Tornabenea is a small Apiaceae genus that is endemic to the Cape Verde Islands. Its species differentiation is based just on a few macromorphological characters: leaf shape, number and shape of umbel bracts and mericarp ribs. These characters vary within each species and show high plasticity. Thus, in recent taxonomic data of the genus, there are different viewpoints as to the number of species. Here, in order to improve the taxonomy of the genus, microcharacters of the vegetative and reproductive structures of three taxa-T. insularis, T. annua and T. tenuissima-have been examined. The shape and arrangement of hairs on the surface of the mericarps, and the presence and structure of starch grains are the only different microcharacters noted in T. insularis and T. annua. Chromosome number of the latter two species is 2n ¼ 18. Our preliminary results disagree with the existing classifications of the genus Tornabenea. In fact, they do not lead to a clear separation between T. insularis and T. annua. By contrast, it is easy to distinguish between these species and T. tenuissima, which possesses more peculiar microcharacters.
Descrição da Fêmea de Aguatala compsa Yo ung (Hemiptera: Cicadellidae: Cicadellinae) RESUMO -A fêmea de Aguatala compsa Yo ung é descrita e ilustrada pela primeira vez com base em espécimes provenientes da Colômbia, consistindo em novo registro de distribuição para o gênero monotípico Aguatala Yo ung. A genitália feminina de A. compsa é detalhadamente descrita e comparada com aquelas de gêneros supostamente próximos, pertencentes ao grupo genérico Erythrogonia (sensu Yo ung).
PALAVRAS-CHAVE: Cigarrinha, morfologia, Membracoidea, CicadelliniABSTRACT -The female of Aguatala compsa Yo ung is for the first time described and illustrated based on specimens from Colombia. This consists also on a new distribution record for the monotypic genus Aguatala Yo ung. The female genitalia of A. compsa are described in detail and compared with those of supposedly related genera belonging to the Erythrogonia generic group (sensu Yo ung).

A new species of Euragallia Oman, 1938 from Peru (Pasco Department) is described and illustrated. Euragallia batmani
sp. n. can be distinguished from the other species of the genus by the very posteriorly pronounced male pygofer, with an apical hook-like projection, and by the well-developed dorsal area of the aedeagal base, resembling the open wings of a bat. With the addition of Euragallia batmani sp. n., the number of Euragallia species is increased to 21. Only one additional species of the genus is recorded from Peru (Euragallia prion Kramer, 1976). A comparison between the new species and Euragallia prion is provided. A conspicuous structure, which connects the subgenital plates to the styles, is described in detail and named.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
