( Figs. 28 , 49a–c , 62 , 65 ) Type Material. Holotype male housed at FUJI with following label data and male genitalia and mouthparts mounted beneath specimen: a) "near Aceh N. SUMATRA 1993. NOV." (type face), b) " Fujioka­Collection Peltonotus­G­1" (typeface and handwritten, yellow label), c) our holotype label . Allotype female housed at FUJI with following label data: a) "near Brastagi NORTH SUMATRA JUN. 1995 ." (type face), b) "Fujioka­Collection Peltonotus­G­2" (typeface and handwritten, yellow label), c) our allotype label . Description. Holotype male. Length 16.1 mm . Widest width 7.7 mm . Color: Head, pronotum, scutellum, pygidium, elytron, and venter castaneous. Elytra with weak iridescent bloom Head: Surface of frons with base impunctate (middle) to sparsely punctate (laterally), middle frons to apex moderately densely punctate, more dense laterally; punctures simple, multisetigerous; setae minute (1–12+ per puncture) and moderately long adjacent to eye (0–1 per puncture). Surface of clypeus moderately densely punctate, more dense laterally; punctures simple, multisetigerous; setae minute (1–12+ per puncture) and short near margin (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 triangular, notched at middle; palpomere 2 dorsoventrally flattened, about 3 times width of palpomere 1, setose; setae dense, moderately long, rufous, weakly thickened, not curled. Maxilla ( Fig. 28 ): mala with dense lamellate setal brush; stipes with setae dense, long, flattened at apex, not curled at apex; palpomere 2 with weak internomedial bump. Antennal club subequal to segments 2–7. Pronotum: Bead lacking anterior to scutellum. Surface moderately densely punctate; punctures simple, multisetigerous laterally; setae minute (1–7 per puncture) and short (0–1 per puncture). Lateral margin lacking long setae. Elytral sutural length: About 3.5 times length of scutellum. Elytra: Surface with 7 poorly developed, punctate, longitudinal striae between suture and humerus; punctures ocellate, moderate in size, moderately dense, multisetigerous apically and laterally; setae minute (1–20+ per puncture). Intervals similarly sculptured. Propygidium: Surface shagreened and moderately densely punctate; punctures simple, unisetigerous (short at base to mid­disc) and multisetigerous (minute at apex). Pygidium: Surface densely punctate; punctures ocellate, multisetigerous; setae minute (7–20+ per puncture) and long at apex (1–2 per puncture). Venter: Prosternal keel elongate; apex projecting anteriorly at about 90° with respect to ventral plane, produced to about 3/4 of protrochanter, truncate. Legs: Foretibia of male bidentate; lateral margin with short, dense setae. Foretarsomere 5 subequal in length to tarsomeres 1–4, greatly thickened; foretarsomeres 2–4 with apices expanded (moreso in 3), dorsal and ventral apices of tarsomeres 1–4 clothed with small patch of dense, short setae. Foreclaws with inner claw broadly curved, about 3 times thicker than outer claw; outer claw elongate­arcuate, about 1/2 the length of inner claw; empodium bulbous at base. Meso­ and metatibial claws of male with 2 setae, claw angled toward venter, about 1/2 length of metatarsomere 5. Metatibia of male with apical spurs more or less straight; ventral spur produced to middle of metatarsomere 1, dorsal spur produced to apex of metatarsomere 2. Parameres: Fig. 49a–c . Allotype Female. Differs from the holotype in the following respects. Length 16.4 mm . Widest width 7.6 mm . Color: Head, pronotum, scutellum, propygidium, pygidium, and venter black; elytra black with iridescent bloom. Head: Surface of frons densely punctate, multisetigerous; setae minute (1–12+ per puncture) and short (0–1 per puncture). Surface of clypeus densely punctate, multisetigerous; setae minute (1–12+ per puncture) and short (0–1 per puncture). Pronotum: Punctures unisetigerous apicolaterally; short (0– 1 per puncture). Propygidium: Punctures unisetigerous with line of short setae near apex. Elytron: Epipleuron of female in ventral view expanded, broadly incised at sternite 4; in dorsal view expansion moderately developed ( Fig. 62 ). Legs: Foreclaws subequal 1/2 length of foretarsomere 5, claw angled toward venter. Diagnosis. Peltonotus sisyrus is one of only two Peltonotus species that possess a mentum that is triangular in the apical half ( Fig. 28 ; shared with P. deltamentum ). It is easily separated from other species of Peltonotus based on the greatly enlarged fifth foretarsomere in the male and its distribution in northern Sumatra . In addition, the surface of frons and clypeus is multisetigerous; labrum broadly narrowly emarginate at middle; mandible with external edge rounded; male with foretarsomere 5 greatly thickened and apices of tarsomeres 1–4 clothed with small patches of dense, short setae; outer foreclaw elongate­arcuate; and epipleuron of female in ventral view expanded, broadly incised at sternite 4 ( Fig. 62 ). Etymology. The specific epithet “ sisyrus ” is Greek for “shaggy garment” and refers to the dense short and long setae on the head of this species. Distribution ( Fig. 65 ). Sumatra , Indonesia .
