Overview
Taken from: R. M. Bohart and L. S. Kimsey. 1982. A Synopsis of the Chrysididae in America North of Mexico.


Trichrysis (Caenochrysis) tridens (Lepeletier)
(Figs. 326, 332, 340, 341, 343)

Pyria tridens Lepeletier 1825:495. Holotype female, “I’ Amerique septentrionale” (Serville Coll., lost?).
Chrysis truncata Guerin 1842:146. Syntype male and female, “I’ Amerique du Nord, a Georgestown”. (Invrea Coll., Genoa).
Chrysis mexicana Guerin 1842:147. Holotype female, Tampico, (Invrea Coil., Genoa).
Chrysis tridentata Dahlbom 1845:13. Type sex unknown, “Carolina meridional” Lund?).
Chrysis virens Cresson 1865:309. Lectotype female, “Colorado Territory” (ANSP), nec virens Christ 1791.

Discussion: As remarked under mucronata, these two species are difficult to separate. T. tridens can be distinguished by the larger size, 9.0 to 12.0 mm long, lack of purple spots on T-II and III and the propodeal sculpturing. This species also tends to have a more northern distribution.

Host: Sphecidae: Trypargilum politum (Say) (Johnson 1974).

Material examined: 190 males, 786 females including types of truncata, olivieri, mexicana and virens.

Distribution: throughout eastern North America, as far north as Quebec, west to Arizona and Nevada; in Middle America as far south as Costa Rica. Nearctic collection dates are April through August.



Trichrysis (Caenochrysis) Kimsey and Bohart
Caenochrysis Kimsey and Bohart 1981:76. Subgenerotype: Pyria tridens Lepeletier 1825, original designation.
Diagnosis: T-III apex tridentate to medially pointed, discoidal cell complete, paramere with definitive telomere.
Discussion: Five species are known in the Nearctic Subregion. Many others are neotropical.
