Two new records of gynandromorphs in Xylocopa Latreille, 1802 (Hymenoptera, Apidae). Gynandromorphs are deviant morphological individuals with genetically distinct male and female tissues. Records of sex anomalies seems to be important to better understand the mechanisms regulating phenotypic expression. Herein, two new cases of gynandromorphs in carpenter bee species of Xylocopa from Brazil are described and figured: a mixed gynandromorph of the X. (Neoxylocopa) brasilianorum (Linnaeus, 1767… 
Two new cases of gynandromorphism in Xylocopinae bees (Hymenoptera: Apidae) from India
ABSTRACT Two new cases of gynandromorphs in carpenter bees are described and illustrated for the first time in Ceratina (Pithitis) binghami Cockerell and Xylocopa (Biluna) nasalis Westwood. The
The first cases of gynandromorphism in oil‑collecting bees (Hymenoptera, Apidae: Centridini, Tapinotaspidini)
Described gynandromorphs of two species oil-collecting bees: Lophopedia nigrispinis and Epicharis iheringii, both with partial bilateral phenotypic asymmetry, both of which have a female phenotype predominantly on mesosoma and metasoma.

The mixed gynandromorph, recorded from a single specimen from Paraguay, exhibits a mixture of male and female features in all tagmata.
Gynandromorphism in Xylocopinae Bees (Hymenoptera: Apidae): description of four new cases
Four new gynandromorph Xylocopinae bees from Argentina are described and illustrated; one specimen of Xylocopa splendidula Latreille and three of Ceratina rupestris Holmberg. All specimens are mosaic
A gynandromorph of Xylocopa augusti and an unusual record of X. iris from Brazil (Hymenoptera: Apidae: Xylocopini)
It is described and illustrated for the first time a mixed gynandromorph of Xylocopa augusti Lepeletier de Saint Fargeau from Buenos Aires, Argentina.
A gynandromorph of Xylocopa nigrocincta Smith (Hymenoptera: Apidae).
A mixed gynandromorph of Xylocopa (NeoxylOCopa) nigrocincta is described from a single specimen from Argentina, with the right half of its head displaying male characters and the left half displaying female characters.
Description of two new cases of gynandromorphism in Paratrigona Schwarz and Augochlora Smith (Hymenoptera: Apidae and Halictidae).
Two new records of gynandromorphism in bees are described and illustrated for Paratrigona glabella and Augochlora amphitrite and the specimen described herein is now known for a total of three species in Meliponini bees and four species inAugochlorini bees.
Register of a gynandromorph of Euglossa pleosticta Dressler (Hymenoptera, Apidae)
The bee has mostly a female phenotype, except by the right half of its head, including the presence of 11 flagellomeres, ivory markings on scape and parocular area, and by deformed male characteristics on mid and hind tibiae of right legs.
As abelhas do gênero Xylocopa Latreille (Xylocopini, Apidae) do Estado de São Paulo, Brasil

A review of deviant phenotypes in bees in relation to brood parasitism, and a gynandromorph of Megalopta genalis (Hymenoptera: Halictidae)
The first known gynandromorphic bee in the tribe Augochlorini is described, a specimen of the nocturnal bee, Megalopta genalis, which demonstrates how developmental switch mechanisms might generate novel structural traits similar to those expressed as a syndrome of brood parasitic traits.

A gynandromorph is discovered in the hyperdiverse ant genus Pheidole whose pattern of bilateral head mosaicism occurs repeatedly across a wide range of ant species and is proposed to provide new insights into the modularity and evolvability of morphological traits.
