Nuevas aportaciones al conocimiento de macroinvertebrados de agua dulce de Costa Rica y Nicaragua, con especial énfasis en las esponjas

Abstract

The characterization of 30 temporary ponds was done in the tropical dry forest of Costa Rica and Nicaragua, in 2010-2011. Gemmules of sponges were isolated in four of the studied sites. Two new records were set for Nicaragua, Radiospongilla cerebellata (Bowerbank, 1863) and Corvoheteromeyenia heterosclera (Ezcurra de Drago, 1974). In Costa Rica, the last ones was also recorded as well as specimens of Radiospongilla crateriformis (Potts, 1882) were collected. In another pond of Costa Rica, larva of Neuroptera (Insecta) belonging to family Sisyridae, commonly associated to sponges, was collected: Sisyra apicalis Banks, 1908. In addition, we have been able to collect embedded gemmules in the housing tube of the annelid Aulophorus vagus Leidy, 1880 (Annelida: Oligochaeta: Naididae). This species is also here reported for the first time in Costa Rica and Nicaragua.
