MONOGRAPHIC REVISION OF PLATYCOELIA 175
ETYMOLOGY. The specific name of P.
aenigma is the Latin word for “a mystery.” I
feel this name is appropriate for such an unusual
species, especially since it is only known
from one old specimen with poor data and no
abdomen.
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
dorsal color light green with light brown
elytron; frons sparsely setose laterally;
frontoclypeal suture complete; apex of the labrum
with a reduced, triangular tooth not
overlapping the mentum; mentum with a medial
notch; antenna 10-segmented; pronotum
with weak maculations; elytron without distinct,
yellow, longitudinal lines; apex of elytral
suture without acute spine; mesothoracic process
nub to weakly projecting apically;
mesotarsomere 5 and metatarsomere 5 without
internal tooth; modified mesotarsal claw
in male with apex bifurcate, dorsoventrally
flattened.
DISTRIBUTION (Fig. 72). Known from Perú
with no precise locality.
LOCALITY DATA. 1 specimen examined
from BMNH.
PERÚ (1). NO DATA (1).
The holotype is labeled “Amaz Nauta”
which is in the lowlands of Perú. I assume
that the actual collecting locality was in the
Andes Mountains somewhere west of Nauta.

and existence of other paralectotypes are

specimens were deposited in the Hamburg
collection. These specimens, along with the
entire Coleoptera and Lepidoptera collections,
were completely destroyed in July 1943 by air
raid bombing (Klapperich 1948). Type locality:
Chulumani, La Paz, Bolivia.

15.0 mm, width 8.6-8.9 mm (Fig. 76). Color

setose, setae tawny. Frons sparsely punctate
