Figs 8 A–G
Abbreviated description
Valves in inner view (Fig. 8A, C) relatively elongated, with rounded dorsal margin and greatest height situated slightly in front of the middle; ventral margin anteriorly without pronounced mandibular curve. LV (Fig. 8A) with antero-distal il running over halfway along the anterior valve margin, antero-proximal il running about 4/5 way up along the anterior valve margin; posterior il tuberculate, but more delicately so than in the preceding three species, and running halfway up the posterior margin. RV (Fig. 8C) with antero-ventral lapel pronounced and rounded but with a smooth edge (Fig. 8 F–G). Valves with external ornamentation mostly consisting of small tubercles, less pronounced than in the three preceding species (Fig. 8 C–E).
Cp (Fig. 8 C–E) with large LV/RV overlap, but less so than in the two preceding species. CpD and CpV with greatest width situated in the middle in females, anteriorly with strong and asymmetrical rostrum.
Soft parts as typical of the genus.
Male unknown.
Etymology
The species is named after Adrian M. Pinder (DPaW, Science and Conservation Division, Kensington, WA) in recognition of his substantial contribution to our knowledge about the taxonomy and ecology of freshwater invertebrates of Australia, especially freshwater Oligochaeta.
Type material
Holotype
♀ (WAMC55620), valves stored dry in a micropalaeontological slide and soft parts used for molecular screening.
Paratypes
Numerous females from the type locality, either stored as the holotype, as carapaces used for SEM or in alcohol (WAMC 55621–55623, OC3378). See Table 1 for listing of specimens.
Other material investigated
Unnamed claypan near Murchison River, Murchison, WA (sample SIKE 01).Approximate coordinates: 27°50’03” S, 114°43’37” E. All material was collected by the authors on 5 Jul. 2011. K25 = 28 µS/cm, Temp = 8.3°C, pH = 5.8.
Roadside ditch on Euardy Station, Murchison, WA (sample SIKE 05). Approximate coordinates: 27°35’31” S, 114°41’43” E. All material was collected by the authors on 5 Jul. 2011. Several females (WAMC 55624–55625). K25 = 31 µS/cm, Temp = 14°C, pH = 6.7.
Type locality
AUSTRALIA: Unnamed swamp, Coolcalalaya Station, Murchison, WA (samples CB06a, SIKE 3). Approximate coordinates: 27°31’22” S, 115°04’23” E. All material collected by the authors on 5 Jul. 2011. K25 = 33 µS/cm, Temp = 13.6°C, pH = 7.8.
Measurements (all measurements in µm – see Table 1 for measurements of all specimens illustrated with SEM)
Holotype ♀ (WAMC55620): RV: L = 1395, H = 810; LV: L = 1507, H = 840.
Differential diagnosis
Bennelongia pinderi sp. nov. is most closely related to B. koendersae sp. nov., but is ca. 15–20% larger, has a less pronounced valve ornamentation and has a less-developed antero-ventral lapel with a smooth edge on the RV rather than serrated as in B. koendersae sp. nov.
Ecology and distribution
Bennelongia pinderi sp. nov. has thus far been found in three seasonal or ephemeral water bodies in the Murchison region of WA.
