MICROLEFIDOPTERA OE NEW GUINEA 
recorded also from outside New Guinea, viz., Proactenis, with two species in 
Java and one in New Guinea, and Proselena with one Australian and one 
New Guinean species. Three other small genera do not occur in New 
Guinea, viz., Diactenis with some six Indian species, Paraselena with one 
Australian and one Australian and New Zealand species, and Palaeotoma 
with one Australian species. In total 91 endemic species of this family 
were recorded from the Papuan region as far, and several more await 
description. 
The same can be said of the tribe Zacoriscini of the Tortricidae, the 
distribution of which was already discussed in the systematic part (part I, 
pages 35 and 37). 
As a further proof of the independence of the Papuan fauna, in particular 
of that of the Central Region, we may briefly review the most important 
endemic genera. The most remarkable of these is perhaps the Zacoriscine 
Chionothremma, a diurnal Tortricid with the singular shining silvery colour 
and jet-black markings perhaps in consequence of or as an adaptation to, 
these life-liabits. Chionothremma possesses 29 species of which 24 were 
collected in the Central Region, 22 being new to science. This genus 
represents a zoocentre in New Guinea as remarkable and rich as that of 
the birds of paradise. 
The endemic genera of the Tortricidae worth mentioning in this place 
are Anisotenes, being the second rich one, comprising 17 modestly coloured 
species, all from the Central Region; Rhomboceros, Aplastoceros and 
Tremophora, each with five species; the Eucosminae Metaschistis with 
seven, and Peridaedala with four species; and the Yponomeutid Iriania 
with some ten species (only seven of which could be identified on account 
of the bad condition of these small and delicate insects). 
Now we will consider the entire collection by briefly reviewing each 
family represented. 
Remarks on the families 
The Alucitidae are characteristic by their world- wide distribution, 
and probably represent an ancient group. It was not surprising to find 
four cosmopolitan genera among our material ; however, one is represented 
by a Papuan species already described, while three others have developed 
two new species each. Of the other three genera Diacrotricha may be of 
Indian origin, with pioneers reaching Christmas Island, New Guinea, and 
even the Solomon Islands, Steganodactyla shows exactly the opposite: 
Papuan, with one widely distributed species extending through South 
Asia as far as Mauritius and the Comoro Islands; Fletcher ella, at last, is 
endemic and probably of Indian relationship. 
The Phaloniidae are represented by Arachniotes, an endemic genus, 
and by Clysiana which is small but widely distributed, with several Indian 
and a few Javanese species, and may be of Palaearctic origin.
