Diagnosis. Can be distinguished from T. obesa   by the facial shield being approximately as high as wide.

Description. Body ( Figs. 26–27) rather large. Colour uniform green or bluish green. Head ( Fig. 31) and frontal shield approximately as high as wide with ridge of frontal shield produced into prominent point at apex. Prothorax with fine scattered tubercles on dorsal surface, more so in female; lateral margin finely denticulate. Fore leg ( Fig. 32) with inner face of coxa without markings, anterior margin with 9–11 small denticles; inner face of fore femur with large dark patch proximal to claw groove (not apparent in some specimens) and three small dark spots distal of claw groove; femora of mid and hind legs often orange red in proximal half. Wings of male longer than abdomen, those of female shorter than abdomen; ventral surface of costal area of tegmen dark bluish grey in anterior half; discoidal area completely opaque in female, only partly so in male; hind wing with costal and discoidal area yellowish green, anal area hyaline.Abdomen of female with posterior margin of fourth and particularly fifth sternite curved ventrally. Male genitalia ( Fig. 33) with moderately elongate apr, narrowed distally; pa with anterior hook-like projection and posterior knob-like projection; distal projections of dpr of moderate length, anterior one longer than posterior one.

Measurements (mm). Body length, 3 53–75, ♀ 59–75. Pronotum length, 3 19–20, ♀ 21–26. Pronotum width, 3 5.5–6, ♀ 7–9. Fore coxa length, 3 12–15, ♀ 15–19. Fore femur length, 3 13–16, ♀ 18–22. Hind femur length, 3 14.5–15, ♀ 17–22. Hind tibia length, 3 15–16, ♀ 17–23. Tegmen length, 3 42–54, ♀ 28–38.

Immature stages. First two instars dark coloured and antlike in behaviour and appearance. Ootheca squat, cream to sandy orange in colour. Appears to be mostly laid on the ground, usually attached to a piece of timber. The peculiar form of abdominal sternites 4–5 in the female may play a role in ootheca deposition.

Distribution and habits. Found across the arid regions of southern and central Australia ( Fig. 46). Appears to be most commonly associated with mallee vegetation where the blue green body colour blends well with the leaves of certain mallee eucalypts. I have observed numerous individuals of this species, in nature and captivity, and never seen the cryptic behaviour displayed by members of the genus Sphodropoda   . Adult females are commonly caught in pitfall traps, probably in the process of seeking oviposition sites.This would also suggest they are not capable of effective flight.

Remarks. The original description appears to be based on one specimen although this is not specified. One of the two female syntypes is labelled type, the other cotype. These are printed labels and there is no indication that they were placed there by the author. Therefore, I have decided not to designate a lectotype. A syntype specimen is illustrated by Sjöstedt (1930, plate 8, fig. 1)
