Species Notes

The syntype series (4 specimens) of M. ciliata Patton is at MCZ.

The original type material of M. longilingua from Canada [Quebec, Cap Rouge] has been lost (see Snelling and Stage 1995: 27; Sheffield and Perron 2014: 135), so a neotype (a specimen of M. ciliata from New York) was designated by Snelling and Stage (1995: 27) to fix the name to a specimen. Provancher’s (1888: 424) brief description makes it difficult to confirm the synonymy, and Snelling and Stage (1995: 27) indicated that there is no certainty that it is even a Macropis), though Provancher he described the hairs of the legs “avec poils blancs”, partially supporting the distinction between it and M. nuda (see Mitchell 1960: 526; Snelling and Stage 1995: 27; though the differences in mid and hind leg colour are restricted to the basitarsi only), but not necessarily between it and M. patellata Patton. Michener (1938a: 133) thought that Provancher’s species, likely based on description, was probably a synonym of either M. ciliata or M. patellata (as did Snelling and Stage 1995: 27). However, without having Provancher’s type material, its presence in Canada (INHS from NB) needs to be confirmed. Gibbs et al. (2022: XX) recently reported that the specimen from MB (at INHS) was a misidentified specimen of M. nuda (Provancher).

The DNA Barcode Index Number (BIN) for this species has not been assigned.



This species, like all bees of the genus Macropis, is a oligolege on oil producing flowers of the genus Lysimachia (Popov 1958; Cane et al. 1983; Michez and Patiny 2005; Dötterl and Schäffler 2006). This species is likely a host for the cleptoparasitic bee, Epeoloides pilosulus in Canada (Sheffield et al. 2004; Sheffield and Heron 2018).
