The South American species of Pseudocanthon Bates, 1887 (Coleoptera: Scarabaeidae: Scarabaeinae: Deltochilini) are reviewed. In this work, 10 valid species and two subspecies are recognized for the genus. Among these species, five are recorded in South America, including three new species: P. perplexus (LeConte, 1847), P. xanthurus (Blanchard, 1847), P. vazdemelloi new species, P. pantanensis new species, and P. chaquensis new species. A lectotype is designated for P. xanthurus (Blanchard, 1847). In this revision, each species is analyzed as follows: a detailed literature review, an identification key for the South American species, a diagnosis, descriptions, illustrations of key morphological characters, list of examined material, and geographic distribution.

Generic boundaries of the South American species Panicum longipedicellatum Swallen are explored and compared with allied genera of the tribe Paniceae. On the basis of morphological, anatomical, and molecular characters a new genus, Cnidochloa Zuloaga, is proposed. The phylogenetic position of the new genus within the Paniceae is evaluated.

Mexican species of three pimpline genera, Apechthis Förster (one  species), Itoplectis Förster (six species) and Pimpla Fabricius (20 species, including one unidentified taxon), are reviewed. Four species of Pimpla are described as new to science: P. chamela sp. nov., P. oaxacana sp. nov., P. tequila sp. nov. and P. xalapana sp. nov. Pimpla thoracica Morley, 1914 is found to be a junior synonym of P. ellopiae Harrington, 1892 (syn. nov.). Apechthis zapoteca (Cresson) is recorded for the first time from Venezuela, Pimpla dimidiata (Townes) from Mexico, P. caeruleata Cresson, P. croceiventris (Cresson), P. sanguinipes Cresson and P. sumichrasti Cresson from Honduras, P. ichneumoniformis Cresson and P. viridescens Morley from Guatemala and Honduras, and P. punicipes Cresson from Panama. The South American species Pimpla caerulea Brullé and the Nearctic species P. pedalis Cresson are excluded from the Mexican fauna. Male of Itoplectis mexicana and female of Pimpla dimidiata are recorded for the first time. Identification keys to the species of Itoplectis and Pimpla occurring in Mexico are provided.

In this work, the Chrysomelinae leaf beetle subgenus Calligrapha s. str. Chevrolat, 1836 is revised, offering redescriptions and keys for identification of twelve species currently considered in this group, allied to the South American species Calligrapha polyspila (Germar, 1821), the generic type of Calligrapha. The current species count results from important taxonomic changes. These include reversing a long-held synonymy, resurrecting the name Calligrapha mexicana Stål, 1859 stat. rev. for a species that is different from Chrysomela serpentina Rogers, 1856; upgrading the status of Polyspila serpentina var. discrepans Achard, 1923 to Calligrapha discrepans (Achard) stat. rev.; and formally proposing a number of new synonymies for several species, including: (1) Calligrapha discrepans (Achard) (= Calligrapha serpentina ssp. temaxensis Bechyné, 1952 syn. nov.); (2) Calligrapha fulvipes (Gistel, 1848) (= Calligrapha bajula Stål, 1860 syn. nov.; = Calligrapha nupta Stål, 1859 syn. nov.; = C. sponsa Stål, 1859 syn. nov.); and (3) Calligrapha polyspila (Germar) (= Polyspila polyspila var. bilineolata Achard, 1923 syn. nov.; = Polyspila polyspila var. plagata Achard, 1923 syn. nov.).

Morphological boundaries between South American species of Euphrasia L. are controversial, rendering determination of specimens an arduous task. In this context, a comprehensive taxonomic revision of Euphrasia in South America is here provided for the first time. This study, based upon a classical morphological study of ca. 400 herbarium specimens, supports the recognition of eight species and one subspecies distributed in the Andean regions of Argentina, Bolivia, and Chile. From among native species, six belong to section Trifidae Benth. and one to the monotypic section Paradoxae Pugsley, endemic to Juan Fernández Islands; one adventive species, E. officinalis L., belongs to the section Euphrasia. The previously misunderstood presence of E. cockayniana Petrie is here untangled, and, consequently, the species is excluded from South America. A key to all Euphrasia taxa in South America, plus morphological descriptions, nomenclature items, geographical distribution and maps, habitat notes, illustrations, photographs, and discussion notes are included for the nine taxa. Eleven names are here synonymized, and lectotypes are designated for E. andicola Benth., E. debilis Wettst., E. flavicans Phil., E. intricata Phil., and E. philippii Wettst. Euphrasia andicola is reported for the first time for Argentina. This collaborative effort will represent a baseline for further investigations on Euphrasia in South America.

In this contribution we present updates on the taxonomy and morphology of the South American species of Amitermes. Two new species are described: Amitermes bandeirai, sp. n., from Brazil, and Amitermes lilloi, sp. n., from Argentina. Amitermes nordestinus is a junior synonym of Amitermes aporema. The imago of A. aporema is described for the first time. Detailed comparative gut anatomy of the eight species is presented for the first time. The geographic distribution of Amitermes in South America is expanded and the distribution patterns of some species are discussed.

São estudadas as espécies de Svastra Holmberg, da América do Sul: é descrita Svastra maculata sp. n., da Argentina; Svastra bombilans Holmberg, 1884 é considerada sinônimo únior de Svastra flavitarsis (Spinola, 1851); Svastra detecta Holmberg, 1884, permanece como boa espécie. ABSTRACT The South American species of the Neotropical genus Svastra are studied. Svastra maculata sp.n. from Argentina is described; Svastra bombilans (Holmberg, 1884 is considered junior synonym of Svastra latitarsis (Spinola, 1851) and Svastra detecta Holmberg, 1884 remains as a good species. RÉSUMÉ Les espêces du genre Svastra du Chile et de l'Argentina sont étudiés. Svastra maculata sp. n. est décrit. Svastra bombilans Holmberg, 1884. est considéré comme synonyme jeune de Svastra flavitarsis (Spinola, 185 1) et Svastra detecta Holmberg, 1884, une bonne espéce.
