Types. Holotype female: AMS KS4509 , 6.5km south of Coulta, Eyre Peninsula , South Australia, 34°23'S 135°28'E, 18 December 1952, B.Y. Main.

Diagnosis. CL 6.6 (female). Small atracine spiders. Differs from other adelaidensis group species by its rather uniform maroon-brown abdominal pigmentation (much lighter laterally and ventrally in other species). Prolateral patella with 5–10 spines. Spermathecae unmodified, sac-like.

Distribution. Southern Eyre Peninsula, South Australia ( Fig. 105 ).

Comments. This species represents the known western extent of the atracine spiders in Australia. maxilla; (B) cephalothorax and chelicerae, lateral; (C) cheliceral groove teeth; (D) spinnerets; (E) cephalothorax and chelicerae,

ACKNOWLEDGMENTS. The late Vera Levitt-Gregg was a Sydney naturalist and Australian Museum Associate, whose knowledge and enthusiasm initiated my interest in these highly venomous spiders. My thanks to Dr Robert Raven for his useful comments on the manuscript. Curatorial staff at the Queensland Museum, Museum Victoria, the Tasmanian Museum and Art Gallery, the Launceston Museum and Art Gallery and the South Australian Museum assisted with the loan of material. Field work was supported by a grant from the Australian Biological Research Study—thanks to Harry Parnaby for his field assistance. Funding from the Australian Museum assisted with mapping and SEM editing work by Vicky Tzsoumiz. Sue Lindsay took the SEM pictures and Kate Attwood kindly assisted with re-arrangement of drawings. Thanks to my wife, Greta Jensen Gray, who assisted in so many ways, including data compilation, field work and coffee.

Morphological characters and measurement points

A Palpal organ. (1) Bulb length—tegulum+embolus. (2) Bulb width—across tegulum and subtegulum. (3) Embolus length. (4) Embolus mid-width. (5) Offset of basal embolus from tegulum. (6) Twisted and “flanged” distal part of embolus.

B Cheliceral tooth row: length and mid-width.

C Carapace, dorsal: length, width and clypeal frontal width.

D Labium: length, width. Sternum: length, width. (Note: the presence of setae on the posterior labium helps differentiate it from the smooth hairless cuticle of the labiosternal sigillum

E Leg segment lengths: femur, patella, tibia, metatarsus, tarsus.

F Posterior lateral spinnerets, apical segment: length and mid-width.

G Male palpal tibia: length, width.

H Carapace, lateral: height.

List of atracine spider species, with numbers previously allocated to new species. Undescribed species dealt with in Gray (1986, 1987, 1988) were identified by species numbers. These numbers are given below with the corresponding new species names allocated here. Note that number 5 in the Hadronyche species number list is intentionally omitted.
