The Neotropical tribe Dorynotini is characterized by a conspicuous tubercle or spine adorning the elytra, which, along with a few other characters, has been used to differentiate its recognized five genera and two subgenera. However, relationships among these taxa and the evolutionary origin of the pronounced tubercle remain speculative. Here we pr...

... and southwest South America. The ancestral character state reconstruction did not recover potential synapomorphies for the clade. However, its internal sister taxa, D. (s.s.) parallela + D. (s.s.) pugionata, share two synapomorphies: mesoscutellum with transverse ridges poorly developed (character 44) (see Supporting Information, Appendix S3, Fig. S102), and parallel asymmetric pretarsal claws. Clade 2 is composed of species endemic to the Greater Antilles, O. humeralis, D. (s.s.) aculeata and P. rubescens (see 'Taxonomic classification' and discussion above). Clade 3 is composed of D. (s.s.) bidens recovered as sister to the subgenus Akantaka. Based on the ACSR, clade 3 shares many ...

Abstract. For 160 years, Anthrenus pimpinellae isabellinus Küster, 1848 has been considered a subspecies of A. pimpinellae Fabricius, 1775. However, habitus shape differs between the subspecies with A. p. isabellinus being broader than A. p. pimpinellae and resembling more closely A. dorsatus Mulsant & Rey, 1868. Here A. p. pimpinellae and A. p. is...

... They are commonly called hispines and tortoise beetles with "hispines" roughly corresponding to the plesiomorphic tribes and tortoise beetles forming the monophyletic crown clade as found in the current phylogenetic hypotheses of this subfamily (Borowiec 1995;Hsiao & Windsor 1999;Chaboo 2007). Some modern tribe-focused phylogenetic hypotheses are available (Fernandes 2011;Shin 2015;López-Pérez et al. 2018;Simões 2018;Leocádio et al. 2020). All these phylogenetic hypotheses are based on molecular and morphological data but include little or no information from immature stages. ...

Pupal morphology has been described for 11 species in six genera of the Neotropical tortoise beetle tribe, Ischyrosonychini Chapuis, 1875. This life stage may offer valuable phylogenetic information but more pupae need to be documented. The pupae of Physonota humilis Boheman, 1856 and P. stigmatilis Boheman, 1854 are described and illustrated for the first time. The pupa of P. humilis does not exhibit lateral scoli on the abdominal segments. Additionally, the body surfaces of P. humilis and P. stigmatilis are somewhat tuberculate, different from other described Physonota Boheman, 1854 pupae. A key to the described pupae of Physonota is provided and 10 phylogenetic character hypotheses are proposed.
... The Neotropical tribe Dorynotini is a monophyletic group characterized by a conspicuous postscutellar tubercle or spine that forms at the elytral suture (Simões et al. 2018). It comprises four genera: Dorynota Chevrolat, 1836, Heteronychocassis Spaeth, 1915, Omoteina Chevrolat, 1836, and Paranota Monrós and Viana, 1949(Borowiec andŚwiętojańska 2018Simões et al. 2018). ...

... All genera presently known to contain subsocial species were included: Acromis (3 spp.), Paraselenis (7 spp.) and Omaspides (7 spp.) and within Eugenysini, Eugenysa (4 spp.) and Agenysa (2 spp.). As the evolutionary relationships among tribes of Cassidinae are partially disputed (Borowiec, 1995;Hsiao & Windsor, 1999;Chaboo, 2007;López-Pérez et al., 2017;Simões et al., 2018), we included in our analysis 19 species representing the five closest tribes: Cassidini, Dorynotini, Goniocheniini, Ischyrosonychini and Omocerini. ...
... (http://tree.bio.ed.ac .uk/software/figtree/). The tribe Dorynotini was chosen because it is arguably the most distantly related to Mesomphaliini among the tribes sampled (Shin, 2015;López-Pérez et al., 2017;Simões et al., 2018). A Bayesian posterior probability ≥0.95, SH-aLRT ≥80 and UFBoot ≥95 were recognized as indicating strong support for a given node (Erixon et al., 2003;Minh et al., 2013Minh et al., , 2017. ...
... Sekerka (2016) stated that phylogenetic analysis of Cassidinae based on adult morphology is dubious as most taxa are sustained by a combination of characters that are, in part, homoplastic. This view has been supported in recent phylogenies, which show that classic morphological characters formerly regarded as synapomorphic have emerged multiple times (López-Pérez et al., 2017;Simões et al., 2018). Thus, based on the recovered results and the lack of morphological synapomorphy to sustain the current classification, we re-establish the synonymy of Eugenysini with the tribe Mesomphaliini. ...

Subsocial behaviour is known to occur in at least 19 insect orders and 17 families of Coleoptera. Within the leaf beetle family, Chrysomelidae, extended maternal care is reported in only 2 of 15 subfamilies: Cassidinae and Chrysomelinae. Although the emergence of subsociality in insects has received much attention, extensive analyses on the evolution of this behaviour based on phylogenetic approaches are missing. Subsociality is recorded in 33 species of tortoise beetles belonging to the tribes Mesomphaliini and Eugenysini. A molecular phylogenetic reconstruction of these tribes and the remaining five Neotropical tribes of cassidine tortoise beetles was used to investigate the evolution of maternal care and to elucidate the phylogenetic relationships among Neotropical cassidine tribes. A phylogeny was constructed using 90 species and three loci from both mitochondrial and nuclear genes (COI, CAD and 28S). Bayesian inference and maximum likelihood analyses based on a concatenated dataset recovered two independent origins, with no evidence of reversal to solitary behaviour. One origin comprises three Mesomphaliini genera tightly associated with Convolvulaceae, and the other consists of the genus Eugenysa Chevrolat (Eugenysini), a small clade embedded within a group feeding exclusively on Asteraceae. A previous hypothesis suggesting dual origins on different host plants was confirmed, whereas other hypotheses based on a phylogenetic reconstruction of Cassidinae could not be sustained. Our analysis also revealed that the tribe Mesomphaliini is a monophyletic taxon if Eugenysini is included, and for this reason, we re‐establish synonymy of both tribes. We also provide nine new records of subsociality for tortoise beetles species.
