Chrysis longula Abeille de Perrin,1879

Description and notes

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 punctures on the base of the second tergum. These punctures are as large as those on the mesoscutum and are so close together that the individual punctures are separated by ridges.


Sparingly recorded from Devon to Kent, north to Gloucestershire, Oxfordshire and Suffolk, with an outlying old record from Aberdeenshire.

Occurs in north and central Europe (including Norway, Sweden, Finland,The Netherlands, Belgium, Luxembourg, France, Spain, Germany, Italy, Poland, Hungary).
