No. 028­b?" (typeface and handwritten, yellow label), c) our holotype label. Paratype female at FUJI with following label data and mouthparts mounted beneath specimen: a) " Mt. Goram 900 m 15 km SW Kapit SARAWAK N. BORNEO MAY 1998. Tay Poo Min­leg." (typeface), b) " Fujioka­Collection Peltonotus­S­ 1" (typeface and handwritten, yellow label), c) our paratype label.
Description. Holotype female. Length 16.9 mm. Widest width 8.5 mm. Color: Head, pronotum, scutellum, propygidium, pygidium, and venter black; elytra black with iridescent bloom. Head: Surface of frons with base sparsely punctate, disc moderately to densely punctate; punctures simple, lacking setae or multisetigerous; setae minute (1–7 per puncture). Surface of clypeus densely punctate; punctures simple, multisetigerous laterally; setae minute (1–7 per puncture) some short laterally (0–1 per puncture). Clypeus laterally weakly bowed, apex truncate, corners square, beaded; bead not weakly arcuate posteriorly. Labrum broadly narrowly emarginate at middle. Mandible with external edge rounded, inner apex with 2 teeth. Mentum with apical half rounded (e.g., Fig. 20), notched at middle; palpomere 2 dorsoventrally flattened, about 2.5 times width of palpomere 1, setose; setae dense, moderately long, rufous, weakly thickened, weakly curled at apex. Maxilla: mala with dense lamellate setal brush; stipes with setae dense, long, flattened at apex, weakly curled at apex; palpomere 2 with internomedial bump. Antennal club subequal to 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 3.6 times length of scutellum. Elytra: Surface with 5 poorly developed, punctate, longitudinal striae between suture and humerus; punctures ocellate, moderate in size, moderately dense, multisetigerous apically; setae minute (1–7 per puncture). Intervals similarly sculptured. Epipleuron in ventral view expanded, deeply incised at sternite 4; in dorsal view expansion greatly developed (Fig. 63). Propygidium: Surface shagreened and moderately densely punctate (disc) to densely confluently punctate (laterally); punctures simple, unisetigerous or lacking setae; setae minute (0–1 per puncture), tawny. Pygidium: Surface densely punctate; punctures ocellate, multisetigerous or unisetigerous; setae minute (0–5 per puncture). Venter: Prosternal keel elongate; apex projecting anteriorly at about 90° with respect to ventral plane, produced to about 1/2 of protrochanter, rounded. Legs: Foreclaws 1/2 length of foretarsomere 5, claw angled toward venter. Meso– and metatibial claws weakly angled toward venter, about 3/4 length of metatarsomere 5.
Paratype (1 female). Differs from the female holotype in the following respects. Length 18.0 mm. Widest width 8.9 mm. Head: Mandible with external edge rounded, inner apex worn (2 teeth not apparent). Elytra: Punctures lacking setae at apex.
Diagnosis. This species is known only from female specimens but is separated from its congeners by the following characteristics: labrum broadly narrowly emarginate; mandible with external edge rounded; mentum (e.g., Fig. 20) with apical half rounded, palpomere 2 dorsoventrally flattened, about 2.5 times width of palpomere 1, with weakly curled setae; maxilla with dense lamellate setal brush; stipes with setae dense, long, flattened at apex, weakly curled at apex; maxillary palpomere 2 with internomedial bump; epipleuron in ventral view expanded, deeply incised at sternite 4; in dorsal view expansion greatly developed (Fig. 63).
Etymology. The specific epithet “ suehirogarus ” is taken from the Japanese word “suehirogari” which means “fan­shaped” and “to develop or prosper.” The specific epithet has double meaning. It refers to the dense lamellate brush on the maxilla of this species and it also refers to the growing collaboration between Japanese and American researchers that we hope will usher in a prosperous new era of scarab systematics research.
