The Serbian fauna of the superfamily Scarabaeoidea is relatively well-known compared to the neighbouring countries. Many common species known from Serbia’s neighbouring countries are not recorded in Serbia, despite the richness of the country’s habitats, such as high-mountain meadows, pastures, deep gorges, riverbanks (including the exceptionally valuable sandy banks of the Danube) and old forests. Therefore, we aim to supplement the current information on the distribution of the species of the Serbian scarabaeoid beetles. The presented scarabaeoid beetles were caught during seven expeditions in 2013, 2017, 2018, 2019 (two expeditions), 2021, and 2022. As a result, 2031 beetles belonging to 120 species and five families of the superfamily Scarabaeoidea (Geotrupidae, Trogidae, Lucanidae, Glaphyridae, Scarabaeidae) were observed. In less than two months of the faunistic study, the authors confirmed the occurrence in Serbia of 49.5% of the scarabaeoid species previously known from this country and added 13 new species that had not been previously recorded: Eulasia pareyssei (Brullé, 1832), Pygopleurus apicalis (Brullé, 1832), Melinopterus reyi (Reitter, 1892), Nimbus johnsoni (Baraud, 1976), Planolinoides borealis (Gyllenhal, 1827), Copris hispanus Linnaeus, 1764, C. umbilicatus Abeille de Perrin, 1901, Cheironitis furcifer (P. Rossi, 1792), Onthophagus dellacasai Pittino & Mariani, 1981, O. similis (Scriba, 1790), Chaetonyx schatzmayri Mariani, 1946, Holochelus costulatus (Frivaldszky, 1835), and Omaloplia corcyrae (Baraud, 1965). Eight species and one subspecies typical for the Balkan Peninsula were also found: Jekelius punctulatus (Jekel, 1866), Pygopleurus apicalis, P. chrysonotus (Brullé, 1832), Onthophagus dellacasai, Chaetonyx robustus robustus Schaum, 1862, Ch. schatzmayri, Omaloplia corcyrae, O. illyrica (Baraud, 1965), and Triodontella dalmatica (Baraud, 1962). Thus, the number of currently known scarabaeoid species in Serbia has increased to 229. Our results indicate insufficient knowledge of the Scarabaeoidea of Serbia. Therefore, further research and new expeditions to Serbia are highly desirable. High-mountain and Danubian communities of dung beetles are priceless and deserve protection. Twenty-one species of scarabaeoid beetles are illustrated.

The Montenegrin fauna of the superfamily Scarabaeoidea is not satisfactorily studied. This is evidenced by the small number of species from this superfamily reported from Montenegro, despite the richness of the country’s habitats, especially high-mountain meadows, pastures, lush canyons, riverside, coastal dunes and old forests. Moreover, significant is the greater number of species of scarabaeoid beetles in neighbouring countries. Therefore, we aim to supplement the current information on the distribution of the taxa of the superfamily Scarabaeoidea in the country. The presented scarabaeoid beetles were caught during three expeditions: the first in May/June 2019, the second in May/June 2021, and the third in July 2021. As a result of this study, we have collected 2130 beetles belonging to 107 species and five families of the superfamily Scarabaeoidea: Geotrupidae, Trogidae, Lucanidae, Ochodaeidae and Scarabaeidae. The 28 days of the faunistic study confirmed the occurrence in Montenegro of 54.2% of the scarabaeoid species hitherto known from this country and added 16 new species that had not been previously recorded: Odonteus armiger (Scopoli, 1772), Trox sabulosus (Linnaeus, 1758), Ochodaeus integriceps Semenov, 1891, Agrilinus convexus (Erichson, 1848), Melinopterus reyi (Reitter, 1892), M. sphacelatus (Panzer, 1798), Phalacronothus biguttatus (Germar, 1824), Trichonotulus scrofa (Fabricius, 1787), Psammodius nocturnus Reitter, 1892, Platytomus tibialis (Fabricius, 1798), Pleurophorus mediterranicus Pittino & Mariani, 1986, P. pannonicus Petrovitz, 1961, Rhyssemus berytensis Marseul, 1878, Onthophagus ovatus (Linnaeus, 1767), Rhizotrogus aestivus (Olivier, 1789) and Chaetopteroplia segetum (Herbst, 1783). Six species and three subspecies that are typical for the Balkan Peninsula were also found: Trypocopris alpinus balcanicola (Mikšić, 1954), Onthophagus panici Petrovitz, 1964, Amphimallon solstitiale simplicissimum (Müller, 1902), Omaloplia illyrica (Baraud, 1965), Triodontella dalmatica (Baraud, 1962), Chaetopteroplia segetum straminea (Brullé, 1832), Anomala matzenaueri Reitter, 1918, Exomala adriatica (Petrovitz, 1968) and Oxythyrea dulcis Reitter, 1899. Thus, the number of currently known scarabaeoid species in Montenegro has increased to 184. Twenty-four species of scarabaeoid beetles are illustrated. Our results indicate insufficient knowledge of the Scarabaeoidea of Montenegro and, at the same time, their diversity and the presence of rare species among them. High-mountain and coastal communities of coprophagic scarabaeoid beetles, as well as communities of scarabaeoid beetles inhabiting coastal dunes, are especially valuable, worthy of protection. Therefore, further research and new expeditions to Montenegro are highly desirable.

Species of the genus Rhyparus Agassiz, 1846 (Coleoptera: Scarabaeidae: Aphodiinae) from the Philippines are reviewed. Altogether six species are recorded, including description of two species new to science from Mindanao Island: R. flavohirtus sp. nov. and R. mindanaoensis sp. nov. Rhyparus gracilis Arrow, 1905 and R. barclayi Masumoto, Ochi & Ho, 2019 are recorded from the Philippines for the first time. All species are diagnosed and illustrated, including photos of epipharyngi and male genitalia. A key to Philippine Rhyparus species is provided.
