Etymology:
The specific epithet is a patronym in honour of Mike Bamford who has collected other species of
Atelomastix
in
Western Australia
.
Diagnosis:
Atelomastix bamfordi
differs from other species by the short, broad distal end of sclerite
c
. Also, sclerite
b
is much longer than sclerite
c
, is relatively broad and short, curved sub-distally, and tapers slightly to form a very small pointed tip. The distal hood of sclerite
a
is very broad and extends past the tip of sclerite
b
and
c
and almost entirely obscures the short pseudoflagellum.
Description:
Male (
holotype
).
Colour: generally yellow-brown, legs brown, gonopods golden brown; prozonites mottled chocolate brown, metazonites mottled chocolate brown in preserved specimens.
Body: ca.
33 mm
long and ca.
2.2 mm
wide at collum. With 53 trunk segments, 95 pairs of legs, last 2 segments without legs.
Head: with ca. 48 ocelli (
Fig. 51
), arranged in 6 rows (4: 7: 9: 10: 11: 7).
Gonopods: anterior gonopods (
Figs. 81, 82
) with light to medium sclerotisation, 2.2 times longer than broad; sclerite
a
with swollen base that forms very broad, curved distal hood that extends beyond tip of sclerite
b
; upper distal face of sclerite
a
with 24 short blunt setae; pseudoflagellum relatively short and almost entirely obscured beneath broad distal hood; sclerite
b
broad, curved sub-distally, slightly tapering to form a very small pointed tip, with 9 short setae; basal process of sclerite
b
short, 0.04 times length of main process; sclerite
c
much shorter than sclerite
b
, without concavity, but indented slightly sub-distally, with broadened distal tip, with 5 setae near indentation; sub-basal setae not visible where sclerites overlap and group of 11 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: length ca. 33, width ca. 2.2, L/W=15.0; sclerite
a
1.288
/
0.589
, setae 24; sclerite
b
0.443, basal process of sclerite
b
0.035, setae 9; sclerite
c
0.867, setae 5.
Female
. Similar to male, other than sexual characters, and slightly larger.
Distribution and habitat:
This species occurs at several locations in the central wheatbelt region of
Western Australia
(
Fig. 4
), including the Koolyanobbing and Windarling Ranges, Marvel Loch, and Mt Jackson. The specimens were found in or under leaf litter, in soil or under stones.
