Two new records of Gynandromorphs in Xylocopa (Hymenoptera, Apidae s.l.)

Abstract

Abstract. 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) from São Paulo and a bilateral gynandromorph of the X. (Neoxylocopa) ordinaria Smith, 1874 from Sergipe.

The first cases of gynandromorphism in oil‑collecting bees (Hymenoptera, Apidae: Centridini, Tapinotaspidini)

“…Gynandromorphism in bees are known from more than 140 species and 36 genera belonging to all families, though most of these records belong to the longtongued bee families (Almeida et al, 2018;Prashantha et al, 2018). Within the family Megachilidae, the records of gynandromorphs are in three tribes (Anthidini, Megachilini and Osmiini), but mainly are present in the genus Megachile Latreille (Hinojosa-Díaz et al, 2012; Coelho et al, 2016).…”

A new case of gynandromorphism in Xylocopa frontalis (Olivier) (Hymenoptera: Apidae), with an updated review of records in Xylocopinae Latreille

“…Megachille Latreille) and carpenter bees (e.g. Xylocopa Latreille) (Wcislo et al 2004;Michez et al 2009;Hinojosa-Díaz et al 2012;Lucia and Gonzalez 2013;Vivallo 2015;Zama and Coelho 2017;Almeida et al 2018;Onuferko 2018;Prashantha et al 2018). Recent records have also been made in orchids bees of the genus Euglossa Latreille (Giangarelli and Sofia 2011;Hinojosa-Díaz et al 2012;Camargo and Gonçalves 2013;Suzuki et al 2014), oil-collecting bees of the tribe Centridini and Tapinotaspidini (Alvarez et al 2019), stingless bees of the genus Paratetrapedia Schwarz and sweat bees of the genus Augochlora Smith (Alvarez et al 2014).…”
