Figures 2 , 5

Europiella umbrina Reuter, 1909: 85 (n. sp., descr.); Schuh et al. 1995: 389 (n. syn., disc.).

Europiella similis Knight, 1969: 81 (n. sp.; syn. by Schuh et al., 1995: 389).

DIAGNOSIS: Recognized by the moderate size, elongate oval body shape, and heavily black coloration of the dorsum except usually for base of cuneus (fig. 2); vesica with a long, decurved, anterior apical spine and shorter posterior spine, a condition shared with E. stigmosa and E. consors . Distinguished from E. stigmosa by its much more extensive black coloration, including the antennae, and from E. consors by its much smaller size and more ovate body form in the males. Sexual dimorphism in E. umbrina (and E. stigmosa ) is weak, the body form in the females being nearly the same as that in the males.

REDESCRIPTION: Male: Moderate­sized, broad­bodied species, total length 2.89–2.96, width pronotum 0.96–1.04. COLORATION (fig. 2): General coloration of dorsum black with some white markings, most often at base of cuneus and sometimes at base of corium; antennal segment 1 black, segment 2 entirely black or black on basal one­third with remainder pale, coloration of segments 3 and 4 variable, usually pale; labium mostly black; most of venter black; trochanters pale; femora often heavily darkened but with some pale areas ornamented with dark spots or blotches; tibiae with pale background coloration with black spines with black bases. SURFACE AND VESTITURE: Surface and vestiture as in generic diagnosis. STRUC­ TURE: Elongate ovoid, corial margin moderately convex. GENITALIA (fig. 5): Pygophore moderately large relative to total size of abdomen; vesica similar in structure of apical spines to E. stigmosa and E. consors , anterior spine long and decurved, posterior spine shorter and weakly decurved.

Female: Coloration and structure very similar to that in males. Total length 2.73– 2.89, width pronotum 1.02–1.06.

HOSTS: Recorded from Artemisia spp. , including A. californica , A. filifolia , A. nova , and A. tridentata (Asteraceae) .

DISTRIBUTION: Widely distributed in western North America, primarily in the interior.

DISCUSSION: Knight (1968: 43) listed E. umbrina as a synonym of E. stigmosa , a taxonomic decision reflected in the catalog of Henry and Wheeler (1988). Schuh et al. (1995) treated E. umbrina as a valid species on the basis of its distinctive male genitalic structure.
