Bennelongia sp. nov. F2

Material investigated

Two ♀♀ ( KMWA.905, 906) in toto used for molecular screening, one ♀ with soft parts used for molecular screening and with broken RV stored dry in micropalaeontological cavity slide ( WAMC 52285 = KMWA.904).

Locality

Lilian Stokes Rocks (eastern Wheatbelt – BVT /10/09), coordinates: 33º4’06” S, 120º05’49” E. Collected on 25 Aug. 2010 by B. V. Timms.

Remarks

The specimens of the F2-group cluster close to those of B. ivanae sp. nov. in the phylogenetic tree ( Fig. 2 ), but still constitute a separate genetic species ( Table 2 ). A broken RV could be saved from only one of these specimens (KMWA.904), and it could be ascertained that the antero-ventral lapel on the RV is also fully absent (not shown). It is possible that cluster F2 will turn out to be a cryptic species within B. ivanae sp. nov., but this remains to be tested with new material. Note that the same sample (BVT/10/09) also contained one putative female of B. hirsuta sp. nov. (see above).

Figures

Fig. 2. Phylogenetic tree constructed with Bayesian Inference (BI) and Maximum Likelihood (ML) methods from COI sequences of 99 ostracods from the Bennelongia barangaroo lineage and with B. nimala as outgroup. Numbers above nodes illustrate statistical support for this particular node. Numbers before the hash (/) are % bootstrap values of ML analyses with 1000 replicates, numbers after the hash (/) are Bayesian posterior probabilities (ranging from 0 to 1). Both methods, BI and ML, resulted in the same tree topology. Different phylogenetic clades are indicated by different colours (as in Fig. 3, page 15). The asterisks indicate two nodes (α1 and α2) that are weakly supported (see Discussion, p. 55).
