E2094C37FFF10D675AB6C397FE8AC997.taxon	diagnosis	Diagnosis. Peltonotus animus (Fig. 1) is distinguished from other Sumatran species of Peltonotus based on the following characters: apex of metatibia in male with longer spur produced to apex of metatarsomere 2 (shared with P. sisyrus; spur shorter in P. cybele, P. talangensis, and P. gracilipodus); mala with setae curled at the apices (Fig. 5) (shared with P. gracilipodus; not curled in P. cybele, P. talangensis, and P. sisyrus); protibia bidentate (Fig. 11) (shared with P. gracilipodus and P. sisyrus; tridentate in P. cybele and P. talangensis); and form of the male genitalia (Fig. 18 a – b). Outside of Sumatra, P. animus shares many character states with P. silvanus Jameson & Wada 2004 from Sarawak and Kalimantan on the island of Borneo (see Jameson and Wada 2009).

E2094C37FFF10D615AB6C011FCB7C8C7.taxon	description	Peltonotus cybele 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. Description of male (n = 2). The male differs from the female holotype in the following respects. Length 16.4 – 16.5 mm. Widest width 8.0 mm. Color (Fig. 2): Head, pronotum, scutellum, propygidium, pygidium, and venter castaneous; elytra dark reddish-brown with iridescent bloom. Head: 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. Elytron: Surface with 5 poorly developed, punctate, longitudinal striae between suture and humerus, lateral-most striae poorly defined. 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, 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 ° with respect to ventral plane; apex extends to about mid-height of protrochanter, quadrate. Legs: 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; Figures Į – 4. Peltonotus species dorsal habitus.

E2094C37FFF10D615AB6C011FCB7C8C7.taxon	diagnosis	Diagnosis. Within Sumatra, P. cybele is distinguished from other species of Peltonotus 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 P. talangensis; bidentate in P. animus, P. gracilipodus, and P. sisyrus); mentum with rounded apex (shared with P. animus and P. gracilipodus; apex triangular in P. talangensis and P. sisyrus); unisetigerous punctures on the head (shared with P. talangensis; punctures clearly multisetigerous in P. animus, P. sisyrus, and P. gracilipodus); form of the male genitalia (Fig. 19 a – b); and female epipleuron incised and with rounded emargination in ventral view (Fig. 14). Outside of Sumatra, P. cybele shares several similarities with P. similis Arrow 1931 and P. adelphosimilis Jameson & Wada 2004 from Sabah on the island of Borneo (Jameson and Wada 2009).

E2094C37FFF10D615AB6C011FCB7C8C7.taxon	discussion	Remarks. Peltonotus cybele 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.	en	Jameson, Mary, Jakl, Stanislav (2010): Synopsis of the aroid scarabs in the genus Peltonotus Burmeister (Scarabaeidae, Dynastinae, Cyclocephalini) from Sumatra and description of a new species.

E2094C37FFF70D625AB6C0E1FD71CF27.taxon	diagnosis	Diagnosis. Within Sumatra, P. gracilipodus is separated from other species of Peltonotus based on the surface of the frons and clypeus that has multisetigerous punctures (shared with P. animus and P. sisyrus; unisetigerous in P. cybele and P. talangensis); form of the mentum that is rounded in the apical half (Fig. 8) (shared with P. animus and P. cybele; triangular in P. sisyrus and P. talangensis); form of the male genitalia (Fig. 20 a – b); and form of the female epipleuron in ventral view (Fig. 15). Outside of Sumatra, P. gracilipodus closely resembles P. podocrassus Jameson & Wada 2004 from peninsular Malaysia. In fact, males of both species have very similar genitalic forms and females have very similar eplipleural forms. Other characters differ between the species (e. g., length of the metatibial spur, slender versus robust form of the fifth protarsomere in the male). Similarity in the genitalic form may provide evidence of recent isolation of ancestral populations in Sumatra and peninsular Malaysia. Locality records (Fig. 23) (n = 13). SUMATRA.

E2094C37FFF50D6F5AB6C397FDB2C997.taxon	diagnosis	Diagnosis. Peltonotus talangensis is distinguished from other Sumatran Peltonotus species based on the form of the mentum that is triangular in the apical half (Fig. 10; shared with P. sisyrus); surface of frons and clypeus unisetigerous (shared with P. cybele; multisetigerous in P. sisyrus, P. gracilipodus and P. animus); the short prosternal keel that extends to about a quarter of the height of the protrochanter (in all other species of Peltonotus, the prosternal keel extends one third to three quarters the height of the protrochanter); and the simple female epipleuron (Fig. 17). Outside of Sumatra, P. talangensis shares the triangular apex of the mentum with P. deltomentum from Kalimantan on the island of Borneo. Locality records (Fig. 23) (n = 118). SUMATRA.

E2094C37FFF50D6F5AB6C397FDB2C997.taxon	discussion	Remarks. Peltonotus talangensis was collected at 1450 m elevation on the southern slopes of Mt. Talang in the Diatas Lake region (February 15 – 16, 2006). This locality is home to a number of endemic species (including a new species of Cetoniinae) and is climatically much cooler (even at 1000 m elevation) than other volcanoes in the region. Specimens were collected at lights for two nights only, after which adult flight activity completely ceased, although collecting in the region was on-going.
