Morebilus gammon , new species Figures 367–370 ; Map 28

TYPES: Female holotype and male allotype taken under rock at Arcoon Creek, Gammon Ranges National Park , 30 ° 26 ̍ S, 138 ° 58 ̍ E, South Australia (May 5, 1989; D. Hirst), deposited in SAM ( N1999 /66, 67) .

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

DIAGNOSIS: Males can easily be recognized by the long, narrow, sinuous embolus (fig. 367) and prong­shaped retrolateral tibial apophysis (fig. 368), females by the rectan­ gular median plate in the epigynal atrium (fig. 369).

MALE: Total length 16. Coloration as in M. plagusius . Leg spination (legs II missing): femora: I d2­0­0; III d1­0­1; IV d2­0­1; tibiae: I v5­5­2; IV v1p­0­0; metatarsi: I v3­2­ 2; III v1p­1p­0. Retrolateral tibial apophysis strong, prong­shaped (fig. 368); embolus relatively long, narrow, sinuous, overlying prolateral portion of median apophysis (fig. 367).

FEMALE: Total length 19. Coloration as in M. graytown . Leg spination: tibiae: I v4­4­2; II v5­4­2; metatarsi: I v4­2­2; II v3­2­2; III v1p­1p­0; IV 1p­0­0. Epigynal atrium wide, with rectangular median plate (fig. 369); anterior spermathecal ducts v­shaped (fig. 370).

Figures 371–374 ; Map 28

TYPE: Female holotype from Coolah Valley , 31 ° 50 ̍ S, 149 ° 43 ̍ E, New South Wales (1935; J. Lecky), deposited in AMS (KS35546) .

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

DIAGNOSIS: Males can easily be recognized by the clump of stiff spines representing the retrolateral tibial apophysis (fig. 372) and the threadlike distal half of the embolus (fig. 371), females by the anteriorly pointed epigynal atrium (fig. 373) and the membranous anterior lobes on the spermathecae (fig. 374). MALE: Total length 12. Coloration as in M. graytown . Leg spination: femora: I–III d3­0­ 0; IV d2­0­0; tibiae: II v3­2­2; metatarsi II v2­1p­0. Retrolateral tibial apophysis reduced to patch of stiff spines (fig. 372); embolus abruptly narrowed, at about half its length, into threadlike structure (fig. 371).

FEMALE: Total length 14. Coloration as in male. Leg spination: femora: I, II d3­0­0; III d4­0­0; IV d2­0­0; tibiae: II v3­2­2; metatarsi: II v2­1p­0; III v2­0­0. Epigynal atrium angular anteriorly (fig. 373); spermathecae with pea­shaped, translucent anterior extensions and laterally directed heads (fig. 374).

OTHER MATERIAL EXAMINED: The single male here associated with the female was taken on Warrumbungle Mountain, 31 ° 15 ̍ S, 148 ° 59 ̍ E, New South Wales on Apr. 23, 1967 (C. Chadwick, AMS KS35506).
