“…The genus consistently emerged in our results as the sister group of Taurocerus Amyot & Serville; both were more closely related to other genera of Pentatominae than to genera of Chlorocorini. This result is not altogether surprising as both Brailovsky (1981) and Grazia & Barcellos (2005) highlighted similarities between the two genera, including the apical projection on each femur, the abdominal spine present and opposed to the elevated metasternum, and the morphological aspect of the phallus. According to Thomas (1992), Eludocoris should be placed near Loxa and allied genera ( Chlorocoris , Chloropepla and Fecelia ) based primarily on the large body size, the elongate and depressed body shape, the greenish coloration when alive, and the presence of an apical projection on each femur.…”

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.

“…These were thought to be the fused remnants of gonapophyses 9 by Dupuis (1955), and were referred to as the arcus by Schaefer (1968), and thickening of vaginal intima by Grazia and Becker (1997), Grazia et al. (1999), and Grazia and Barcellos (2005), for example.…”

Phylogenetic relationships of family groups in Pentatomoidea based on morphology and DNA sequences (Insecta: Heteroptera)

2008

Phylogenetic relationships within the Pentatomoidea are investigated through the coding and analysis of character data derived from morphology and DNA sequences. In total, 135 terminal taxa were investigated, representing most of the major family groups; 84 ingroup taxa are coded for 57 characters in a morphological matrix. As many as 3500 bp of DNA data are adduced for each of 52 terminal taxa, including 44 ingroup taxa, comprising the 18S rRNA, 16S rRNA, 28S rRNA, and COI gene regions. Character data are analysed separately and in the form of a total evidence analysis. Major conclusions of the phylogenetic analysis include: the concept of Urostylididae is restricted to that of earlier authors; the Saileriolinae is raised to family rank and treated as the sister group of all Pentatomoidea exclusive of Urostylididae sensu stricto; a broadly conceived Cydnidae, as recognized by Dolling, 1981, is not supported; the placement of Thaumastellidae within the Pentatomoidea is affirmed and the taxon is recognized at family rank rather than as a subfamily of Cydnidae, although its exact phylogenetic position within the Pentatomoidea remains equivocal; the Parastrachiinae is treated as also including Dismegistus Amyot & Serville and placed within a broadly conceived Corimelaenidae, the latter group being treated at family rank; the family-group taxa Dinidoridae and Tessaratomidae probably represent a monophyletic group, but the recognition of monophyletic subgroups will benefit from additional representation in the sequence data set; and the Lestoniidae is treated as the sister group of the Acanthosomatidae. The Acanthosomatidae and Scutelleridae are consistently recovered as monophyletic. The monophyly of the Pentatomidae appears unequivocal, inclusive of the Aphylinae and Cyrtocorinae, on the basis of morphology, the latter two taxa not being represented in the molecular data set.

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
