Ancistrocerus waldenii waldenii : Krombein 1979: 1505; Buck et al. 2008: 113. Examined material : GREENLAND: Kangerlussuaq/Sdr Strømfjord (67°00′ N 50°41′ W), 2 Aug. 1992 (ZMUC, Leg. J, Böcher)—4 ♀, 4 ♂; Itilleq, eastern end (66°33′ N, 52°26′ W), 22–23 Jul. 2003 (ZMUC, Leg. Kissavik Expedition ZMUC)—7 ♀, 2 ♂; Søndre Isortoq, Nuk (65°28′ N, 52°12′ W), 13–14 Jul. 2003 (ZMUC Leg. Kissavik Expedition ZMUC)—1 ♀; Kangerlussuatsiaq/Evighedsfjord, Taterat (66°00′ N, 52°33′ W), 19 Jul. 2003 (ZMUC Leg.

In the USA in AZ, CA, CO, IL, MI, MT, NM, SD, VA and WY. Greenland (new record). Subspecies A. w. excavatus Bequaert 1944 and A. w. flavidulus Bequaert 1944 from BC and CA to MT, WY, CO, AZ (Krombein 1979). All specimens were identified as Ancistrocerus waldenii (Viereck 1906) (Fig. 1). This species is most similar to A. albophalerathus (de Saussure 1855) and an undescribed Ancistrocerus sp. A (Buck et al. 2008). Males of A. waldenii are separated from similar species in North America by the deeply emarginated clypeal margin. Females can be distinguished from similar species by the completely black scape and by the presence of a pale apical spot on tergum 6 (Buck et al. 2008). Overall, colour patterns are rather variable (Buck et al. 2008) and the Greenland specimens tend to have reduced pale markings compared to North American specimens. A detailed description of the species is available in Buck et al. (2008). Ancistrocerus waldenii was seen to be abundant in the area ...
