description: <i>Peltonotus cybele</i> Jameson &amp; Wada, 2009 Figs 2–3, 6, 12, 14, 19a–b, 23 <i>Peltonotus cybele</i> was previously known only by the female holotype specimen (Fig. 3). Discovery of the first male specimens (e.g., Fig. 2) and a second female facilitates identification of the species. <b>Description of male (n=2).</b> The male differs from the female holotype in the following respects. Length 16.4–16.5 mm. Widest width 8.0 mm. <i>Color</i> (Fig. 2): Head, pronotum, scutellum, propygidium, pygidium, and venter castaneous; elytra dark reddish-brown with iridescent bloom. <i>Head:</i> Maxilla (Fig. 6) as in holotype, mala lacking lamellate setal brush; stipes with setae sparse, long, not flattened, not curled at apex; palpomere 2 with weak internomedial bump. <i>Elytron:</i> Surface with 5 poorly developed, punctate, longitudinal striae between suture and humerus, lateral-most striae poorly defined. <i>Propygidium:</i> 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, tawny. <i>Pygidium:</i> Surface moderately densely punctate; punctures ocellate, moderately large and large, some unisetigerous; setae minute. <i>Venter:</i> Prosternal keel elongate; apex projecting anteriorly at about 90° with respect to ventral plane; apex extends to about mid-height of protrochanter, quadrate. <i>Legs:</i> Protibia (Fig. 12) of male tridentate; lateral margin with short, dense setae. Protarsomere 5 of male subequal in length to tarsomeres 1–4; protarsomere 3–4 with apices expanded, dorsal and ventral apices clothed with dense, short setae. Anterior claws of male with inner claw curved, about 4 times thicker than outer claw; outer claw simply arcuate, about half length of inner claw; empodium bulbous at base. Meso- and metatibial claws with 2 setae. Metatibia with apical spurs weakly curved; 3 <i>Peltonotus cybele</i>, female 4 <i>Peltonotus talangensis</i>, holotype male <b>Figures &amp;Iogon;–4.</b> <i>Peltonotus</i> species dorsal habitus. <b>&amp;Iogon;</b> <i>P. animus</i> (holotype, male) <b>2</b> <i>P.</i> cybele, male <b>3</b> <i>P.</i> cybele (holotype, female) <b>4</b> <i>P.</i> talangensis (holotype, male). ventral spur produced to middle of metatarsomere 1, dorsal spur produced to apex of metatarsomere 2. <i>Parameres</i>: Figs 19a–b. <b>Diagnosis.</b> Within Sumatra, <i>P. cybele</i> is distinguished from other species of <i>Peltonotus</i> based on the dark reddish-brown elytral coloration in the male (elytra castaneous and suffused with reddish brown in the female). Additional characters that enable identification include: protibia of the male tridentate (Fig. 12) (shared with <i>P. talangensis</i>; bidentate in <i>P. animus</i>, <i>P. gracilipodus</i>, and <i>P. sisyrus</i>); mentum with rounded apex (shared with <i>P. animus</i> and <i>P. gracilipodus</i>; apex triangular in <i>P. talangensis</i> and <i>P. sisyrus</i>); unisetigerous punctures on the head (shared with <i>P. talangensis</i>; punctures clearly multisetigerous in <i>P. animus, P. sisyrus,</i> and <i>P. gracilipodus</i>); form of the male genitalia (Fig. 19a–b); and female epipleuron incised and with rounded emargination in ventral view (Fig. 14). Outside of Sumatra, <i>P. cybele</i> shares several similarities with <i>P. similis</i> Arrow 1931 and <i>P. adelphosimilis</i> Jameson &amp; Wada 2004 from Sabah on the island of Borneo (Jameson and Wada 2009). <b>Locality records</b> (Fig. 23) (n=4). SUMATRA. <i>West Sumatera Province</i> (4): Padang, Mt. Sanngul (20–30 km N. Payakumbuh, 1000–1300m). <b>Temporal data.</b> June (1), April (2), October (1). <b>Remarks.</b> <i>Peltonotus cybele</i> was previously known only from the holotype female (housed in WADA). We record the first known male specimens and an additional female specimen (housed in MLJC and SJC). The second known female greatly resembles the female holotype in size, coloration, and other respects.
