Plagiognathus luteus
Knight, 1929b: 72
(n. sp.).
DIAGNOSIS: Recognized by
moderate size,
intense, uniform,
orange coloration
(fig. 9), and
antennal segment 1 black
(fig. 17). Size and coloration of body similar to
vitellinus
(fig. 14), but easily separated by black antennal segment 1.
REDESCRIPTION:
Male:
Elongate, of medium size; total length 3.43–3.68, length apex clypeus–cuneal fracture 2.37–2.52, width across pronotum 0.97–1.10. COLORATION (fig. 9): General coloration intensely and uniformly orange; membrane pale, whitish, with orange veins; antennal segment 1 black, except for pale apical annulus, segment 2 dark at base and infuscate near apex (fig. 17), segments 3 and 4 infuscate; labium infuscate at apex; hind femora usually with a black stripe near apex on dorsal surface; dorsal tibial spines with dark spots at bases; tibiae black at articulation with femora. SURFACE AND VESTITURE: Dorsum weakly granular, dull. Vestiture of dorsum composed of recumbent pale, golden, shining, simple setae. STRUC TURE: Corial margins nearly straight; frons weakly swollen, clypeus visible from above; anteocular distance 1.5 times diameter of antennal segment 1; head projecting below eye by diameter of antennal segment 1; labium reaching to about apex of hind coxae or slightly beyond. GENITALIA (fig. 26): Vesica, including apical spines, sigmoid, relatively slender and of more or less uniform thickness over length of body, base of vesica falling below base of secondary gonopore; apical spines only moderately elongate, relatively slender, superposed, smoothly curving, anterior spine slightly shorter than posterior; flange narrow.
Female:
Body form more compact and strongly ovoid than in male; coloration similar to male although often not so intensely orange. Total length 3.28–3.50, length apex clypeus–cuneal fracture 2.29–2.42, width across pronotum 1.00–1.13.
