Redescription of Licnophora chattoni Villeneuve-Brachon, 1939 (Ciliophora, Spirotrichea), associated with Zyzzyzus warreni Calder, 1988 (Cnidaria, Hydrozoa)

Licnophora chattoni, found in association with Zyzzyzus warreni, a tubulariid hydroid epizoic in sponges from Sao Sebastiao (SP, Brazil), is redescribed and illustrated using light and electron microscopy. The ciliate has a flexible, transparent body formed by an oval anterior region linked to the posterior basal disc via a flexible neck region. Numerous cortical granules are observed scattered throughout the body and densely packed along the neck. The adoral zone is formed by about 81 external and 24 infundibular paramembranelles. The paroral membrane, formed by a row of long cilia arranged in monolcinetids, extends through a groove in the body to the adhesive disc. Two dorsal kinetids are present along the right body margin and around the neck. The adhesive disc (18 mu m in diameter) lacks cilia in the area above the velum. The velum covers a row of dikinetids bearing long cilia and four dikineties, two or three of which are interrupted on the ventral surface. Nine to twelve macronuclear nodules connected by isthmuses are distributed in the cytoplasm, plus two nodules located in the adhesive disc and between those there is an ovate micronucleus.

New species of Fissiphallius Martens 1988 from Brazil and notes on the morphology of Fissiphalliidae (Arachnida, Opiliones)

The seventh species of Fissiphallidae, Fissiphallius orube sp. nov., and the fourth from Brazil (type locality state of Acre, Cruzeiro do Sul, at the Moa river), is described. The new species differs from the remaining species of the family in lacking a pergula, having a knob at the base of the rutrum, and the ocularium spiniform projection with apical portion single or divided in two to three parts.
