Type species

Cryptocarenus diadematus Eggers

Adapted from Wood 1982, p. 911-915

Diagnosis

Cryptocarenus is similar to Pityophthorus Eichhoff but distinguished from it by the overall smooth appearance, with virtually all vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
absent or greatly reduced.

Description

The length of the females ranges from 1.4 to 3.0 mm while the males are approximately one third smaller, and both sexes are 2.6 to 2.7 times as long as wide. Their color ranges from yellowish or reddish brown to dark brown. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is as long as wide, with asperitiesasperities:
pertaining to surface roughenings or dot-like elevations that are not pointed
on its anterior slope and the anterior margin armedarmed:
having a sclerotized surface structure, giving a rough texture; may serve as defense
by 8 to 14 teeth or serrationsserrations:
a series or set of saw-like teeth or notches
. The scutellumscutellum:
a shield-like bony plate or scale, as on the thorax of some insects
is small and flush with the elytraelytra:
the two external and hardened or sclerotized forewings of adult Coleoptera, often appearing leather-like in texture
. The declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
is convex, and the vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
is rare and consists of short, erect, hair-like setaehair-like setae:
setae that are thin and similar to a hair
and is unarmedunarmed:
having no granules, teeth, tubercles, spines, or other protective structures
. The anterior margin of the compound eye is deeply emarginateemarginate:
notched or indented
. The scapescape:
the first and basal segment of the insect's antennae
is elongate with a 5-segmented funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
. 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 oval, with two procurvedprocurved:
pertaining to structure (antennae, setae) which is basally perpendicular to the body and whose apical part is curved anteriorly
sutures. 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
