Nycterimyia Lichtwardt 
This extraordinary genus of flies is at present known in 
seven species: N. dohrni (Wandolleck) of Sumatra, Mafor, 1 
and the Andaman Islands; N. horni Lichtwardt, of Northern 
Queensland; N. kerteszi Lichtwardt, N. fenestro-clatrata, and N. 
fenestro-inornata Lichtwardt, of Formosa; N. capensis Bezzi, of 
Natal; and the New Guinean species described below. Although 
all species are closely allied, the distribution of the genus is 
extremely discontinuous. 
The structure of the antennae appears to be quite different 
in N. papuana from what has been described in other species. 
Of A. dohrni , Wandolleck (Entom. Nachricht., XXIII, 1897, p. 
251) wrote originally: “Fuhler 3-gliedrig, gelb, drittes Glied 
stabformig mit welligen Conturen; and der Spitze tragt es ein 
ganz kurzes, feines, dqrchsichtiges Tastharchen.” Lichtwardt 
(Deutsch. Entom. Zeitschr., 1909, p. 647) says of the same 
species: “An den Fiihlern ist das dritte Glied nach vorn ver- 
breitert und mit einer stiftartigen, starken, apikalen Borste 
versehen.” Bezzi (Ann. South African Mus., XIX, 1924, p. 
169) describes the antennae of N. capensis as “very short, with 
the third joint rounded and smaller than the preceding one; 
they are pale yellowish like the rather thick style, which is 
twice as long as the antenna/’ In my example of N. papuana 
(Fig. 2a), the third joint is extremely slender and ends in a 
narrower, seta-like portion, although no trace of suture could be 
discovered between the basal and apical sections. It agrees 
therefore best with Wandolleck’s account, but I can not find 
a differentiated tactile hair at the tip. I am inclined to believe 
that the “thick style” in Bezzi’s description of A. capensis 
represents the true third antennal segment, while his “third 
joint” is what I describe as the second segment.
