Abstract
The freshwater crab Aegla expansa Jara, 1992 (Aeglidae) is endemic to Chile and has a geographical distribution restricted to one stream in the locality of Hualqui (37 degrees S), Concepcion Province, Chile. A chromosome number 2n = 154 is here described for somatic cells of A. expansa. The chromosomes are large in number and small in size (<2 mu m). These cytogenetic data are the first reported for a species of the genus Aegla.
