Revision of Australian species of the dung beetle genus Lepanus (Coleoptera: Scarabaeidae: Scarabaeinae): description of 10 new species from the L. australis, L. monteithi, and L. villosus species groups
FIGURE 16. Some diagnostic characters of the Lepanus villosus species group. A, lateral view of elytron of Lepanus villosus, white arrow points to deep pit at the base of stria 8; B, lateral view of elytron of Lepanus vestitus, note the absence of any deep pit; C, elytron of Lepanus villosus dotted line showing humeral callus between striae 6 and 7 and white arrow showing depression at base of striae 4 and 5; D, male metatibiae of Lepanus vestitus, notch on inner edge; E, male protibia of Lepanus pseudovillosus, showing typical configuration for the species group including the small comb of setae (grey arrow); F, close up of elytral interval surface of Lepanus reticulatus, showing reticulation of short longitudinal striations; G, close up of elytral interval surface of Lepanus vestitus showing reticulations of fine meshes.
