Psyche 
[March 
of rotundulum, in which the wings only reach the apex of tergite 2 
and are not folded. Distinct anal flap present on wings of pustuli- 
ferum and rotundulum, probably in other species also. Folding 
pattern of fully-developed hind wing similar to that illustrated for 
Anthobium (=Eusphalerum) sorbi by Forbes (1926: fig. 33), the first 
transverse fold being a hinge by which the costal margin is turned 
about 90°. (In an individual, the hinges of the two wings usually 
form slightly different angles.) 
Abdomen with most of segment 8 and part of genital segment 
exposed; first visible sternite is sternite 3. Tergites 4 or 5 to 8 fairly 
well to well-sclerotized, spiracles located in tergites 4 or 5 to 8, in 
membrane beside tergites 1 to 3 or 4; one pair of paratergites on 
each of segments 3 to 6 or 7, may be partly or entirely fused with 
sternites laterally (as almost complete fusion in fig. 47); tergite(s) 4 
or 4 and 5 with paired patches of medially-directed microtrichia 
which cover about half to nearly all of the surface of the tergites 
(figs. 40-43); tergite 7 with an apical fringe (“palisade fringe” of 
some authors) as in fig. 45. Intersegmental membranes with a brick 
wall pattern of irregular plates as in fig. 44, some dorsal plates with 
posterior teeth as shown. Sternite 2 extending up around sides of 
abdomen slightly, but in tenuicorne appearing to be membranous, 
its limits therefore not determinable. Sternites 2 and 3 with small 
intimately associated intercoxal processes, more or less as in fig. 48, 
sternite 3 (at least in pustuliferum and rotundulum) with a trans- 
verse fold across its middle one-fourth to one-half about at posterior 
margin of intercoxal process (this area not visible in other species 
because of telescoping of abdomens). Sternite 3 without distinct 
coxal cavities, metacoxae simply protruding parallel to sternite’s 
surface; at least in some species with a ridge near basal margin and, 
like sternites 4 to 5 or 6, a curved ridge just inside each lateral 
margin. Sternite 8 with anterior median projection (see figs. 49, 
61-65) associated with a gland system, similar to that described by 
Klinger and Maschwitz (1977). In at least three species ( rotundulum , 
pecki, pustuliferum ) gland reservoir extending anteriorly as far as 
anterior margin of segment 5. 
Male: Peg setae apparently absent from trochanters, femora, and 
tibiae; first four segments of protarsus slightly broadened, spatulate 
setae in pairs on segments 1 to 3 of protarsus (figs. 22, 25), and 
singly on first two (possibly three in pecki ) segments of mesotarsus
