Diagnosis

The genus Stenoclyptus can be distinguished from the similar genus Pseudothysanoes Blackman by the bisulcatebisulcate:
a structure that is grooved in two places, often contiguous at both sides of a central line
, almost flat and vertical declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
.

Description

Species in this genus range from 1.0 to 1.5 mm in length and are approximately 2.5 times as long as wide. Their color ranges from brown to black. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is wider than long and asperateasperate:
of a surface or texture which is rough
on its anterior half. The anterior margin of the compound eye is sinuatesinuate:
descriptive of a narrow and winding thin structure or margin of a feature
. 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 almost vertical and bisulcatebisulcate:
a structure that is grooved in two places, often contiguous at both sides of a central line
, with light colored setaesetae:
a hollow, often slender and hair-like cuticular projection
, and is unarmedunarmed:
having no granules, teeth, tubercles, spines, or other protective structures
. The scapescape:
the first and basal segment of the insect's antennae
is shorter than the 6-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 oval clubclub:
the apical segment of the insect antennae that is enlarged or thickened such that it is anatomically differentiated from the preceding segments
is small and has two straight 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 separated.
