Rubiacearum Americanarum Magna Hama Pars XXXII. New Species and a New Combination in Coussarea (Coussareeae) from Western South America

The Ochlerini (Discocephalinae) are endemic in the Neotropical region, and the tribe currently contains 38 genera and 149 species. The monotypic Macropygium Spinola, 1837 is the most widespread ochlerine genus in the Americas, ranging from Mexico to Argentina. Macropygium reticulare (Fabricius, 1803) is one of the few Ochlerini of phytosanitary importance, transmitting Phytomonas spp. in palm crops in South America. Nonetheless its wide distribution, and phytosanitary importance, the taxonomy of Macropygium has been neglected. Here we present a revision of Macropygium, revalidate three species, Macropygium spinolae Stål, 1860, REVISED STATUS (removed from the synonymy with M. reticulare), Macropygium bifidum (Westwood, 1837), NEW COMBINATION (removed from the synonymy with M. reticulare), and Macropygium subsulcatum (Amyot & Serville, 1843), REVISED STATUS (removed from the synonymy with M. reticulare). We remove Ochlerus guttipes Walker, 1867 from the synonymy with M. reticulare, and propose O. guttipes a new junior synonym of M. spinolae. Finally, we describe one new species, Macropygium graziae Silva & Campos, Sp. Nov.. A key for the species of Macropygium is provided.

Stenonartonia is a neotropical genus restricted to the forested regions of South America east of the Andes. The genus is revised here and numbers 14 species. Nine new species S. hasyva sp. nov., S. perdita sp. nov., S. cooperi sp. nov., S. guaraya sp. nov., S. rejectoides sp. nov., S. occipitalis sp. nov., S. tanykaju sp. nov., S. hermetica sp. nov., S. grossa sp. nov. are discribed and illustrated. New combination is proposed for S. mimica (Kohl), comb. nov. (from Paranortonia). Lectotype is designated for Nortonia polybioides von Schulthess. A key, along with full descriptions, illustrations of morphological features and distribution maps for all of the species are given.

Three New Species

AbstractThe species of Aphidini living on Senecio L. in South America are reviewed. Pehuenchaphisgen. nov. is described; it is an Aphidina genus characterized mainly by the siphunculi on abdominal segment VI when present and by its radicicolous way of life. The type species of the genus Pehuenchaphis agilissimasp. nov. is described and the new combination Pehuenchaphis americana for Sene ciobium americana Mier Durante and Ortego is established. Aphis senecionicoides E.E. Blanchard is redescribed and its neotype is established. Aphis papillosasp. nov. with very large marginal papillae and Aphis malalhuinasp. nov. with short siphunculi are described and differentiated from the previously known Aphis intrusa Ortego and A. senecionicoides. A key for the apterous viviparous females of these seven species and Andinaphis paradoxa Mier Durante et al. is given.

One New Species

AbstractTwenty-three species of Pyrenula from Latin America are treated here. Several species show characters that were not previously reported in the genus and are rare or new to lichenized fungi, viz. yellow, orange or red (KOH+ green) oil inspersion in the hymenium, yellow oil in young ascospores or longitudinal ridges on the ascospore wall. Two taxonomically significant types of over-mature spores are illustrated. The following new species are described: Pyrenula aggregataspistea Aptroot & M. Cáceres, P. aurantioinspersa Aptroot & Sipman, P. cornutispora Aptroot & M. Cáceres, P. flavoinspersa Aptroot & Sipman, P. guyanensis Sipman & Aptroot, P. infraleucotrypa Aptroot & M. Cáceres, P. inframamillana Aptroot & M. Cáceres, P. infrastroidea Aptroot & Sipman, P. maritima Sipman & Aptroot, P. mattickiana Sipman & Aptroot, P. minoides Aptroot & Sipman, P. monospora Aptroot & Sipman, P. paraminarum Aptroot & M. Cáceres, P. perfecta Aptroot & Sipman, P. plicata Sipman & Aptroot, P. rubroinspersa Aptroot & Sipman, P. rubronitidula Aptroot & M. Cáceres, P. rubrostigma Aptroot & M. Cáceres, P. tetraspora Aptroot & Sipman, P. triangularis Aptroot & Sipman, P. viridipyrgilla Aptroot & M. Cáceres. Pyrenula seminuda (Müll. Arg.) Sipman & Aptroot is a new combination.
