phylogeny of the stink bug tribe chlorocorini heteroptera Pentatomidae based on dna and morphological data the evolution of key phenotypic traits
bioRxiv, 2020Co-Authors: Bruno C Genevcius, David A. Rider, Caroline Greve, Samantha Koehler, Rebecca B Simmons, Jocelia Grazia, Cristiano F SchwertnerAbstract: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, while 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 favoring anti-predatory behavior 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.

Stink bugs (Hemiptera, Heteroptera, Pentatomidae) of the Catimbau National Park, a protected area in Brazil's largest dry forest.
Zootaxa, 2019Co-Authors: Lucas Cavalcanti Brito, Jocelia Grazia, Kim Ribeiro BarãoAbstract:The knowledge about insects of the Caatinga, the largest seasonally dry tropical forest of South America, is largely incomplete. Aiming at reducing this knowledge gap, we conducted the first inventory of Pentatomidae (Hemiptera: Heteroptera) for the Catimbau National Park and Pernambuco State. After 48h of sampling, during dry and rainy seasons, we collected 168 specimens, comprising 12 species and 10 genera of Pentatomidae. Cyptocephala alvarengai , Dichelops ( Diceraeus ) caatinguensis , and Tetragonotum megacephalum are apparently restricted to the Caatinga biome and represented 40% of the collected specimens in our sample. The other nine species are widespread in South America and the majority are associated with agroecosystems.

Diversity of Stink Bugs (Pentatomidae) Associated with Canola: Looking for Potential Pests.
Neotropical entomology, 2018Co-Authors: Filipe Michels Bianchi, Jocelia Grazia, A. L. Marsaro Júnior, Paulo Roberto Valle Da Silva Pereira, Antônio R. PanizziAbstract:Canola (Brassicaceae: Brassica spp.) is an important feedstock for biodiesel production and a potential ingredient for use in the food industry. In different continents, various arthropod pests damage canola plants. Stink bugs (Heteroptera: Pentatomidae) are present in all zoogeographical regions, and many species are recognized by their economic importance as crop pests. Our aim was to describe the composition, structure, and diversity of the assemblage of stink bugs sampled on canola in southern Brazil. A total of 878 pentatomids were captured, belonging to 27 species. The dominant species were Euschistus heros (F.) (n = 439), Dichelops furcatus (F.) (n = 160), and Nezara viridula L. (n = 79). The species richness estimators indicated the samples correspond from 79.7 to 93.1% of the richness estimated. Comparing canola to other monocultures, the richness of Pentatomidae was much superior. Otherwise, when compared to studies conducted in native vegetation and urban fragments, the richness is similar, and sometimes higher. This relatively high number of associations brings out the vulnerability of the canola fields according to the expansion of its cultivated area. Nine species of Pentatomidae are recorded on canola for the first time in Brazil. The most abundant species reported here are often stressed as stink bugs of economic importance in agro-ecosystems. The economic importance of each species varies greatly depending on the plant attacked. Detailed studies are needed to evaluate the damage caused to canola by stink bugs.

Diversity of the external thoracic scent efferent system of Carpocorini (Heteroptera: Pentatomidae) with character selection for phylogenetic inference
Zoologischer Anzeiger, 2017Co-Authors: Kim Ribeiro Barão, Augusto Ferrari, Carolina V.k. Adami, Jocelia GraziaAbstract:Abstract The metathoracic glands of Heteroptera open through paired orifices ventrally on the metepisternum. Externally, the mesopleura and the metapleura of Pentatomidae are equipped with the external scent efferent system (ESES), structures involved in spreading the metathoracic glands secretions. The ESES of the highly diverse Carpocorini (Pentatomidae) was studied under light and scanning electron microscopy. We present a summary of the morphological variation of the ESES found as a list of character statements, intending to facilitate character coding to assessing phylogenetic relationships among carpocorine genera. The variation on ESES is discussed in the light of the current understanding of Carpocorini systematics. We identified 27 characteristics that were coded for 90 species (63 genera), all characters and character states are illustrated. Three general patterns were recognized: a well-developed evaporatorium on meso- and metapleuron, reaching the lateral margin o mesopleuron; a poorly developed evaporatorium on meso- and metapleuron; and an intermediate condition. Several genus-groups proposed within the tribe, based on general and genital morphology, have consistent ESES patterns. ESES morphology is informative at genus level as congeneric species do not show or show little variation on ESES structures. We suggest ESES should be further investigated and included in phylogenetic analyses in Pentatomoidea.

Acrosternum heegeri Fieber, 1861 (Hemiptera: Heteroptera: Pentatomidae), another Mediterranean bug expanding to the north.
Zootaxa, 2017Co-Authors: Balázs Károlyi, Dávid RédeiAbstract:Acrosternum heegeri Fieber, 1861 (Hemiptera: Heteropera: Pentatomidae: Pentatominae: Pentatomini), a Holomediterranean-Turanian shield bug species, is recorded for the first time from Hungary, representing the first known occurrence of the species in Central Europe. The species is illustrated, its geographic distribution is reviewed. The occurrence of A. heegeri in two localities in Budapest, regular records from one of the localities in the years 2015 and 2016, and the finding of an overwintering individual indicate the presence of a stable population in the city; the species is probably already established and it is locally abundant. Its further spread in Europe is expected.
