This species is apparently rather elusive as it is one of the largest insects in Micronesia but also one of the rarest (as it is only known from four museum specimens). This poorly known species is only represented by old/degraded specimens collected between 1940 and 1980 and therefore it is one of only two species excluded from our molecular analysis (the other being

Both sexes have the unique feature of having the interior protibial lobe reduced on the distal half with a majority of the lobe and the widest point on the proximal half only (Fig.
