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 punctatipes Knight, 1923: 450 (n. sp.). DIAGNOSIS: Recognized by the generally castaneous coloration, ovoid body, neatly arranged, recumbent, golden, shining vestiture of dorsum (figs. 12, 37B), pale antennal segment 2 except at extreme base (fig. 18), femora mostly pale with some dark blotches, and tibiae pale at articulation with femora. Distinguished from the similar­appearing species dispar (fig. 7) and rileyi (fig. 12) by the more strongly ovoid body form, the uniformly castaneous dorsum totally lacking in pale orna­ mentation, and the tibiae pale at articulation with the femora. REDESCRIPTION: Male: Ovoid, of moderate size; total length 3.39–3.54, length apex clypeus–cuneal fracture 2.38–2.54, width across pronotum 1.14–1.22. COLORATION (fig. 12): Dorsum deeply and uniformly castaneous, never with pale markings; membrane fumose, veins vaguely pale; face more highly polished at and below base of clypeus than elsewhere; antennal segment 1 castaneous except for pale apical annulus, segment 2 dark at extreme base, remainder of segment pale, segments 3 and 4 pale; labium often largely infuscate, segment 1 usually castaneous; venter, including metathoracic scent­gland evaporatory area, entirely castaneous; legs, including coxae, pale, golden, except coxae sometimes partially infuscate basally and hind femora with some dark spots; dorsal tibial spines with small dark spots at bases; tibiae pale at articulation with femora. SURFACE AND VESTITURE: Dorsum weakly granular, smooth, distinctly although not strongly shining. Vestiture of dorsum composed of neatly arranged, recumbent, golden, shining, simple setae (fig. 37B). STRUCTURE: Body ovoid, corial margins distinctly convex; frons weakly convex as viewed from above, clypeus barely visible; anteocular distance no greater than diameter of antennal segment 1; head projecting below eye by 2 times diameter of antennal segment 1 (fig. 37A); labium reaching to about apex of middle coxae; pretarsus as in figure 37C. GENITALIA (fig. 30): Body of vesica more or less J­shaped, base of vesica falling slightly below level of secondary gonopore, posterior apical spine relatively broad, weakly curvilinear, obliquely angled relative to body of vesica, anterior spine elongate and at nearly right angle to body of vesica; flange on vesica relatively narrow, reaching to base of gonopore.

Total length 3.48–3.72, length apex clypeus–cuneal fracture 2.42– 2.74, width across pronotum 1.18–1.23. HOSTS: Known to breed on Physocarpus opulifolius (Rosaceae) (Wheeler and Hoebeke, 1985) and Viburnum spp. (Caprifoliaceae) . Recorded from several of other plant groups, but with little evidence of breeding. DISTRIBUTION: Northeastern North America, as far west as Illinois and as far south as West Virginia .
