Acanthostichus brevinodis

Nothing is known about the biology of  and it is only known from males. Most specimens appear to have been captured in light traps, as moth scales are often attached. The male captured by Porter was loose on the ground in daylight. (Mackay 1996)

Identification
Mackay (1996) - Similar to Acanthostichus fuscipennis, except the petiole is very short (Fig. 68) and truncate anteriorly. Occasionally the anterior edge of the node of the petiole is somewhat higher than the remainder of the petiole. It lacks the bluish reflections of A. fuscipennis. This is a very distinct, small species in which the shape of the petiole (Fig. 67) easily distinguishes it from all other described species. This species does not represent the undescribed male of any other species as it is a member of the brevicornis species complex and the males of all of the species which share the distribution are known.
