Hah. Groote Eylandt, Northern Territory (N. B. Tindale). Type, I. 14056. 



This species, which in life is dark brown, flew freely to lights in my camp 

 at Yetiba, Groote Eylandt, on sultry nights, all through the "wet" season 

 (December to March). It was very active, flying and running around the table 

 and the rim of the lamp, often capturing small flies and other insects which had 

 been attracted to the light. Owing to its quickness it was very difficult to 

 capture. It is the smallest mantis so far known. "Maia" is derived from a 

 Groote Eylandt (Ingura) native word meaning "active." We have a single 

 male from Darwin.
