Andrena (Notandrena) trimarginata (Radoszkowski, 1886)

Halictus trimarginatus Radoszkowski, 1886: 21, ♀ [Turkmenistan, ZMHB, examined] (Figures 42A–D)

Andrena (Carandrena) zostera Warncke, 1975b: 99, ♂ [Turkey, OÖLM, examined] syn. nov.

Andrena (Carandrena) subsmaragdina Osytshnjuk, 1984: 13, ♀ ♂ [Turkmenistan, SIZK, not examined] syn. nov.

Remarks. Warncke (1967) and Gusenleitner & Schwarz (2002) indicated that the type material of A. trimarginata was present in the ZMHB, consisting of a head and mesosoma fragment only. This fragment was examined (Figure 42), and confirmed its identity as a small Notandrena species with metallic green-purple reflections. Described from Ashgabat in Turkmenistan, this fragment is sufficient to allow recognition that this material is conspecific with A. zostera . The revision of Wood & Monfared (2022) demonstrated that A. zostera was the senior synonym of A. subsmaragdina Osytshnjuk, 1984, which was considered to be the only metallic green Notandrena found in Central Asia. Andrena trimarginata therefore becomes the senior name for both taxa syn. nov.
