“…4). Our results agree with other comparative studies that revealed strong interspecific variability for these characters in other groups of pentatomids (Kment & Vilímová, 2010;Barão et al, 2017). Interestingly, the length of the ostiolar ruga is one of the characters widely used for the classification (and diagnostics) within Pentatomidae (Rider et al, 2018), and its homoplastic nature has already been suggested in other phylogenetic studies (Barcellos & Grazia, 2003;Memon et al, 2011).…”

23Pentatomidae is the fourth largest family of true bugs, comprising nine subfamilies and 24 over 40 tribes. Few tribes in the family have been studied in a phylogenetic context, and 25 none of them have been examined using molecular data. Here, we conduct a 26 phylogenetic study of the tribe Chlorocorini (Pentatominae) combining 69 27 morphological characters and five DNA loci in a bayesian framework. The tribe stands 28 out as the most diverse tribe in the subfamily Pentatominae which occurs exclusively in 29 the New World. Chlorocorini was proposed as a probable monophyletic group based on 30 synapomorphies found on nearly all body parts, including the spined humeral angles of 31 the pronotum, a dorsal projection on the apices of each femora, the absence of an 32 abdominal spine and the presence of well-developed, paired projections in the male 33 genitalia (hypandrium). Here, we provide solid evidence that the tribe as currently 34 recognized is not monophyletic based both on DNA and morphological data. The 35 genera Arvelius Spinola and Eludocoris Thomas were consistently placed outside of the 36Chlorocorini, while the remaining genera were found to form a monophyletic group. 37 Furthermore, all morphological diagnostic characters for the tribe were homoplastic, 38 except for the developed hypandrium. Lastly, we also provide a preliminary glimpse of 39 main phylogenetic relationships within the Pentatomidae, which indicate that most of 40 the included subfamilies and tribes are not monophyletic. Our results suggest that the 41 current classification of Pentatomidae is not completely adequate to reflect its 42 evolutionary history, and we urge for a complete phylogeny of the family. 43 44

Pentatomidae is the third largest family of true bugs, comprising over 40 tribes. Few tribes have been studied in a phylogenetic context, and none of them have been examined using molecular data. Moreover, little is known about the evolution of key morphological characters widely used in taxonomic and phylogenetic studies at multiple levels. Here, we conduct a phylogenetic study of the tribe Chlorocorini (Pentatominae) combining 69 morphological characters and five DNA loci. We use the inferred phylogeny to reconstruct the evolution of key morphological characters such as the spined humeral angles of the pronotum, a dorsal projection on the apices of the femora and characters of male genitalia. We provide solid evidence that the tribe as currently recognized is not monophyletic based both on DNA and morphological data. The genera Arvelius Spinola and Eludocoris Thomas were consistently placed outside of the Chlorocorini, whereas the remaining genera were found to form a monophyletic group. We also show that nearly all morphological diagnostic characters for the tribe are homoplastic. The only exception is the development of the hypandrium, which contrary to expectations for genital traits, showed the slowest evolutionary rates. In contrast, the most rapidly evolving trait is the length of the ostiolar ruga, which may be attributed to selection favouring anti‐predatory behaviour and other functions of its associated scent glands. Lastly, we also provide a preliminary glimpse of the main phylogenetic relationships within the Pentatomidae, which indicates that most of the included subfamilies and tribes are not monophyletic. Our results suggest that the current subfamily‐level classification of Pentatomidae is not adequate to reflect its evolutionary history, and we urge for a more complete phylogeny of the family.

“…To collect the defensive odors from the two hemipteran species, we used similar methods described in Vickers and Taylor 18 where we placed each bug in a 3.5 cm diameter petri dish with filter paper lining the bottom and shook it for approximately 10 s. When disturbed, both the leaf-footed bugs and the stink bugs readily released their odors by spraying them from their thoracic scent glands 29 , 44 . For the Asian ladybird beetles, we used forceps to gently pull on their legs, which caused “reflex bleeding” 33 , whereby odorous liquid was released onto the filter paper.…”

Hemipteran defensive odors trigger predictable color biases in jumping spider predators

Multimodal warning displays often pair one signal modality (odor) with a second modality (color) to avoid predation. Experiments with bird predators suggest these signal components interact synergistically, with aversive odors triggering otherwise hidden aversions to particular prey colors. In a recent study, this phenomenon was found in a jumping spider (Habronattus trimaculatus), with the defensive odor from a coreid bug (Acanthocephala femorata) triggering an aversion to red. Here, we explore how generalizable this phenomenon is by giving H. trimaculatus the choice between red or black prey in the presence or absence of defensive odors secreted from (1) eastern leaf-footed bugs (Leptoglossus phyllopus, Hemiptera), (2) grass stinkbugs (Mormidea pama, Hemiptera), (3) Asian ladybird beetles (Harmonia axyridis, Coleoptera), and (4) eastern lubber grasshoppers (Romalea microptera, Orthoptera). As expected, in the presence of the hemipteran odors, spiders were less likely to attack red prey (compared to no odor). Unexpectedly, the beetle and grasshopper odors did not bias spiders away from red. Our results with the hemipteran odors were unique to red; follow-up experiments indicated that these odors did not affect biases for/against green prey. We discuss our findings in the context of generalized predator foraging behavior and the functions of multimodal warning displays.
