Chaetoceras poi sp. n.
8mm. This species resembles labecula in the male but is larger. The
female is more heavily and uniformly irrorated with bluish black. The forewing
margin is slightly more produced centrally than in labecula. The male
genitalia have the valves straighter, less downcurved than in labecula, and
the ribbon of sclerotisation is sinuous rather than arcuate. Both species have
the bilobed distal margin of the eighth abdominal sternite narrowly and deeply
notched between the rounded lobes whereas in the type species the space between
the processes, which are more rod-like, is much wider. The female genitalia are
described in the generic account above.
