TYPE SPECIMENS. Platycoelia prasina
Erichson lectotype male at ZMHB labeled a)
“11468” (typeface), b) “Type” (orange label,
typeface), c) “Prasina (N.) Er.* Peru. Pavon”
(green label, handwritten), d) “PLATYCOE-
LIA PRASINA ERICHSON M DET: A.B.T.

and typeface). Lectotype here designated.
See Methods and Materials section
for a statement of taxonomic purpose.
Erichson (1847) did not state how many specimens
were in the type series. The existence
and location of paralectotypes are unknown.
Type locality: Perú.

See Methods and Materials section for
a statement of taxonomic purpose. Ohaus
(1904b) did not state how many specimens
were in the type series. The existence and location
of paralectotypes are unknown. Although
P. prasina has some variable traits, I
could find no consistent differences that justify
maintaining P. limbata as a separate species.
Therefore I am synonymizing the two
names. The specimens of P. prasina that I examined
from Perú, Bolivia, and Argentina are
variable within each area and more specimens
will have to be examined to properly
assess this variation. Type locality: Salta,
Argentina. NEW SYNONYMY.
DESCRIPTION. Male (n=15). Length 17.2-
21.2 mm, width 9.6-12.8 mm. Color of dorsal
surface olive green; pronotum, scutellum,
elytron with yellow margins. Ventral surface
yellowish-green to olive green, metasternum
sometimes with dark medial patch. Body
ovate, convex. Head: Dorsal surface glabrous.
Frons densely punctate, clypeus rugopunctate,
punctures moderate. Frons not depressed.
Frontoclypeal suture complete.
Clypeal apex rounded. Eyes separated by approximately
4.3 transverse eye-widths. Labrum
densely punctate, with moderately
large, setose punctures, setae tawny. Apex of
labrum with small, triangular, medial tooth,
apex of tooth weakly overlapping apex of mentum.
Mandibular scissorial region with 2
teeth, molar region with strong lamellae.
Maxilla with 3 cup-shaped teeth. Mentum
apical tooth curved into oral cavity. Antenna
9-segmented; club approximately equal to
other segments combined, slightly longer
than length of frons. Pronotum: Surface glabrous,
moderately punctate, with small and
moderate punctures. Marginal bead weak
laterally, absent elsewhere. Elytron: Surface
glabrous; longitudinal striae impressed, punctate;
punctures moderate with dark coloration;
intervals impunctate. Suture apically angled,
without acute spine (sometimes with weak
nub). Pygidium: Width approximately 1.9
times length medially. Surface weakly convex,
