is the presence of an enigmatic unpaired, spherical ampulla in XII – the function of which remains obscure. There is a possibility that this structure is used for storing sperm from a concopulant, which would imply that it is a spermatheca. However, the ampulla is surrounded by a cell cluster, which seems more glandular (prostate-like cells) than shaped in order to play the role of a bag for sperm storage. In this respect, such a structure is somewhat similar to the glandular, atrium-like organ in the pre-atrial segment of some

). Some material has been observed in the spherical ampulla but it does not resemble mature spermatozoa. Hence, the absence of spermathecae in this species seems plausible. Conversely, considering the ampulla and its surrounding cell cluster as an atrium and a prostate is another possibility – implying that the structures described above as ‘atria’ are in fact the spermathecae and the porophore is spermathecal. However, prostates seem to be absent in

, in a region lying on metamorphic bedrock. The ‘La Martinière’ gallery opens in the upper alteration layer of a crystalline craton, which forms granitic sand with scarce, particulate organic matter. A rivulet runs along the gallery and passes slowly through a thin layer of coarse sand. Historically (between 1846 and 1919) the Navogne gallery was dug in arkoses and ferruginous sandstone for iron ore exploitation. The water is present in the gallery as isolated puddles with gravelly soil, rich in organic matter.
