Andrena tiaretta- group: specimens from Egypt, Iran and without provenance

There are two specimens, one from Egypt and one from Iran. Both are definitively members of the A. tiaretta -group.

The female of Egypt (see comments chapter ‘provenances ’) has no clear provenance and show morphological characters between A. cyrenaica nov.sp. and A. orientalis nov.sp. Without knowing exactly the provenance and testing more specimens (especially males) a further classification (grouping to A. cyrenaica nov.sp. or A. orientalis nov.sp.) is not possible (see also the comments of the morphometric analysis). The same is true in the case of the female specimen which was collected in North Iran. There are some indications of an affinity to A. orientalis nov.sp., but also some decisive differences occur: most parts of the clypeus are chagreened. T6 is characterised by yellowish-reddish hairs in contrast to A. tiaretta s.str., A. cyrenaica nov.sp. and A. orientalis nov.sp. Without testing more specimens (especially males) a further classification is not possible. The provenance of one female specimen (OLML 133, paratype) is not known. The morphological analysis indicates a relationship to A. orientalis nov.sp. or A. cyrenaica nov.sp., but not with A. tiaretta s.str. (see morphometric results of OLML 133).
