Adapted from Atkinson 2009 and Wood 2007, p. 277-286
Distinguished by the inflated or swollen protibia in the females.
Species in this genus recently documented in the U.S. range in length from 1.8 to 5.7 mm and from 2.1 to 3.1 times as long as wide; the native species is 2.7 mm long and 2.7 times as long as wide. Males are dwarfed and flightless. The color ranges from light reddish brown to almost black. The pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
is usually longer than wide, but ranges to equal or wider than long. Anterior half of the pronotumpronotum:
the upper or dorsal surface of the first thoracic segment
has confused asperitiesasperities:
pertaining to surface roughenings or dot-like elevations that are not pointed
and a series of teeth are present on the anterior margin, the central pair being the largest. 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 usually convex and has granulesgranules:
a small grain-like elevation
or pointed tuberclestubercles:
stiff, pointed, tapered processes on the surface of the integument, usually shorter than a spine
. The scapescape:
the first and basal segment of the insect's antennae
is usually longer than the 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 obliquely truncateobliquely truncate:
pertaining to a structure abruptly and concavely cut
, with two recurvedrecurved:
bent backward or downward as a smiley face
sutures on the anterior face. They have a depresseddepressed:
a structure that is flattened or impressed
pregular region. The anterior coxaecoxae:
the basal or proximal segment of the insect leg to its body
are contiguouscontiguous:
sharing an edge or boundary; touching
. The vestiturevestiture:
a surface covering of scales or setae on the body, wing, or other appendage
consists of erect, hair-like setaehair-like setae:
setae that are thin and similar to a hair
, more abundant posteriorly and on declivitydeclivity:
the apical portion of the beetle elytra that slopes downward
.
Tropical and subtropicalsubtropical:
descriptive of distribution or occurrence above or below the tropics
America from Mexico to Brazil and Ecuador, the Caribbean, and recently found in Florida. Introduced to areas in tropical Africa.
