Diagnosis
.
Artoriopsis murphyi
sp. nov.
is very similar to
A. eccentrica
Framenau, 2007
, but differs in details of the male genitalia, in particular the shape of the tegular apophysis. This is bent dorsally into the cymbium in
A. eccentrica
, but not so in
A. murphyi
sp. nov.
The profile of the tegular apophysis in retrolateral view is also less pronounced in
A. murphyi
sp. nov.
Description
. Male (based on
holotype
, QVM:2020:13:0303).
Prosoma, dorsal shield (
Fig. 5A
). Dorsal profile in lateral view straight; dark reddish-brown, with light median and lighter lateral bands; dense white setae lateral bands and flanks of head, less dense otherwise; two bristles below AE and few bristles between eyes.
Eyes. Row of AE procurved, narrower than row of PME.
Sternum (
Fig. 5B
). Very dark brown, shiny; black bristles that are longer and denser towards margins.
Labium. Dark brown, shiny; front end truncated and white.
Chelicerae. Dark reddish-brown, with black macrosetae; three promarginal teeth, the median largest; three retromarginal teeth of almost equal size.
Legs. Leg formula IV>I>II>III; yellow-brown with dark annulations; femora of leg VI somewhat lighter centrally.
Pedipalp (
Fig. 5C,D
). Tegular apophysis elongate, flat and broad; narrowing distally and ending broadly truncated in ventral view (
Fig. 5C
); embolus strong, terminal apophysis heavily sclerotized and tip twisted (
Fig. 5C
).
Opisthosoma (
Fig. 5A,B
). Typical
Artoriopsis
-pattern, i.e. black diamond-shaped mark centrally that is cut through by light lanceolate cardiac mark; posteriorly with rectangular light patch. Venter yellow-brown, mottled dark. Spinnerets brown.
Measurements. TL 5.2, PL 2.7, PW 1.9. Eyes: AME 0.09, ALE 0.07, PME 0.29, PLE 0.18. Row of eyes: AE 0.52, PME 0.70, PLE 0.79. Sternum (length/width) 1.30/0.98. Labium (length/width) 0.41/0.36. OL 2.4, OW 1.6. Legs: Lengths of segments (femur + patella + tibia + metatarsus + tarsus = total length): Pedipalp 0.85 + 0.40 + 0.40 + — + 0.90 = 2.55, I 1.60 + 0.80 + 1.15 + 1.20 + 0.85 = 5.60, II 1.55 + 0.75 + 1.10 + 0.90 + 0.75 = 5.05, III 1.35 + 0.70 + 0.90 + 1.05 + 0.65 = 4.65, IV 2.20 + 0.85 + 1.40 + 1.85 + 0.85 = 7.15.
Female unknown.
Etymology
. The specific epithet is a patronym for Murphy Widdowson, the then ten year old son of Jo and Justin Widdowson, who collected the specimen while staying on Deal Island in Bass Strait. His father, Justin, was seconded there from June to August, 2020, as part of his role as ranger with Tasmanian Parks and Wildlife Service. Jo and Murphy accompanied Justin to the island and as Murphy had to be home-schooled, they tried to combine a mix of indoor theory with outside practical studies. Several sampling trips were undertaken aiming for a variety of species and sampling locations each time.
