Diagnosis
. Male palp (
Figs 20a–b
) with TA consisting of two short, blunt tipped projections. MA with elongate proximal projection curving prolaterally and expanding to paddle shaped tip and with narrow, elongate prolateral projection. Embolus simple, broad at base with small basal expansion and narrow tip. Palpal patella with one dorsal spine, palpal tibia without spines. Female epigynum unknown. Tarsal organ capsulate, situated distally of trichobothria.
Description
.
Male

Storenosoma picadilly
. (a–b)
male palp (ANIC, ACT, Wombat Ck., 6 km
NE of Picadilly Circus):
(a)
ventral;
(b)
RTA, retrolateral. Scale line 0.25 mm.
Etymology
. The specific name is a noun in apposition taken from the
type
locality.
Distribution
. Known only from the vicinity of the
type
locality in the ACT and Newnes SF in NSW (
Fig. 27c
).
Remarks
. The
two female
specimens attributed to this species have their epigyna plugged making the morphology unclear. For this reason the epigynum has not been illustrated. However, following the law of parsimony they have been attributed to
S. picadilly
, the only known sympatric species of similar size.
