Record of two species of Orius Wolff (Hemiptera, Anthocoridae) in Brazil

The genus Orius Wolff, 1811 comprises predatory species, with approximately 70 known species. Informations about the genus in Brazil are scarce. Therefore, the aim of this investigation was to identify Orius species present in four localities in the southeastern Brazil. Samples were taken from several plants, and the material screened in laboratory. The genitalia of both sexes were studied and illustrated. Two species were identified, Orius insidiosus (Say, 1832) and Orius thyestes Herring, 1966. O. insidiosus, the most common species, was collected in all of the localities sampled [Lavras (MG), Holambra, Pindorama and Campinas (SP)]. O. thyestes, registered for the first time in Brazil, occurred only in Lavras (MG) and Pindorama (SP). Some morphologic aspects of these two species are also presented.

Phoenix in the Cape Verde Islands

The African Republic of Cape Verde consists of nine inhabited and several uninhabited volcanic islands set out in the Atlantic Ocean, about 500 km off the most westerly point of the African mainland and 1500 km south of the Canary Islands @g. 2). Most are rugged and mountainous; three (Sal, Maio, and Boavista) are flat, desert islands with sand beaches. Precipitation is meagre and very erratic; indeed Cape Verde can be seen as an island extension of the arid Sahel zone. Three species of the genus Phoenix are recorded from the Cape Verde Islands, P. akzctyli&a L., P. canariensis Chabaud and P. atlantica A. Chev. While the former two species have almost certainly been introduced by man, the latter is said to be endemic to the islands. Perhaps because the Cape Verdes are a particularly isolated set of islands or because palms are notoriously awkward to collect, little is known about the taxonomy, origins and natural history of this species. Phoenix atlantica was described by the French botanist Auguste Chevalier (1935a) following field exploration in the Cape Verdes in 1934 (Chevalier 1934: 1153). Chevalier provided limited diagnostic characters, defining the species as a clustering palm with 2-6 trunks, 5-15 m in height with dark green leaves 2-3 m in length. He considered it to be most similar in form to P. &ctyZzjkra and P. canariensis, possessing characters of both (Chevalier 1935a). Chevalier’s description indicates that Phoenix atlantica can be distinguished easily from P. canariensis by its clustering growth form (P. canariensis always has a single, stout trunk) and its shorter, straighter leaves. However, the differences between P. atlantica and P. dactylzjkra appear much more subtle. For example, while P. dacfylifera is usually observed as single-stemmed, when left undisturbed for a number of years it becomes clustering like the Cape Verde Phoenix, so this character on its own is unreliable. Further alleged distinctions include acuminate (P. atlantica) versus rounded (P. dactylzjkra) petals in the male flowers (Chevalier 1935a, b, Greuter 1967: 249, and Brochmann et al. 1997), fruit 2 cm long (P. atlantica) versus fruit more than 2.5 cm long (P. dactyl&a) (Brochmann et al.

Análise cladística da tribo Rhopalophorini Blanchard, 1845 (Coleoptera, Cerambycidae)

Rhopalophorini is primarily a New World group. Of the 23 known genera, 19 were described from the Neotropical region. A cladistic analysis of the American genera was carried out with 91 morphological characters. The genera Ozodes Audinet-Serville and Lissozodes Bates, recently transferred to Necydalopsini, were included in the analysis in order to investigate their relationships with the Rhopalophorini. The results suggested that their shared similarities with the Rhopalophorini are symplesiomorphies at the level considered in the analysis, so they are maintained in Necydalopsini, and Neozodes Zajciw, indicated as the sister group of Ozodes, is herein transferred to this tribe. In the same way, Elaphopsis Audinet-Serville is transferred to Ibidionini. Rhopalophorini, as defined in the present work, is a monophyletic group and includes 17 American genera. Within Rhopalophorini, Argyrodines + Parozodes constitute the basalmost group, and Cycnoderus is the sister group of the two major clades formed, one by Ischionodonta, Disaulax, Cosmisoma, Closteropus and Gurubira, and the other, by Rhopalophora, Coremia, Merocoremia, Dirocoremia, Thalusia and Lathusia; the relationships of Rhopalophorella, Rhopalina and Muxbalia remain inconclusive. A phylogenetic classification of Rhopalophorini at the genus level is proposed.
