Overview |
Taken from:
R. M. Bohart and L. S. Kimsey. 1982. A Synopsis of the Chrysididae in America North of Mexico.
Chrysis meta Aaron
Aaron 1885:234. Lectotype male, Montana (ANSP).
Discussion: In addition to the rather general distribution of coppery as an overlay on the basic light green of the body, has short, moderately sharp and rather even length teeth on T-III, much as in equidens. However, S-III is mostly green and coppery, and T-II posteriorly has the punctures more sparse and reflectivity greater than in equidens. Furthermore, the pit row of meta is unusually shallow, much as in provancheri. There are some similarities between meta and dorsalis, particularly the shape of the teeth on T-III. Also, male genitalia of the two species are nearly identical (fig. 231). The coppery color of meta, as well as the shinier T-II and more extensively punctate scapal basin will separate the species.
Material examined: 27 males including type, 41 females.
Distribution: Alberta, Saskatchewan, Montana, Wyoming, western Utah, Colorado, South Dakota, Nebraska, Michigan, New York, Maine. All records are east of the Great Basin and except for the last three are west of the 100th meridian.
Species group of dorsalis Aaron
Diagnosis: Male F-I longer than F-III and about 1.5-2.0 times as long as broad, female F-I 2.0-2.5 times; subantennal distance a little more or less than 1.0 MOD, shorter than malar space which is 1.5- 2.0 MOD, transverse frontal carina absent or rarely indicated (montana female); in which case eye height equals LID; genal carina separated from eye; midocellus not depressed or lidded; mesopleuron and metanotum rather simple; T-II with a weak and ill-defined median longitudinal ridge; T-III distally with a simple edge and four teeth, laterally a little irregular but essentially straight.
Included species: allectoris Bohart, dorsalis Aaron, equidens Viereck, knowltoni Bohart, Aaron, montana Aaron, paradisica Bohart, pompella Bohart, provancheri Schulz, and scitula Cresson.
Discussion: External characters for species separation are meager in some cases. However, male genitalia, particularly the parameres, are usually definitive (figs. 230-239). Two essential characteristics of these relatively small species are the absence of a definite frontal carina and a moderately long male F-I. The coppery to red coloration in three of the species is unusual among American Chrysis.
Hosts: probably ground nesting bees or wasps (see comments under dorsalis).
