In Fortsentzung des Kataloges der suedbrasilianischen Baumpollen untersuchten wir die Familien Cunoniaceae, Rosaceae und Connaraceae. Die erste besitzt sehr kleine Pollenkoerner, mit zwei (Lamanonia speciosa) oder drei colpori und netzartigen Ober-flaechen. Die Rosaceen haben groessere Koerner mit drei colpori und such, ausser Licania sp., feinere netzartige und gerillte Sexine. Die Connaraceen, mit drei colpori, haben ein etwas grossmaschigeres reticulum. Groessere Aehnlichkeiten wurden festgestellt zwischen den Pollenkoernern der Connaraceae und den der Dilleniaceae und Marcgraviaceae. Mit sicherheit konnten wir keine phylogenetische Reihenfolge der Pollenkoerner der drei bearbeiteten Familien aufstellen.Resumo em Inglês:
Buprestid leaf-miners are generally included in the subtribe Trachytes. The genera belonging to this subtribe are commonly very rich in number of species and their systematics envolves huge difficulties. On the other hand the biological knowledge on those insects is very poor. The A. tries to clarify the systematical status of two species of Pachyschelus - P. subundulatus Kerr. and P. fulgidipennis Lucas, and redescribes also P. binderi Obenberger. The hosts of the first two species are recorded, namely: Terminalia catappa (Combretaceae) - host-plant of P. subundulatus and Luhea spp. (Tiliaceae) - host-plant of P. fulgidipennis. The mines, developmental stages and habits of the three species are described and is made a full redescription of the adults, both male and female. The study is based on reared material from mined leaves, as well as insects assembled in several brazilian collections, both private and public ones. The importance of some biological facts as well as some morphological characters are stressed. The knowledge of the host-plants and the shape and other structural features of the mine were found to be helpfull to the identification of the species. Some morphological features of adults also prooved to be of systematical value. Besides the female pygidium and the male genitalia, the tibiae of the third pair of legs show some intersting structural details, reasonably alike in both sexes and quite different in each species.Resumo em Inglês:
The author studies the genera Rhopalomera Wiedemann, 1824 and Willistoniella Mik, 1895, pointing out the remarkables differentces between them. Describes Rhopalomera stictica (wiedemann, 1828), Rhopalomera clavipes (Fabricius, 1805) and Willistoniella peluropunctata (Wiedemann, 1824).Resumo em Inglês:
The authors describe the egg, larva and pupa of P. bahiensis Mangabeira & Sherlock, 1961, from material collected in Salvador, Bahia. As it was oberved, they do not present any morphological characteristic that would separate them from other species. The Authors call attention for the presence of an anomalous cerda in the larva.
