Bennelongia kimberleyensis
Martens, Halse & Schön, 2012
Figs 13-15
The characteristic ‘pinged’ depression in the anterior region when seen dorsally is a feature of the ‘
Bennelongia
pinpi’
- lineage to which this species belongs (see discussion in
Martens
et al
. 2012
). The adult valves are smooth overall, and the A-4 and A-3 instars display a broad reticulation (best seen in A-4; see
Figs 13
bottom right, 14 bottom and 15) with some simple pores, that are best described as pseudo-pores in A-2 and A-1 instars.
A few cones with outer lips and setae are common in A-4 and decrease in number and size during the ontogenic progress (see
Figs 13-15
), but are absent in adults. The 2 sets of domes are obvious in A-4 and less so in A-3, but are absent in older instars and in the adults. When present, the domes are reticulated and are adorned with a seta.
