Figures 39–44

Material examined. Holotype: Tasmania, South Cape Rivulet , coastal scrub, 29 Mar 1988.

Description of female. Coloration (after ca 4.5 years in alcohol). Head dark brown, with the following brown: large patch on crest of vertex each side of median epicranial suture, broad band on vertex adjacent to epistomal suture extending across front of head to antennal socket, gena and antenna. Maxillary palps brown, terminal segment dark brown. Ocelli pale, centripetal margins black. Eyes black. Fore wing (fig. 39) brown, apex pale. Meso- and meta-thoracic terga with small dorsal median cream patch, remainder of thorax and legs brown. Abdomen cream, terminal segments brown.

Morphology. IO:D = 4.0. Head glossy. Postclypeal striae not obvious. Labrum: stylets small, spiculate; sensilla 5 in total; internal sclerotisation present. Lacinia (fig. 40) broad, preapically strongly expanded on one side, apical margin denticulate, strongly bent mid way. Antennal flagellar segments extremely short. Micropterous. Fore wing (fig. 39): vein cu 2 glabrous; apex narrowing; microtrichia on wing margin obvious, reduced at apical region of wing; anterior wing margin lacking setae. Hind wing a small rudiment. Presence of abdominal adhesive vesicles not known. Epiproct (fig. 41) setose. Paraproct (fig. 41) with small sclerotised cone and adjacent macroseta on posterior margin, a round field of 14 trichobothria. Subgenital plate (fig. 42) apically emarginate with lateral apophyses; posterior region bearing larger setae than remainder of plate; sclerotised pigment band with pair of anteriorly diverging arms. Gonapophyses (fig. 43) with external valve remnant represented by one seta. Spermatheca (fig. 44) with long glandular area, sac large and well sclerotised.

Male. Unknown.

Remarks. Known only from a single specimen, this species is distinctive in that vein cu 2 of the forewing is glabrous. In all other characters it agrees with Maoripsocus , and thus is tentatively placed here.

Etymology. Named for Sir John L. Pedder, the first Chief Justice of Tasmania.
