description: Cryptachaea gigantipes (Keyserling, 1890) new combination
(Figs 2–15, 17–20, 21)
Theridion gigantipes — Keyserling, 1890: 245 –246, pl. 22, figs 4, 4a; Hogg 1900: 73; Rainbow 1911: 158.
Type material. [Australia: New South Wales] Head of Middle Harbour, Bradley’s collection. Not examined. We were unable to locate the type specimen of T. gigantipes; however, Keyserling’s description and illustrations are adequate to identify the species. Most of Bradley’s collection as referred to by Keyserling and Koch is presumed lost (Framenau 2005) and this species is not listed among the Keyserling types held by the Zoologisches Museum Hamburg (Rack 1961), nor is it recorded in the Natural History Museum London (J. Beccaloni pers. comm.). These are the main collections holding Keyserling’s Australian specimens.

Diagnosis. The legs of C. gigantipes are far longer than those of related species currently known from Australia or New Zealand: the femur and tibia of leg I are each longer than (male) or subequal to (female) the total body length (Figs 2, 5). Male, pedipalp tibia elongate and subequal to cymbium length (Fig. 11; half or a third as long in C. veruculata (Fig. 16) and C. blattea, respectively). Epigynum with a pair of heavily sclerotised, peg-like protrusions that form a deep U-shape in posterior view (Fig. 19); the shape of these protrusions distinguishes the species from C. veruculata in which the protrusions are smaller and more horn-shaped. For comparison with C. veruculata and C. blattea refer to Merrett & Rowe (1961: figs. 1–7); Dondale (1966: figs 1B–E); Vink et al. (2009: figs 1–6); Paquin et al. (2010: figs 34.7–8, 34.13–14).
