Description
(male): length: 10.0; wing: 7.5×2.2.
Head
: post-cranium, vertex and frons shining black with no pruinosity; ventral postcranium with scattered pale setae; postorbitals reduced to short hairs, white ventrally, black dorsally; face as wide as frons and covered with silvery pruinosity; palp yellow with white setae, curved and slightly clavate; proboscis yellow with dark brown apex, elongate, length about one and a half head height, and projecting ventrally; antenna dark brown.
Thorax
: pleura and anterior mesonotum mostly redbrown; anterior mesonotum red, interdigitating with black posterior mesonotum (

Abdomen
: terga 1 and 2 reddish, remainder of abdomen black; cuticle glabrous, without pruinosity; segment 7 with well-developed tergum and sternum, tergum 7 not excavated; nor differentiated from segments anteriad; tergum 8 reduced to narrow band; sternum 8 unmodified; hypopygium (

unknown.
Remarks
.
Bandella maxi
is known only from submontane rainforest above
1000 m
on Mt. Lewis, in the
Queensland
wet tropics. It has a greatly expanded and keel-like hypopygium.
However, male abdominal segments 7 and 8 are relatively unmodified, and therefore plesiomorphic with respect to the other
Bandella
species.
This species is named for the collector, Max Moulds.
