“…Early clades of major holometabolous insects often bore adult specializations for pollen feeding during the early Mesozoic, such as Xyelidae (Hymenoptera: Jervis & Vilhelmsen, 2000), Micropterygidae and Agathiphagidae (Lepidoptera: Kristensen, 1997), and Cupedidae (Coleoptera: Hornschemeyer et al, 2002). Although palynophagy is an ancient feeding style for holometabolous insects that extends to the Paleozoic, Coleoptera currently includes the greatest diversity of palynophagous taxa (Samuelson, 1989), an expansion commencing during the Middle and Late Jurassic (Arnol'di et al, 1977;Hunt et al, 2007). Mandibulate, palynophagous insects process pollen in many ways.…”

“…Generalist phytophagous beetles, which are herbivores on numerous different plants, such as many Chrysomelidae, are often facultative florivores, feeding on pollen and nectar or other tissues (Samuelson, 1994;Held & Potter, 2004). Other generalist chrysomelids may be restricted to petals and other flower parts, yet without great specificity possibly because of a parallel lack of profound chemical specificity of corresponding tissues.…”

In the Republic of Panama, phytophagous beetles were collected by hand and beating from superficially similar generalist blossoms of Nectandra umbrosa (Lauraceae) and Tapirira guianensis (Anacardiaceae), two phylogenetically distant Neotropical canopy trees. Beetles were sorted into three functional groups (guilds): general flower visitors, species developing in buds, and seed predators. Out of a total of 1,564 collected specimens belonging to 177 beetle species, 55 species or 31% were identifiable to specific epithet. These small-to mediumsized beetles belonged to four families: Cerambycidae, Chrysomelidae, Brentidae, and Curculionidae. A total of 723 beetles representing 121 species, and 841 beetles representing 121 species were recorded from N. umbrosa and T. guianensis, respectively. Of the beetles collected, 65 species were common to both trees, which equates to a similarity index value of 0.46 (Jaccard) or 0.34 (Sorensen). With respect to functional groups, there was no significant difference in the number of beetle species between the two tree species. Overall, beetle abundance patterns on flowers of the two trees are similar in terms of phytophagous beetle subfamily dominance. There are differences however, significantly more leaf beetles (Cryptocephalinae, Eumolpinae, Galerucinae) were collected per hour on T. guianensis than on N. umbrosa. Moreover, among beetles shared between the two tree species, Baridinae weevils showed a tendency to be more abundant on M umbrosa. Nearly three-quarters of the flower feeders (72%) were shared between the two trees. The large overlap in beetle species between the two plant species suggests that the fauna is fairly general in terms of host use. We discuss the possible significance of our results to phytophagous beetle and host plant evolution. The combined effects of large species numbers, high abundance and broad diet breadth across generalist flowers of tropical canopy trees suggests that small-to medium-sized beetles play a crucial role in maintenance of species biodiversity and forest ecosystem function.

“…It is increasingly evident that New Caledonian Arsipoda can utilize a broad range of plant associates (some as possible larval food plants) and that pollen-feeding is included in adult feeding strategies (Gomez-Zurita et al 2010;Samuelson 1989Samuelson , 1994.…”

“…It is likely that most species of New Caledonian Arsipoda will be shown to eat pollen. Mouthparts adapted for pollen uptake may show special modifications: e.g., long and dense setae on the mandible inner lobe and outer margin, the maxillary galea and lacinia, and flat areas at the base of the mandible for grinding pollen grains (Bieńkowski 2010;Samuelson 1994). Mouthparts of A. shirleyae ( Fig.…”

“…7A-B) have long setae on the maxillae, but not on the mandibles, which have an inner lobe covered by short and dense setae that may be used for pollen feeding; this species also lacks mandibular grinding areas and that may explain the intact pollen grains in the gut. The mode of pollen digestion by these beetles remains unknown (Bieńkowski 2010;Samuelson 1994).…”

A taxonomic revision of the New Caledonian species of Arsipoda Erichson, 1842 is provided. This group includes 21 species, of which 14 are new to science: Arsipoda atra sp. nov., A. communis sp. nov., A. doboszi sp. nov., A. elongata sp. nov., A. gomezzuritai sp. nov., A. gressitti sp. nov., A. longifrons sp. nov., A. montana sp. nov., A. paniensis sp. nov., A. povilaensis sp. nov., A. punctata sp. nov., A. rutai sp. nov., A. transversa sp. nov. and A. wanati sp. nov. A key for the identification, with figures of habitus, main diagnostic characters, and genitalia is supplied. The range of host plants for these species is extraordinarily broad, and a significant number of them feed on pollen. Crepicnema Scherer, 1969, close to Arsipoda, is also investigated and maintained as a separate genus, and the following synonymies and combination are proposed: Crepicnema parvula (Jacoby, 1885) comb. nov. = Chaetocnema tenimberensis Jacoby, 1894 syn. nov., = Arsipoda salomonensis Bryant, 1941 syn. nov. The phylogenetic analysis, including also A. bifrons Erichson, 1842 and Crepicnema, confirms some trends in distribution patterns of the endemic New Caledonian fauna, and highlights the necessity of further studies to clarify the relationships between Arsipoda and related genera.
