Hemipenthes eumenes
Description 3
Almost identical to H. morioides. Both are smallish, black bee flies, often with white hairs bordering the thorax. The difference is in the discal cell: when the dark pigmentation goes past the r-m crossven, its H. morioides, but if it doesn't, it's eumenes (see comments by Joel Kits at http://bugguide.net/node/view/702073).
Taxonomy 3
Note that Ávalos-Hernández (2009) treats this as a synonym of Hemipenthes seminigra, and he says it can be "distinguished from H. morioides by the lack of aureoles in the wings and from the European specimens of H. morio by having the cell r5 narrowed at wing margin and the margin epiphallus straight in ventral view." Kits seems reluctant to adopt this treatment: http://bugguide.net/node/view/75568, and Systema Diptorum hasn't seemed to have adopted those changes either, though I'm not sure if that means they don't support the paper or if they just haven't considered it.
