Etymology: The specific epithet is a patronym in honour of Carl Graf Attems, who described the genus Atelomastix in 1911.

Diagnosis: This species is similar to Atelomastix mainae , but differs in the shape and size of lateral and medial processes of sclerite c, the shape of sclerite b, the shape of the basal process of sclerite b, and the absence of a sub-basal seta. In A. attemsi the lateral and medial processes are broad and relatively symmetrical compared to A. mainae . Also, sclerite b is relatively much thinner, with distinct curvature, and well developed setae at the sub-distal end. The basal process of this sclerite is thinner and longer than the process seen in A. mainae .

Description: Male (holotype). Colour: Collum and anal segment dark brown; head, mouth parts, antennae, gonopod, ozopores and legs golden-brown; prozonites blue-grey, metazonites pale golden brown.

Body: ca. 17 mm long and ca. 1.3 mm wide at collum. With 41 trunk segments, 67 pairs of legs, last 4 segments without legs.

Head: with ca. 16 ocelli ( Fig. 50 View FIGURES 48–59 ), arranged in 4 rows (1: 3: 5: 7).

Gonopods: anterior gonopods ( Figs. 79, 80) large and complex in structure, 2.60 times longer than broad; sclerite a with swollen base and broad, curved distal hood; upper distal face of sclerite a with 20 short blunt setae; pseudoflagellum short, broad, and partially concealed within broadened distal hood; sclerite b elongate, curving to rounded hook at distal end, not extending to edge of sclerite c, with 3–7 relatively large setae on subdistal edge (n=3); basal process of sclerite b very long, tapering to narrow rounded end, 0.23 times length of main process; sclerite c bifurcate, same height as sclerite b, lateral and medial processes symmetrical, each tapering to blunt rounded tip, with 4–5 setae (n=3) positioned below division of lateral and medial processes; without sub-basal seta on sclerite c; posterior gonopods inconspicuous, small, with several small setae on interno-lateral face of each gonopod.

Dimensions (mm): holotype male (paratype male, WAM T69747): length ca. 17, width ca. 1.3 (L/ W=13.1); sclerite a 0.883 / 0.340 (0.966 / 0.442), setae 20; sclerite b 0.366 (0.429), basal process of sclerite b 0.085 (0.070), setae 3 (5); sclerite c 0.586 (0.648), lateral process of sclerite c 0.103 (0.120), medial process of sclerite c 0.104 (0.108), setae 4 (5).

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

Distribution and habitat: This species is only known from three sites in the Porongurup Range National Park, situated approximately 34 km north of Albany ( Fig. 6 View FIGURES 4–6 ). The dominant vegetation in this area includes tall karri ( Eucalyptus diversicolor ) forests and mixed karri, jarrah ( E. marginata ) and marri ( Corymbia calophylla ) forests. Specimens were collected by hand from under rotting logs. This species occurs with A. julianneae , although the level of sympatry is not currently known.
