Psyche 
[June-September 
characterized by having six or more ventral manubrial 
setae in adult animals. In 1946 Gisin pointed out that this 
species was probably identical with Kseneman’s F. dip- 
lopthalma var. T etropthalma. Since Kseneman had indicated 
that in his opinion this was a matter of population vari- 
ation and thus not subspecific in rank, this name would 
fall under the category of “infrasubspecific form” accord- 
ing to the rules “A name given to any infrasubspecific form 
if elevated to subspecific or specific rank by a subsequent 
reviser shall rank in its new status for purposes of priority 
as from the date on which it was so elevated, and shall 
be attributed to the author by whom it was so elevated.” 
Thus Folsomia tetropthalma becomes a junior synonym of 
F- penicula. 
The species is extremely common in Lebanon and Syria, 
and in a variety of habitats. The specimens at hand display 
characteristics which destroy the separation shown between 
this species and multiseta by Stach (1947). The table below 
indicates how this species violates both sets of limitations :

Leb. penicula

In view of this I feel best to consider multiseta a synonym 
of the locally variable penicula.
