REDESCRIPTION OF THE TYPE SPECIES OF 
MYOPSOCUS, M. UNDUOSUS (HAGEN), AND 
RESULTING NOMENCLATURAL CHANGES IN GENERA 
AND SPECIES OF MYOPSOCIDAE (PSOCOPTERA)*

The assignment of species to the major genera in the Family 
Myopsocidae has been hampered by lack of detailed morphological 
information about the types of these genera. The genera involved 
are Myopsocus Hagen, Lichenomima Enderlein, Phlotodes Ender- 
lein, and Rhaptoneura Enderlein. 
Enderlein’s (1910) genera were based entirely on wing venational 
characters. Some of these have later proven to be variable and of 
questionable value (Badonnel 1967). Roesler (1944) synonymized 
Phlotodes and Rhaptoneura at the generic level but maintained 
them as subgenera. Badonnel (1955) stated that genitalic characters 
justify the maintenance of Rhaptoneura and Phlotodes as genera 
but did not show what characters were involved. Smithers (1964) 
assigned all species which might fall in the genera Myopsocus, 
Lichenomima, Phlotodes, and Rhaptoneura to Myopsocus until the 
types could be studied. Badonnel (1967) following Enderlein (1910) 
and Roesler (1944) assigned to Myopsocus all species with Rs and 
M joined by a crossvein in the hindwing, thus synonymizing 
Lichenomima with Myopsocus, and assigned all species in which Rs 
and M in the hindwing are fused for a distance to Phlotodes, thus 
synonymizing Rhaptoneura with Phlotodes. 
The present paper reports diagnostic features of the type of 
Myopsocus unduosus (Hagen), the type species of Myopsocus 
(Enderlein 1910). Genus Myopsocus is re-diagnosed on the basis of 
this examination, and an augmented diagnosis of Lichenomima is 
included. Generic synonymies are revised, and the species now 
assigned to Myopsocus and Lichenomima are listed.
