Fig. 28. Current distribution of Streblopus van Lansberge, 1874 plotted on a Middle Miocene palaeomap (~ 15 million years ago). Presently, both species of Streblopus are largely isolated from one another by means of the South America Dry Diagonal that separates the humid forests of the Amazon Basin from the Atlantic Forest on the South American eastern coast. This disjunct distribution is probably a result of the fragmentation of an once much more widely-distributed genus, which crossed the Dry Diagonal from the Atlantic Forest to southwestern Amazonia through forest corridors connecting those two biomes during periods of warmer climate over the past 25 million years. When the climate cooled and the tropical forests retreated, the open and drier environments of the Dry Diagonal advanced, and the populations of Streblopus in the Atlantic Forest and in the Amazon became isolated. It is known that the Middle Miocene experienced the highest temperatures of the last 20 million years (Zachos et al. 2001), and perhaps it was during its ʻclimate optimumʼ about 15 million years ago that the Amazonian and the Atlantic Forest populations of Streblopus were connected for the last time. Palaeomap modified from Scotese (2016).
Fig. 26. Genital segment. A. Streblopus opatroides van Lansberge, 1874. B. S in Systematics of the enigmatic South American Streblopus Van Lansberge, 1874 dung beetles and their transatlantic origin: a case study on the role of dispersal events in the biogeographical history of the Scarabaeinae (Coleoptera: Scarabaeidae)
Fig. 26. Genital segment. A. Streblopus opatroides van Lansberge, 1874. B. S. punctatus (Balthasar, 1938). Note that the medial sclerotized plate is larger and more sclerotized in S. punctatus than in S. opatroides; other differences refer to their lateral arches (indicated by blue arrows), which are concave in S. opatroides and more or less straight in S. punctatus, and the posterior arms of the MSP (indicated by red arrows), which are well developed and separated by a deep ʻU-shapeʼ in S. punctatus and only slightly indicated in S. opatroides. Abbreviations: LSP = lateral sclerotized plate; MSP = medial sclerotized plate.

Abbreviations: A = axial sclerite; Rp = raspule; SA = subaxial sclerite; SRP = superior right peripheral sclerite; T = temones.
