Figs. 1-3. Structures of Philotarsid and Pseudocaeciliid psocids. Figs. 1 and 2. 
Distal margin of labrum in posterior view showing sensilla (scale = 0.05 mm). Fig. 1 . 
Latrobiella paraguttata Thornton and New 9< type 1:11 sensilla of three series, a, c, 
and e lying immediately under a posterior membranous fold (m), b and d lying 
deeper, perhaps on inner surface of second membranous fold (nT), and f lying on 
anterior surface. Fig. 2. Zelandopsocus cumulus Thornton and New $, type 2: nine 
sensilla in two series, five shown in solid lines on posterior surface, four shown in 
dashed lines on anterior surface. Fig. 3. Zelandopsocus cumulus 9, clunium, epi- 
proct, and left paraproct in lateral view; r = setigerous ridge or flap of epiproct (scale 
= 0.2 mm). 
valvula bearing a blunt-tipped process medio-distally. Included 
genus: Brvopsoeus Thornton, Wong, and Smithers. 
Several unusual features were noted for Brvopsoeus by Thornton, 
Wong, and Smithers (1977). These include hardening and fusion of 
female abdominal terga, a setose forewing membrane, and possibly 
wings of macropterous males being held flat over the abdomen at 
rest, those of one side overlapping those of the other. These charac- 
ters, along with the unusual habitat of moss, serve to strengthen the 
view that this genus should be assigned its own family. The two 
species which have been assigned to Brvopsoeus differ rather 
markedly, and it is not clear that all of the generic characters 
(derived from the type species) apply to both species.
