Rhytiphora Audinet-Serville, 1835

Type species Lamia rugicollis Dalman, 1817 by monotypy (Fig. 2K). Both the genus and species name (Greek and Latin, respectively) refer to the rugose pronotum. A full description and list of generic synonyms can be found in Ślipiński & Escalona (2013).

Based on molecular evidence, the Australian Rhytiphora species fall into two phylogenetic clades (Ashman et al. 2022b); characteristic morphological traits are listed below. Within these two clades, species’ relationships are not consistent with former taxonomic groupings (e.g. previously recognised genera and subgenera; Ashman et al. 2022a); therefore, we do not use any subgeneric divisions in this paper. Four species contradict their clades’ typical morphology (Ashman et al. 2022a): Rhytiphora piligera Macleay, 1826 and R. pustulosa Pascoe, 1864 in clade 1; R. crassicollis Pascoe, 1864 and R. fulvescens Pascoe, 1863 in clade 2. Both clades have at least one New Guinean endemic species. Clade 2 also contains a species group with punctate antennal scapes (all other Rhytiphora species have smooth scapes): R. argentata Breuning, 1938, R. browni McKeown, 1938, R. dallasii Pascoe, 1869, and R. macleayi Lea, 1912 .
