description: Peltonotus cybele Jameson and Wada, n. sp.   (Fig. 2, 9, 19, 25)  
 Type Material. Holotype female housed at WADA with following label data and maxilla card-mounted beneath specimen: a) “Padang, W. Sumatra, INDONESIA, Jun. 1 1989 ” (handwritten, black ink), b) “24” (handwritten on light green label), c) “new?” (handwritten, black ink), d) our holotype label.   
 Description. Holotype female. Length 14.5 mm. Widest width 7.2 mm. Color (Fig. 2): Head, pronotum, scutellum, propygidium, pygidium, and venter castaneous; elytra castaneous, suffused with dark red and with iridescent bloom. Head: Surface of frons impunctate (base to mid-disc) to moderately densely punctate (mid-disc to apex); punctures simple, some unisetigerous; setae minute. Surface of clypeus moderately densely punctate (base to mid-disc) to densely, confluently punctate (mid-disc to apex); punctures simple, some unisetigerous; setae minute. Clypeus laterally weakly bowed, apex truncate, corners square, beaded; bead weakly arcuate posteriorly. Labrum broadly emarginate at middle. Mandible weakly, obliquely quadrate, apex truncate, inner apex lacking teeth. Mentum with apical half rounded, notched at middle; palpomere 2 not obviously flattened dorsoventrally, 1.5 times width of palpomere 1, sparsely setose; setae moderately long, rufous, not curled at apex, not flattened. Maxilla (Fig. 9): Mala lacking lamellate setal brush; stipes with setae sparse, long, not flattened, not curled at apex; palpomere 2 with weak internomedial bump. Antennal club subequal in length to segments 2-7. Pronotum: Bead lacking anterior to scutellum; anterior bead incomplete at middle. Surface moderately densely punctate, punctures simple, lacking setae laterally. Elytron: Sutural length about 4.0 times length of scutellum. Surface with 5 poorly developed, punctate, longitudinal striae between suture and humerus; punctures moderate in size, moderately dense, lacking setae. Intervals with similar sculpturing. Epipleuron (Fig. 19) in ventral view expanded, deeply incised at base of sternite 2; in dorsal view, expansion well-developed. Propygidium: Surface shagreened and moderately densely punctate (base to mid-disc) to moderately densely punctate (mid-disc to apex); punctures simple, unisetigerous or lacking setae; setae minute (0-1 per puncture), tawny. Pygidium: Surface moderately densely punctate; punctures ocellate, moderately large and large, some unisetigerous; setae minute. Venter: Prosternal keel elongate; apex projecting anteriorly at about 90 o with respect to ventral plane; apex extends to about mid-height of protrochanter, quadrate. Legs: Anterior claws 1/2 length of protarsomere 5, angled toward venter. Meso- and metatibial claws weakly angled toward venter, about 3/4 length of metatarsomere 5.   
 Diagnosis. Peltonotus cybele is similar to P. similis Arrow and P. adelphosimilis Jameson and Wada with which it shares similarities in the form of the maxilla (malar region without lamellate setae, stipes with simple setae [Fig. 9]), labial palpomere 2 (not dorsoventrally flattened and greatly enlarged), and form of the epipleural incision (Fig. 19). It is separated from P. adelphosimilis and P. similis based on the head that has unisetigerous punctures (multisetigerous in P. adelphosimilis and P. similis).   
 This species is unique because the epipleuron is deeply incised at the base of sternite 2 (in ventral view) (Fig. 19). The epipleuron is similarly incised in P. similis and P. malayensis (Fig. 20), but in these species the incision is located adjacent to sternite 3.   
 Etymology. The species epithet refers to Cybele, the Roman goddess of nature.   
 Distribution (Fig. 25). Sumatra, Indonesia.
