furnished or covered with setae or stiff hairs
eyes and single protibial spur.

Distribution

Palearctic conifer forests

Recorded host plants
