Protosmia (Nanosmia) devia Tkalcu, 1978

1978 Protosmia (Rhodosmia) devia Tkalcu, Casopis Slezskeho Muzea Opava (A), 27: 158. Type material: Holotype f, “Kashmir: Gulmarg” [India], BMNH (London).

Distribution-Europe: CH, E, F, I, I(Si).

Identification-Keys, Descriptions: Amiet et al. (2004); Benoist (1929a); Ducke (1900); Griswold and Parker (1987: 55); Zanden (1986: 67, 1994b: 1116).

Nesting biology: Unknown.

Flower preferences: Polylectic with a preference for small-flowered Lamiaceae (e.g. Teucrium); additional pollen sources include Helianthemum (Cistaceae) (Amiet et al., 2004; Müller, 1996b; A. Müller, unpublished, based on 5 pollen samples from 5 different localities). Pollen-collecting females climb the filaments of the stamina of Teucrium montanum, the flowers of which lack an upper lip, until the head is beyond the uppermost anthers; by rapidly seesawing the underside of the abdomen against the anthers, the bees then directly pick up the pollen into the abdominal scopa (Müller, 1996b; Müller et al., 1997).
