A review of the North American species of Ammoplanellus Gussakovskij, 1931 (Hymenoptera: Ammoplanidae: Ammoplanina), with descriptions of a new subgenus, Ammoplanellus (Pseudammoplanellus), and seven new species

摘要

The genus Ammoplanellus Gussakovskij, 1931, is redescribed based on North American members. The two female North American Ammoplanellus holotypes, A. umatilla Pate, 1945 and A. xila Pate, 1945, are reviewed and their corresponding males are newly described. Seven new North American species are described: A. leucofrons, A. maculifrons, A. montanus, A. nasalus, A. owensensis, A. schlingeri and A. utahensis. A new subgenus, Ammoplanellus (Pseudammo-planellus), is proposed for A. owensensis. Relationships between the genera Ammoplanellus, Ammoplanus Giraud, 1869, and Parammoplanus Pate, 1939, are discussed. The different nesting characteristics of Ammoplanellus relative to other Ammoplanina genera are discussed. Also highlighted are the different collecting techniques for Ammoplanellus relative to ammoplanine genera.
