Plagiognathus fulvaceus
Knight, 1964: 144
(n.
sp.).
Microphylellus symphoricarpi
Knight, 1968: 30
(n. sp.). NEW SYNONYMY.
DIAGNOSIS: Recognized by
moderately large
size, generally dull
reddish coloration
(including all appendages [fig. 8], although antennal segment 1 sometimes partially to completely dark and segment 2 often dark at base), and
vestiture of dorsum reclining, golden,
shining, and somewhat shaggy. Similar to
aquilinus
(fig. 6) and
mexicanus
(fig. 10) in the red coloration, but those species with black setae on the dorsum and
mexicanus
with all antennal segments black. Also potentially confused with
concoloris
and
lonicerae
,
but those species larger and not so strongly reddish and with dark setae on pronotum. Vesica (fig. 24) distinctive, similar in form to that of
albifacies
(fig. 20), long, relatively slender, broadly curving, and with relatively short, slender, erect, weakly curving apical spines.
REDESCRIPTION:
Male:
Mediumsized, nearly parallelsided; total length 3.90–4.75, length apex clypeus–cuneal fracture 2.40– 3.08, width across pronotum 1.12–1.25. COLORATION (fig. 8): General coloration of dorsum, including most of venter and appendages, dull reddish; venter slightly dark er; membrane weakly fumose, pale at angle between posterior margin of cells and posteromesal margin of cuneus; veins of membrane reddish; antennal segment 1 varying from entirely reddish to entirely castaneous, segment 2 frequently infuscate at base and apex (fig. 16), segments 3 and 4 castaneous; apex of labium infuscate; femora with some dark spots; tibial spines without dark spots at bases. SURFACE AND VESTITURE: Dorsum weakly granular, smooth, weakly shining. Vestiture of dorsum shaggy, composed of densely placed, reclining, golden, shining, simple setae. STRUCTURE: Body elongate, flattened, nearly parallelsided; frons weakly tumid, clypeus barely visible from above; anteocular distance equal to diameter of antennal segment 1; head projecting below level of antennal insertion by diameter of antennal segment 1; labium reaching to apex of middle coxae. GENITALIA (fig. 24): Vesica, including apical spines, more or less Jshaped, body relatively slen der, broadly curving, base falling near base of secondary gonopore; apical spines erect, slender, nearly cylindrical, weakly curving, and of nearly equal length; flange very narrow.
Female:
More strongly ovoid than male; coloration similar to male; frons more strongly protuberant. Total length 2.89–4.26, length apex clypeus–cuneal fracture 2.11– 2.86, width across pronotum 1.04–1.31.
HOSTS:
Symphoricarpos longiflorus
,
S. oreophilus
, S.
sp. (
Caprifoliaceae
);
Vaccinium
sp. (Ericaceae)
.
DISTRIBUTION: Known from
Nevada
,
Utah
, and western
Colorado
.
DISCUSSION: Knight (1964) described
fulvaceus
and
symphoricarpi
in separate genera. Comparison of Knight’s original material with additional specimens, and dissection of the male genitalia, indicates that these two nominal taxa are the same. The name
fulvaceus
has priority.
