a sclerotized hair-like projection of the cuticle
present, eye entire/shallowly emarginateemarginate:
notched at the margin
or 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 scapescape:
the first proximal segment of the antenna
≥ segment 3 or 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 subquadratesubquadrate:
not quite a square
or 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 brown, elytral color pattern absent.
Legs: visible tarsomeres: 4, femora clavateclavate:
thickening gradually toward the tip
, rarely slender, protibial spurs: 2, tarsal claws simple.

notched at the margin

shaped like a cylinder, parallel sided
. Pronotumpronotum:
the upper and dorsal part of the prothorax
suboctagonal, slightly constricted at basebase:
the part of any appendage or structure that is nearest the body
; prosternum with intercoxal process very narrow, not expanded posteriorly; anterior coxae moderately prominent, cavities broadly angulate externally, wide open posteriorly; intermediate coxal cavities open to epimera; metepisterna broad in front, narrowed to a point behind.

Similar genera

Hesperanoplium

Differential diagnosis

Can be differentiated from Hesperanoplium by the maxillary and labial palpi being cylindricalcylindrical:
shaped like a cylinder, parallel sided
rather than expanded and triangular. Differs from the Methiini by the short, slender, subequal palpi and shape (globular) of the anterior coxae.

Distribution

Nearctic: eastern California through Great Basin to Texas

Recorded host plants

Pinus monophylla, P. ponderosa

Remarks

Five species. Conifers: H. testaceus.
