Description.
Holotype
female. Length
21.3 mm
. Widest width 10.0 mm. Color: Head, pronotum, scutellum, propygidium, pygidium, elytral suture and apical margin castaneous; elytral disc brown with iridescent bloom. Head: Surface of frons with base sparsely punctate, disc moderately densely punctate; punctures simple, lacking setae or multisetigerous laterally; setae minute (1–5 per puncture) or moderately long (0–1 per puncture). Surface of clypeus densely confluently punctate; punctures simple, multisetigerous laterally; setae minute (1–5 per puncture) or short laterally (0–1 per puncture). Clypeus laterally weakly bowed, apex truncate, corners square, beaded; bead weakly arcuate posteriorly. Labrum broadly emarginate at middle. Mandible obliquely quadrate, apex truncate, inner apex with 2 teeth.
Mentum
with apical half rounded (
Fig. 21
), notched at middle; palpomere 2 simple (not dorsoventrally flattened or expanded; lacking abundant, thickened or curled setae), subequal in width to palpomere 1. Maxilla: mala without lamellate setal brush; stipes without dense, long setae (setae simple, not flattened or curled at apex); palpomere 2 lacking internomedial bump. Antennal club slightly longer than segments 2–7. Pronotum: Bead lacking anterior to scutellum. Surface moderately densely punctate; punctures simple, lacking setae. Lateral margin lacking long setae. Elytral sutural length: About 3.3 times length of scutellum. Elytra: Surface with 5 poorly developed, punctate, longitudinal striae between suture and humerus; punctures ocellate, moderate in size, moderately dense, lacking setae. Intervals similarly sculptured. Epipleuron in ventral view not expanded, not deeply incised at apex; in dorsal view lacking expansion (
Fig. 54
). Propygidium: Surface shagreened and moderately densely punctate (disc) to densely confluently punctate (laterally); punctures simple, lacking setae or unisetigerous at apex; setae short (0–1 per puncture), tawny. Pygidium: Surface densely punctate; punctures shallow, simple, unisetigerous or lacking setae; setae minute. Venter: Prosternal keel elongate; apex projecting anteriorly at about 90° with respect to ventral plane, produced to about 1/2 of protrochanter, truncate. Legs: Foreclaws 1/2 length of foretarsomere 5, claws angled toward venter. Meso and metatibial claws with 2 setae, claws angled toward the venter, about 1/2 length of metatarsomere 5.
Paratype
(
1 female
). Differs from the female
holotype
in the following respects. Length 21.0 mm. Widest width
10.1 mm
. Color: Elytral dark brown. Head: Punctures lacking setae. Pygidium: Punctures lacking setae.
Diagnosis. Only female specimens are known for the species. This species is easily recognizable due to its large size (over
20 mm
), brown elytra, and simple epipleuron (
Fig. 54
).
Peltonotus kyojinus
is separated from its congeners by the following characteristics: labrum broadly emarginate at middle; mandible obliquely quadrate, apex truncate; mentum with apical half rounded, palpomere 2 simple (not dorsoventrally flattened or expanded; lacking abundant, thickened or curled setae), subequal in width to palpomere 1; maxilla without lamellate setal brush; stipes without dense, long setae (setae simple, not flattened or curled at apex); maxillary palpomere 2 lacking internomedial bump.
Etymology. The specific epithet “
kyojinus
” is taken from the Japanese word “kyojin” which means “giant”, referring to the large size of this species.
