Size:2.5 mm. Range: This is the only species of the genus in the Western Hemisphere. It has been colleted around Brownsville, TX and penninsular Florida. Outside the U.S. it occurs in Cuba, Mexico,
Guatemala and Belize. Habitat: persistant dead leaves of various
plants, also on trunks and branches of trees.
Size: ~ 3 mm. Range outside Texas: Eastern U.S. west to Arkansas Habitat: Bark
and leaves of
deciduous trees and on exposed outcrops. Males are rare
except at a few sites in the U.S.
Size: ~1.6 mm. Range outside Texas: Eastern
U.S.; less common in the southwest. Habitat:

macropterous form of this species and I would be
delighted to encounter it.

northeast; Habitat: Can occur in grain mills, bird nests, even
herbaria.
I have only found it on palms (Sabal
minor) at Aquarena Springs. Males and females look very much

Size: 1.1 mm. Range: First recorded from the Botanical Gardens of
Calcutta, India by Ian W. B. Thornton and S. K. Wong, "Some

To the right is the macropterous
female (length 1.7 mm). In my
experience, this form is rarer than the apterous one. In this family,
the wings are held flat over the abdomen, not roof-like as in the
Psocomorpha. Dr.
Mockford says that this individual from Gonzales Co. shows much more
patterning on the head than specimens in far south Texas.
Size: male ~ 1.1 mm, female ~ 1.3 mm Range: unknown Habitat: Leaf litter This un-described species lacks the backwards "U" shaped marks along the lateral edge of the abdomen. This species often occurs with Tapinella maculata.

Size:0.7 mm Range: single site Habitat: leaf litter This species has not been found in Texas but it is so remarkable that I had to include it. This remarkable species was discovered by Tim King. "It is the first living species of its genus, known otherwise only from Sphaeropsocus kuenowii Hagen, a fossil species from the Baltic amber (Eocene)."

In this species, the males are micropterous and the females are either macropterous or micropterous. The tiny male has a dark clunial comb (visible in a dissecting microscope) which identifies it as mature. I once observed a male approaching a female and vibrating his body rhythmically as a prelude to courtship. This species is likely very common throughout Texas.
