Bottom line, Acanthoferonia, as cool as it is, must be treated as a subgenus. Here is a draft abstract of the paper I am writing up now.
NOTHING WRITTEN HERE CAN BE CONSTRUED AS BEING PUBLISHED IN THE SENSE OF THE ICZN.
Bayesian analysis of a combined matrix of four partial gene sequences (28S rDNA, wg, CAD and COI mtDNA) from exemplars of all genera of the Notonomus-series of pterostichine carabid beetles (sensu Moore (1965)) and 12 of 17 informal groups of Notonomus Chaudoir, 1862 (groups sensu Sloane (1913)) strongly supports a clade that requires a redefinition of the genus Notonomus (pp=1.0). All but one of exemplar species of Sarticus Motschulsky, 1865 included in the analysis fall outside of Notonomus and form a very highly supported monophyletic group. Exemplar species of the South American genus Parhypates Motschulsky, 1866, included as outgroup taxa, also form a well-supported clade. The combined data analysis places Sarticus as the sister group of Notonomus, however, support is low for this relationship (pp=0.61). Individual gene analyses indicated that wg is in conflict with all other loci and analysis of data exclusive of wg places Parhypates as sister to Notonomus with very high support (pp=0.98). Notonomus is redefined to include all species currently placed in Notonomus, two species of Sarticus (S. blackburni (Sloane) and S. impar (Sloane)), all species of Leiradira Castelnau, 1867, Conchitella Moore, 1962, Loxodactylus Chaudoir, 1865 and Acanthoferonia Moore, 1965. The latter four genera are herein treated as subgenera of Notonomus. Leiradira is also treated as a subgenus and species are nested within Notonomus forming a clade that includes Notonomus dimorphicus Darlington and N. flos Darlington. Shared presence and similar form of an elongate flagellum in the male genitalia of these two species, N. (Leiradira) species in the metadira group and some species currently placed in the Notonomus doddi-group suggests they are all closely related. Though results at the genus-level are very robust in this study, relationships within Notonomus remain uncertain. Six new species of subgenus Leiradira from Queensland are described;
Notonomus (Leiradira) thynnefiliarus, N. (L.) vadosus, N. (L.) viridis, N. (L.) spectabilis, N. (L.) iridescens and N. (L.) barri. Two additional species of Notonomus s.l. are described; Notonomus hephaestus from Queensland, which is part of a striking mimicry pair with Notonomus (Leiradira) aurifer Darlington and Notonomus nocturnocappellus, from New South Wales, which represents a unique combination of characteristics for the genus and so effectively represents a unique group. Notonomus (Leiradira) smilodon is proposed as a replacement name for Notonomus (Leiradira) violaceus (Straneo, 1953), which is preoccupied by Notonomus violaceus (Castelnau, 1834). Notonomus parallelomorpha Chaudoir 1878 is an available name to replace Notonomus auricollis (Castelnau 1867), which is preoccupied by Notonomus (Leiradira) auricollis Castelnau 1867. Leiradira blandula Tschitscherine, 1898 is newly synonymized with Notonomus (Leiradira) auricollis (Castelnau 1867). An identification key to species in the subgenus Leiradira and newly described species placed as Notonomus incertae sedis is provided.
