Seladonia butea ( Warncke, 1975) , nomen dubium

Halictus buteus Warncke 1975: 119 , ♀. Holotype: 1♀, Turkey, Sile, 5.VIII.1968, leg. K. Warncke (OOLM).

Comments. The holotype of Halictus buteus is a female of the S. smaragdula complex described from Sile, northwestern Turkey. Males of S. orientana and S. submediterranea occur in the same area and thus they were initially thought as good candidates for an association with this species. In fact, the males identified by Warncke as S. butea from some localities in Greece and Turkey actually belong to either S. orientana or S. submediterranea . However, as the female holotype does not bear specific characters and because no males were collected in the same locality with the type, we decided to recognize S. butea as a "nomen dubium" until further studies clarify this issue. The collection of more material from Turkey, including males from the type locality, is needed.
