Micracis

Type species

Micracis suturalis LeConte

Adapted from Wood 1982, p. 578-594

Diagnosis

Micracis is similar to Hylocurus Eichhoff and Micracisella Blackman and can be distinguished from them by the aspect of the scapescape:
the first and basal segment of the insect's antennae
which is often flattened into a triangular shape. In addition, it can be distinguished from Micracisella by the entire margin of the compound eye.

Description

Species in this genus range from 1.6 to 3.4 mm in length. Their color ranges from yellowish brown to dark reddish brown. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is longer than wide, and the anterior area is asperateasperate:
of a surface or texture which is rough
. The scutellumscutellum:
a shield-like bony plate or scale, as on the thorax of some insects
is large. The declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
is convex and acuminateacuminate:
tapering gradually to a sharp point
at the apex, with a hair-like vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
. The anterior margin of the compound eye is entire. 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 is triangular; it is also ornamentedornamented:
having markings or structures on the esclerotized regions of the integument, such as setae, tubercles, or granules
by long hair. 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 and has 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 usually widely separated.
