Wood, Thomas James, Cross, Ian & Baldock, David W., 2020, Updates to the bee fauna of Portugal with the description of three new Iberian Andrena species (Hymenoptera: Apoidea: Anthophila), Zootaxa 4790 (2), pp. 201-228 : 211

Key to Iberian Notandrena females

This key is based on a modification of the key to the nitidiuscula -group presented by Schmid-Egger & Scheuchl (1997).

1. Scutum with very dense and even punctation across the entire surface of the disc, punctures separated by much less than the diameter of a puncture, in some cases nearly touching. Underlying integument strongly shagreened and dull.............................................................................................. erythrocnemis Morawitz

- Scutum with moderate and uneven punctation, punctures separated by 1–3 puncture diameters in some cases. If occasional punctures are close to touching, then this is not consistently replicated across the whole scutum, with other punctures being separated by a clear distance. Underlying integument variable, from shagreened to shining........................... 2

2. Hind tibia and all tarsi completely orange.................................................. chrysosceles (Kirby)

- Hind tibia black, tarsi may be black or orange............................................................... 3

3. Larger species, body length 11–12 mm .................................................................... 4

- Smaller species, body length 7–10 mm .................................................................... 5

4. Pronotum laterally with a clear fold forming a keel comparable in strength to that found in the subgenus Andrena sensu stricto. Clypeus densely punctured, underlying surface smooth but not shiny. Hairs surrounding pygidial plate golden orange......................................................................................... langadensis Warncke

- Pronotum laterally with a very weak keel, almost absent, therefore appearing predominantly rounded. Clypeus densely punctured, underlying surface weakly shining, shagreened, only the front edge almost smooth. Hairs surrounding pygidial plate dark brown................................................................................. urdula Warncke

5. Tibial scopa, when viewed from the hind face, dorsally short and thick, hair length only 1–1.5 ocellar diameters, clearly shorter than the scopal hairs ventrally............................................................... pallitarsis Pérez

- Tibial scopa equally long on the dorsal and ventral sides, at least as long as two ocellar diameters...................... 6

6. Vertex clearly elongate, the hind ocelli separated from the margin of the vertex by a distance greater than the diameter of a lateral ocellus ( Figure 17 ). Genae enlarged so that the hind margin of the vertex forms a weak U-shape ( Figure 17 )............................................................................................ foeniculae spec. nov.

- Vertex not elongate, the hind ocelli separated from the margin of the vertex by a distance clearly less than the diameter of a lateral ocellus ( Figures 19 and 21 ). Hind margin of the vertex in comparison almost straight.......................... 7

7. Central line in the front half of the scutum only weakly impressed ( Figure 20 ). Scutellum more densely punctured ( Figure 20 ). Hind basitarsi orange................................................................... fulvicornis Schenck

- Central line in the front half of the scutum strongly impressed ( Figure 22 ). Scutellum less densely punctate, particularly around the central line ( Figure 22 ). Hind basitarsi dark.............................................. nitidiuscula Schenck
