“…Sensilla length was measured using the Image ProPlus 4.5 program (Ravaiano et al , ). We chose to study the dorsal surface of the antennae of T. fiebrigi because, as previously reported for other bees, sensilla are present in higher numbers and are more diverse on the dorsal surface of the appendage (Ravaiano et al , ; González‐Vaquero & Galvani, ; Carvalho et al , ; Galvani et al , ). In our case, there were fewer sensilla (two types of both sensilla trichodea and sensilla placodea) on the ventral surface of the antennae than in the dorsal surface, and only one subtype of sensilla trichodea on the pedicel of all classes of individuals of T. fiebrigi (Fig.…”

The antennae of the insects have cuticular structures called sensilla that play a pivotal role in the perception of stimuli and in communication. The morphology of antennal sensilla has been characterized in eusocial bees; however, there is little information on bees of the genus Tetragonisca. Using scanning electron microscopy, 11 types of antennal sensilla were identified in Tetragonisca fiebrigi: trichodea (ST, subtypes I-VI), placodea, basiconica, coeloconica, ampullacea, and campaniformia. The largest diversity of sensilla was observed in females. The STI was the most abundant, followed by the placodea and the STII. The STI and the sensila placodea were more abundant in males than females, while the STII were more abundant in workers. Significant differences were found in the length of the different types of sensilla among the classes of individuals, with these differences being greater for the STI in males and the STV in queen; for the STII, STIII, and STIV in queen and workers; and for sensila placodea in queens, workers, and soldiers. Multivariate analysis (PCA and UPGMA) showed that the soldier subcaste was separated from the other females. This study advanced our understanding of sensilla morphology, including the number and distribution of sensilla across sexes and castes, and the sensory structures of T. fiebrigi. The results presented provide relevant information for elucidating the communication mechanisms of social insects.

“…With the goal of finding characters that allow differentiation of the new species of Lasioglossum (Dialictus), the different sensilla on the antenna of females from these taxa were examined. Sensilla variation has been found to be useful for discrimination of parasitic bees (Wcislo 1995;Galvani et al 2016). The following types of sensilla are recognized in species of Lasioglosum (Dialictus): stA, stB, stC, stD, sPa, sCoe, sAmp, Scap value and setae (Fig.…”

Lasioglossum is a large genus of halictid bees with high species diversity in morphologically rather cryptic species groups. With more than 1900 described species, the taxonomy of the genus is complex and largely unresolved in many regions. For practical reasons, systematic reviews are restricted in scope either geographically or to particular species groups. In this study we focus on the subgenus Dialictus of the genus Lasioglossum from the Yucatán Peninsula in Mexico. In previous studies we identified members of the genus as important pollinators of cash crops in the region, and genetic analyses suggested the existence of seven molecular taxonomic units (mOTU). Based on additional morphological differences, we here describe these mOTUs as novel species, Lasioglossum (Dialictus) yucatanense Landaverde-González sp. nov., L. (D.) paxtoni Landaverde-González sp. nov., L. (D.) ameshoferi Landaverde-González sp. nov., L. (D.) aureoviride Landaverde-González & Husemann sp. nov., L. (D.) paralepidii Gardner sp. nov., L. (D.) milpa Landaverde-González sp. nov. and L. (D.) nanotegula Landaverde-González & Husemann sp. nov., and provide keys and images to assist in their identification.

“…They play an important role in insect life behaviors, such as habitat selection, food searching, mating, oviposition sites, and intraspecific and interspecific recognition [ 3 , 4 , 5 , 6 ]. Previous studies have shown that the type and distribution of sensilla in antennae are related to sex [ 7 , 8 , 9 ], feeding [ 10 , 11 ], and whether they sojourned [ 12 , 13 ], which are decided at the stage of insect morphogenesis [ 14 , 15 ]. Even the types, numbers, and distribution of antennal sensilla are diverse in different castes in the same species [ 16 , 17 ].…”

Bumblebees, as pollinators, play an important role in maintaining natural and agricultural ecosystems. Antennae with sensilla of bumblebees as social insects have essential effects in foraging, nest searching, courting, and mating, and are different in species and sexes. Previous studies on the morphology of antennae and sensilla in bumblebees have been limited to a few species and a single caste. To better understand how bumblebees detect and receive the chemical signal from nectariferous plants and foraging behavior, the morphology of antennae with sensilla, including the antennal length, and type, distribution, and number of antennal sensilla in four species, Bombus atripes, Bombus breviceps, Bombus flavescens, and Bombus terrestris was compared by scanning electron microscopy (SEM) herein. The total antennal length of queens are the longest and workers are the shortest in three castes, and in four species the longest of the total antennal length among three castes all are in B. flavescens, which is significantly longer than other species (p < 0.05) and the length of the scape in queens and workers are both longer than males, significantly different in queens (p < 0.05), and not significantly different in workers (p > 0.05), and the length of flagellums in females are not always shorter than males, of which the length of flagellms in queens of B. flavescens are significantly longer than males (p < 0.05), and the length of pedicel and all flagellomeres varies among species and castes. A total of 13 major types of sensilla in total were observed, including trichodea sensilla (TS A-E), placodea sensilla (PS A-B), basiconica sensilla (BaS), coeloconica sensilla (COS A-B), chaetic sensilla (CS A-B), and Böhm sensilla (BS), of which chaetic sensilla B (CS B), only observed in females of B. atripes, was firstly reported in Apidae. Moreover, the number of all sensilla was the most in males, the least was in workers, the number of sensilla varies within castes and species. Furthermore, the morphological characteristics of antennae and the potential functions of sensilla are discussed.
