- Female specimens will key out as O. orphnoides Bates (couplet 7(1 9)) in Genier and Howden (1999). However, specimens can easily be separated from O. orphnoides by the presence of a strong and laterally tuberculate transverse carina on the vertex and coarse and sharply defined pronotal punctures.
- To determine if characters of the female O. mirabilis agreed with the phylogenetic hypothesis presented in Genier and Howden 1999, the data matrix was analyzed again with the previously unknown characters included. The addition of the female of O. mirabilis did not change the most parsimonious tree previously obtained.
- Biology. Onthophagus mirabilis is now known from one locality in Ecuador and one locality in Colombia (Valle del Cauca). The site in Colombia is located in a humid 612 tropical montane forests, at an elevation between 1,575-1,600 m. Colombian specimens were almost exclusively caught using unbaited or rotten fruit baited pitfall traps. Only one specimen each was collected by using flight intercept, human dung baited pitfall, or rotten egg baited pitfall traps. We suspect that these instances were essentially random, equivalent to un-baited pitfall traps. In the Reserva Forestal de Yotoco, rotten fruit traps (a mix of banana, orange, guava, and mango) were set in June 1999. Other traps were baited with rotten fruits found locally on the forest floor, and others with fungi. However, no specimens of O. mirabilis were attracted to traps baited with fungi. Onthophagus mirabilis was collected with only one other species of Scarabaeinae (Ateuchus sp.) in traps with mixed fruit, and in traps baited with figs (Ficus sp., Moraceae).
