Overview |
Taken from:
R. M. Bohart and L. S. Kimsey. 1982. A Synopsis of the Chrysididae in America North of Mexico.
Chrysis intricata Brulle
(Figs. 292, 306, 312)
Chrysis intricata Brulle 1846:25. Syntype female, French Guiana (lost).
Chrysis smidti Dahlbom 1854:317. Holotype female, America meridionali (Lund).
Chrysis cognata Gribodo 1879:328. Holotype female, sed sine dubio America (Brussels).
Chrysis proxima Cameron 1888:465. Holotype female, Panama (BMNH).
Chrysis schulthessi Mocsary 1889:572. Lectotype male (herein designated); Cuernavaca, Mexico (Vienna).
Chrysis aenescens Mocsary 1889:577. Holotype female, Cayenne (Geneva).
Chrysis aperta Buysson 1898 (1897):559. Holotype male, Vera Cruz (Paris).
Discussion: Diagnostic characteristics of intricata are: mesopleuron with two polished knobs, propodeal tooth lobate, T-III area beyond pit row not notched or depressed between medial teeth, teeth with apical tufts of setae, male F-I somewhat less than twice as long as broad and malar space longer than subantennal distance. Although similar to brooksi, intricata can be distinguished by the length of the malar space and the black spots on S-II; in males these spots are contiguous and form a wide indistinct edged band, in females the spots are also contiguous forming a single narrow spot in the middle of the sternum (fig. 292). The male genitalia (figs. 306, 312) are similar to smaragdula, with a long slender apical lobe on the paramere.
Material examined: 16 males, 74 females (including all types except intricata and smidti).
Distribution: This is primarily a neotropical species found as far north as southern Texas and south to Argentina. Records are from TEXAS: Cameron Co. (Brownsville), Hidalgo Co.; MORELOS, VERACRUZ, CHIAPAS, CHIHUAHUA, SINALOA, YUCATAN, SAN LUIS POTOSI, HIDALGO, GUERRERO: Nicaragua; Honduras;
Costa Rica; Panama; Columbia; Ecuador; Venezuela; Trinidad; French Guiana; Brazil: PARA, AMAZONAS, MATO GROSSO, SANTA CATARINA, SAO PAULO, PARAIBA; Bolivia; Uruguay; Paraguay; Argentina. Collection dates are March through August in Texas and Mexico.
Species group of Chrysis smaragdula Fabricius
Diagnosis: Male F-I variable, sometimes shorter than F-II or F-III, sometimes longer than either, 1.0-2.0 times as long as broad, female F-I 2.0-2.5 times as long as broad; subantennal distance 1.0- 2.5 MOD, often shorter than malar space which is 0.5 (tularensis) to 2.5 (praestans) MOD; transverse frontal carina completeto near eye, partial, or absent, not curved in below, usually without backward branches; midocellus surmounted by a thin eyelidlike fold; genal carina separated from eye by at least a narrow pitted area; mesopleuron sometimes dentate, metanotum simple; T-II sometimes with a partial and polished median longitudinal ridge, posterolateral corner 90 degrees or acute; T-III single or double edged, six toothed, lateral edge straight to moderately convex; male genitalia fairly uniform, paramere usually tapering abruptly to slender apical lobe.
Included species: archboldi Kimsey, arizonica Bohart, bequaerti Bohart, brooksi Kimsey, Cresson, inaequidens Dahlbom, intricata Brulle oraria Bohart, praestans Buysson, serrata Taylor, smaragdula Fabricius, tularensis Bohart, and wasbaueri Bohart.
Discussion: Members of this group are medium to large chrysidids with 6 teeth on T-III. A combination of characters distinguish them from our other hexadentate species in the genus: midocellus lidded, frontal carina present, genal carina separated from eye, posterolateral corner of T-II a right angle or acute, no median pit in T-III row, and paramere relatively simple. C. aridula has the posterolateral angle of T-II obtusely rounded, and has a large median pit in the T-III row. C. tenuicornis has the midocellus unlidded, T-II obtuse posterolaterally, and many peculiar features. The smaragdula species group was assigned by Bodenstein (1951:725) to the subgenus Pyria, but it has been amply demonstrated that Pyria, with a greatly reduced F-I in both sexes, as well as a produced or distorted metanotum, is a distinct genus which does not occur in the New World. Bohart (1962) reviewed our hexadentate Chrysis and provided many illustrations.
Based on the three species for which data are available, the smaragdula group attacks Eumenidae: Monobia, Euodynerus, Pachodynerus, Stenodynerus, and Parancistrocerus.
