NO DATA (2).
One specimen labeled “Guirocoba,
Sonora, MEX” was considered to have no
data. This locality is far out of the known
range of the genus Platycoelia.
TEMPORAL DATA. January (3), February
(40), March (1), May (1), August (1), September
(1), October (9), November (11).
48. Platycoelia furva new species
(Fig. 72)
TYPE SPECIMENS. Male holotype, female
allotype and 2 male paratypes. Holotype male
and allotype female at QCAZ and one male
paratype at ABTS labeled “ECUADOR XII-86
BOLÍVAR TOTORAS Legit L. COLOMA.”
One male paratype at UNSM labeled “ECUA-
DOR XI/86 BOLÍVAR TOTORAS Legit L.
COLOMA.” Type locality: Cashca Totoras,
Azuay, Ecuador.
HOLOTYPE. Male: length 21.8 mm, width
11.9 mm. Color of dorsal surface yellowishgreen;
dark brown maculations on frons,
pronotum, and covering most of elytron (especially
apically, laterally). Ventral surface
black. Body ovate, convex. Head: Dorsal surface
glabrous. Frons rugopunctate, clypeus
rugose. Frons not depressed. Frontoclypeal
suture complete. Clypeal apex broadly
rounded. Eyes separated by approximately
2.9 transverse eye-widths. Labrum densely
punctate, with moderately large, setose punctures,
setae reddish-brown. Apex of labrum
with triangular, medial tooth, apex of tooth
well separated from apex of mentum. Apex of
mentum with medial notch. Antenna 10-segmented;
club approximately equal to segments
2-7, slightly longer than clypeus.
Pronotum: Surface glabrous, densely punctate,
with small and moderate punctures.
Marginal bead weak laterally, absent apically
and basally. Elytron: Surface glabrous; longitudinal
striae weakly impressed, punctate,
punctures moderate. Sutural apex angled,
without spine. Pygidium: Width approximately
1.7 times length medially. Surface con-
vex; disc with base impunctate, apex sparsely
punctate, punctures moderate, setose (near
apex); setae long, reddish-brown. Venter: Thorax
densely setose, setae reddish-brown. Mesothoracic
process weakly projecting
anteriorly past mesocoxa; shape conical, apex
rounded. Abdomen sparsely setose, setae reddish-brown.
Apical spiracles not extruding.
Legs: Protibia with 3 teeth in apical half; apical
2 teeth subequal in size, third tooth obsolete.
Mesotibia and metatibia widest apically.
Protarsomeres 2-4 wider than long, cupshaped.
Protarsomere 4 with weak, apical
stridulatory ridge. Protarsomere 5 with internal
stridulatory surface. Mesotarsomere and
metatarsomere 5 without internal swelling.
Unguitractor plate cylindrical, with 2 apical
setae. Modified protarsal claw with length
approximately equal to protarsomere 5,
greatly thickened and elongate when compared
with other claw, dorsoventrally flattened,
apex unevenly bifurcate. Modified
mesotarsal and metatarsal claw elongate,
with weak ventral tooth, not thickened. Male
Genitalia: Phallobase approximately 1.4
times longer than length of parameres.
Paramere with apex rounded.
ALLOTYPE. Female: length 25.7 mm, width
15.0 mm. As holotype except in the following
respects. Color of elytron almost entirely dark
brown. Legs: Protibia with 3 distinct teeth in
apical half. Protarsomeres unknown (missing
from this specimen).
VARIATION. Male (n=2). Length 23.3-23.5
mm, width 12.9-13.4 mm. Female: known
only from allotype. The paratypes to not differ
significantly from the holotype.
ETYMOLOGY. Platycoelia furva means “the
dark-colored Platycoelia” referring to the appearance
of this species.
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
color mainly dark brown to black; frontoclypeal
suture complete; apex of the labrum with
a reduced, triangular tooth not overlapping
