Revision Of New World Plagiognathus Fieber, With Comments On The Palearctic Fauna And The Description Of A New Genus (Heteroptera: Miridae: Phylinae) Author SCHUH, RANDALL T. text Bulletin of the American Museum of Natural History 2001 2001-11-08 2001 266 1 267 http://www.bioone.org/doi/abs/10.1206/0003-0090%282001%29266%3C0001%3ARONWPF%3E2.0.CO%3B2 journal article 10.1206/0003-0090(2001)266<0001:RONWPF>2.0.CO;2 0003-0090 5381844 Plagiognathus rosicola Knight, 1923: 446 (n. sp.). DIAGNOSIS: Recognized by the very long labium extending to about the middle of the abdomen, dorsal vestiture reclining to sub­ erect, anteocular distance almost 2 times diameter of antennal segment 1 (fig. 38A), and the usually red­orange general coloration (fig. 12) with the clypeus and maxillary plate contrastingly castaneous and polished. Most similar in coloration to fulvaceus (fig. 8) and concoloris (fig. 7), but easily distinguished from those species by the very long labium, more slender body form, and occurrence in eastern North America. Similar to albifacies (fig. 5) in the long labium and semierect dorsal vestiture, but distinguished by that species having the clypeus and adjoining face mostly pale, having antennal segment 1 mostly pale, having a less strongly projecting head, and by its occurrence on Polymnia rather than on Rosa .

REDESCRIPTION: Male: Moderately large, elongate; total length 4.05–4.60, length apex clypeus–cuneal fracture 2.89–3.22, width across pronotum 1.23–1.33. COLORATION (fig. 12): General coloration, including most of venter and appendages, orange to reddishorange; clypeus and maxillary plate castaneous and contrasting with remainder of head; membrane heavily fumose, narrowly pale adjacent to posteromesal margin of cuneus and including vein on posterior margin of small cell; antennae black except for pale apical annulus on segment 1 and narrow pale annulus at base of segment 2 (fig. 18); labium usually castaneous near base and apex; femora with numerous dark spots; dorsal tibial spines with dark spots at bases; tibiae dark at femoral articulation. SURFACE AND VESTITURE: Dorsum weakly granular, smooth, weakly shining. Vestiture of dorsum composed of recumbent, relatively long, simple setae unicolorous with dorsum (fig. 38C). STRUCTURE: Body moderately slender, nearly parallel­sided; head distinctly projecting anteriorly, clypeus visible from above; anteocular distance 2.0 times diameter of antennal segment 1; head projecting below eye by at least 1.5 times diameter of antennal segment 1 (fig. 38A); labium very long, reaching to anterior margin of genital capsule in some specimens; metathoracic scent­gland evaporatory area and spiracle as in figure 38B; pretarsus as in figure 38D. GENITA­ LIA (fig. 31): Vesica relatively large, body moderately broad; apical spines weakly angled relative to body of vesica, elongate and relatively slender; flange narrow, barely extending past body of vesica and terminating well below base of secondary gonopore. Female: Body ovoid, broader than in male; coloration sometimes not so intensely orange as in male. Total length 4.16–4.56, length apex clypeus–cuneal fracture 2.98– 3.25, width across pronotum 1.31–1.41. HOSTS: Rosa carolina , R. spp. ( Rosaceae ). DISTRIBUTION: Eastern North America, ranging from Prince Edward Island in the north, south to South Carolina , and west to Illinois . DISCUSSION: My concept of this species is based on the examination of paratypes listed under Specimens Examined, and on other material that I consider to be authoritatively identified.
