Oedemaperla shackletoni , sp. nov.

( Fig. 34 A–E)

Holotype: 1 x larva: Atherton Tablelands , Queensland . Collected May-2011, Collectors: M. Shackleton & J. Mynott, Accession number: JMH1693. Deposited in ANIC

Adult: unknown.

Larva. Remarks. Part of a genetic grouping of three species with two species partially identified as Oedemaperla cardaleae (O. cf cardaleae and O. sp NQLD3). The morphological distinction between O. sp NQLD3 and O. shackletoni provide sufficient evidence that this is a new species.

Material examined: Queensland: 1 x larva: Babinda Creek at The Boulders. -17.34235, 145.86901. Collected: 6-May-11, Collectors: M Shackleton & J Mynott, Accession number: JMH1373 . 3 x larvae: 16km on Davies Creek Road, East of Mareeba QLD ( Brindle Creek ) . -16.97609, 145.54569. Collected: 18-Jun-71, Collectors: EF Riek (housed in ANIC).

Length: 4.6 mm.

Colour: Brown. Pale patches central area of tergite X.

Body: Robust. Tubercules on thorax.

Head: Robust setae tapering to a point on dorsal surface of head. Antennae as long as body.

Thorax: Pronotum not wider than head and quadrate; anterior margin straight, posterior margin convex. Slightly raised area in centre of each pronotal division. Surface of pronotum with robust setae tapering to a point, dark obvious sockets (look similar to tubercles but with setae). Meso- and meta-nota with raised bosses and with raised area in medial area. Hind margin of meso- and meta-nota with sickle shaped robust setae, rest of notal setae similar to pronotum.

Legs: Femora and tibia with fringe of long fine setae. Outer surface of femora and tibiae with long robust setae present. Outer margin of femora with a couple of very long robust setae present. Hind margin of femora with dorsal spur present, upper distal corner with dense robust setae present. Femora with weak broad dark band present in distal area, tibiae with narrow dark band in proximal area, weak longitudinal stripe on outer surface of tibiae.

Abdomen: Tergites with robust setae tapering to a point, hind margins similar to those on the surface. Tergite X with similar setae to other segments, white patches in posterior area darkening near hind margin; hind margin produced to a small rounded knob. Purplish gills. Cercal segment length greater than width by segment 7–8; long robust setae on margins of cercal segments until 11th segment. Paraproct length approximately same as basal width.

Etymology: Dedicated to Michael Shackleton who assisted on many of the collection trips.
