“…The other group was made up of P. howardi , P. chinai , P. humeralis , P. rufotuberculatus , P. lignarius , P. geniculatus , P. noireaui , and P. megistus , and was associated with the Andean uplift and marine invasions during the Miocene (Pebas Lake), with river channels, swamps, and a characteristic savanna climate [ 67 ].…”

“…This evolutionary event coincided with the major adaptive radiation of the Didelphimorphia (Ameridelphia, marsupials) in the Late Cretaceous/Early Cenozoic. These taxa diversified when they crossed Australia/America and disappeared from Europe [ 67 , 75 ]. This would explain why some of its species, such as D. marsupialis , the primary reservoir of T. cruzi in the Americas, are found in a wide range of biomes in the Neotropic [ 11 ].…”

Panstrongylus is a Neotropical taxa of 16 species, some more widespread than others, that act as vectors of Trypanosoma cruzi, the etiologic agent of Chagas disease (CD). This group is associated with mammalian reservoir niches. There are few studies of the biogeography and niche suitability of these triatomines. Using zoo-epidemiological occurrence databases, the distribution of Panstrongylus was determined based on bioclimatic modelling (DIVA GIS), parsimonious niche distribution (MAXENT), and parsimony analysis of endemic species (PAE). Through 517 records, a wide presence of P. geniculatus, P. rufotuberculatus, P. lignarius, and P. megistus was determined and recorded as frequent vectors of T. cruzi in rainforest habitats of 24–30 °C. These distributions were modeled with AUC >0.80 and <0.90, as well as with the seasonality of temperature, isothermality, and precipitation as relevant bioclimatic variables. Individual traces for each taxon in Panstrongylus—1036 records—showed widely dispersed lines for frequent vectors P. geniculatus, P. lignarius, P. rufotuberculatus, and P. megistus. Other occasional vectors showed more restricted dispersal, such as P. howardi, P. humeralis, P. lenti, P. lutzi, P. tupynambai, P. noireaiui, and P. chinai. Areas of defined environmental variation, geological change, and trans domain fluid fauna, such as the American Transition Zone and the Pacific Domain of Morrone, had the highest Panstrongylus diversity. Pan-biogeographic nodes appear to be areas of the greatest species diversity that act as corridors connecting biotopes and allowing fauna migration. Vicariance events in the geologic history of the continent need to be investigated. The geographical distribution of Panstrongylus overlapped with CD cases and Didelphis marsupialis/Dasypus novemcinctus presence, two important reservoirs in Central and South America. The information derived from the distribution of Panstrongylus provides knowledge for surveillance and vector control programs. It would increase information on the most and less relevant vector species of this zoonotic agent, for monitoring their population behavior.

“…Las provincias biogeográficas y los tipos de vegetación en donde habitan estas especies, así como las hipótesis biogeográficas de Ischnorhininae, llevan a sugerir que el patrón de distribución de estos insectos es concordante con el cenocrón Mesoamericano de Montaña (Halffter, 2017). Los taxones que siguen este patrón se distribuyen principalmente en bosques de montaña, mesófilos y de pino-encino, además de que se caracterizan por originarse a partir de linajes sudamericanos, que colonizaron América Central y posteriormente se dispersaron en los sistemas montañosos de la Zona de Transición Mexicana (Juárez-Barrera et al, 2020;Morrone, 2019). De acuerdo con esto, la distribución actual de los géneros de Cercopidae americanos (= Ischnorhininae) ha sido explicada por una combinación de varios eventos de dispersión y vicarianza, a partir de su área de distribución ancestral, que se estima fue el noroeste de Sudamérica, zona que corresponde al límite septentrional de la subregión caribeña del Neotrópico (Carvalho y Webb, 2005;Cryan y Svenson, 2010;Morrone, 2001;Paladini et al, , 2018.…”

El complejo Ocoaxo de los pinos está integrado por 3 especies (O. assimilis, O. cardonai, O. varians) que se alimentan de la savia de las acículas de Pinus spp. provocando clorosis y su eventual caída. Los crecimientos poblacionales de estos insectos han provocado la defoliación de grandes superficies de bosque en varias localidades del país, por lo cual se les ha dado el estatus de plaga, a pesar de que aún se desconocen aspectos básicos de su biología y distribución. En el presente trabajo se analizaron los registros de especímenes depositados en colecciones entomológicas y bases de datos en línea, que permitieron definir el espacio geográfico donde estas especies están presentes en interacción con los ecosistemas de México, además de proporcionar el espectro alimenticio de su estado adulto, identificar los factores ambientales que potencialmente están asociados a su presencia, así como conocer el periodo en el que se encuentran a lo largo del año. Los análisis de estos datos también permitieron generar hipótesis espaciales de su distribución, estimar los límites de las áreas donde se han reportado y reconocer áreas potenciales para su monitoreo.

“…A cenocron is a set of taxa that share a geographic origin, that dispersed during a given time interval and diversified in a particular area (Fernandes et al., 2019; Morrone, 2020). The age of these dispersal events has been established previously using the taxon's distribution size, niche width, phylogenetic affinities, and differential species richness between regions (Juárez‐Barrera et al., 2020), under the assumption that phylogenetic inertia controls the spatial distribution of the biota (Halffter & Morrone, 2017; Morrone, 2020). Consequently, the distinctive biota of the MTZ has been assembled by the successive dispersal events of cenocrons that arrived from both North and South America (Halffter & Morrone, 2017), the oldest being the Mexican Plateau cenocron.…”

The Mexican Transition Zone is a biogeographically complex area where old and new lineages of Neotropical and Nearctic affinities overlap. Its biota was assembled by successive dispersal events of cenocrons, which are sets of taxa that dispersed during a given time interval from both North and South America and then diversified in the area. The Mexican Plateau cenocron, with Neotropical affinities, is found in temperate and dry climates in the Nearctic region. We hypothesised that it underwent an adaptive shift in environmental niche. We tested this hypothesis using a phylogenetic comparative framework, measuring phylogenetic signal and fitting to single optima macroevolutionary models, and an Ornstein‐Uhlenbeck macroevolutionary model with multiple optima. We used phylogenetic and distributional information of the tribe Phanaeini to assess whether there exists a distinction in conservatism between the earliest (Mexican Plateau) and most recent (Typical Neotropical) cenocrons within the Mexican Transition Zone (MTZ) as this tribe stands as a classic example of the dispersal and diversification patterns of cenocrons originating in the Neotropics. We identified different shifts in environmental requirements that match the niche description of the Mexican Plateau cenocron, suggesting that it was established through multiple adaptive shifts in the Mexican Transition Zone.
