The family name Apidae has been used here in its
strict sense of Michener (2000). The included species of bees reflect very high
diversity in their biology, from solitary to highly social behaviour.
Apidae has been subdivided into three subfamilies
namely, Xylocopinae, Nomadinae and Apinae. Xylocopinae include large Carpenter
bees on one hand and, small Ceratina like bees onto another. Nomadinae
entirely consist of cleptoparasitic bees (Rozen, 1996 : Phylogeny). Rozen (2001)
published a taxonomic key to mature larvae of cleptoparasitc bees and in 2000 he
presented pupal descriptions of some cleptoparasitic bees included in Apidae.
Many belong to Apidae. Michener (2000 p.571) stated 'great diversity of the
subfamily Apinae is an invitation to those who would like to subdivide it into
several subfamilies, but it is not clear how such subdivision should be done.
More than 6,000 research references are available
for Apis mellifera alone since 1970. Thousands are concerning beekeeping
in addition to. I have estimated that around 20,000 research references related
to this Family can be isolated out of the Apoidean literature. More recent works
with regard to phylogeny of Apidae are: Roig-Alsina and Michener (1993),
Eickwort and Eickwort (1978), Silveira (1993), Rozen (1994, 1996). Biology and
immature stages of the tribe Tetrapediini (Rozen, 2002) and oocyte, eggs and
ovarioles of some long tongued bees described by Rozen (2003) are some of the
recentmost important references, one should consult.
