New records, descriptions, and redescriptions of male horse flies (Diptera: Tabanidae) in Brazil
2023
Lia Pereira Oliveira | Augusto Loureiro Henriques | Tiago Kütter Krolow
Tabanidae Latreille are hematophagous and act as mechanical and biological vectors of several pathogens, and therefore they have been widely studied in both ecology and public health, as well as in taxonomy works. Males are nectarivorous and rarely captured, so for most species they remain unknown. Thus, we aimed to describe/redescribe the males of five species: Esenbeckia osornoi Fairchild, 1942, Acanthocera marginalis Walker, 1854, Dicladocera mutata Fairchild, 1958, Stypommisa aripuana Fairchild & Wilkerson, 1986, and Tabanus mucronatus Fairchild, 1961. Three males are described for the first time and two others are redescribed, we also provide a complete description of the species, including photographs of habitus, head and genitalia.
Afficher plus [+] Moins [-]Characterization of entomogenic galls in areas of seasonal deciduous forest in Southwestern Bahia, Brazil
2023
Lúcio Flávio Freire Lima | Juvenal Cordeiro Silva Junior
Galls are small structures induced mostly by insects in different plant organs, and have different shapes and colorations. Knowledge on galls is still sparse in the semiarid region of Bahia. Therefore, the goal of this study was to characterize galls in fragments of seasonal deciduous forest. Sampling was performed in the Bahia municipalities of Boa Nova, Jequié, Poções and Vitória da Conquista. In each site, one fragment was chosen, and in each fragment, plots were established to survey galls on vegetation. We sampled 158 gall morphotypes, representing 49 (morpho) species distributed across 15 families of host plants. Myrtaceae and Malphigiaceae had the highest numbers of gall morphotypes. Most galls were collected from leaves, whereas the most common gall morphotypes were globoid and fusiform.
