Eulimnadia magdalensis Roessler, 1990: 596, figs 1-10. — Roessler 1995: 254, figs 1c, 2c, 3c, 4a,c, 5. — Pereira & Garcia 2001: 646, figs 5, 9E.

TYPE LOCALITY. — Natagaima in Tolima department, Colombia (Roessler 1990).

MATERIAL EXAMINED. — Cambodia. “Cochinchina” “Marais d’Angkor”, 1875, Harmand,> 10 eggs (MNHN-Bp325) ;> 10 eggs (MNHN-Bp328) .

RANGE. — Present in relatively humid tropical climate in various place in Colombia (Roessler 1990, 1995), Venezuela (Pereira & Garcia 2001), Brazil (unpublished data) and following this study in Cambodia.

EGG MORPHOLOGY

Spherical and ornamented by large pentagonal or hexagonal depressions with a flat bottom and narrow high ridges. Ridge intersections bear a spiniform projection. Average matureegg diameter is 183.4 µm (n = 5, SD = 4.8 µm).

REMARKS

This population from Cambodia was initially determinated as E. compressa by Daday de Deés (1926) but the eggs are identical to South American populations of E. magdalensis described from Colombia (Roessler 1990, 1995) and more recently found in Venezuela (Pereira & Garcia 2001). Following Sars (1896, 1900) and Daday de Deés (1926) the same egg type is also suspected for E. dahli, E. similis and E. garreti suggesting a possible synonymy with E. magdalensis but they need to be re-examined with modern procedures.
