“…The long and thin sensilla placodea found in L. suturalis are similar to those found in other melolonthine as Maladera orientalis Motschulsky, 1857 (Sericini; Shao et al, 2019), but are slightly different from those found in other melolonthine as in Macrodactylus mexicanus Burmeister, 1855 and M. nigripes Burmeister, 1887 (Macrodactylini; Martínez-Bonilla et al, 2015;Romero-López et al, 2017). The s. placodea of Macrodactylus is wider and have a more concave surface than in L. suturalis.…”

“…Similar to other melolonthid species of scarab beetles (Allsopp, 1990; Handique et al, 2017; Romero‐López et al, 2010, 2004, 2017, 2013; Romero‐López & Morón, 2013; Tanaka et al, 2006), P. flavescens adult males have longer lamellar club segments than females. Nine different types of sensilla were identified on the antenna without sex‐specific sensillar type.…”

“…The occurrence of sensilla chaetica on the scape, pedicel and funicle is widespread in Scarabaeidae (e.g., Ågren, 1985;Allsopp, 1990;Handique et al, 2017;Kim & Leal, 2000;Mutis et al, 2014;Renou, Tauban, & Morin, 1998;Shao et al, 2019;Zauli et al, 2016). ST that occur on the edges of all lamellae in P. flavescens, as well as sensilla chaetica that are morphologically similar to ST in appearance, are considered to be involved in mechanoreception in many other scarab beetles (Ågren, 1985;Handique et al, 2017;Mutis et al, 2014;Ochieng et al, 2002;Romero-L opez et al, 2010Romero-L opez et al, , 2004Romero-L opez et al, , 2017Romero-L opez & Mor on, 2013;Shao et al, 2019;Tanaka et al, 2006). They may not have a role in the proprioception of the antennal position, and movement and regulation of body position (Keil & Steinbrecht, 1984) as previously proposed in scarabs (Mutis et al, 2014;Ochieng et al, 2002;Zauli et al, 2016).…”

“…SP are numerously present on the distal surface of the third lamella in Rutelinae (Ågren, 1985; Bohacz et al, 2020). The outer surfaces of antennal club of some species in Melolonthinae, however, are smooth, and bear only hair‐shaped sensilla housing mechanoreceptors (Bohacz et al, 2020; Romero‐López et al, 2017, 2013; Yi et al, 2019). Previous single sensillum recordings demonstrated that SP housing two olfactory receptor neurons responded to sex pheromones (Kim & Leal, 2000; Larsson, Leal, & Hansson, 1999; Leal & Mochizuki, 1993; Nikonov & Leal, 2002; Nikonov, Peng, Tsurupa, & Leal, 2002; Wojtasek, Hansson, & Leal, 1998) and plant volatiles (Bengtsson et al, 2009; Bengtsson et al, 2011; Hansson et al, 1999; Larsson, Leal, & Hansson, 2001; Nikonov et al, 2001; Renou et al, 1998; Stensmyr, Larsson, Bice, & Hansson, 2001).…”

“…The length of antennal segments was measured. Classification of sensilla types was based on the previously reported morphological characters of antennal sensilla of Melolonthinae (Allsopp, 1990; Handique, Bhattacharyya, Baruah, & Boruah, 2017; Romero‐López et al, 2010, 2004; Romero‐López et al, 2010; Romero‐López, Benítez‐Herrera, Martínez‐Bonilla, Yanes‐Gómez, & Aragón‐Sánchez, 2017; Romero‐López, Carrillo‐Ruiz, & Moron, 2013; Tanaka, Yukuhiro, & Wakamura, 2006; Yi et al, 2019). The numbers of different types of sensilla were counted.…”

Morphology, microstructure, and distribution of antennal sensilla were compared between female and male Pseudosymmachia flavescens (Brenske) (Coleoptera: Scarabaeidae: Melolonthinae). Lamellate antennae of P. flavescens were shown to have typical scape, pedicel, and flagellum segments. The flagellum consists of a four‐segmented funicle and a three‐segmented club. The lengths of their pedicel and funicle were found to be similar in females and males. Distinct sexual differences were observed in the length of lamellar segments. Nine types/subtypes of sensilla were identified on the antennae of both sexes, including Böhm sensilla, sensilla trichodea, sensilla basiconica (SB), and two subtypes for sensilla chaetica, sensilla coeloconica, and sensilla placodea each. Olfactory sensilla (e.g., SB and placodea) are mainly located on three lamellar segments of the antennal club. Variation was also seen in abundance of various types of antennal sensilla, with males possessing significantly more sensilla than females. Sensilla placodea were the most abundant, and their number in males was twice of that in females, showing a clear sexual dimorphism. The difference in the distribution of sensilla placodea might reflect their roles in sexual chemical communication.

Comparative morphology of antennal surface structures in pleurostict scarab beetles (Coleoptera)

The diverse pleurostict (phytophagous) scarab beetles with characteristically clubbed antennae exhibit striking morphological variation and a variety of different antennal sensilla. Here we compare the morphology of the antennal surface between major pleurostict lineages, including Cetoniinae, Dynastinae, Melolonthinae, Rutelinae, and a few outgroups, including Scarabaeinae and Hybosoridae. We identified various types of antennal sensilla morphologically and searched for phylogenetic patterns of sensilla within the Scarabaeidae. Sensilla were examined using SEM micrographs of 36 species and the occurrence of the different types of antennal sensilla was studied for each species. We observed a high diversity of sensilla, including multiple transitional forms. There were also a number of other interesting structures on the antennal surface with adaptive value, such as elongate elevations, serial bags, and fields of setae. Our results confirm earlier findings that within pleurostict scarabs there has occurred a clear differentiation of sensilla composition and patterns.
