A synopsis of the species of Centris subgenus Aphemisia Ayala in Colombia is presented. A total of six species were recognized: C. lilacina Cockerell, C. mocsaryi Friese, C. plumipes Smith and C. quadrimaculata Packard, including C. celadonia n. sp. and C. vallecaucensis n. sp., two new species described from the Departments of Huila and Valle del Cauca, respectively. Diagnoses, descriptions, information on geographical distribution and an identification key to all species are provided. The previously unknown male of C. plumipes is described for the first time.

Wild bees are vital for the pollination of native plants and crops, providing essential ecosystem services. Climate change is known to impact biodiversity and species distributions, but insects adapted to desert ecosystems may exhibit unique physiological, behavioral, and evolutionary responses. The desert pallid bee (), a solitary bee native to the arid southwestern United States and northern Mexico, primarily forages on yellow palo verde (), blue palo verde (), and desert ironwood ().

Background And Aims: Spatial variation in plant-pollinator interactions is a key driver of floral trait diversification. A so far overlooked qualitative aspect of this variation is the behavioural component on flowers that relates to the pollinator fit. We tested the hypothesis that variation in pollinator behaviour influences the geographical pattern of phenotypic selection across the distribution range of the oil-producing Krameria grandiflora (Krameriaceae).

Heteranthery, the presence of different types of anthers on the same flower, is a floral adaptation that aims to balance the need for pollinators to collect pollen as a food resource while ensuring sufficient pollen for pollination. We investigate the role of heteranthery in the pollination of Senna arnottiana flowers and how it is affected by the behaviour of visiting bee species, with a particular focus on the impact of the invasive bumblebee Bombus terrestris. In three populations of S.
