Macropis ciliata Patton, 1880: 31 . (Connecticut syntype).

Syntype. Male USA: Connecticut: New Haven Co.: “New Haven” “Waterbury”, June-July, W. H. Patton (lost?) .

Notes: Males were described from individuals collected in New Haven County, Connecticut —5 from the town of New Haven collected on the flowers of northern dewberry ( Rubus flagellaris [= R. villosus ]) on 22 June, and another from the town of Waterbury collected on the flowers of gray dogwood ( Cornus racemosa [= C. paniculata ]) on 4 July (year of collection not specified in description). These syntypes are presumed lost. This species is the presumed host of Epeoloides pilosulus , is listed as threatened in Connecticut (Connecticut Department of Energy and Environmental Protection 2015b) and is currently a regional species of greatest conservation need in four eastern states in the United States: Connecticut, Massachusetts, New Jersey, and Maryland ( United States Geological Survey 2015). The historical range of this species spans Wisconsin eastward to the province of Quebec, Canada and south to Georgia (Mitchell 1960). In Connecticut, this species has historically been detected in low numbers; however, in recent bee surveys spanning the years 2005–2017 it has been detected in seven locations in New London and Hartford Counties (n = 15).
