Notsodipus muckera , new species Figures 662–665 ; Map 74

TYPES: Female holotype and male allotype taken in pitfall traps at Muckera , 308029S, 1308039E, South Australia (Sept. 1984; B. Guerin), deposited in SAM ( N1996 /349, 350) .

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Males can be recognized by the long, arched median prong of the terminal apophysis, which is abruptly narrowed near its tip (fig. 662), females by the relatively long median and highly coiled lateral epigynal ducts (fig. 665).

MALE: Total length 3.8. Abdominal dorsum apparently uniformly gray under scutum, venter with four longitudinal rows of small, circular, orange sclerites largely overlain by large, rectangular orange sclerite. Leg spination typical for genus. Retrolateral tibial apophysis very long, narrow (fig. 663); median prong of terminal apophysis long, accompanied for most of its length by membranous lobe, distal elements very large, smoothly arched (fig. 662).

FEMALE: Total length 4.6. Abdominal dorsum mottled gray, venter with two parame­ dian longitudinal rows of small, brownish sclerites. Leg spination typical for genus. Epigynal atrium relatively shallow, divided for most of its length (fig. 664); median epigynal ducts very long, accompanied by highly coiled lateral ducts (fig. 665).
