“…In the state of Bahia, the existence of triatomines has been reported since 1911, and between 2008 and 2017, it presented the highest mortality rate from Chagas disease among other states in the Northeast region, with P. megistus being the predominant species found (RIBEIRO JR et al, 2022).…”

The Rhodniini tribe is composed of the genera Rhodnius and Psammolestes. From phylogenetic data, Rhodnius spp. were grouped into three large groups (pallescens, pictipes and prolixus). This genus is considered paraphyletic, since species in the prolixus group are evolutionarily closer to Psammolestes spp. than of the Rhodnius groups. Based on the above, we present a chronological mini-review related to the main phylogenetic and molecular taxonomy studies carried out in the genus Rhodnius. From the data presented, it is clear that: i. the Rhodniini tribe is a monophyletic group; ii. there are three well-defined monophyletic groups in the tribe Rhodniini (prolixus, pictipes and pallescens); iii. the evolutionary relationship between these groups needs to be better defined by phylogenetic studies combining different markers and, above all, increasing intra and interspecific sampling of the genus Rhodnius (with emphasis on species that have never been studied molecularly); iv. the genus Rhodnius is a paraphyletic group in relation to Psammolestes; v. the specific status of some Rhodnius species (such as R. milesi and R. zeledoni) needs to be assessed by integrative taxonomy; vi. paraphyletic lineages of R. robustus need to be described as new species; viii. the strains of R. ecuadoriensis and R. pallescens, as well as Rhodnius aff. R. pictipes from Sierra Nevada, Colombia needs to be studied by integrative taxonomy and described as new species; and, finally, viii. phylogenetic systematics is essential for the taxonomy of Rhodnius.

“…In addition, T. infestans residual foci have been detected in Brazil after certification. 7 Overall, these data indicate that elimination of non-native populations of “primary” vectors is feasible, but has many challenges.…”

“… 11 In the state of Bahia, there was a clear reduction in the distribution of T. infestans and an increase in the relative abundance and distribution of T. sordida and T. pseudomaculata after 40 years of the vector-control program. The high frequency of native triatomine species invading houses in the Americas in recent years 7 , 12 , 13 highlights the need to reinforce entomological surveillance actions to prevent CD.…”

BACKGROUND Kissing bugs are the vectors of Trypanosoma cruzi , the etiological agent of Chagas disease (CD). Despite their epidemiological relevance, kissing bug species are under sampled in terms of their diversity and it is unclear what biases exist in available kissing bug data. Under climate change, range maps for kissing bugs may become less accurate as species shift their ranges to track climatic tolerance. OBJECTIVES Quantify inventory completeness in available kissing bug data. Assess how well range maps are at conveying information about current distributions and potential future distributions subject to shift under climate change. Intersect forecasted changes in kissing bug distributions with contemporary sampling gaps to identify regions for future sampling of the group. Identify whether a phylogenetic signal is present in expert range knowledge as more closely related species may be similarly well or lesser understood. METHODS We used species distribution models (SDM), specifically constructed from Bayesian additive regression trees, with Bioclim variables, to forecast kissing bug distributions into 2100 and intersect these with current sampling gaps to identify priority regions for sampling. Expert range maps were assessed by the agreement between the expert map and SDM generated occurrence probability. We used classical hypothesis testing methods as well as tests of phylogenetic signal to meet our objectives. FINDINGS Expert range maps vary in their quality of depicting current kissing bug distributions. Most expert range maps decline in their ability to convey information about kissing bug occurrence over time, especially in under sampled areas. We found limited evidence for a phylogenetic signal in expert range map performance. MAIN CONCLUSIONS Expert range maps are not a perfect account of species distributions and may degrade in their ability to accurately convey distribution knowledge under future climates. We identify regions where future sampling of kissing bugs will be crucial for completing biodiversity inventories.
