Notsodipus magdala , new species Figures 670–673 ; Map 75

TYPE: Male holotype from East Magdala Woodland, Jabiru , 148589S, 1348079E, Northern Territory (Apr. 2, 1982; Morton), deposited in SAM ( N1997 /103) .

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

DIAGNOSIS: This species resembles N. marun in having a folded median prong of the terminal apophysis of the male palp and a relatively large epigynal atrium. Males can be distinguished by the shape of the lateral prong of the terminal apophysis (fig. 670), females by the wide epigynal septum (fig. 672).

MALE: Total length 4.0. Abdominal dorsum with large pair of pale, anterior spots and few pale posterior chevrons showing through scutum, venter with weak, narrow, rectangular orange sclerite overlaying two longitudinal rows of small, orange, circular sclerites. Leg spination typical for genus. Retrolateral tibial apophysis long, narrowed distally and subbasally (fig. 671); median prong of terminal apophysis sharply curved near base, distally folded, lateral prong with three cusps (fig. 670).

FEMALE: Total length 3.6. Coloration as in male except venter without rectangular scler­ ite. Leg spination typical for genus. Epigynal atrium large, occupying about half of epigynal length, with wide median septum (fig. 672); median spermathecal ducts well separated throughout most of their length (fig. 673).
