| Abstract: | A new specimen of the rare fossil bee Thaumastobombus andreniformis Engel 2001 (Apidae: Apinae: Electrapini) is reported and figured from middle Eocene (Lutetian) Baltic amber. The new specimen, a female of the worker caste, agrees in every respect with the holotype except some morphometric differences. These minor size differences are likely related to the degree of sociality of T andreniformis. |
