The new genus Yanomamius n. gen. from Brazilian and Venezuelan Amazon is described, with three new species from Brazil: Y. franciscoi n. sp. (type species), Y. raonii n. sp., and Y. neblina n. sp. The enigmatic Venezuelan species described as Holothele waikoshiemi Bertani & Araújo, 2006 and presently included in Guyruita Guadanucci et al. (2007) is transferred to the new genus, making the new combination Y. waikoshiemi (Bertani & Araújo, 2006) n. comb. Yanomamius n. gen. is closely related with the schismatotheline genera Schismatothele Karsch, 1879 and Euthycaelus Simon, 1889 sharing as probable synapomorphies a group of short spines on the retrolateral distal tibia of male palp and the shape of bulb. They differ by the position of the spines in a compact group instead of in rows and by a tapering embolus. Females differ from Schismatothele and Euthycaelus by the spermathecae weakly sclerotized. A series of recent phylogenies based on molecular data suggested a close relationship between schimatothelines and psalmopoeines. The male tibia I of Yanomamius n. gen. species have a series of ridges or a single protuberance behind the tibial apophyses that resemble those of psalmopoeines and strengthen the idea of close relationship of the two subfamilies.

The circumscription and morphological characterization of the deltocephaline tribe Acostemmini is revised based on dis-coveries of new and poorly known taxa from recent collections in Madagascar and from examination of the type speci-mens of Alocoelidia fulva Evans, Iturnoria insulana Evans, and Protonesis delegorguei Spinola. Alocoelidia Evans 1954,Caelidioides Signoret 1880, Iturnoria Evans 1954, and Protonesis Spinola 1850 were previously placed in Coelidiinaebut were later removed from the subfamily and until now have been unplaced to subfamily are placed here in Deltocepha-linae: Acostemmini, new placement. A new genus and species, Ikelibeloha cristata gen. n., sp. n., are described that havean unusually modified structure of the head and a large, crested pronotum. Molecular data (28S, Histone H3 genes) wereobtained for Ikelibeloha and Iturnoria, and analyzed with other members of Deltocephalinae. Results of the phylogeneticanalyses show strong support for the monophyletic clade ((Acostemma, Eryapus), (Ikelibeloha, Iturnoria)) and thus a re-lationship between previously described Acostemmini, Ikelibeloha, and Iturnoria has strong statistical support, and aclose relationship is inferred between these and the morphologically similar Alocoelidia, Caelidioides, and Protonesis.Two new species of Alocoelidia, A. maurae sp. n. and A. chasei sp. n. are described, and the genus is redescribed. Themale genitalia of Caelidioides tristis (Signoret), Iturnoria insulana, Alocoelidia fulva, and Acostemella rubra Evans areillustrated and described for the first time. The female genitalia of A. fulva, C. tristis and I. insulana are described and thefirst and second valvulae of C. tristis are illustrated. The habitus and face of Protonesis delegorguei are illustrated and thegenus is redescribed. The characters traditionally used to define Acostemmini are reviewed with notes on their known de-grees of variation, and characters that differentiate Acostemmini from the closely related tribe Stegelytrini are discussed.The type of Malagasiella minima Evans was also examined, and Malagasiella Evans, 1954 is considered a junior syn-onym of Doratulina Melichar, 1903 (Deltocephalinae: Stenometopiini), syn. n. giving the new combination Doratulina minima (Evans) comb. n.

Two new genera and three species of the Pantheinae are described. The genus Flavala gen. n. (type-species Acronycta flavala Moore, 1867) is separated from Anacronicta Warren, 1909. The new combination Flavala flavala (Moore, 1867) comb. n. is introduced. Two new species, Flavala crypta sp. n. and F. secunda sp. n. are described based on the result of barcoding of mitochondrial DNA. The new genus Xizanga gen. n. (type-species Xizanga mysterica sp.n.) is tentatively placed in Pantheinae.

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.

AbstractThe new genus Halegrapha is introduced, with six species (five new species and one new combination) from Australia, the Philippines, Malaysia, Kenya, Mexico, and the United States: H. chimaera Rivas Plata & Lücking (type species; Philippines), H. floridana Common & Lücking (United States: Florida), H. intergrapha Hale ex Lücking (Malaysia), H. kenyana Kalb & Lücking (Kenya), H. mexicana A. B. Peña & Lücking (Mexico), and H. mucronata (Stirt.) Lücking (Australia). The genus resembles Graphis morphologically in the strongly carbonized, black lirellae and white-grey thallus strongly encrusted with calcium oxalate crystals, but has a Phaeographis-type hymenium (clear in two species) and ascospores, making it a ‘chimera’ between the two genera. Molecular data suggest the genus to be closely related to Phaeographis and allies but genetically distinct from any of the genera currently recognized, including Platygramme.

AbstractThe crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1–2 per ascus in strongly pigmented biatorine apothecia. The monophyly of Mycoblastus and the relationship of its various species to Tephromelataceae have never been studied in detail. Data from ITS rDNA and the genes coding for translation elongation factor 1-α and DNA replication licensing factor mini-chromosome maintenance complex 7 support the distinctness of Mycoblastus s. str. from the core of the Tephromelataceae, but recover M. fucatus and an undescribed Asian species as strongly supported within the latter group. We propose accommodating these two species in a new genus, Violella, which is characterized by its brownish inner ascospore walls, Fucatus-violet hymenial pigment granules and secondary chemistry, and discuss the position of Violella relative to Calvitimela and Tephromela. We describe the new species Violella wangii T. Sprib. & Goffinet to accommodate a new species with roccellic acid from Bhutan, China, India and the Russian Far East. We also exclude Mycoblastus indicus Awasthi & Agarwal from the genus Mycoblastus and propose for it the new combination Malmidea indica (Awasthi & Agarwal) Hafellner & T. Sprib.

Studies on the Agalliini leafhoppers collected from the Terrestrial Arthropods of Madagascar inventory project of the Cal-ifornia Academy of Sciences, resulted in the discovery of one new genus Agallidwipa gen. nov. (type-species: A. biramosa sp. nov.) with three new species, A. biramosa sp. nov., A. bispinosa sp. nov. and A. webbi sp. nov. and three new species of the genus Igerna Kirkaldy, I. delta sp. nov., I. flavocosta sp. nov. and I. malagasica sp. nov. Two new combinations proposed are Agallidwipa pauliana (Evans) comb. nov. (from genus Agalliana Oman) and Igerna neosa (Webb) comb. nov. (from genus Stonasla White), a species previously recorded from Aldabra Islands. A previous record of Igerna bi-maculicollis (Stål) from Madagascar is shown most likely to be a case of misidentification. All the taxa are described and illustrated. Keys to species of Agalliini from Madagascar are included along with notes on the distinction between Agal-liana and Agallidwipa.
