This complex includes Laphria sericea, L. aktis, and an undescribed eastern species similar to sericea. These flies are normally not determinable from photos. Males are separable with sharp images of terminal appendages. Females are not safely separable from photos. The undescribed species found by Stephen Bullington (unpublished PhD thesis) is also basically identical in general appearance, and the possibility exists that some images are that species. Please place undetermined members of this complex here (including all females, unless identified by dissection or in copula with male of known identification). Please only place males definitely determined to species from genitalia to the aktis, sericea, or the undescribed species pages. Thanks.
