Hypocryphalus

Type species

Hypocryphalus rotundus Hopkins

Adapted from Wood 1982, p. 871-872

Diagnosis

Hypocryphalus can be distinguished from Cryphalus Erichson by the 5-segmented antennal funiclefunicle:
the antennal segments located between the scape and the club in some Coleoptera
, the 3 procurvedprocurved:
pertaining to structure (antennae, setae) which is basally perpendicular to the body and whose apical part is curved anteriorly
to nearly bisinuatebisinuate:
displaying two sinuations
sutures of its sub circular clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
, and by the equally wide tarsomeres.

Description

The length of the only and introduced species in the USA ranges from 1.6 to 1.9 mm, and it is approximately 2.2 times as long as wide. The color is light brown. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is wider than long with the lateral margins marked by a raised line; the anterior half is asperateasperate:
of a surface or texture which is rough
and armedarmed:
having a sclerotized surface structure, giving a rough texture; may serve as defense
in its margin. The declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
is convex with light colored, short, recumbentrecumbent:
applied to setae which lay in the surface of the body
hair-like vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
, with sparsesparse:
scattered, spread irregularly and some distance apart
and erect strial bristles, and is unarmedunarmed:
having no granules, teeth, tubercles, spines, or other protective structures
. 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 longer than its 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 sub-circular, with three procurvedprocurved:
pertaining to structure (antennae, setae) which is basally perpendicular to the body and whose apical part is curved anteriorly
to nearly bisinuatebisinuate:
displaying two sinuations
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
.
