Carphobius

Type species

Carphobius arizonicus Blackman

Adapted from Wood 1982, p. 369-371

Diagnosis

Carphobius resembles Phloeosinus Chapuisin in the subtribe Phloeosinina, but it can be distinguished by the 6-segmented antennal funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
and the lack of a visible scutellumscutellum:
a shield-like bony plate or scale, as on the thorax of some insects
.

Description

Species in this genus range from 1.6 to 2.1 mm in length and are approximately 2.2 times as long as wide. Their color is usually dark brown. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is wider than long and unarmedunarmed:
having no granules, teeth, tubercles, spines, or other protective structures
. The scutellumscutellum:
a shield-like bony plate or scale, as on the thorax of some insects
is not visible. The declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
is bisulcatebisulcate:
a structure that is grooved in two places, often contiguous at both sides of a central line
in C. arizonicus of the United States and convex in the Mexican and Guatemalan species, armedarmed:
having a sclerotized surface structure, giving a rough texture; may serve as defense
in C. arizonicus with a row of pointed tuberclestubercles:
stiff, pointed, tapered processes on the surface of the integument, usually shorter than a spine
, not so in the other species. The vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
consists of light-colored, hair-like setaehair-like setae:
setae that are thin and similar to a hair
. The anterior margin of the compound eye is emarginateemarginate:
notched or indented
. The scapescape:
the first and basal segment of the insect's antennae
is approximately as long as the 6-segmented funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
, and the ovateovate:
egg shaped, with the narrow end apically
clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
has 3 straight-transverse suturessutures:
a seam or seam-like line of contact between two sclerites or hardened body parts immovably connected
, the first being septateseptate:
having a septum or septa
. 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
.
