Análise cladística e biogeografia de Ochlerini (Heteroptera, Pentatomidae, Discocephalinae)

Abstract

ABSTRACT. Cladistic analysis and biogeography of Ochlerini (Heteroptera, Pentatomidae, Discocephalinae). A cladistic analysis using 63 characters and 30 genera of the Neotropical tribe Ochlerini Rolston was performed to test their monophyletic condition and to establish a relationship hypothesis. Janeirona Distant, 1911 (Pentatomini) and the tribes Discocephalini and Halyini were included in the ingroup to test their relationship with Ochlerini; Marghita Ruckes, 1964 and Stictochilus Bergroth, 1918 (Pentatomini) were used as outgroups. The obtained strict consensus cladograms indicate that Ochlerini and Discocephalinae are monophyletic groups, but Pentatominae, Halyini+Ochlerini, Pentatomini+Ochlerini, Ochlerus Spinola, 1837, Stalius Rolston, 1992 and Alitocoris Sailer, 1950 are merophyletic groups. Discocephalini and Ochlerini share three synapomorphies: first rostral segment long, attaining prosternum; metasternum with a mesial, longitudinal carina, and dorsal surface of basal third of male proctiger membranous. Ochlerini is supported by one synapomorphy, the flattened dorsal surface of third tarsal segment of hind legs, in females. Biogeographical analysis based on consensus cladograms shows congruent patterns with several vicariant events proposed for the Neotropical region.

Austroperilestidae, a New Family of Damselflies From Early Eocene of Argentina (Insecta: Odonata). Phylogenetic Relationships Within Odonata

“…Other genera having these characters are found within the Discocephalinae (Campos and Grazia 2006;Rolston 1981Rolston , 1990), the Pentatominae: Sciocorini, Myrocheini, Caystrini, and Triplatygini (Kment and Garbelotto 2016) and the Phyllocephalinae (Kamaluddin and Ahmad 1988). The genera of Sciocorini, Myrocheini, and Castrini having broad heads possess the margins of head, pronotum and corium sharp, without lobes and the humeri of pronotum rounded (Kment and Garbelotto 2016), unlike the specimen studied here.…”

Diversity of Pentatomoidea (Hemiptera) in riparian forests of southern Brazil: taller forests, more bugs

“…Grazia 1997;Fortes & Grazia 2005;Campos & Grazia 2006). However, the association of pentatomoids to specific natural habitats is almost largely ignored.…”

Description of the males of Lincus singularis and Lincus incisus (Hemiptera: Pentatomidae: Discocephalinae)

“…Measurements are in millimeters (mm) and follow mainly GARBELOTTO et al (2013) and ROLSTON (1983) for: length and width of eye and pronotal lobe, and interocellar distance. The terminology of BAKER (1931), DUPUIS (1970), CAMPOS & GRAZIA (2006) and GARBELOTTO et al (2013) were adopted for genitalic structures. Photographs were taken using a Nikon AZ100M stereomicroscope and NIS-Elements Advanced Research software.…”
