I am working with colour patterns of a flower pollinated by Centris sp.. But I have difficulty in find their photorreceptor sensibilities to run the colour vision models. Thanks!
Great question. Hopefully, you will not find and there is no data exist. you must have to rely on honeybee or Bumblebee. In general, Hymenopteran visual systems phylogenetically conserved (see Brioscoe & Chittka 2001, Ann rev Entomology) and many Chittka et al paper . I think this will help you further what you want to use. I use Stavenga template generally. see below Casper comment for detail

Dear Shresta and Kooi,
Thank you for your kind answer. I don´t have the spectral sensitivity maxima but I will search for something. If I couldn´t find it, I will keep using Apis/Bombus data with Brioscoe & Chittka 2001 citation.
All the best!
Hello Dear
The bumblebee Bombus impatiens is increasingly used as a model in comparative studies of colour vision, or in behavioural studies relying on perceptual discrimination of colour. However, full spectral sensitivity data on the photoreceptor inputs underlying colour vision are not available for B. impatiens. Since most known bee species are trichromatic, with photoreceptor spectral sensitivity peaks in the UV, blue and green regions of the spectrum, data from a related species, where spectral sensitivity measurements have been made, are often applied to B impatiens. Nevertheless, species differences in spectral tuning of equivalent photoreceptor classes may result in peaks that differ by several nm, which may have small but significant effects on colour discrimination ability. We therefore used intracellular recording to measure photoreceptor spectral sensitivity in B. impatiens. Spectral peaks were estimated at 347, 424 and 539 nm for UV, blue and green receptors, respectively, suggesting that this species is a UV-blue-green trichromat. Photoreceptor spectral sensitivity peaks are similar to previous measurements from Bombus terrestris, although there is a significant difference in the peak sensitivity of the blue receptor, which is shifted in the short wave direction by 12–13 nm in B. impatiens compared to B. terrestris.

Thank you guys! I will consider both answers on the next time I run a colour vision model!
Cheers!
