Phloeotribus

Type species

Hylesinus oleae Fabricius

Adapted from Wood 1982, p. 256-283

Diagnosis

Phloeotribus is unique among the scolytinae in having a pseudolamellatepseudolamellate:
an antennal club composed of opposing leaf-like surfaces which are only partially separated
club.

Description

Their size varies from 1.2 to 4.0 mm in length, and their body proportions vary as well. Their color ranges from dark brown to black. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is wider than long, sometimes armedarmed:
having a sclerotized surface structure, giving a rough texture; may serve as defense
by granulesgranules:
a small grain-like elevation
. The scutellumscutellum:
a shield-like bony plate or scale, as on the thorax of some insects
is small. The declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
is convex and has granulesgranules:
a small grain-like elevation
. The anterior margin of the compound eye is entire. The scapescape:
the first and basal segment of the insect's antennae
is longer than the 5-segmented funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
and has long setaesetae:
a hollow, often slender and hair-like cuticular projection
. The clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
is pseudolamellatepseudolamellate:
an antennal club composed of opposing leaf-like surfaces which are only partially separated
and in some species it can give the impression of having 2 suturessutures:
a seam or seam-like line of contact between two sclerites or hardened body parts immovably connected
. The procoxaeprocoxae:
extra segment occasionally preceding coxa (hip joint) of the first or anterior pair of legs of arthropods
are contiguouscontiguous:
sharing an edge or boundary; touching
.
