Etymology: The specific epithet is a patronym in honour of Patrick Cullen.

Diagnosis: The male gonopod morphology of Atelomastix culleni is similar to A. psittacina as sclerite a has a broad distal hood that curves around to overlap sclerite b and obscure the pseudoflagellum. However, it can be distinguished from A. psittacina as sclerite b is not significantly curved into a distal hook, and sclerite c is straight and broadened distally with a shallow concavity directed laterally.

Description: Male (holotype). Colour: generally chocolate brown; legs, anal segment and antennae light brown; prozonites mottled brown, metazonites mottled brown in preserved specimens.

Body: ca. 24 mm long and ca. 1.8 mm wide at collum. With 47 trunk segments, 81 pairs of legs, last 3 segments without legs.

Head: with ca. 38 ocelli ( Fig. 53 View FIGURES 48–59 ), arranged in 6 rows (2: 5: 5: 8: 8: 10).

Gonopods: anterior gonopods ( Figs. 85, 86) with medium sclerotisation, 2.2 times longer than broad; sclerite a with swollen base that forms broad, curved distal hood that overlaps and extends to tip of sclerite b; upper distal face of sclerite a with 21–38 (n=2) short blunt setae; pseudoflagellum relatively short and partially visible beneath distal hood; sclerite b curved distally, forming blunt elongate tip, with 8–14 (n=2) short setae; basal process of sclerite b short, triangular, 0.08 times length of main process; sclerite c shorter than sclerite b, not bifurcate, tapering slightly to broad tip, 4–6 setae sub-medially; sub-basal setae absent where sclerites overlap and group of 11–14 (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 T78621): length ca. 24, width ca. 1.8, L/W=13.2; sclerite a 1.216 / 0.543 (1.520 / 0.720), setae 21 (38); sclerite b 0.458 (0.512), basal process of sclerite b 0.038 (0.038), setae 8 (14); sclerite c 0.768 (0.960), setae 4 (6).

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

Distribution and habitat: Atelomastix culleni is only known from Bremer Bay and Mount Groper ( Fig. 7 View FIGURES 7–9 ). Specimens were collected from leaf litter taken from forested gullies dominated by Eucalyptus , Melaleuca and Agonis .
