Bennelongia sp. X1

Fig. 24 A-D

Material investigated

One dissected ♀ (nr OS.255), with soft parts in a sealed slide and valves stored dry in a micropalaeontological cavity slide.

Locality

Canegrass covered claypan beside North-West Coastal Highway on Wooramel Station ( CB 35a), 25°40’52” S, 114°13’14” E, collected by S. Halse and A. Clarke on 24 Aug. 1994.

Morphology and affinities

The specimen is characterised by (1) a large antero-ventral lapel on the RV, subquadrate and only weakly crenulated, i.e., a shape unlike that of any of the other species (re-) described in the present paper, (2) a relatively small antero-ventral il on the LV and, (3) the bluntly pointed posterior margin of the LV, with a pronounced flange. The latter character is unique within the B. barangaroo lineage. If this character is stable and also occurs in other specimens, it could be indicative at a specific level.
