,
is the Latinized genitive form of the family name of the collector of the

The
palmata
speciesgroup
Diagnostic combination of the
palmata
speciesgroup includes the following: Labrum flat; mentum with lateral lobes acute,
not
spiniform. Head elongate or
not
, broader across middle than occiput, eyes large; head posterior to eyes normally elongate,
not
ballooned (lateral aspect), eyes less than 1.5 times their own diameter from cervical constriction. Tibia moderately or slightly compressed, laterally barely expanded, apex never prolonged; all tibiae lateroapically oblique. Elytral apex bidentate, dentiform projections small.
The
palmata
speciesgroup was revised by Erwin (1984). At that time, it contained 39 species whose composite range extends from southern
México
to
Paraguay
. Since then, 13 new species have been discovered from throughout the overall range, plus another one from
Costa Rica
, described below.
Four other species of the
palmata
speciesgroup are known from

,
