On the basis of a newly performed cladistic analysis a new classification of the representatives of two Afrotropical tenebrionid genera, Ectateus Koch, 1956 and Selinus Mulsant & Rey, 1853 sensu Iwan 2002a, is provided. Eleoselinus is described as a new genus. The genus Monodius, previously synonymized with Selinus by Iwan (2002), is redescribed and considered as a separate genus. Following new combinations are proposed: Ectateus calcaripes (Gebien, 1904), Monodius laevistriatus (Fairmaire, 1897), Monodius lamottei (Gridelli, 1954), Monodius plicicollis (Fairmaire, 1897), Eleoselinus villiersi (Ardoin, 1965) and Eleoselinus ursynowiensis (Kamiński, 2011). Neotype for Ectateus calcaripes and lectotypes for E. crenatus (Fairmaire, 1897), E. ghesquierei Koch, 1956 and Monodius malaisei malaisei Koch, 1956 are designated to fix the taxonomic status of these taxa. The following synonymies are proposed: Selinus monardi Kaszab, 1951 and Ectateus latipennis Koch, 1956 with E. crenatus (Fairmaire, 1897). Identification keys are provided to all known species of Ectateus sensu novum, Eleoselinus, Monodius and Selinus sensu novum.

“…This hypothesis was subsequently incorporated into other taxonomic concepts proposed for the Ectateus generic group (Iwan & Banaszkiewicz, ; Kamiński, ). However, the results of a μ‐CT based comparative analysis of the prothoracic skeleton showed that the presence of basal and apophyseal pronotal indentations is not correlated (Kamiński, ; Raś & Kamiński, ). This assumption was adopted during the present phylogenetic study (characters 10–12).…”

“…This publication synthesizes the results of the PhD project of the author conducted at MIIZ, PAS, entitled ‘ Ectateus generic group – phylogeny and classification’. During its realization, the taxonomy of all Afrotropical platynotoid Platynotina species was revised (Kamiński & Raś, ; Iwan & Kamiński, ; Kamiński, , , b, c, ; Kamiński & Iwan, ; Raś & Kamiński, ). This allowed the author to analyse the total variability within the group of interest and to define coherent OTUs for cladistic analysis.…”

Owing to the reinterpretation of its morphological synapomorphies, the taxonomic composition of the Ectateus generic group had been ambiguous. The present study scrutinized all existing taxonomic concepts of the group based on a cladistic analysis of the adult morphology of all of the Afrotropical platynotoid Platynotina genera. The phylogenetic relationships were reconstructed using parsimony and Bayesian inference. The results show that all previous taxonomic concepts of the Ectateus generic group concerned paraphyletic entities. The cladistic analysis revealed the following synapomorphies for the taxon: (1) presence of basal indentations of the pronotal disc, (2) ratio of prothorax width to its maximal height > 6.0, and (3) ratio of maximal height of the prothorax to total height < 0.3. Moreover, phylogenetic studies revealed the existence of the Upembarus generic group, a sister-taxon group to the Ectateus generic group, within the Afrotropical platynotoid Platynotina. Autapomorphic and synapomorphic character mapping show that several taxonomic and nomenclatural changes are needed to consider the particular generic-level entities traditionally assigned to Afrotropical platynotoid Platynotina as monophyletic lineages. The following taxonomic and nomenclatural adjustments are made in this paper: Pteroselinus gen. nov. is erected to accommodate a single species that was previously assigned to Zidalus: Pteroselinus insularis comb. nov. Additionally, the following synonymies are proposed: Anchophthalmops (= Platykochius syn. nov.), Angolositus (= Aberlencus syn. nov., = Platymedvedevia syn. nov.), Glyptopteryx (= Microselinus syn. nov., = Quadrideres syn. nov., = Synquadrideres syn. nov.). In addition, Kochogaster is lowered in rank and is treated as one of the subgenera of Anchophthalmus. Moreover, Pseudoselinus is treated as a subgenus of Upembarus. An identification key to all Afrotropical platynotoid Platynotina genera and subgenera is presented. Zoogeographical analyses revealed the following dispersal barriers for the Ectateus generic group: (1) the Sahara (northern barrier); (2) the dry ecosystems of Botswana, Namibia, and South Africa (southern barrier); and (3) the Congolian rainforests (internal distributional gap). The ancestor of the taxon probably originated in East African ecoregions that predominantly contained wattletrees (acacias) and Commiphora Jacq. Moreover, past climate changes seem to have had a great impact on the observed generic distribution.
