“…Indeed, this evolutionary scenario may be widespread, and explain the pertinent, although not ubiquitous, evolution of pollination syndromes in floral signaling. However, it may be premature to exclude the possibility of (micro) coevolution in highly specialized, mutualistic pollination systems, such as those that have evolved in some Dynastine scarabs and arum lilies (Gottsberger and Silberbauer‐Gottsberger 1991; Maia and Schlindwein 2006; Maia et al 2010). In such close relationships, the floral scents of plants and the olfactory preferences of scarabs may have coevolved, allowing highly specific communication between the plants and their pollinators (Maia 2011).…”

“…Floral food rewards for these scarab beetles are diverse and include sterile staminate or staminode tissue (Prance 1976, 1980, Young 1986, Maia et al 2010, Maldonado et al 2015), carpellary appendages (Prance and Arias 1975, Hirthe and Porembski 2003), stamens (Dieringer and Espinosa 1994, Hirthe and Porembski 2003, Costa et al 2017), petal tissue (Gibbs et al 1977, Gottsberger 1989, Dieringer and Espinosa 1994, Dieringer et al 1999, Voeks 1992), specialized adaxial food tissue of bracts (Beach 1982), and pollen (Rickson et al 1990). Cyclocephala amazona was observed consuming epidermal trichomes from the stalk of Bactris gasipaes Kunth (Arecaceae) inflorescences before feeding on pollen (Rickson et al 1990).…”

“…Detailed studies on Dieffenbachia Schott (Araceae) indicate that among a group of cyclocephaline floral visitors, some species are relatively more effective pollinators (Young 1988a). Seasonal abundance of cyclocephalines at a specific locality, along with floral phenology, may also determine which species are primary or secondary pollinators (Maia et al 2010, Costa et al 2017). …”

The cyclocephaline scarabs (Scarabaeidae: Dynastinae: Cyclocephalini) are a speciose tribe of beetles that include species that are ecologically and economically important as pollinators and pests of agriculture and turf. We provide an overview and synopsis of the 14 genera of Cyclocephalini that includes information on: 1) the taxonomic and nomenclatural history of the group; 2) diagnosis and identification of immature life-stages; 3) economic importance in agroecosystems; 4) natural enemies of these beetles; 5) use as food by humans; 6) the importance of adults as pollination mutualists; 7) fossil cyclocephalines and the evolution of the group; 8) generic-level identification of adults. We provide an expanded identification key to genera of world Cyclocephalini and diagnoses for each genus. Character illustrations and generic-level distribution maps are provided along with discussions on the relationships of the tribe’s genera.

“…This also actively released resin in Philodendron is not a floral reward nor is it involved in the attraction of pollinators, which are cyclocephaline beetles of the family Scarabaeidae (Gottsberger & Amaral 1984;Gottsberger 1986;Gibernau et al 1999;Gibernau & Barabé 2002;Gottsberger & SilberbauerGottsberger 2006;Maia et al 2010;Gottsberger et al 2013). However, it makes part of the fine-tuned pollination mechanism.…”

Floral resins of Philodendron adamantinum (Araceae): secretion, release and synchrony with pollinators

Philodendron is the only genus of Araceae in which resin release occurs in the inflorescence. The resinous secretion adheres to the smooth body surface of the pollinating scarab beetles and allows attachment of pollen grains, making its transport possible. In order to understand the process of resin synthesis and release to the external environment, we used structural, ultrastructural and histochemical analyses at different stages of development of the inflorescences of Philodendron adamantinum. Two types of secretory canals were observed in the spathe: small caliber canals near the abaxial face, and larger caliber canals in the adaxial region. Only the latter canals release secretion into the external environment. The secretory epithelium in these canals is formed by a layer of cuneiform cells, and exhibits secretory activity throughout the development of the spathe. Resin exudation is a peculiar characteristic of these canals and appears to result from pressure exerted by the secretory epithelium and by structural modifications in the wall of cells adjacent to the epidermis, which allow the formation of a separation zone whereby the resin is released. The observed synchrony between anther dehiscence and resin exudation of P. adamantinum enhances the role of this secretion in the pollination process.
