present specimens are similar to the forms described and 
figured from Ardeche by Delamare in the absence of an 
inner tooth and the proportions of the dens, as well as in 
the existence of an occasional triangular p.a.o. However, 
in the chaetotaxy of the manubrial venter and the structure 
of the unguis, the present specimens are much more like 
those figured by Stach for Candida.

Folsomia cavicola Cassagnau & Delamare 
Folsomia cavicola P. Cassagnau & Cl. Delamare Deboutteville op. cit. 
: 38 1,382. 
I have not recovered this species but it appears to be 
distinguished from Candida in Lebanon by the absence of an 
apical filament on the unguis, presence of a large internal 
ungual tooth, and the blunt mucronal teeth. Also the apical 
tooth is strongly upcurved in contrast to the straight tooth 
of Candida. Known only from Ghita cave. 
Folsomia sp. 
A single specimen taken (damaged) from the Nahr 
Array in Lebanon merits mention. The p.a.o. is divided 
by a prominent listel, and the last three abdominal segments 
are weakly fused. The furcula is short and the mucro 
three-toothed. The eyes appear to be eight/side but are 
hard to distinguish. While this is probably a new species 
of Folsomia the single damaged specimen is insufficient 
material for its description.

The specimens at hand appear quite similar to those 
described and figured by Linnianemi, and Stach. There 
appears to be some variation in the setae on the tenaculum 
(most of the present forms have two setae) and in the 
eyes. In a number of specimens it appears that eyes G. and 
H are definitely smaller than the remainder. The size of 
the basalmost mucronal tooth is variable.
