MONOGRAPHIC REVISION OF PLATYCOELIA 171
54. Platycoelia ignota new species
(Fig. 72)
TYPE SPECIMEN. Male holotype. Holotype
male at BMNH labeled “549.,” “67 45,” “Callichloris
Lafertei Reiche Colombia,” and “So
named in Reiches Collection. C. W.” Type locality:
Colombia.
HOLOTYPE. Male: Length 23.3 mm, width
12.9 mm. Color dorsally black with green
clypeus, pronotum, and pygidium, pronotum
with dark brown maculations. Ventrally yellowish-brown
to brown. Body subovate, convex.
Head: Dorsal surface sparsely setose at
clypeal apex; setae tawny. Frons moderately
to densely punctate, clypeus rugose. Frons
weakly depressed. Frontoclypeal suture complete.
Clypeus rectangular with reflexed apex.
Eyes separated by 6.0 transverse eye-widths.
Labrum rugose, setose; setae tawny. Apex of
labrum with triangular, medial tooth, apex of
tooth separated from apex of mentum. Apex
of mentum with medial notch. Antenna 9-segmented;
club slightly shorter than segments
1-6, approximately equal to clypeal length.
Pronotum: Surface glabrous, sparsely punctate,
with moderate punctures. Marginal bead
present laterally, absent apically and basally.
Elytron: Surface glabrous; longitudinal striae
weakly impressed or not impressed, weakly
punctate; punctures moderate; intervals
impunctate. Suture rounded apically, without
spine. Pygidium: Width 1.8 times length medially.
Surface weakly convex, sparsely punctate
near apex; punctures moderate, with
some scattered setae. Venter: Thorax densely
setose, setae tawny. Mesothoracic process reduced,
not projecting anteriorly past mesocoxa.
Abdomen sparsely setose laterally; setae
long, tawny. Apical 2 spiracles not extruding.
Legs: Protibia with 3 teeth in apical half; apical
2 teeth close together, longer; third tooth
shorter. Mesotibia and metatibia widest
apically. Protarsomeres 2-4 wider than long,
cup-shaped. Protarsomere 4 with internoapical
stridulatory ridge. Protarsomere 5 with
internomedial tooth bearing stridulatory
ridge. Mesotarsomere and metatarsomere 5
without internal swelling or tooth. Unguitractor
plate cylindrical, with 1 apical, 1 sub-
apical seta. 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 claws elongated
with ventral tooth, not thickened. Male Genitalia:
Phallobase 1.2 times longer than length
of parameres. Parameres with apex rounded.
ETYMOLOGY. Platycoelia ignota is Latin for
the “unknown” or “obscure” Platycoelia. The
name reflects the fact that this species is known
from only one specimen with poor data.
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
color dorsally black with a green clypeus,
pronotum, and pygidium; frontoclypeal suture
complete; apex of the labrum with a reduced,
triangular tooth not overlapping the mentum;
mentum with a medial notch; antenna 9-segmented;
pronotum with weak maculations;
elytron without distinct, yellow, longitudinal
lines; elytral apices not capable of completely
covering the pygidium; apex of the elytral suture
without an acute spine; mesothoracic
process nub to weakly projecting apically; apical
abdominal spiracle not protuberant;
mesotarsomere 5 and metatarsomere 5 without
an internal tooth; parameres with the
apex rounded, not expanded.
DISTRIBUTION (Fig. 72). Colombia, the
precise locality is unknown.
