Description: M. ericetorum is rather morphologically distinct, having dark integument with complete light apical tergal hair bands (rare, entirely melanic forms are known). Additional distinctive characteristics of the female are the long, slender, and weakly dentate mandible (Fig. 13) approaching the condition observed in the subgenus Chalicodoma, the comparatively long vertex, the shape of the apical clypeal margin as well as other characteristics mentioned in the key. Unique characteristics of the male are the unmodified front tarsi, nonetheless with long posterior hair fringe and with a distinct spot on the ventral surface of the second segment (Fig. 27); the structure of sternites 5 and 6 (Figs 66, 67), and other characteristics mentioned in the key.
M. ericetorum was found to be most closely related to the flavipes species group (Fig. 1), which is corroborated by the following characteristics: a small basal inferior tooth on the lower margin of T7 is present in addition to the apicomedian spine (Fig. 38), although the latter is absent in the flavipes species group (Fig. 39), thus only in these two taxa T7 is not emarginated; the disc of S5 is densely covered with sclerotized capitate hairs like in most other Pseudomegachile, but includes some bifid hairs anteromedially (Fig. 66) as found almost only in the flavipes species group; S6 is simple as in the flavipes species group but slightly swollen on both sides thus approaching the condition of swollen lateral lobes seen in most other groups, further it comprises intermediate number and density of sclerotized capitate and spatulate hairs between the flavipes and the cyanipennis species groups (Fig. 67).
Distribution: Morocco, Algeria, Tunisia, Europe, Israel, Turkey, Iran, Central Asia, Caucasus.
Note: This widely distributed species exhibits some geographic variation in the colour of the vestiture; nevertheless, we do not recognize subspecies as no populations appears particularly divergent or isolated from the others. Dark forms (e.g. M. ericetorum melaleuca) have been found as isolated specimens within ordinary looking populations and we do not recognize a valid subspecies for them.
Pollen hosts: Probably oligolectic on Fabaceae (Westrich 1989), although according to Westrich (1989) Lamiaceae pollen is very occasionally also used (see also Gogala 2014).
Nesting biology: Nests located in existing cavities such as existing holes in soil or clay banks, or in reed stems; cells arranged linearly and made of mud; Ferton (1895) observed females gathering moist soil close to streams (see also Le Goff 2004), a behavior not observed in bees of the subgenus Chalicodoma, which add secretions to dry mud for nest construction; exterior of cells coarse and irregular, inner wall lined with a thin layer of resin; cell closed with a plug of soil; nest closure made of a layer of mud covered by a thin layer of resin, with sometimes an additional layer of mud (Ferton 1895, Westrich 1989, Praz 2017).
