Summary We report on what appear to be increasing predation events on nesting Thick-billed Parrots Rhychopsitta pachyrhyncha. Thick-billed Parrots are classified as ‘Endangered’ and their seasonal breeding range is restricted to increasingly fragmented and degraded high elevation mixed conifer forest habitat within the Sierra Madre Occidental region of north-western Mexico. Predation of established breeding pairs has recently contributed to the ongoing decline of Thick-billed Parrot populations by removing mature birds with high reproductive value, which has associated consequences for future recruitment. We observed increasing predation events on nesting Thick-billed Parrots by bobcats Lynx rufus accompanied by kittens throughout the 2018–2019 breeding seasons, and we speculate that recent reductions in bobcat habitat have pushed them into new ranges where they are supplementing their diet with nontraditional prey items.

El género Frankliniella es de gran diversidad en los trópicosy de alta complejidad taxonómica. El grupo tritici se ha definido en este trabajo con base en los caracteres mayormente funcionales para definir el grupo de especies más restringido cercanas a las especies Frankliniella tritici y Frankliniella cubensis. Las variaciones del collar en el segmento antenal III se manifiestan en algunas especies de la serie cephalica y en algunas especies como Frankliniella standleyana y Frankliniella pineticola es evidente una modificación en forma de cono truncado. Este trabajo presenta una breve sinopsis y revisión de los grupos de especies dentro de Frankliniella incluyendo especies de las regiones del Caribe, América Central y México.
