Bennelongia sp. nov. E2

Fig. 25 E-H

Material investigated

One dissected ♀ (nr KMWA.806), with soft parts used for molecular analysis and valves stored dry in a micropalaeontological cavity slide.

Locality

Yakabindie Claypan, approximately 27°34’ S, 120°31’ E (sample LN3006), collected by Outback Ecology on 24 Mar. 2011.

Morphology and affinities

Although general valve appearance again shows some affinities to B. scanloni sp. nov., the different shape of the antero-ventral il on the LV (less pronounced and evenly rounded) and the large and subquadrate anteroventral lapel on the RV distinguishes this specimen from all other species (re-)described here. Molecular analysis of the soft parts of the same specimen shows that it clusters outside of the B. scanloni sp. nov. group (including cryptic species B2 and E1), and constitutes a different genetic species. Lack of additional material and males prevents us from formally describing this new species here.
