41. Platycoelia altiplana new
species
(Fig. 68)
TYPE SPECIMENS. Male holotype and 11
male paratypes. Holotype male and 7 male
paratypes at ANCB, two male paratypes at
ABTS, and two male paratypes at UNSM labeled
“BOLIVIA, Dept. La Paz Prov. Franz
Tamayo Tojoloque Pastizal 20-22.X.1999 J.
Corro.” Type locality: Totoloque, Franz
Tamayo, La Paz, Bolivia.
HOLOTYPE. Male: length 17.5 mm, width
10.0 mm. Color of dorsal surface light green
to yellow; elytral suture with thick, yellow
margin; elytral disc with 2 weakly raised, yellow,
longitudinal lines. Ventral surface yellow
to yellowish-green. Body ovate, convex. Head:
Dorsal surface glabrous. Frons moderately
punctate, clypeus rugopunctate, punctures
moderate. Frons not depressed. Frontoclypeal
suture complete. Clypeal apex broadly
rounded. Eyes separated by approximately
6.3 transverse eye-widths. Labrum densely
punctate, with moderately large, setose punctures,
setae tawny. Apex of labrum with acute,
triangular, medial tooth, apex of tooth weakly
overlapping apex of mentum. Apex of mentum
with medial notch. Antenna 10-segmented;
club slightly longer than segments 2-7, approximately
equal to length of clypeus.
Pronotum: Surface glabrous, densely punctate,
with small and moderate punctures.
Marginal bead weak laterally, absent elsewhere.
Elytron: Surface glabrous; longitudinal
striae weakly impressed, weakly
punctate; intervals sparsely punctate, punctures
moderate. Suture angled apically without
spine. Pygidium: Width approximately 2.0
times length medially. Surface weakly convex,
sparsely punctate; punctures moderate, setose
(near apical margin); setae short, cream
colored. Venter: Thorax moderately setose (except
glabrous medially), setae white. Mesothoracic
process moderately produced,
projecting anteriorly past mesocoxa, shape cylindrical,
apex rounded, ventrally flattened.
Abdomen sparsely setose, setae white. Apical
2 spiracles extruding, cylindrical. Legs:
Protibia with 3 teeth; 2 subequal in size teeth
in apical quarter, third tooth obsolete.
Mesotibia and metatibia widest medially.
Protarsomeres 2-4 wider than long, cupshaped.
Protarsomere 4 with internoapical
stridulatory ridge. Protarsomere 5 with
internomedial stridulatory tooth. Mesotarsomere
and metatarsomere 5 without internal
tooth or swelling. Unguitractor plate cylindrical,
with 1 apical and 1 subapical seta. Modified
protarsal claw with length greater than
protarsomere 5, thickened and elongate when
compared with other claw, laterally flattened,
apex unevenly bifurcate. Modified mesotarsal
and metatarsal claws elongated with ventral
tooth, not thickened.
VARIATION. Male (n=11). Length 15.5-17.8
mm, width 8.9-10.0 mm. The paratypes to not
differ significantly from the holotype. Other
characters as follows. Head: Mandibular
scissorial region with 2 teeth, molar region
with strong lamellae. Maxilla with 3 apical
teeth, medial tooth bifurcate. Male Genitalia:
Phallobase approximately 1.1 times longer
than length of parameres. Parameres with
apex rounded. Female unknown.
ETYMOLOGY. Platycoelia altiplana means
“the Platycoelia of the Altiplano” referring to
the habitat and region where it occurs.
DIAGNOSIS. This species is distinguished
from all other species in the genus Platycoelia
by the following combination of characters:
frontoclypeal suture complete; apex of the labrum
with a broad, triangular tooth weakly
overlapping the mentum; mentum with a medial
notch; antenna 10-segmented; elytron
with distinct, yellow, longitudinal lines on
striae 3 and 5; elytral apices not capable of
completely covering the pygidium; elytral suture
yellow, apex without an acute spine;
metasternum and abdominal sternites green
to yellow; mesothoracic process projecting
apically past the mesocoxa; apical abdominal
spiracle strongly protuberant; mesotarsomere
5 and metatarsomere 5 without an internal
tooth; parameres with the apex rounded, not
expanded.
