( Fig. 4 F-I) MATERIAL EXAMINED. — Madagascar . Analamazaostra, Andasibe, réserve de Périnet, XI.1952 , J. Arnoult,> 100 eggs (MNHN-Bp667). EGG MORPHOLOGY Numerous eggs were found in natural position under the carapace and at the bottom of the bottle. Eggs are oblong with long depressions.The bottom of the depression is narrow as well as the top of the ridges.The slopes of the depression are finely ornamented much like lace. At high magnification, the surface of the egg has small pores ( Fig. 4I ). Average mature maximum diameter is 185 µm (n = 4, SD = 3.36 µm ). REMARKS This species was stored in the MNHN under the name Limnadia sp. and was associated with an undetermined specimen of Lynceus , probably coming from the same collection. The egg morphology of this species is so distinctive and constant that this population should be described as a new species.
