Body length 102 mm.   FIGURE 118.  Podacanthus keyiholotype male (ANIC), 102 mm. Head: Large, as broad as long. Eyes large, dark brown. Three ocelli present. Antennae longer than fore femora, with 23 segments, second segment very shortened. Thorax: Pronotum slightly longer than head, double swelling above central indentation. Mesonotum more than twice length of pronotum (unusual in the genus, normally about the same length or slightly longer), with eleven conspicuous tubercles; smaller tubercles present laterally and ventrally (latter also applies to metathorax). Metanotum longer than mesonotum. Wings: Fore wings long and leaf-like, inner margin with a whitish streak. Hind wings long, whitish with a pale pink tinge, reaching up to 7th abdominal segment. Abdomen: Elongate. 8 thabdominal segment reduced in size, 8 th–10 thsegments about equal. Anal segment curved, split into large double lobed structure, with incurving arms, typical in  Podacanthus. Subgenital plate large, bulbous, rounded at tip, not reaching end of 9 thabdominal segment. Cerci very long, leaf-like, rounded at tip. Legs: Moderately long. Mid and hind femora spiny.  Paratypemales (38). As in holotypeexcept for variation in size. Body length 83–103 mm(two large nymphs excluded from measurements).   FIGURES 119–122.  Podacanthus keyiholotype male. 119.head and thorax, dorsal view. 120.end of abdomen, dorsal view. 121.end of abdomen, lateral view. 122.end of abdomen, ventral view.   Paratypefemales (27)( Figs. 123–127). Sometimes shorter than male (not unusual in  Podacanthus wilkinsonias well), except much plumper, with other differences as follows: hind wings pink (usually at least veins); inner margin of pre-anal part of wings, with a large yellowish blotch. Anal segment tapered, triangular incised at tip; supraanal plate visible. Operculum large, boat-shaped, tapered to rounded tip, almost reading end of anal segment. Cerci shorter than male, but longer than anal segment. Body length 91–113 mm, excluding one large nymph.   FIGURE 123.  Podacanthus keyifemale paratype (ANIC) 113 mm. Egg ( Fig. 128). Capsule pale grey or brown, oval, hairy. With a fine net-like sculpturing. Large for the size of the species, central micropylar plate rather narrow, broadened at base, occupying half length of capsule. Capitulum broad, uneven. Capsule length 4.7 mm, width 2.5 mm, height 3 mm. Slightly unusual for the genus, which normally has large, bold sculpturing.   Holotype ♂, Western Australia, Perth, Floreat Park,  1.x.1962, J. A. Mahon, M.J.D. White cytol. Prep.

Apart from the typeseries, widespread in the WA suburbs ( Western Australian Museum).  Notes Whilst superficially similar to  P. wilkinsoniin size, easily distinguished by the elongate appearance of  keyi(  wilkinsoniare stocky, besides having dark brown areas on fore wings and pre-anal part of hind wings). The other known  Podacanthusspeciesare rather larger insects; all other species have the mesonotum shorter than in  keyi.According to data labels, the host food plant is  Eucalyptus loxophlebaand  E. gomphocephala(Myrtaceae); specimens accepted  E. marginatain captivity.  Derivation of name Named after the late Kenneth H.L. Key (1911–2002, ex. ANIC), well known to phasmid enthusiasts for the sections in both editions of ‘The Insects of Australia’. As mentioned in the acknowledgements, his legacy is the outstanding collection of Australian orthopteroid insects built up in ANIC. 1962-10-01 A, ANIC Mahon, M. J. D & Prep.
