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.

AbstractA new monotypic genus, Bolbothyreus, is proposed for the South American species Stenaspidius ruficollis (Bruch). The new genus seems most closely related to Bolbapium Boucomont from South America and less so to Stenaspidius Westwood from Australia.

A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysusand Liosomadoras, and Pseudotatiaand Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeriaas sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodorasand two monophyletic groups: Astrodoradinae (plus Acanthodorasand Agamyxis) and Doradinae (new arrangement). Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochirand Platydoras, the other with the large-size species of doradids (except Oxydoras), another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydorasplus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N. leporhinusand Nemadoras ternetzi. Due to conflicting hypotheses of the phylogenetic position of Acanthodoras, Agamyxis, and Franciscodoras, these are considered as incertae sedisin Doradidae. All suprageneric taxa of the Doradoidea are diagnosed based on synapomorphic morphological characteristics.

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.).

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.
