Taken from:
R. M. Bohart and L. S. Kimsey. 1982. A Synopsis of the Chrysididae in America North of Mexico.
Chrysis florissanticola Rohwer
(Figs. 174, 250, 251)
Chrysis florissanticola Rohwer 1909:88. Holotype male, Florissant, Colorado (USNM).
Chrysis florissantensis Rohwer of Bohart 1962:363, in error.
Discussion: This species seems closest to coloradica but the male flagellum is simple, and T-II is shinier. Further, the pit row is much weaker and may be almost obsolescent (fig. 174). The male lower frons is densely silvery but its least width is slightly more than in coloradica. The greenish color predominates in florissanticola and occasional specimens have a coppery luster. On the other hand, coloradica material is usually deep blue with only a little greenish. Modal body length is 6-7 mm. Male genitalia (fig. 250) are discussed under coloradica. The strong spiculae in the midsection of the paramere are an important feature.
Host: Anthidium banningense Cockerell (Krombein 1979).
Material examined: 51 males including type, 24 females.
Distribution: Pacific Coast and Rocky Mountain states, Alberta, Yukon Territory (Whitehorse) and Alaska (Skagway). All records are from west of the 100th meridian except one from Ramsey Co., North Dakota (about 99th meridian) and north of 37° latitude. Habitats are in Canadian and Hudsonian Life Zones.
Species group of Chrysis lauta Cresson
Diagnosis: Male F-I longer than or rarely equal to (vagabunda) F-III, 1.3-2.0 times as long as broad, female F-I 1.5-2.2 times; subantennal distance 1.3-2.5 MOD and at least slightly longer than malar space which is 0.5-2.0 MOD; transverse frontal carina absent or rarely present, partial and irregular; genal carina usually almost touching eye opposite base of forecoxa (fig. 4); midocellus not lidded; mesopleuron and metanotum rather simple; T-II with a weak and usually punctate median longitudinal ridge; T-III distally with a simple edge and four rather short teeth, lateral edge nearly straight, a little angled out medially, or weakly convex.
Included species: coloradica Bohart, florissanticola Rohwer, lauta Cresson, rivalis Bohart, tripartita Aaron, vagabunda Bohart, and xerophila Bohart.
Discussion: Except for the unlidded ocelli in the lauta, group, relationships with the propria group seem rather close. Hosts are not certain for the propria group but several of the lauta group are known to attack species of the megachilid genus Anthidium.
Key to Chrysis lauta group
1. Subantennal distance and malar space each at least 2.0 MOD, transverse frontal carina with backward branches which enclose midocellus or nearly so ………….tripartita Aaron
Subantennal distance and malar space not both as much as 2.0 MOD, transverse
frontal carina quite weak or absent ……………………………………………………….2
2. Subantennal distance about 2 MOD ………………………………………lauta Cresson
Subantennal distance not more than 1.5 MOD ………………………………………..3
3. F-I 1.3-1.8 times as long as broad, T-III pit row deep with many pits confluent
(fig. 173) ………………………………………………………………..vagabunda Bohart
F-I about 2.0 times as long as broad, T-III pit row various ……………………………4
4. T-II shiny toward apex, punctures separated by nearly a puncture diameter; T-III pit
row usually shallow, pits sometimes evanescent (fig. 174) ……….florissanticola Rohwer
T-II not shiny toward apex, punctures close; T-III pit row often deep ………………...5
5. Punctation of T-III rather fine, much more so than on scutum, S-II with two large and practically contiguous black spots …………………………………………..rivalis Bohart
Punctation of T-III coarse, about as on scutum, S-II markings various …………….....6
6. Male flagellum with ventral erect hair, much of it as long as flagellomere diameters (fig. 202); female S-II with large dark basal spots or a dark basal band, terga usually deep blue ………………………………………………………………..coloradica Bohart
Male flagellum without obvious erect hair; female S-II without dark spots or only
vague discolorations, terga more green than blue ………………………..xerophila Bohart
