Overview |
Taken from:
R. M. Bohart and L. S. Kimsey. 1982. A Synopsis of the Chrysididae in America North of Mexico.
Chrysis derivata Buysson
(Figs. 166, 186, 263)
Chrysis derivata Buysson 1891:38. Holotype male, Quebec, Canada (Paris).
Chrysis decepta Rohwer 1909. Holotype female, Boulder, Colorado (USNM).
Discussion: This relatively abundant species is close to the much less common irwini and doubtful cases may require comparison of male genitalia (figs. 263, 265). Female derivatata are usually larger and have the thorax proportionately longer. Males have T-III markedly concave laterally.
Hosts: Ancistrocerus catskill halophilus Viereck, Euodvnerus foraminatus apopkensis (Robertson), E.f. scutellaris (Saussure), Symmorphus cristatus nevadensis (Cameron), all reared from trap stems or borings in wood by Parker and Bohart (1966) and Krombein
(1967).
Material examined 178 males including type of derivata, 286 females including type of decepta.
Distribution: Records are from practically every state in the Union except New Mexico and Arizona. It has been collected also in all the southern tier of Canadian provinces.
Species group of Chrysis pattoni Aaron
Diagnosis: Male F-I not longer than F-III, 1.0-1.5 times as long as broad, female F-I 2.0-2. 7 times; subantennal distance a little more or less than 1.0 MOD, usually shorter than malar space which is 1.0-2. 5 MOD; transverse frontal carina complete nearly to compound eye but not curved in below, no backward branches; genal carina separated from eye; midocellus not lidded; mesopleuron and metanotum rather simple; T-II sometimes with a densely micropunctate median longitudinal ridge; T-III distally with a simple edge and four teeth, laterally nearly straight or concave in males of some species; male S-VIII greatly narrowed distally, least so in karri, most in lucifera.
Included species: amala Rohwer, barri Bohart, derivata Buysson, irwini Bohart, lucifera Bohart, pattoni Aaron, and snowi Viereck.
Discussion: Males of the pattoni group are rather easily distinguished on the basis of male genitalia (figs. 257, 264). Also, they have F-I in various stages of reduction. Females of some species are difficult to separate. Several species have been reared from eumenid hosts in twigs or other wood cavities.
