Type material: AUSTRALIA: Western Australia: holotype male, Eyre Range, Fitzgerald River National Park , unburnt gully, 33°50’50”S, 119°57’07”E, hand collected under rock, 30 May 2007, M.L. Moir, M.C. Leng ( WAM T 80799) GoogleMaps .

Other material examined: AUSTRALIA: Western Australia: 1 female, Eyre Range, Fitzgerald River National Park , unburnt rock outcrop, 33°51’50”S, 119°57’32”E, hand collected under rock, 30 May 2007, M.L. Moir, M.C. Leng ( WAM T 80800) GoogleMaps .

Etymology: The specific epithet is a patronym in honour of Frances Leng who collected the holotype and numerous other species of Atelomastix in southwestern Australia.

Diagnosis: Atelomastix lengae differs from all other species as the male gonopod sclerite c is barely distally bifurcate, and is generally straight and slightly broadened distally. It has a broad sclerite b that does not extend to sclerite c and tapers gently to a broad tip distally.

Description: Male (holotype). Colour: generally dark brown; legs, antennae, mouthparts, lighter brown with distinctly light bands; prozonites dark brown; metazonites dark brown to very pale in preserved specimens.

Body: ca. 42 mm long and ca. 2.4 mm wide at collum. With 67 trunk segments, 123 pairs of legs, last 2 segments without legs.

Head: with ca. 52 ocelli ( Fig. 62), arranged in 7 rows (4: 5: 6: 7: 9: 10: 11).

Gonopods: anterior gonopods ( Figs. 106, 107) with light to medium sclerotisation, 2.3 times longer than broad; sclerite a with swollen base that forms broad, curved distal hood; upper distal face of sclerite a with 52 short blunt setae; pseudoflagellum relatively short and partially visible beneath broad distal hood; sclerite b broad, tapers gently to a broad distal tip that does not extend to sclerite c, with 7 short setae; basal process of sclerite b very short, 0.01 times length of main process; sclerite c about same height as sclerite b, slightly concave on internal surface, with slight indent sub-distally and slightly broadened distally to a very shallow bifurcated tip, with 4 setae; sub-basal setae not visible where sclerites overlap and group of 11 short setae subbasally on sclerite c; anterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod.

Dimensions (mm): holotype male: length ca. 42, width ca. 2.4, L/W=17.5; sclerite a 1.44/0.634, setae 52; sclerite b 0.506, basal process of sclerite b 0.014, setae 7; sclerite c 1.024, setae 4.

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 from an unburnt gully in the Eyre range, Fitzgerald River National Park ( Fig. 9 View FIGURES 7–9 ). These two specimens were found under rocks.
