Etymology: This large, distinctive species is named for the distinctive black and yellow body stripes (tigrinus, Latin, of tigers).

Diagnosis: Specimens of Atelomastix tigrina are large (body width greater than 2.5 mm, and length 42–61 mm) and, when alive, have a very striking colour pattern of black or dark brown with bright yellow-orange bands, similar to A. julianneae . This species can be distinguished by the distinctly angular shaped sclerite b and very elongate basal process that extends behind the main process of the male gonopod. Sclerite c is not bifurcate, is relatively straight, and shorter than sclerite b.

Description: Male (holotype). Colour ( Fig. 3 View FIGURES 1–3 ): live specimens with black to dark brown segments, head and legs with bright yellow-orange bands; prozonites dark brown, metazonites brown to bright yellow-orange in preserved specimens.

Body: ca. 56 mm long and ca. 3 mm wide at collum. With 65 trunk segments, 117 pairs of legs, last 2 segments without legs.

Head: with ca. 46 ocelli ( Fig. 73), arranged in 6 rows (3: 6: 7: 10: 8: 11).

Gonopods: anterior gonopods ( Figs. 132–135) heavily sclerotised, 2.7 times longer than broad; sclerite a with swollen base that forms broad, curved distal hood; upper distal face of sclerite a with 18–20 (n=3) short blunt setae; pseudoflagellum short, broad, and entirely visible on externo-lateral side of gonopod but not visible on interno-lateral side, where it is concealed within distal hood; sclerite b broad, angular, forming a blunt tip distally, with 4 erect setae (n=3) on sub-distal edge; basal process of sclerite b very long and elongate, 0.16 times the length of the main process; sclerite c shorter than sclerite b, not bifurcate, tapering to blunt tip, with 1–3 medial seta and 7–9 setae sub-distally on broad internal face (n=3); one sub-basal setae present where sclerites overlap and group of 13 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 (paratype male, WAM T74311): length ca. 56 (61), width ca. 3 (3), L/ W=18.7 (20.3); sclerite a 1.656 / 0.608 (1.704 / 0.694), setae 18 (20); sclerite b 0.701 (0.733), basal process of sclerite b 0.264 (0.288), setae 4 (4); sclerite c 1.088 (1.184), setae 1+9 (3+7).

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

Distribution and habitat: This species is only known from The Cascades at Bluff Knoll and the south face of Pyungoorup Peak in Stirling Range National Park ( Fig. 5 View FIGURES 4–6 ). The surrounding vegetation is dominated by sparsely growing jarrah ( Eucalyptus marginata ) and marri ( Corymbia calophylla ).
