description: Anommatocoris bolivianus, new species Figures 1, 2, 4, 5, 7, 8 <b>Description.</b> <i>Body</i> uniformly clear brown, shiny, coarsely punctate, pilose, setae long, suberect, and sparsely distributed on coriaceous part of hemelytra, clypeus, and antennae. Body length, 2.33; width, 1.33 mm. <i>Head</i> glabrous, unarmed; eyes well developed; clypeus short, pilose; bucculae narrow, open in front, with a row of punctures along entire length; antennae inserted in front of eyes, without antenniferous process at base, segment 1 surpassing apex of head, articles thicker at apex than at base; antennal segment 1 shortest, segments 2, 3, and 4 subequal in length, all covered with long, sparse setae; labium relatively long, almost reaching apex of metasternum. <i>Pronotum</i> trapeziform, much wider posteriorly than anteriorly, wider than long, flat, glabrous, posterior margin weakly sinuous, with a longitudinal suture in the middle on posterior part, punctate on most of the surface; collar narrow, with a row of small punctures; scutellum visible, triangular, moderately large; labial sulcus on thoracic venter narrow, sinuous, slightly curved, open behind, laminae slightly raised, not areolate. Legs slender; hind tarsi long, four times as long as wide, pilose beneath. <i>Hemelytra</i> macropterous, about as wide as pronotum, costal margins nearly straight and parallel, with a fringe of long, erect setae; costal vein extending to apex of hemelytron; subcostal area narrow, slightly wider than costal area, sloping downward, with two rows of punctures; R + M raised, ridge-like; discal area elongate triangular, with irregularly distributed punctures, each bearing a relatively long, suberect seta; clavus well developed, with irregularly distributed setose punctures, claval commissure long; membrane long, extending well beyond apex of abdomen, without veins. <b>Types.</b> Holotype, male: BOLIVIA, <b>Depto. La Paz</b>, Chulumani, Apa-apa, 16 <i>°</i> 22 <b>9</b> S 67 <i>°</i> 30 <b>9</b> W, 1–4.V.1997, 1800 m, L. Masner, YPT B9-11 [collected by screen sweeping in understory vegetation]. Deposited in the American Museum of Natural History (AMNH), New York. Paratypes: BOLIVIA, <b>Depto. La Paz</b>,: 2 males, same data as holotype (AMNH; Australian Museum). <b>Discussion.</b> <i>Anommatocoris bolivianus</i>, known only from the macropterous form, displays several morphological similarities with the remaining Recent species of Vianaidinae, all of which are known only from coleopteroid morphs. Features shared in common include the punctate dorsal body surface (figs. 1A, 2A, B), the metathoracic external scent-efferent system (figs. 5A, B, D, E) with a T-shaped peritreme, the evaporatory area covering the entire metepisternum, and the form of the undissected male genitalia. Further comparison of <i>A. bolivianus</i> and other Recent vianaidines is confounded by the largely non-overlapping aspects of morphology. These include the compound eyes, whichin <i>A. bolivianus</i> arewelldeveloped, nearlyholoptic, andcomposedof,100 facets (fig. 1A, B, 4A, B), whereas in the coleopteroid species the eyes are at most very weakly developed, with a few laterally disposed facets (fig. 4C, D). Most obvious is the divergent structure of the forewings. Because of the highly modified wings in all prior known Tingidae, it was difficult to understand just what kind of transformations might have taken place to produce the completely areolate forewings lacking a membrane or the coleopteroid structure found in all prior known Vianaidinae. Nonetheless, the major features of the wing structure in macropterous Vianaidinae could possibly have been predicted from the submacropterous amber fossil described by Golub and Popov (2000), a view that is substantially clarified by the macropterous specimens of <i>A. bolivianus</i>. With regard to wing polymorphism in the Heteroptera, it is well known that wingshortening is often correlated with morphological variation of other characters, such as eye and pronotal shape, and sometimes even male genitalic structure. Nonetheless, we believe that even in the face of such influences, the substantial similarity of structure in the head and pronotum of <i>A. bolivianus</i> with described coleopteroid species of <i>Anommatocoris</i>, militates for their status as congeners. We treat <i>A. bolivianus</i> as a distinct species, however, finding little morphological evidence that would allow us to positively ally the macropterous specimens on which the present paper is based with any of the known coleopteroid forms.
