Distinguishing features

Elongate, very slender body and wingless. Females are brown/green, have tiny spines on the head and the terminal abdominal segments are distinctive. Males are smaller and green.

The photographed specimens differ from Brock's (2000) description of other specimens (all females) from north Queensland, including the holotype from Lizard Island, in that they lack a pair of spines between the eyes but Brock notes that character is variable.

Thanks to Matthew Connors for the identification of the three records from Jan 2019 and earlier, and of the specimen photographed by Mike Bok.


  • Up to 10 cm (body length of females observed at Lizard Island)


  • Wingspan data is not yet available.
