The objective of this work was to analyze the spatial distribution and the behavior of species richness and diversity in a shrub savanna fragment, in 2003 and 2014, using ordinary kriging, in the state of Minas Gerais, Brazil. In both evaluation years, the measurements were performed in a fragment with 236.85 hectares, in which individual trees were measured and identified across 40 plots (1,000 m2). Species richness was determined by the total number of species in each plot, and diversity by the Shannon diversity index. For the variogram study, spatial models were fitted and selected. Then, ordinary kriging was applied and the spatial distribution of the assessed variables was described. A strong spatial dependence was observed between species richness and diversity by the Shannon diversity index (<25% spatial dependence degree). Areas of low and high species diversity and richness were found in the shrub savanna fragment. Spatial distribution behavior shows relative stability regarding the number of species and the Shannon diversity index in the evaluated years. |

The Neotropical psyllid genus Tainarys Brèthes, 1920 is revised to include 14 extant and one fossil species from Dominican amber. Eight species are described as new, viz. Tainarys aroeira sp. nov., T. atra sp. nov., T. hapla sp. nov., T. myracrodrui sp. nov., T. nigricornis sp. nov., T. didyma sp. nov. and T. orientalis sp. nov. from Brazil, the last two also from Uruguay, as well as T. lozadai sp. nov. from Peru. The fifth instar immatures are described for nine species. ?Vicinilura Klimaszewski, 1996, erected for the fossil ?V. reposta Klimaszewski, 1996 and previously synonymised with Leurolophus Tuthill, 1942, is synonymised here (syn. nov.) with Tainarys and ?V. reposta is transferred to become ?Tainarys reposta (Klimaszewski), comb. nov. The descriptions are supplemented by illustrations and keys for the identification of adults and immatures. Phylogenetic relationships between species are investigated with a cladistic analysis using 22 adult and six immature morphological characters. The analysis resulted in a single most parsimonious, fully resolved tree. The fossil species is nested within the genus rather than being the sister taxon of the remainder of species. The extant species are restricted to the subtropical and temperate parts of South America. Three pairs of sister clades display an east‒west South American and one a midwest‒southern Brazilian geographical vicariance. Host plants are confirmed for nine and likely for another four species. They are Astronium, Haplorhus, Myracrodruon, Schinopsis and Schinus (Anacardiaceae). All Tainarys species appear to be oligophagous inducing irregular leaf curls on their hosts.
