Notsodipus dalby , new species Figures 650–653 ; Map 73

TYPES: Female holotype and male allotype taken in pitfall traps at Lake Broadwater, via Dalby, Queensland, 278219S, 1518069E, (May 16–Nov. 23, 1985), deposited in QMB ( S28523 ).

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

DIAGNOSIS: This species closely resembles N. innot (see below), but can be distinguished by the shorter embolus and smaller terminal apophysis (fig. 650) of males and by having the posteromedian epigynal ducts largely overlain by the posterolateral ducts (fig. 653) in females.

MALE: Total length 3.5. Abdominal dorsum with two pairs of lighter muscle impressions visible under dark scutum; venter gray, with anterior pair of circular orange sclerites and large, rectangular, median, orange sclerite. Leg spination: tibia III v0­0­0. Retrolateral tibial apophysis long, smoothly tapered (fig. 651); terminal apophysis with distally narrow median prong, distal elements relatively short, narrow, embolus relatively short, not reaching to ventral edge of bulb (fig. 650).

FEMALE: Total length 2.6. Abdominal dorsum gray, with two pairs of lighter muscles impressions and several thin, narrow, posterior pale chevrons; venter without sclerites, with two oblique rows of pale spots. Leg spination typical for genus. Epigynal atrium almost rectangular (fig. 652); spermathecae ductlike, widely separated anteriorly, with lateral ducts fully overlying their lateral ends (fig. 653).
