Description of the male of Macrocamptoptera setata Triapitsyn, 2012 (Hymenoptera: Mymaridae) from California, U.S.A.

Abstract

The Holarctic fairyfl y genus Macrocamptoptera Girault, 1910 (Hymenoptera: Mymaridae) was revised by Triapitsyn (2012) and Triapitsyn et al. (2020). Among its two known Nearctic species, the male of the rarely collected, western Nearctic M. setata Triapitsyn, 2012 was previously unknown. Recently, I recognized three male specimens of this species among material from Mendocino County in northern California, U.S.A.; these are described and illustrated herein. Terminology used follows Triapitsyn (2012) and Triapitsyn et al. (2020). An abbreviation used is: F = fl agellomere of the male antenna. The following acronym designates the depository of specimens: UCRC—Entomology Research Museum, University of California, Riverside, California, U.S.A.
