Occurrence of phoresy between Ancistrus multispinis (Actinopterygii: Siluriformes) and Ichthyocladius sp. (Diptera: Chironomidae) in Atlantic forest streams, Southeastern Brazil 103
Mattos,Tailan Moretti; Carvalho,Dandhara Rossi; Brito,Mateus Santos de; Araújo,Francisco Gerson.
ABSTRACT Phoretic relationships often bring large advantages to epibionts. By attaching themselves to mobile hosts, epibionts are able to: expand their ranges without spending energy, reduce their risk of being predated, and increase their probability of finding food. We assessed the phoretic relationship between the siluriform fish Ancistrus multispinis (Regan, 1912) and the chironomid larva Ichthyocladius sp. in three streams of the Atlantic forest in southeastern Brazil. We evaluated changes in epibiont distribution throughout the body regions of the host and among three different aquatic systems. We had predicted that certain body regions are more prone to support epibiont attachment, and that epibiont prevalence increases with increased host size and...

Felippe-Bauer,Maria L.; Silva,Cristiane S..
Morphological alterations in six different species of females Culicoides Latreille, 1809 and one of Monohelea Kieffer, 1917 from Brazil, Mexico, Panama and Peru are described. The correlation of the morphological changes with the taxonomy and behavior of the species is discussed.
