A redescription of a common euryhaline cumacean from southern Brazil: Diastylis sympterygiae Bacescu & Queiroz, 1985 (Crustacea: Cumacea)

Diastylis sympterygiae Bacescu & Queiroz (1985) has been reported in many ecological studies conducted in the Patos Lagoon, southern Brazil. However, the original description of this species is based on damaged specimens from stomach contents of rays, and therefore insufficient for a confident identification. In the present contribution, based on a large number of well-preserved specimens now available from the type locality area, the description of this common euryhaline species is completed and its range of distribution as far north as Sao Paulo is extended.

Scrupocellaria (Bryozoa: Cheilostomata) from the Queensland coast, with the description of three new species

Among the Scrupocellaria species previously reported from Queensland, three are here redescribed - S. cervicornis, S. curvata and S. diadema; two other species, S. frondis and S. sinuosa, are recorded from the area for the first time; three new species, S. hamata n. sp., S. prolata n. sp. and S. peltata n. sp., are also described, and the remainder are discussed. The need for the re-examination of specimens assigned to this genus is highlighted. The geographic range of some Scrupocellaria species is far more limited than once thought.
