Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
Included in this subgenus are the majority of the species of the genus and all have the eyes bare or essentially so. Most of the species are to be found in the southwestern United States, where eight of the twelve known species occur in Arizona. Several of the species are present in the midwestern United States and two of the species, Holcopasites calliopsidis (Linsley) and H. illinoiensis (Robertson), extend into the Atlantic seaboard states. Only one species (H. bohartorum Hurd and Linsley) is definitely known to occur in California, though only a few miles from the Arizona border. Four species, H. calliopsidis (Linsley), H. heliopsis (Robertson), H. pulchellus (Cresson) and H. stevensi Crawford, range into the north-central United States (Montana and or North Dakota), and all except the first of these also occur in adjacent Canada. Only three of the species, H. calliopsis (Linsley), H. illinoiensis (Robertson) and H. pulchellus Cresson, have been found in Mexico, and of these only the first and last mentioned have been found appreciably south of the border into central or southern Mexico (Zacatecas and Vera Cruz). All three of these are the most wide-ranging species in the genus. ~There are two groups of species evident within the genus on the basis of the arrangement and extent of the pale pubescence on the metasomal terga. In one of the groups, the Spotted Species Group, this pubescence is arranged in the form of discrete spots basally on the metasomal terga which in one species (H. bohartorum Hurd and Linsley) coalesce to form a pair of bilobed bands on each segment. The other group of species, termed the Banded Species Group, has the pale pubescence arranged in the form of basal bands, laterally on the metasomal terga, and in one species (H. bigibbosus Hurd and Linsley) these bands coalesce medially to form a single transverse band on two or more terga.
