ETYMOLOGY: The specific name is an arbitrary combination of letters.
DIAGNOSIS: This aberrant species (and its hypothesized sister taxon,
N. blackall
,
new species
) are easily distinguished from all oth er
Notsodipus
by the very small size and very narrow abdomen. Males have a uniquely developed tegular lobe (figs. 702, 703); females of both have a distinctively elongat ed epigynum (figs. 592, 704) that nevertheless has the posteriorly directed duct extensions found in other species of the genus; in
N. visio
, the median ducts are much shorter than in
N. blackall
(fig. 705).
MALE: Total length 1.8. Abdominal dorsum long, narrow, dark gray with scattered white hairlines under full scutum, venter pale white with large rectangular orange scutum covering most of surface behind epigastric furrow. Legs without spines. Retrolateral tibial apophysis incised at tip (fig. 703); tegular knob enormously enlarged into distinctive apophysis (fig. 702).
FEMALE: Total length 1.9. Coloration as in male except dorsal and ventral abdominal scuta absent. Legs without spines. Epigynum long, atrium situated anteriorly, with two anterior hoods (fig. 704); median ducts relatively short, with short, posteriorly directed extensions (fig. 705).

DISTRIBUTION: Despite the large geographic gap between them, I’ve found no characters by which to distinguish the South Australian male from those known from southwestern
Australia
(map 78).
