“…It also appears that such male cephalic polymorphism often occurs in communal species (Maeta 2000;Danforth et al 2019). In the Japanese species of the sexstrigatus group, L. (H.) ohei has indeed been reported as a communal species (Sakagami et al 1966). The other Japanese species with male cephalic polymorphism may also be communal.…”

“…The members of sexstrigatus group except for Lasioglossum (Hemihalictus) frigidum Sakagami & Ebmer, 1996 display male cephalic polymorphism (Sakagami et al 1966;Ebmer et al 1994;Sakagami & Ebmer 1996;. This polymorphism is caused by the allometric development of the head (Sakagami et al 1966). The presence of a genal process is characteristic of the sexstrigatus group, but is not known from the japonicum group (Sakagami et al 1966;Ebmer et al 1994;Sakagami & Tadauchi 1995;.…”

I propose a redefinition of the sexstrigatus group of Lasioglossum (Hemihalictus) Cockerell, 1897, including a phylogenetic analysis. This group is characterised by a combination of the following 12 characteristics: male antenna short, not attaining to metasoma, male labrum with distal process and well-developed basal elevation, male head with genal process as variation, female mesepisternum reticulate-punctate on lower area, mesepisternum without tubercle in both sexes, female metasomal terga with distinct fimbriae on posterior margin, male S8 with well-developed median process, gonobase ventral arm of male genitalia connected with each other at upper ends, gonocoxite of male genitalia smooth, gonostylus of male genitalia small and simple, bud-like, and the ventral retrorse lobe of male genitalia not attaining to gonobase. The Japanese species of the sexstrigatus group are revised. Thirteen species in total are recognised, including three new species: Lasioglossum (Hemihalictus) ikudomei sp. nov., L. (H.) spectrum sp. nov., and L. (H.) subsimplicior sp. nov. Lasioglossum (Hemihalictus) perplexans (Cockerell, 1925) is synonymised under L. (H.) kiautschouense (Strand, 1910). A key to the Japanese species is provided. Bionomical data, such as flight and flower records or habitat, are reported for some species. The distributions of all species are mapped. DNA sequences including a part of the barcode region are given for L. (H.) kiautschouense, L. (H.) ohei Hirashima & Sakagami, 1966, L. (H.) speculinum (Cockerell, 1925), L. (H. ) spectrum sp. nov., L. (H. ) subsimplicior sp. nov., and L. (H. ) taeniolellum (Vachal, 1903).

Motor innervation and proprioceptors of the mouthparts in the worker honey bee, Apis mellifera. I. Mandibular nerve

The innervation of the mandibular nerve of the worker honey bee was investigated primarily with methylene blue vital staining. Results on the motor innervation were compared with those of earlier work, yielding some corrections and new findings. The nerve to the mandibular abductor muscle not only carries motor fibers but also supplies sensory branches to the head integument and to the presumptive proprioceptors which probably monitor movements of the proboscis. A small neural mass which is equipped with two systems for proprioception is situated at the point where the mandibular nerve divides into its major branches. One system is composed of receptor muscles stretched between the anterior tentorial arm (AT) and the mandible and multipolar cells. The other is composed of elastic strands between AT and the apodeme of a smaller branch of the mandibular adductor and tripolar cells. The former is stretched by mandibular abduction and the latter by adduction. The two systems collectively are called the mandibular muscle receptor organ. There are two groups of receptor muscles: the outer receptor muscle, which is located outside the neural mass, and the inner receptor muscle located within. Only the latter is innervated by multipolar cells. Another, single, multipolar cell is attached to the surface of the tendon of the inner receptor muscle. A further pair of bipolar-multiterminal cells attaches to the epidermis at the extremity of the apodeme of the mandibular adductor. One originates from the mandibular nerve and the other from the labral nerve. Both presumably respond to the epidermal expansion caused by mandibular abduction.
