“…Within Elateridae, the sensilla chaetica C2 of Agriotes spp. are identical to the sensilla named as trichodea T1 in Agriotes obscurus, Tetrigus lewisi, and Elater ferrugineus [26,31,32], trichodea in Limonius aeruginosus [28], trichodea type III in Melanotus villosus [29], and chaetica C2 in Drilini [33]. Further, these sensilla are morphologically similar to the sensilla described on the antennal flagellum of various other beetle lineages, e.g., sensilla chaetica C2 of Lampyris noctiluca Linnaeus, 1767 (Lampyridae) [42], sensilla trichodea of Monochamus spp.…”

“…The clusters of these sensilla in ventral sensillar fields suggest that they play an important role in an olfactory search for food plants during the flight. They were also identified in other Elateridae [26][27][28][29][30][31][32][33]. Multiporous sensilla B3 and B4 are similar to sensilla B1 and B2 and most probably have the same olfactory function.…”

“…Sensilla chaetica of subtypes C1 and C2 are present in all Coleoptera. The sensilla C1 were correctly identified as sensilla chaetica in all Elateridae so far examined in previous studies [26][27][28][29][30][31][32][33]38,39] (Table 5). As in other click-beetles [32], these sensilla are widely and evenly distributed on antennae and are more abundant in females.…”

“…was observed also in other Elateridae, i.e., Agriotes obscurus [26,27], Limonius aeruginosus (Olivier, 1790) (Dendrometrinae) [28], Melanotus villosus (Geoffroy, 1785), and M. cribricollis [29,30] (both Elaterinae: Melanotini), Tetrigus lewisi Candèze, 1873 (Agrypninae: Ludioctenini) [31], Elater ferrugineus Linnaeus, 1758 (Elaterinae: Elaterini) [32], Drilus spp., Malacogaster spp., and Selasia spp. (Agrypninae: Drilini) [33] (Table 5). The "sensilla knee-bend shaped", "sensilla hook-shaped", and "sensilla screw cap" described in Melanotus cribricollis Candèze, 1860 by Peng et al [30] are not sensillum types but only some sensilla trichodea or basiconica, which were probably distorted during the preparation of antennae for the SEM.…”

Species of the click-beetle genus Agriotes Eschscholtz are economically important crop pests distributed mainly in the Northern Hemisphere. They can inflict considerable damage on various field crops. Therefore, the detection, monitoring, and control of Agriotes include the adult trapping using species-specific sex pheromones, which is a critical component of pest research. To obtain a better understanding of the detailed antennal morphology as background information for subsequent chemical ecology research, we conducted a scanning electron microscopy study of the antennal sensilla of both sexes in 10 European Agriotes species. We identified 16 different sensilla in Agriotes, belonging to six main types: sensilla chaetica (subtypes C1 and C2), sensilla trichodea, sensilla basiconica (subtypes B1–B9), dome-shaped sensilla (subtypes D1 and D2), sensilla campaniformia, and Böhm sensilla. We discuss their possible functions and compare the sensilla of Agriotes with those of other Elateridae in order to consolidate the sensillum nomenclature in this family. Additionally, our study reveals the remarkable interspecific variability in sensillar equipment of Agriotes and identifies several characters of potential importance for future use in systematic studies. The present study provides a strong preliminary framework for subsequent research on the antennal morphology of this crop pest on a wider scale.

The habit of feeding on slime moulds (Myxomycetes) commonly present in litter or dead wood requires specific morphological adaptations of the mouthparts and sensory structures involved in the search for habitat and food. In this study, the external morphology of antenna and its sensilla were studied using scanning electron microscopy in the saproxylic beetle, Clinidium canaliculatum, Costa 1839 (Coleoptera, Rhysodidae). Their moniliform antennae consist of a scape, pedicel, and nine flagellomeres. We identified seven different types of sensilla, according to their morphological characteristics: two types of sensilla chaetica (sc1 and 2), two types of sensilla basiconica (sb1 and 2), one type of sensilla campaniformia, one type of sensilla coeloconica, and Böhm sensilla. No sexual dimorphism was found regarding antennal morphology and sensilla type and distribution, except for the sensilla coeloconica. The functional role of these sensilla was discussed in relation to their external structure and distribution, and compared with the current knowledge on coleopteran sense organs. Results are basic information for further physiological and behavioral studies to identify their role in the selection of habitat, food, mates and oviposition sites.

Phytophagous scarab beetles associated with angiosperms have characteristically enlarged lamellate antennae and exhibit a striking morphological variation of sensilla. In this study, we compared the morphology of antennal surface of 62 species Scarabaeoidea using SEM microscopy, particularly also in light of their evolution in association with angiosperms. We investigated the correlation of antennal sensilla morphology, i.e., their structure and distribution, with species diversity and lineage diversification rates. A high diversity of sensilla was observed but also multiple transitional forms, even on the same antennomere. We interpreted this as evidence for a high evolutionary plasticity. We recognized clear patterns of convergence and repeated evolution of certain types of placoid sensilla. One main tendency found in the phytophagous Pleurostict chafers was a shift from sensilla trichodea to placoid-like sensilla, apparently also enhanced by the increase of the lamellate antennal surface, either by size or number of the lamellae. This trend occurred not only in the Pleurosticts, but also in Glaphyridae, a second angiosperm-associated lineage of Scarabaeoidea. However, our results suggest no direct relation between species diversity or the rate of diversification and general sensilla morphology, i.e., the origin of placoid sensilla. This could be explained not only by species-poor lineages also possessing placoid sensilla but also by otherwise successful and species rich groups having sensilla trichodea (e.g., dung beetles). Results further reveal the need to refine current phylogenetic hypotheses by more comprehensive taxon sampling and to expand the molecular characterization of pheromones and odor binding proteins to better understand the role of chemical communication in scarab diversification.
