A small black solitary wasp about which very little is known. Identification keys are given in Yeo & Corbet (1995), Lomholdt (1984) and Richards (1980).

Identification key and general biology are given in Morgan (1984). Previously this species was misidentified as H. amoenula and is also known as H. generosa (Förster, 1853) in Kunz (1994).

There are approximately 100 species in this genus worldwide. Lomholdt (1984) states that there are only seven species in Europe, but Bitsch et al. (2001) list ten, although one of these, P. hidalgo, was only described in 1990.Three species have been recorded in Britain.

Disagreement exists regarding the definition of this name. Kunz (1994) treats this species as a variety of C. ignita. Identification keys are given in Morgan (1984). General biology is given in Morgan (1984) and Falk (1991). Compared with other species of Chrysis, this species is usually relatively large, being 10 mm or more in body length. It can be distinguished from the other large species, C. pseudobrevitarsis, in having very large… Read more

Identification keys are given in Morgan (1984). General biology is given in Morgan (1984) and Falk (1991). Compared with other species of Chrysis, this species is usually relatively large, being 10 mm or more in body length. It can be distinguished from the other large species, C. longula, in having the spurs on the middle tibiae of about equal length.
