Abstract.A large-scale phylogenetic study is presented for Cucujoidea (Coleoptera), a diverse superfamily of beetles that historically has been taxonomically difficult. This study is the most comprehensive analysis of cucujoid taxa to date, with DNA sequence data sampled from eight genes (four nuclear, four mitochondrial) for 384 coleopteran taxa, including exemplars of 35 (of 37) families and 289 genera of Cucujoidea. Maximum-likelihood analyses of these data present many significant relationships, some proposed previously and some novel. Tenebrionoidea and Lymexyloidea are recovered together and Cleroidea forms the sister group to this clade. Chrysomeloidea and Curculionoidea are recovered as sister taxa and this clade (Phytophaga) forms the sister group to the core Cucujoidea (Cucujoidea s.n.). The nitidulid series is recovered as the earliest-diverging core cucujoid lineage, although the earliest divergences among core Cucujoidea are only weakly supported. The cerylonid series (CS) is recovered as monophyletic and is supported as a major Cucujiform clade, sister group to the remaining superfamilies of Cucujiformia. Currently recognized taxa that were not recovered as monophyletic include Cucujoidea, Endomychidae, Cerylonidae and Bothrideridae. Biphyllidae and Byturidae were recovered in Cleroidea. The remaining Cucujoidea were recovered in two disparate major clades: one comprising the nitidulid series + erotylid series + Boganiidae and Hobartiidae + cucujid series, and the other comprising the cerylonid series. Propalticidae are recovered within Laemophloeidae. The cerylonid series includes two major clades, the bothriderid group and the coccinellid group. Akalyptoischiidae are recovered as a separate clade from Latridiidae. Eupsilobiinae are recovered as the sister taxon to Coccinellidae. In light of these findings, many formal changes to cucujiform beetle classification are proposed. Biphyllidae and Byturidae are transferred to Cleroidea. The cerylonid series is formally recognized as a new superfamily,

“…One species of Kateretidae ( Anthonaeus agavensis (Crotch)) and 31 different species representing 25 genera of Nitidulidae were included as ingroup (see Table S4). As Kateretidae and Nitidulidae have had an intertwined taxonomic history (Jelínek & Cline, ; Jelínek et al , ) with retention of the former as a subfamily of the latter or as a distinct family itself, A. agavensis was selected to determine whether Kateretidae should or should not be included within Nitidulidae.…”

We present a molecular phylogeny of Nitidulidae based on thirty ingroup taxa representing eight of the ten currently recognized subfamilies. Approximately 10 K base pairs from seven loci (12S, 16S, 18S, 28S, COI, COII and H3) were used for the phylogenetic reconstruction. The phylogeny supports the following main conclusions: (i) Cybocephalidae are formally recognized as a distinct family not closely related to Nitidulidae and its constituent taxa are defined; (ii) Kateretidae are sister to Nitidulidae; (iii) Cryptarchinae are monophyletic and sister to the remaining nitidulid subfamilies; (iv) subfamily Prometopinae stat. res. is reinstated and defined, to accommodate taxa allied to Axyra Erichson, Prometopia Erichson and Megauchenia MacLeay; (v) Amphicrossinae, Carpophilinae and Epuraeinae are shown to be closely related taxa within a well‐supported monophyletic clade; (vi) tribal affinities and respective monophyly within Nitidulinae are poorly resolved by our data and must be more rigorously tested as there was little or no support for prior morphologically based tribes or genus‐level complexes; (vii) Nitidulinae are found to be paraphyletic with respect to Cillaeinae and Meligethinae, suggesting that they should either be subsumed as tribes, or Nitidulinae should be divided into several subfamilies to preserve the status of Cillaeinae and Meligethinae; (viii) Teichostethus Sharp stat. res. is not a synonym of Hebascus Erichson and the former is reinstated as a valid genus. These conclusions and emendations are discussed in detail and presented within a morphological framework.

“…One of these large groups with mixed feeding strategies is sap beetles (Coleoptera: Cucujoidea: Nitidulidae). The largest family in Cucujoidea, Nitidulidae, comprises approximately 350 genera and nearly 4500 recorded species (Jelínek et al, 2010;Ślipiński et al, 2011;Cline et al, 2014). Members of Nitidulidae exhibit one of the most diverse feeding repertoires among all beetle families (Appendix S1), and are present in many microhabitats, such as in living and dead plants, leaf litter, subterranean fungi, social hymenopteran nests (e.g., honeybee and ants) and even in dry carrion of large vertebrates.…”

“…2A). With respect to current phylogenetic relationships (Cline et al, 2014;Robertson et al, 2015), however, Crowson's hypothesis has merit, as Kateretidae are well-known pollen feeders as adults but mostly seed-feeders as larvae (Audisio, 1993;Jelínek & Cline, 2010); the same may be true for Smicripidae (Cline, 2010;Meléndez & Ponce, 2016). Monotomidae is the likely sister taxon to the nitidulid series (e.g., Robertson et al, 2015;Zhang et al, 2018); this family is known from the Jurassic (Cai et al, 2016;Zhang et al, 2018) and exhibit predatory or mycophagous habits (Bousquet, 2010) with many saproxylic species.…”

Evolution of feeding habits of sap beetles (Coleoptera: Nitidulidae) and placement of Calonecrinae

Lee

et al. 2020

Nitidulidae includes some 4500 species under 350 genera in ten subfamilies, making it the most species‐rich family in Cucujoidea. In this study, we present a phylogeny of the family based on five gene regions (COI, 28s, CAD, H3, Wingless) for 73 ingroup taxa representing nine of the ten currently recognized subfamilies of Nitidulidae, including the enigmatic subfamily Calonecrinae. Our results are consistent with a prior molecular study that recovered (i) paraphyletic Nitidulinae with the inclusion of Meligethinae and Cillaeinae and (ii) subfamilial status of Prometopiinae. The molecular phylogenetic position of Calonecrinae is recovered for the first time, as a sister taxon to Epuraeinae. Ancestral state reconstruction of feeding behaviour indicates that the stem group nitidulids were largely mycophagous with transitions to other feeding types independently derived.
