Holotype male at MNHN with label data: a) "Kina­balu N. Borneo" (handwritten), b) " Peltonotus brunnipennis TYPE" (handwritten, orange paper), c) " Peltonotus brunnipennis E. Benderitter , det. Bend TYPE" (handwritten and typeface), d) " Peltonotus brunnipennis Benderitter m Holotype " (our red holotype label). Male genitalia and maxilla card­mounted. Holotype missing both foretarsi. Benderitter (1934) stated that the description was based on a unique specimen, therefore the holotype is fixed by monotypy. Description (males=2, female=1). Length 14.5–16.9 mm . Widest width 7.9–8.5 mm . Color: Male: Head, pronotum, scutellum, propygidium, pygidium, and venter shining, castaneous; elytra reddish­orange or black with iridescent bloom. Female: Head, pronotum, scutellum, propygidium, pygidium, and venter shining castaneous to black; elytra black with iridescent blue bloom. Head: Surface of frons with base impunctate, middle frons to apex densely punctate; punctures ocellate or semi­lunar, not setigerous on disc. Surface of clypeus densely punctate; punctures ocellate or semi­lunar, not setigerous on disc. Clypeus weakly bowed laterally; apex truncate, corners square, beaded; bead at middle weakly arcuate posteriorad. Labrum deeply, narrowly emarginate at middle. Mandibles of male and female rounded laterally, inner apex with 2 weak teeth. Mentum with apical half rounded, notched at middle; palpomere 2 dorsoventrally flattened, twice width of palpomere 1, setose; setae dense, moderately long, rufous, weakly curled at apex, flattened. Maxilla: mala with lamellate setal brush; stipes with setae dense, long, flattened, 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. Lateral margin lacking long setae. Elytral sutural length: About 5.0 times length of scutellum. Elytron: Surface with 5 poorly developed, punctate, longitudinal striae between suture and humerus; punctures moderate in size, moderately dense. Intervals with similar sculpturing. Epipleuron of female in ventral view expanded, incised at apex; in dorsal view expansion moderately developed ( Fig. 51 ). Propygidium: Surface moderately densely punctate; punctures ocellate, not setigerous. Pygidium: Surface moderately densely punctate; punctures ocellate, not setigerous. Venter: Prosternal keel subtriangular; apex produced to middle of protrochanter, rounded. Legs: Foretibia of male tridentate with weak basal tooth; lateral margin lacking short, dense setae. Foretarsomere 5 of male subequal in length to tarsomeres 1–4; foretarsomere 3–4 with apices expanded, ventral apices with small patch of dense, short setae. Foreclaws of male with inner claw curved, about 3 times thicker than outer claw; outer claw simply arcuate, about 3/4 the length of inner claw; empodium bulbous at base. Foreclaws of female 3/4 length of foretarsomere 5, not angled toward venter. Meso­ and metatibial claws of male with 2 setae, claws 3/4 length of tarsomere 5, not angled toward venter. Metatibia of male with apical spurs weakly curved; ventral spur produced to middle of metatarsomere 1, dorsal spur produced to middle of metatarsomere 2. Parameres: Fig. 38a–c . Diagnosis. Peltonotus brunnipennis is separated from other species of Peltonotus based on the following characters: labrum deeply, narrowly emarginate at middle apex, enlarged palpomere 2, lamellate brush on mala, form of male genitalia ( Fig. 38a–c ), claws not strongly angled toward venter and about 3/4 length of metatarsomere 5, lack of setae on the head, male foretibia tridentate, epipleuron of female in ventral view expanded, incised at sternite 3, expansion moderately developed in dorsal view ( Fig. 51 ). Distribution ( Fig. 66 ). Sabah State , Bornean Malaysia . Locality records ( 3 specimens ) from FUJI , MNHN , WADA . BORNEAN MALAYSIA . Sabah State (3): Crocker Range, Mt. Kinabalu, Ranau. Temporal Data. July (2). Remarks. This species is known by only three specimens , two males and one female . Although the male holotype specimen of P. brunnipennis is missing both foretarsi, we were able to assign one male specimen from Crocker Range to P. brunnipennis based on: mouthpart characters, male genitalia, form of the meso­ and metatarsal claws, form of the male foretibia, and lack of setae on the head. These specimens differ slightly in elytral coloration (reddish­brown in the holotype specimen; castaneous in the Crocker Range specimen). The female specimen from Ranau was assigned to this taxon based on mouthpart characters, form of the meso­ and metatarsal claws, and lack of setae on the head. Benderitter (1934) based his description of this species on one male specimen. He described a transverse furrow in the third metatarsomere, and he questioned whether this was diagnostic of the species. Based on our observations, this is simply a developmental abnormality.
