Figs. 8 View FIGURES 7–9 , 69, 122–124.

Type material: AUSTRALIA: Western Australia: holotype male, Kangawarie clearing, ca. 50 km NW. of Israelite Bay , hut area, 33°13’36”S, 123°38’16”E, hand collected in leaf litter, 7 August 2004, A.F. Longbottom ( WAM T 72121) GoogleMaps . Paratype: 1 female, collected with holotype ( WAM T 72122) GoogleMaps .

Etymology: This species is named for the serrate or saw-shaped distal edge of the male gonopod sclerite b (prionos, Greek, saw).

Diagnosis: Atelomastix priona can be distinguished from other species by the distinctive serrated, or sawlike distal edge of sclerite b. In addition, sclerite c is not bifurcate, has a concavity on the interno-lateral side of the gonopod, is distally tapering and curved, and the distal edge is similar in height to sclerite b.

Description: Male (holotype). Colour: head, collum, anal segment, antennae, and anal valves dark brown, legs and gonopod light brown; prozonites mottled chocolate brown, metazonites dark brown to golden brown in preserved specimen.

Body: ca. 42 mm long and ca. 2.6 mm wide at collum. With 61 trunk segments, 111 pairs of legs, last 2 segments without legs.

Head: with ca. 53 ocelli ( Fig. 69), arranged in 6 rows (6: 7: 9: 10: 10: 11).

Gonopods: anterior gonopods ( Figs. 122–124) lightly sclerotised, 2.4 times longer than broad; sclerite a with swollen base that forms broad, curved distal hood; upper distal face of sclerite a with 23 short blunt setae; pseudoflagellum relatively short and partially visible beneath distal hood; sclerite b broad, slightly curved distally, distal edge serrate like saw, with 16 short setae; basal process of sclerite b small short, 0.03 times length of main process; sclerite c same height as sclerite b, slightly bifurcate, lateral process long, thin, slightly curved distally, medial process very small, triangular, with 3 setae between lateral and medial processes; sub-basal setae absent where sclerites overlap and group of 20 short setae sub-basally on sclerite c; posterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod.

Dimensions (mm): holotype male: length ca. 42, width ca. 2.6 (L/W=16.4); sclerite a 1.544/0.64, setae 23; sclerite b 0.497, basal process of sclerite b 0.045, setae 16; sclerite c 1.00, setae 3.

Female. Similar to male, other than sexual characters, and slightly larger.

Distribution and habitat: This species is only known from one male and one female collected from Kangawarie clearing, about 50 km northwest of Israelite Bay ( Fig. 8 View FIGURES 7–9 ).
