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°S), Concepción Province, Chile. A chromosome number is here described for somatic cells of A. expansa . The chromosomes are large in number and small in size (<2 μ m). These cytogenetic data are the first reported for a species of the genus Aegla .
