Relationships of Myopsocus unduosus (Hagen) 
Badonnel (1967) constructed a classification of the species from 
Madagascar, and Smithers and Thornton (1974) augmented it to 
include many of the Old World species. M. unduosus, being known 
only from the male, and presenting such unique male characters as 
the phallosome with its basal half a simple rod, and the hypandrium 
with two distal fields of heavy setae, does not seem to fit into any of 
the groups that have been proposed. Smithers and Thornton (1974) 
noted that numerous other species could not be placed in their 
classification due to paucity of information. 
Augmented Diagnosis of Lichenomima Enderlein 
Species assigned to Lichenomima (assigned to Myopsocus by 
most authors since Badonnel 1967) have veins Rs and M joined by a 
crossvein in the hindwing. Correlated with this character are 
absence of a median style of the phallosome (possible exception: L. 
ariasi New) and female subgenital plate distally with a transverse 
sclerite, more or less separate from the main plate, and never termi- 
nating in a single process tapering posteriorly. 
Species assignable to Lichenomima appear to be those listed by 
Smithers (1967) plus the following: 
ampla Smithers & Thornton 1974 (from Myopsocus ), New 
Guinea 
ariasi New 1979 (from Myopsocus ), Brazil 
capeneri Smithers 1973 (from Myopsocus ), South Africa 
chelata Thornton & Woo 1973 (from Myopsocus ), Galapagos 
Islands 
clypeofasciata Mockford 1974 (from Myopsocus ), Cuba 
coloradensis Banks 1907 (from Myopsocus ), Colorado 
elongata Thornton 1960 (from Myopsocus ), Hong Kong 
machadoi Badonnel 1977 (from Myopsocus ), Angola 
medialis Thornton 1981 (from Myopsocus ), Fiji 
posterior Navas 1927 (from Psocus), Costa Rica 
pulchella New & Thornton 1975 (from Myopsocus ), Brazil 
sanguensis New 1973 (from Myopsocus ), Nepal 
varia Navas 1927 (from Amphigerontia ), Costa Rica 
Note. — Myopsocus medialis Thornton (1981), assignable to Lich- 
enomima on the basis of hindwing venation, appears to be so differ- 
ent in several other features as to merit a distinct genus.
