039B87833E74FFEC9FD209431E0192E2.taxon	distribution	Distribution. Romblon Province, Philippines. Comparative notes. This new species shares several external characteristics with C. zeylanicum and C. aemulator, described from Sri Lanka and Sumatra respectively. It differs from the both, firstly regarding the structure of prothorax. It is more voluminous, broader in relation to body, more convex in profile (Figs 1 B, 2), and more arcuate on sides. Secondly, punctures on elytra are larger and deeper near base and humeri. Thirdly, antennal supports are more flattened. In addition, its pronotum is much more deeply and coarsely punctured than that of C. zeylanicum. As for genital organs, 8 th sternite of the new species is more strongly emarginated on apex than that of C. zeylanicum (Figs 14 I, 25 F) and, according to the description, less so than that of C. aemulator. Further, the 8 th tergite is apicad much more strongly narrowed than that of the former and not truncated as of the latter (Figs 14 K, 25 G). Regarding median lobe, it is bullet-shaped in dorsal view in contrast to the fusiform one of C. zeylanicum. It is also less arcuate in profile (Figs 14 A- B, 25 A- B).	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

039B87833E75FFEB9FF00A5E1D599366.taxon	distribution	Distribution. Northern Luzon, Philippines. Comparative notes. With short, stout body and long, stout antennae, this new species differs from all the other species of the genus Ceresium. In this regard, it resembles rather more those species of the neighbouring genus Examnes Pascoe, 1869, in particular, the nominotypical E. philippensis Newman, 1842. Its frons is, however, neither short nor steep, and its antennal supports are very flat without any tubercle, both in contrast to the definition of Examnes (Pascoe 1869). The new species must be thus placed in the genus Ceresium, at least for the moment.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

039B87833E72FFEB9FEC0ADA1CF09682.taxon	distribution	Distribution. Sibuyan Is., Romblon Province, Philippines. Comparative notes. This new species resembles C. zeylanicum regarding the body structure in general. Pronotum of the latter is, however, obviously less regularly punctured and much more setose. The puncture on pronotum of the new species resembles rather that of C. mediocre, whose pronotum is, in turn, shorter and more setose. Further, it can be compared to C. lingafelteri Vives, 2013 from the nearby island Luzon. It lacks, however, the remarkable band on elytra, and its pronotum differs in outline and integument. As for male genital organs of the new species, median lobe is distinctly wider and the 8 th sternite much more deeply emarginated on apex than those of the other species examined.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

039B87833E71FFE79C040AD61CB4914C.taxon	distribution	Distribution. Sibuyan Island, Romblon Prov. Philippines. Comparative notes. This new species can be compared to C. detanii Yokoi, 2015 and C. gracile (Perroud, 1855), from Bali and Sri Lanka respectively. Both of them are almost entirely yellowish in colour and provided with elongated cylindrical prothorax, whereas the prothorax of the former is shorter and that of the latter longer than of the new species. Puncture and setae on pronotum are meanwhile obviously different. The new species lacks also the remarkable maculation of C. gracile, instead provided with conspicuous black colouration on legs. As to genital organs, median lobe of C. detanii is distinctly slenderer and tegmen more strongly arcuate in profile. It can be also compared to C. angustulum Gahan, 1906 from South India. Prothorax of the new species, is, however, clearly more strongly elongated. Both species differ also in colouration of body, eyes and legs. In addition, elytra of the new species are clothed properly with setae, though short, like the other Ceresium species, in contrast to the more obtusely setose elytra of C. angustulum. The new species shares the similar remarkable colouration of legs with C. helleri Gressitt, 1940 from the nearby Luzon. Pronotum of the latter is, however, sub-conic (Fig. 13 B) instead of cylindrical. Further, its elytra are clothed only with minute hairs and instead furnished with sporadic, long, flying hairs on pronotum, which the new species lack. In addition, venter of C. helleri is extensively naked and shiny (Fig. 13 A), and its femora are more suddenly clavate with longer peduncle (Fig. 13 A). It should be added, that the new species bears certain resemblance to species of the neighbouring genus Stenodryas, on account of elongated and rather obtusely punctured pronotum. In particular, Stenodryas filipinus (Vives, 2009) shares even the remarkable colouration of legs with the new species and with C. helleri. Other important characteristics such as body structure, length of antennae, structure of legs, integument on elytra and body indicate, however, that the new species should be indeed integrated in the genus Ceresium (see Discussion).	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

Pronotum of this new species is peculiar, differing from those of all the other known species of the genus Ceresium. C. breoipes or C. grandicolle Holzschuh, 2015 shares an analogously large pronotum, though not quite reaching the volume of the new species. Structure, setae and colour of pronotal surface are, however, obviously different. C. striaticolle Holzschuh, 2011 has also a rather large pronotum with striate surface and macula. The pronotum is, however, different in outline. As to genital organs of the new species, not only 8 th sternite, ejaculatory duct or spicum gastrale, but also the outline and surface of tegmen is rather singular in the genus.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

Further, punctures on pronotum are shallower and hairs on elytra shorter. C. femoratum and C. flaoicorne differ additionally regarding the colour of legs or antennae, while C. raripilum and C. rouyeri differ with the presence of erect hairs on pronotum and legs. Longer antennae and moderately raised antennal supports are suggestive of the closely related genus Examnes (Pascoe 1869). Its frons is, however, neither short nor steep. In addition, the new species is slenderer than C. philippensis, the nominotype of Examnes, and other members of the genus.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

039B87833E67FFFE9FE50B131B1990B8.taxon	distribution	Distribution. North Sumatra, Indonesia. Comparative notes. This new species from Sumatra resembles C. mediocre from Borneo in many aspects, above all regarding the structure of head, body and legs. It can be distinguished, however, by its homogenous colouration as well as by the distinctly less setose pronotum. In addition, its 8 th sternite is emarginated in semi-circular form on apex, differing from the sternite of C. mediocre, which is emarginated in shallow U-form with acute latero-basal edges.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

Legs paler in colour. Elytra and antennae yellowish brown. Eyes darker. Head. Similar to that of C. detanii in outline; lustreless; similarly clothed with hairs; more shallowly punctured. Vertex with deeper elliptical punctures. Eyes and antennae similar. Pronotum. Similarly cylindrical as in C. sibuyanum sp. nov.; a little longer than in C. detanii. Sides feebly emarginated in double-sinuate line; constricted near apex. Disc uneven; surface lustreless; sparsely provided with large though very shallow and obtuse punctures; shallowly scabrous-rugose in part; hairs on disc somewhat resembling those of C. subfuloum Holzschuh, 2015; though the hairless area in the middle more extensive and the apical and dorsal pairs of hairless elevations much larger. Scutellum triangular; pale yellowish pubescent. Elytra. A little shorter than those of C. detanii, longer than of C. subfuloum. Legs. Similar as in C. detanii. Venter. Similar. Prosternum obtusely punctured. Mesosternum extensively nitid. Abdomen. Similar, 5 th visible sternite with apex broadly rounded. Female genital organs as in Figure 23 A- D. 8 th sternite and 8 th tergite both squarish in outline. 8 th tergite provided with several long and stout setae on apex. 9 th abdominal sternite moderately long; coxite a little longer than paraproct; coxital lobe well sclerotized; furnished with several hairs of medium length. Spermatheca composed of thick shagreened membrane; shaped like a comma mark. Spermathecal duct extremely expanded at the base of spermatheca to form a spherical enlargement, which is longer than and three times as wide as spermatheca itself; surface thick, leathery, shagreened and wrinkled.

039B87833E67FFF89DF609B01D7B964B.taxon	distribution	Distribution. N. Sumatra, Indonesia. Comparative notes. Of the flavo-fulvum coloured species of Ceresium, solely C. detanii, C. gracile and C. sibuyanum sp. nov. have a cylindrical prothorax like this new species. However, they differ distinctly regarding puncture, hairs and maculation on pronotal disc. It is also comparable, to a lesser degree though, to C. subfuloum from Borneo, sharing the fundamental colouration pattern in common. Pronotum of the latter is, however, shorter, less cylindrical, more extensively punctate and setose. The extremely large spherical expansion of spermathecal duct at the base of spermatheca, as found in the holotype, is remarkable.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.

039B87833E61FFF89FCD0FE71B589474.taxon	distribution	Distribution. Borneo; Malay Peninsula; Sumatra (new record). Comparative notes. The examined specimen lacks those sparse, long, standing hairs of holotype on the underside and elytra, and its 8 th tergite is trapezoidal in outline instead of rectangular. Otherwise, it well corresponds to the holotype regarding habitus and genital organs. Similarities in important characteristics outweigh by far those few deviations. The 8 th sternite is identical, in particular. Thus it should be identified as a local form of C. indigum, without reaching the status of sub-species.	en	Yokoi, Yaheita (2019): Callidiopini beetles in the collection of the Zoologische Staatssammlung München (ZSM) - Part I.
