Etymology: This species is named for its yellow mouth region (flavus, Latin, yellow; gnathos, Greek, jaw).

Diagnosis: This species is characterised by distinctive bright yellow mouthparts and legs. Sclerite b of the male gonopods is elongate, curved downwards, with a pointed distal tip, extending past the edge of sclerite c. Sclerite c is distally bifurcate with lateral and medial processes of similar lengths.

Description: Male (holotype). Colour: legs and mouthparts bright yellow; collum, head, anal segment, ozopores, and antennae dark brown; prozonites pale golden-brown, metazonites pale blue-grey in preserved specimens.

Body: ca. 27 mm long and ca. 1.8 mm wide at collum. With 50 trunk segments, 89 pairs of legs, last 2 segments without legs.

Head: with ca. 43 ocelli ( Fig. 57 View FIGURES 48–59 ), arranged in 6 rows (4: 5: 7: 8: 9: 10).

Gonopods: anterior gonopods ( Figs. 94–97) lightly sclerotised, 2.65 times longer than broad; sclerite a with swollen base and broad, curved distal hood; upper distal face of sclerite a with 15–20 (n=2) short blunt setae; pseudoflagellum elongate and visible beneath broadened distal hood; sclerite b relatively long and curved, terminating in an elongate rounded hook, with 11–14 (n=2) distally serrate extending to sub-distal end of sclerite; basal process of sclerite b broad with blunt tip, 0.30 times length of main process; sclerite c same height as sclerite b, shallowly bifurcate, lateral and medial processes of similar length and relatively widely separated, with 3–4 setae (n=6) on internal face; 1 sub-basal setae where sclerites overlap and group of 11–12 (n=2) 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 T47937): length ca. 27 (22), width ca. 1.8 (1.6), L/W=15 (14); sclerite a 1.258 / 0.474 (1.197 / 0.464), setae 20 (15); sclerite b 0.474 (0.474), basal process of sclerite b 0.022 (0.042), setae 14 (11); sclerite c 0.864 (0.885), lateral process of sclerite c 0.064 (0.109), medial process of sclerite c 0.058 (0.032), setae 3 (4).

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

Distribution and habitat: This species can be found at a number of sites in the Fitzgerald River National Park ( Fig. 7 View FIGURES 7–9 ), where they were mostly found under rocks in mallee heath or Melaleuca, Eucalypt woodlands.
