Oliveira-Correia, J.P.S. et al.: "Taxonomic reassessment of Rhodnius zeledoni Jurberg, Rocha & Galvão: a morphological and morphometric analysis comparing its taxonomic relationship with Rhodnius domesticus Neiva & Pinto"

Background
Rhodnius zeledoni was described from a single specimen. Since its description, doubts have arisen regarding the taxonomic status of this species in relation to Rhodnius domesticus.
Methods
The present study reviewed and compared R. zeledoni with R. domesticus based on morphological analysis and head geometric morphometrics.
Results
Our analysis revealed the absence of distinctive diagnostic characters between the two species at specific levels. Rhodnius zeledoni and R. domesticus show morphological and morphometric similarity, with only minor differences in coloration observed between them. Contrary to previous statements, our analysis showed that R. zeledoni and R. paraensis are not closely related species, not corroborating previous studies with such an assumption.
Conclusions
Therefore, we formally propose R. zeledoni as a junior synonym of R. domesticus.

Carrenho R. et al.: "A new synonymy in the Lethaeini of the Neotropics (Heteroptera: Rhyparochromidae), with new country records for Petissius spinipes (Stål)"

Lethaeini is a diverse tribe within Rhyparochromidae, with Lethaeus Dallas being the most speciose genus. This study is focused on the poorly documented Lethaeus lepidus White, the only species in the genus recorded from the Neotropics. Through a reexamination, this species is considered a new synonym of Petissius spinipes Stål. The examined material is sourced from recent field expeditions in natural areas in Brazil, as well as from entomological collections. In addition, the types of the described species were studied from high-definition photographs. The distribution of P. spinipes is updated, indicating that the species is widely distributed in the Neotropics, and filling a large geographic gap with many new locality records. Distribution map including the new records and high-definition illustrations of the species and diagnostic characters are provided. As a result of the findings presented, there are currently no documented representatives of the genus Lethaeus in the New World. With the previouly significant geographical gap between Argentina and Guyana, the 12 new Brazilian state records substantially amplify our undertanding into the species’ range. This emphasizes the indispensable role of entomological collections and the need for dedicaded sampling expeditions to enhance our undertanding of overlooked taxa, as is often the case for Rhyparochromidae.

Fabrikant D. & Novoselska T.: "A peculiar large-eyed aposematic bug Miropictopallium coloradmonens n. gen., n. sp. (Heteroptera: Pentatomomorpha: Yuripopovinidae) from mid-Cretaceous Kachin amber"

Miropictopallium coloradmonens, a new genus and a new species are described and illustrated in the family Yuripopovinidae, based on two specimens from the mid-Cretaceous Kachin amber. The documented diversity of the Yuripopovinidae is thus increased to 15 species in 12 genera. The new genus possesses a number of distinct morphological characteristics for this family including very large eyes, intricate body colour pattern and enlarged scutellum. In addition, the new genus has unfused costal and subcostal veins on the tegmen, a character previously not reported from amber-preserved members of the family. The diagnostic characters of the family are discussed in light of the new descriptions. The newly discovered features prompt some implications towards understanding of the palaeoecology and palaeobiodiversity of the fossil Coreoidea.
