TY - JOUR A1 - Solís, Ángel A1 - Kohlmann, Bert T1 - New synonyms and records of Costa Rican and Panamanian dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) T2 - Insecta Mundi N2 - To better understand the dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) biodiversity of Costa Rica and Panama, new synonyms, records, distributions, and updates are presented. This paper analyzes the distribution and taxonomy of Phanaeus olsoufieffi Balthasar, 1939 in Panama and establishes the following new subjective synonym: Phanaeus panamensis Moctezuma and Halffter, 2021 = Phanaeus olsoufieffi Balthasar, 1939. Color morphs of Phanaeus pyrois Bates, 1887 in Costa Rica are analyzed. The Costa Rican distribution of Onthophagus bidentatus Drapiez, 1819 and O. marginicollis Harold, 1880 is studied. Onthophagus bidentatus is recorded for Costa Rica for the first time. A population analysis of barcode mtDNA, color morphs, and morphological and genitalia characters for different body sizes of Onthophagus cyanellus is undertaken. An mtDNA barcode tree is presented to assess the molecular identity of O. cyanellus resulting in the reaffirmed subjective synonymy, Onthophagus mesoamericanus Zunino and Halffter, 1988 = O. cyanellus Bates, 1887.
