Phloeotribus

Type species

Hylesinus oleae Fabricius

Adapted from Wood 1982, p. 256-283

Diagnosis

Phloeotribus is unique among the Hylesinini in having a pseudolamellatepseudolamellate:
an antennal club composed of opposing leaf-like surfaces which are only partially separated
clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
.

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
.
